IntroductionWelcome to the eleventh (2008) edition of the MSA Kart Race Yearbook. We hope that all users willfind it helpful and informative. Produced with the agreement and support of all kart associations andthe kart trade it includes details of all nationally recognised classes. This yearbook is reviewed andrevised each year and with an agreed intention towards an inbuilt stability. Copies are distributed to allMSA licensed kart competitors, officials and clubs and also included with ‘Starting in Karting’ Packs.Additional copies may be obtained from the MSA at £8.50 each including postage. We welcome allpractical suggestions for the next issue which should be directed to the MSA.

How to use this bookClasses are detailed in their prime form as defined by the sponsoring organisation followed by notesto describe additional regulations used by an association or championship, e.g. Cadet (Comer) is aMSA class; ABkC, BSA, ASKC, NKRA or commercial additional regulations are covered in thefootnotes.Where junior and senior classes share significant commonality the main class regulations will be foundin the junior section and differences for the senior class are identified in the text, e.g. Formula TKM.General competition, technical and safety regulations remain in the MSA Competitors Yearbook (BlueBook) which must be referred to in conjunction with the regulations reproduced herein and whichtakes precedence. Full details of international regulations are contained in the CIK Yearbook whichshould also be referred to for applicable classes. For convenience we have included relevant extractsfrom the draft 2008 CIK Yearbook where known. Competitors intending to enter International eventsor classes should obtain a copy of the CIK Yearbook and ensure up to date compliance. Regulation changes from the previous year are shaded.

General Notes1. Silencing. Sound level requirements for British karting are constantly under review.Competitors should ensure that their equipment conforms to the levels defined in MSA regulations oras amended by venue local requirements. Where appropriate additional regulations are given inAppendix 3.

2. Weights. All classes show minimum weights and these are defined as the minimumweight acceptable for the kart plus driver and equipment (race condition) at any time. Class weightsmay be amended upwards for club or championship events. Where such a change is detailed inthese regulations this will be signified by an asterisk (*).

3. Class Categories. The following table details main kart race categories and theirappropriate classifications. The classification provides guidance for clubs as to which classes may beamalgamated if required for race grids. It also provides guidance for the performance categories inwhich any new class should be made compatible.

4. Class Regulations. Queries on the class regulations should be sent in the first instanceto the class promoter, as shown in the ‘Affiliation’ section of each class.

All clubs must specify the classes they offer in their supplementary or championship regulations with areference to the MSA Kart Race Yearbook and their particular association’s regulations, and have areference to the source of the class regulations if found elsewhere e.g.

‘TECHNICAL REGULATIONS. MSA 2008 Specific karting technical regulations apply together with the2008 (insert your club’s association) regulations within the 2008 MSA Kart Race Yearbook and theSR’s for the meeting. ELIGIBLE CLASSES: All (insert your club’s association) classes plus ‘xx’ and ‘yy’ are offered, exceptthat Formula ‘zz’ is not offered. The regulations for all classes offered may be found in the 2008 MSAKart Race Yearbook. Additionally Formula ‘??’ is offered under MSA Regulation K 5, the classregulations are available from: (name and address of class promoter).’

B3.0 Group Junior and Senior

B3.1 Class Formula TKM

Affiliation Commercial – Tal-Ko/ABkC

B3.2 Introduction. Commercial economy class for juniors and seniors with chassis andengine price control. Super One ABkC Championship class. The Junior age classes have beenmodified into three weight/restrictor size bands and it is intended that normally all three bands willrace together for the same trophies with blue number plates. Where a club has sufficient numbersthey may if they wish run different weight/restrictor bands of the Junior class on separate grids. Thenew Junior Extreme class is introduced as a premier championship class which it is hoped will buildin strength into a club class.

The optional use of clutches for all TKM classes is permitted (mandatory for Junior Extreme). All

15



seniors should now be on Extreme class engines, though any that are not should race within thenormal grid. The class regulations have been developed by Tal-Ko with the help of Formula TKMdrivers , the BKIA, and the ABkC. The control of the class regulations rest with Tal-Ko and theseregulations are printed with the permission of Tal-Ko. The regulations are the same as those publishedby Tal-Ko. Additional regulations for the ABkC follow the main text. Further copies of the fullregulations are available from Tal-Ko, 54 Sunderland Road, Sandy, Bedfordshire SG19 1QY.Tel. 01767 682020. While long term stability is at the heart of the classes, in the interests of fairness,clarity, safety, and drivers, Tal-Ko reserves the right to agree with the MSA clarifications and changesto regulations at short notice if required.

B3.3 Chassis.

B3.3.1 Homologated chassis with side pods and front fairing. Each manufacturer may onlyproduce two homologated chassis at any one time. When a manufacturer already has twohomologated chassis, if he homologates a new design, he cannot continue to produce chassis to theold homologation. From 1.1.2007 a new chassis homologation period came into force. Manufacturersmay only produce and sell a maximum of two homologated model styles at any one time. All kartsmust carry appropriate chassis markings. Reference in this document to 2007 homologation kartsmeans any kart listed in the appendix of karts covered by the 2007 homologation period.

B3.3.2 Drivers may compete in any homologated chassis that appears in Appendix 1, providing itmeets all other requirements.

The next homologation period will commence 1.1.2010.

All chassis made after 1-1-98 must carry the official Formula TKM sequential plate securely riveted tothe brake side bearing hanger together with the manufacturer's stamped chassis number. Thesesequential plates are unique to each kart, non transferable and must only be applied by themanufacturer at the time of manufacture. Karts under the 1998, 2001, 2004 and 2007 homologationlist must not have detachable plates carrying the manufacturer's chassis number and year ofmanufacture. Chassis number must incorporate the year of manufacture. In the case of lost/damagedsequential plates, a special procedure is used to issue replacements via the manufacturer.

B3.3.3 Chassis to be constructed from magnetic steel tubing, cross section free. The method ofwelding/brazing is free but for all main chassis joins welding/brazing is obligatory - i.e. no clamping,sliding members or torsional adjustments including additional bolt-in torsion bars. The use of any typeof hydraulic or similar damping device for any purpose is specifically prohibited.

B3.3.4 Engine must be mounted to the right hand side, driver seated facing to the front.

B3.3.5 The rear axle must be of parallel magnetic steel, 30mm nominal diameter, with hubretention. The axle can be either solid or hollow with a minimum nominal parallel wall thicknessthroughout its length of 5mm. It must be supported in two bearings only, using any type of bearingand retention method including cassette type. No other bearings or stiffening devices may beattached to the rear axle for any purpose. It is permitted to use circular collars around the rear axleimmediately next to the axle bearings to prevent axle movement. They must not exceed 16mm inwidth and must be fitted for the sole purpose of axle location. It is permitted to semi-drill the axle forgrub screw location.

B3.3.6 Rear axle quick release fittings are permitted. Hubs may overhang the ends of the rear axleproviding they are expressly designed to do so. Bearing spacers or adapters are permitted.Adjustable rear ride height not permitted. Use of non original parts to effect changed rear ride heightnot permitted. Ride height axle height position as homologated.

B3.3.8 The steering must have non-adjustable castor and camber angles. Castor and camber anglesof the chassis must be as homologated. Steering column may have more than one hole which can beutilised for twin-hole Ackerman type steering operation. Stub axles may contain more than one bolthole in their drag arm. Any hole may be used. Stub axles must be as supplied and fitted to new kartsby the manufacturer homologating the kart. In other respects such as length of axle shaft and itsangle, and the drag arm length and attachment holes, the stub is free.

The king pin bolts must be centrally positioned in both the frame stub axle mounts and stub axles.

16



The position of the holes must be non adjustable and permanently mounted. Detachable hole insertsnot permitted.

B3.3.9 Front ride height adjustment is permitted by movement of washers/spacers between theframe stub axle mounts and stub axle. On 1998, 2001, 2004 & 2007 homologated chassis themaximum permitted adjustment by this method is 12mm. No modifications may be carried out to thehomologated design to achieve or increase this.

B3.3.10 All karts must have the steering column mounted in such a way that even if the bottomretaining bolt is removed it cannot pull free from its lower bearing.

B3.3.11 The only additions permitted to homologated chassis are: Equipment to meet latest MSAsafety regulations, seat and a Nassau panel, along with the mountings solely concerned with theirfitment.

B3.3.12 The following parts are specifically prohibited: Components made from Kevlar, CarbonFibre, Titanium or other similar exotic materials, other than for the seat and floor tray which is optional.Magnesium front and rear wheel hubs, engine mount, brake disc hub, sprocket carrier and steeringwheel mounting boss may be used. The use of plastic or similar materials for components such aswheels, wheel hubs/bosses, sprocket and brake disc carriers is expressly forbidden.

B3.3.13 Additional bolt on seat stays/mountings are permitted position and style free.

B3.3.14 Use of CIK homologated crash tested sidepods and front fairing is mandatory and mustconform to MSA technical regulations. It is permitted to modify the bodywork mounting points on thechassis to accept CIK crash tested bodywork but it must be undertaken in a professional manner.Karts homologated for the period 1998 -2003 inclusive are exempt from the requirement to fit CIKcrash tested bodywork for 2008 only and in these cases where a kart is fitted with a traditional frontbumper incorporating two vertical front uprights it is permitted to make use of the CIK front fairings. Inthis case, as long as the two vertical uprights remain in place, the requirement for an aluminium orsteel securing block as per MSA rule K 156 is waived and the fairing may be attached to the kart byany safe and secure method in two places, not necessarily the CIK type clips. Sidepods mayincorporate suitable holes for starter shaft, airbox trumpet, etc where MSA rules permit.

B3.3.15 Front and rear bumpers must comply to MSA Technical Regulations. Neither mayincorporate adjustable torsion by design. Bolt in type torsion bars are specifically prohibited. Frontbumper must not use rubber, nylon or similar material in its fastenings/mountings. Rear bumper mayuse rubber, nylon or similar material for a maximum of two of its fastenings/mountings to the framebut may be secured by more than these two fixings and may for example have bracing struts to theaxle housing providing these were part of the original homologation.

B3.3.16 Drivers may make use of tank tape, cable ties, thin wire or throttle cable type bowdencable in ensuring that items such as exhaust, bumpers, electrical wiring, chain guard, etc. do notcome off during the course of racing. One or more fixings may be used, however the item used mustonly be there for secondary security and reliability purposes and must not be attached in such amanner that it affects torsional adjustment of the kart or provides any other performance advantage.

B3.3.17 Seat type is free including material. Use of commercially available and manufacturedvariable rigidity adjustment systems for seats is permitted subject to the following criteria. The devicemust be mounted to the seat itself and must not be attached or have contact with the seat mountingpoints or chassis.

B3.4.17 A minimal amount of machining is permitted to the cylinder head subject to stringentconditions, primarily intended to allow rectification of engines that have suffered head damage. Thismust be carried out in line with the drawings laid out in the fiche. Note that the squish angle face of 12degrees plus or minus 1 degree must meet and intersect the liner mating face of the cylinder head atthat angle, with no intermediary angles or curves throughout their full circumference. Any form of step,recess, groove or similar will render the cylinder head illegal since it will not follow the original shape.

B3.4.18 The cylinder head and/or liner mating face(s) must remain flat. If machining or any otheroperation is carried out on the cylinder head and/or liner mating face(s), the mating faces must alwaysremain flat over the full extent of their original surface.

B3.4.19 It is permitted to use helicoil type thread replacements to repair critical engine fixings onthe cylinder head, crankcase and cylinder barrel. Any other type of repair or insert is prohibited. Suchrepairs must not be used to derive any benefit other than rectification of damage. In the case of thespark plug thread, no portion of the helicoil may protrude outside of the normal thread area. The coilmust be inserted to the full length of the original thread and only one continuous coil to be used perrepaired thread. In all cases the size of the repaired threads must remain as standard. On thecarburettor, it is permitted to repair the non-metric threads with M3 or M4 threads providing they donot perform any other function.

B3.4.20 When measuring the inlet and exhaust port timing it is clarified that the maximum contactpressure on the feeler gauge should be only that achieved through finger pressure on either one of thecrank nuts. The dial gauge and fixture block used for this purpose must be tightened down at 13lb/fton each of the two nuts. The nuts/studs must have threads in good condition, lubricated, and withnuts which can be easily moved by finger-only pressure at the point of being tightened.

B3.4.24 When taking measurement of the cylinder head volume, the cylinder head must be fitted tothe engine in the manufacturer’s normal manner with the standard four brass head nuts (or approvedTKM sealing nuts) tightened to 13lb/ft and the two small allen headed bolts tightened to 8lb/ft. Thenuts/studs must have threads in good condition, lubricated, and with nuts/threads which can beeasily moved by finger-only pressure at the point of being tightened. The engine and other testequipment should be at a cold (ambient) temperature of between –5 C and + 50 C. Any readingstaken within this temperature span will be accepted as definitive. The engine must be as raced - e.g.with the same gaskets in position and with no carbon removed from the top of the piston, inside ofthe combustion chamber, etc. The cylinder head may be removed for inspection by an authorisedMSA scrutineer before being replaced for a head volume check. When carrying out such a check usemust be made of the authorised and TKM marked measuring plug. Procedure should follow that laiddown by Tal-Ko. An ‘A’ grade burette must be used with oil which meets the specification (availablefrom Tal-Ko). Once it is determined that the oil level has reached the top of the measuring plug hole,the reading should be taken within 30 seconds with no more oil added.

B3.4.25 As part of TKM’s commitment to noise reduction, it is mandatory to use effective heatproofwebbing or similar material wrapped around the exhaust flex to help reduce noise.

B3.4.26 The use of purpose designed TKM fin rubbers is mandatory. All new engines are now fittedwith noise reducing fin rubbers as supplied by Tal-Ko. These comprise 10 special rubbers all withTKM logo and either marked H or B to indicate whether for head or barrel. Competitors must use afull set of these rubbers, which may be fitted to older engines. The use of more than 10 rubbers is

allowed but not advised. Only TKM rubbers permitted. Where fins have become broken on an engineit is permitted to remove excess sections of the rubbers at this point.

B3.4.27 The use of one or more TKM manufactured with TKM logo special steel cylinder headretaining nuts with hole for sealing wire is permitted, even if sealing is not required. Use of such nutsmay be mandatory at championship meetings as specified in their regulations.

B3.4.28 The use of both piston rings is mandatory. The rings must at all times remain predominatelyfree to operate in the manner in which they were designed and supplied. It is the responsibility of thedriver to ensure that the rings are not ‘coked’ in place with carbon or prevented from their normal‘spring’ effect by other methods. The rings should be appropriate to the piston size used and have amaximum ring gap of 0.5mm when measured with the ring placed squarely 5-10mm down from thetop of the cylinder bore. This rule does not apply on Extreme engines with only one piston ring.

B3.4.29 Where possible it is recommended that the use of officially sanctioned and part numberedTal-Ko gauges is used in checking engine measurements. In the case of any discrepancy results usingTKM approved gauges will be taken as definitive.

B3.4.30 It is permitted to use a TKM manufactured with TKM logo flex ring to help increase the lifeof the exhaust flex.

B3.4.31 Permitted Re-bore (Extreme Specification Engines Only). It is permitted to re-bore thebarrel in order to take new TKM Extreme oversize pistons 54.25 – 54.75mm. This modification maybe carried out to any age engine. It is also permissible to carry out minor machining to the cylinderhead to match as detailed in the latest fiche additions. The pistons in these Extreme engines will haveonly one piston ring. In all other respects normal Formula TKM rules apply.

B3.5 Transmission

B3.5.1 The drive must be direct, i.e. the crankshaft and rear axle are connected only by a singlelength of chain. No belt drive, reduction gears, etc., permitted. Engine sprocket to be 9, 10, or 11tooth.

APPENDIX 3 – Silencing

1. Intake Silencers

As from 1.1.2009 all classes will be required to have filtered air boxes.

1.1 In 100cc classes other than Senior and Junior Formula TKM only CIK-FIA homologatedboxes are permitted for ABkC championship events. British made boxes conforming to the CIKspecification may be used in club meetings by all 100cc classes other than the Formula TKM classes.

CIK noise boxes conform to the following nominal specification:

a) The intake silencer must make a petrol tight fit with the carburettor interface.

b) The minimum volume of the silencer must be 1000cc.

c) The material must be non splinterable plastic.

d) Have a maximum of two openings for the air intake.

e) The air intakes must be unmodified and be a maximum of 23mm diameter for Direct Driveand Junior Gearbox karts and maximum of 30mm diameter for all other gearbox karts.

1.2 A CIK homologated box must not be modified with the exception of drilling holes in themounting flange and drilling a maximum of two holes in the box wall, for the sole purpose of mountingon gearbox karts. The carburettor adapter is free providing a petrol tight joint is made between thebox and the carburettor.

All gearbox karts must have a CIK intake box correctly fitted, or one that is approved by the ABkC forthat class.

1.3 In order to obtain ABkC approval 10 boxes must be presented for inspection. The boxesmust be professionally produced devices complete with production diagrams. During a noise test,which is made on an overhead microphone, static and on both sides of the kart, the box must give atleast equal noise attenuation to a CIK intake box fitted to the same engine. The lap times with the boxon test must be comparable with lap times using a CIK box. A sample of the box will be retained byABkC as a reference.

An ABkC approved box must be permanently marked with its ABkC approval code in order to bedeemed legal for use.

1.4 The following intake boxes have been approved by the ABkC for use on all gearbox kartswith the exception of the Europa, Junior Gearbox, ICC (UK) and Super ICC classes:

Single Cylinder FIS/2RV Motivation Design and Development Filtered Induction Silencer SystemAssembly, side fitting for rotary valve gearbox class engines, fitted with Pipercross foam filter element.Approval expires 31/12/2010.

Twin Cylinder FIS/2T Motivation Design and Development Filtered Induction Silencer SystemAssembly, side fitting for rotary valve twin cylinder gearbox class engines, fitted with Pipercross foamfilter elements. Approval expires 31/12/2010.

Single Cylinder FIS/2PR Motivation Design and Development Filtered Induction Silencer SystemAssembly, for reed valve or piston port induction single cylinder gearbox engines, fitted withPipercross foam filter element. Approval expires 31/12/2010. It must be fitted with the intake trumpetsfacing towards the ground. Not applicable to 250E.

Note that the intake box designated GB1/94 is no longer approved

1.5 Formula 210. All air entering the carburettor must flow through either a K & N cylindricalfilter, Part No. RU 0840, or a K & N conical filter, Part No. RU 9220. These intake filters must only beused with an exhaust muffler conforming to 20.8.5.2. An air box conforming to the CIK specificationor an air box approved by the ABkC may also be used.

2. Exhaust Silencers

2.1 Unless specifically authorised exhaust lengths may not be varied whilst the kart is inmotion. Any such system must be failsafe in operation, not present a hazard and incorporate a

55



measurable reduction in sound level. It should be noted that authorisation will only be given forapplications for Formula 100 National as the majority of classes do not allow such systems.

2.2 The following regulations 2.3 and 2.4 are mandatory for all gearbox classes except Europa125 Class B. The following regulation 2.5 is mandatory for all gearbox classes except 125 EuropaClass B and 210 National.

2.3 Karts shall be provided with an exhaust silencer lying approximately parallel to the rear axleof the kart, and fed by a gas-tight tubed link pipe of a minimum 300mm length from the exit of theexpansion chamber to the entrance of the silencer/muffler. In Formula 250E at least one silencer mustlie approximately parallel to the axle.

2.4 The link pipe must have a bend of approximately 180 degrees for engines exhaust portedto the rear. For engines exhaust ported to the front, the bend must be between approximately 45degrees and approximately 180 degrees. Formula 250E is exempt from these bend anglerequirements.

2.5 The muffler must have an external minimum cross-section 100mm and a minimumcanister length of 380mm. The canister must be used with muffling material and/or baffling plates tobe an efficient silencer. The exhaust exit diameter of the canister must be no greater than 38mm.

2.6 Formula 250E: Mufflers as above, two to be fitted.

2.7 Formula 210. All gasses leaving the engine must pass through a muffler with minimumactive length 47.5cm, external minimum cross-section 100mm, with an inner tube of maximum bore4.0cm which must have perforations over the majority of its complete length. The muffler must beconnected to the exhaust tailpipe by a nominal 180 degree bend or flexible pipe.

3. General

3.1 The black and orange flag will be shown during a race to signify that a kart is exceedingthe sound level limit for the class or circuit. Drivers must return to the pits and report to the Clerk ofthe Course. If the silencing system is broken during a race the driver must stop in a safe place assoon as is practical and not attempt to continue or return to the pits.

3.2 Attention must be given to silencing systems maintenance. With the published reductionsto permitted levels it is important that flex connections and joints are checked regularly and madegood. Exhaust silencers that are capable of being repacked, such as Rotax 125 Max, can suffer fromdeclining performance and it is essential that repacking is carried out in accordance withmanufacturers instructions.

APPENDIX 4 – ABkC Additional Regulations to the MSA Kart Race Handbook – 2008

A. General

The Association of British Kart Clubs (ABkC) was formed in 1990 to act as an interface between kartclubs and the sports governing body, the MSA, with whom there is a high degree of discussion andco-operation. The clubs are represented by a Steering Group, which is elected each year during theABkC AGM, which is held in the Autumn.

The regulations contained in the 2008 Kart Race Yearbook and referred to as ABkC affiliations and/orABkC rules represent the class structure being used by the Association in its direct drive and gearboxnational championships. All clubs affiliated to ABkC have agreed to use these regulations fortheir race meetings. Without this co-operation it would be impossible for drivers to movefrom club to club during the racing season and find the same race classes.

This document should be used as an addition to the Club’s Supplementary Regulations and used asthe reference point for the classes.

All ABkC clubs must run their meetings according to the regulations set down by the MSA. Theofficials and all safety regulations must conform to the current MSA Yearbook, the ABkC specificregulations are only the class regulations. The ABkC reserves the right to conform to changes in CIKregulations that occur after the publication of the 2008 Kart Race Yearbook.

Information printed in italics relates to regulations that will come into force in the future should themember Clubs agree.

Regulations which contain numerals in brackets e.g. (K 140) are references taken from the MSAMotor Sports Yearbook.

Changes are shaded.

Definitions

The ABkC Kart Racing Regulations, were until 1997 published separately and were known as the“Green Book”. These regulations are now incorporated into the 2008 MSA Kart Race Handbook,known as the “Gold Book”, published by the MSA on behalf of them and all the Kart Associations.

The MSA British Motor Sports Yearbook, is hereafter called the “Blue Book”

The CIK Yearbook of Karting Sport, is hereafter called the “Yellow Book” and is available on the CIKwebsite http://www.cikfia.com/

ABkC National Championships will be organised by the Super One, BRDC Stars of Tomorrow andNKF for Super Four classes or other series as may be decided by the Steering Group for thoseexisting popular classes and selected CIK classes as indicated under the Class Regulations.

E. Lap Scoring and Points Scheme Recommendations

After a survey of the procedures used by member clubs when lap scoring and calculating the grids forthe finals during a meeting the following suggestions are made to enable the drivers to understand thesystem.

E.1 System (A) The first placed driver in any heat will be given 0 points, 2nd place 2 points, 3rdplace 3 points and so on until the last placed driver, or System (B), the first placed driver will be giventhe number of points equal to the maximum number on the grid plus two, the second placed driverthe maximum less two, the third the maximum less three and so on.

E.2 (A) A driver who fails to start a race will take 1 point more than the number of drivers thatstarted the race, or (B) I point less than the maximum number of starters.

E.2.1 If the grid is part of a meeting when drivers may not be racing in every grid used for thatclass, then a non finishing driver will take (A) 1 point more or (B) 1 points less, than the largest startinggrid used in that class.

E.2.2 Drivers who fail to finish may be given points according to their positions on the lap charts.

E.3 A driver who is excluded from a race will take (A) 1 point more, or (B) 1 point less, than thenumber of drivers that started a race, calculated in exactly the way as in E 2.1 The C of C may decideto increase this penalty under certain circumstances (MSA Yearbook Section C(d) 3).

E.4 Lap scoring, when transponders are not being used, should take the form of at least threepeople independently observing the drivers, this is important should a dispute arise in order that amajority decision may be made. The practice of one person “calling” the drivers is not encouraged!

E.5 In order to enable the judicial procedures to proceed with the minimum of complication thelap scoring team are advised to include the following pieces of information on their lap scoring sheets:

a) Race start and finish times.

b) Number of starters and number of finishers.

c) Any other observations pertinent to the result of the race.

E.6 In accordance with MSA Yearbook (B 35) the Chief Lap Scorer will be a judge of fact inrespect of laps completed and finishing order. The Chief Lap Scorer must forward the race finishingorder to the results team and the Clerk of the Course.

F. Transponder Lap Scoring

F.1 The ABkC and MSA has introduced transponder lap scoring. The nominated system for allABkC clubs is the AMB TranX 160 system introduced from 1.1.2001. Every driver will be expected toown a transponder by that time, although clubs may hold back up stocks for hire. Clubs not able tocomply may apply to the ABkC for a waiver.

F.2 The transponder must be fitted in an approximately upright position (ie with the ’R’ clip tothe top) on the back of the seat fitted at a height from the ground at 25cm ±5cm measured to anypoint of the transponder.

F.2.1 Deleted.

F.2.2 Deleted.

F.2.3 Transponders must be mounted in accordance with the manufacturer’s recommendations.

F.2.4 If transponder lap scoring is in use then at least one lap scorer must manually lap scoreeach race per K 47. Transponder decoders must be a certified and approved type.

F.2.5 Where timing by transponder is permitted kart timekeepers must be MSA licensed.

63



G. Tyre Testing Guidelines

G.1 A photo-ionization detector (PID) with a calibration certificate for isobutylene at 100ppmissued in the preceding 12 months may be used for testing for chemical treatment of tyres.

G.2 A reading greater than 3ppm on a PID as described in G.1 with the sampling probe within5mm of any part of the tyre or tread, where the reading is 50% greater than the average readingsfound on tyres from other competitors in the race will be deemed evidence of chemical treatment asper MSA Yearbook (K 134).

G.3 If chemical treatment of tyres is established before the race, using the above technique orany other, the competitor will not be allowed to race as chemically treated tyres may constitute asafety risk and contravenes MSA Yearbook (K 134). If the event regulations allow then the competitormay at the discretion of the chief scrutineer be given the opportunity to change tyre(s).No additional time will be allowed for this.
