Pre-ride InspectionTo ensure safety, it is your responsibility toperform a pre-ride inspection and make surethat any problem you find is corrected. A pre-ride inspection is a must, not only for safety, butbecause having a breakdown, or even a flat tire,can be a major inconvenience.

Refer to the Competition Handbook for procedures.

Competitive riding can be tough on a vehicle,so it’s important to inspect your vehicle andcorrect any problems you find before each ride.

Check the following before each ride:● Engine oil level● Fuel line for condition● Coolant for proper level● Cooling system and hoses for condition● Spark plug for proper heat range, carbon

fouling and spark plug wire terminal forlooseness

● Air cleaner for condition and contamination

● Clutch lever freeplay● Breather drain for cleaning● Steering head bearing and related parts for

condition● Throttle operation● Tires for damage or improper inflation pressure● Spokes for looseness● Rim locks for looseness● Front and rear suspension for proper operation● Front and rear brakes, check operation● Drive chain for correct slack and adequate

lubrication● Drive chain sliders and drive chain rollers for

damage or wear● Exhaust pipe/Muffler for looseness● Every possible part for looseness (such as

cylinder head bolts, engine mounting bolts/nuts, axle nuts, handlebar holder bolts, forkbridge pinch bolts, drive chain adjuster, locknuts, drive chain roller bolt/nut, wire harnessconnectors)

Caring for Your VehicleFrequent cleaning and polishing is important toensure the life of your Honda. A clean vehiclemakes it easier to spot potential problems.While you're cleaning, be sure to look fordamage, wear, and gasoline or oil leaks.

WashingAllow the engine, muffler, brakes, and otherhigh-temperature parts to cool before washing.1. Rinse your vehicle thoroughly using a low

pressure garden hose to remove loose dirt.2. If necessary, use a sponge or a soft towel

with mild cleaner to remove road grime.u Clean the plastic components with extra

care to avoid scratching them.Avoid directing water into the air cleaner,muffler, and electrical parts.

u Do not use steel wool to clean the frameas it could damage or discolor the framesurface. Scotch Brite Hand Pad #7447-

maroon is for removing stains on thenon-coated aluminum frame only.

3. Thoroughly rinse your vehicle with plenty ofclean water and dry with a soft, clean cloth.

4. After the vehicle dries, lubricate any movingparts.u Make sure that no lubricant spills onto

the brakes or tires. Brake discs, pads,drum or shoes contaminated with oil willsuffer greatly reduced brakingeffectiveness and can lead to a crash.

5. Lubricate the drive chain immediately afterwashing and drying the vehicle.

6. Apply a coat of wax to prevent corrosion.u Avoid products that contain harsh

detergents or chemical solvents. Thesecan damage the metal, paint, and plasticon your vehicle.Keep the wax clear of the tires and brakes.

61Continued

If you use a truck or motorcycle trailer totransport your vehicle, we recommend that youfollow these guidelines:● Use a loading ramp.● Relieve the fuel pressure and drain the fuel

from the fuel tank into an approved gasolinecontainer.

● Secure the vehicle in an upright position,using motorcycle tie-down straps. Avoidusing rope, which can loosen and allow thevehicle to fall over.

To secure your vehicle, brace the front wheelagainst the front of the truck bed or trailer rail.Attach the lower ends of two straps to the tie-down hooks on truck bed or trailer rail. Attachthe upper ends of the straps to the handlebar(one on the right side, the other on the left),close to the fork.

Check that the tie-down straps do not contactany control cables or electrical wiring.

Tighten both straps until the front suspension iscompressed about half-way. Too much pressureis unnecessary and could damage the fork seals.

Use another tie-down strap to keep the rear ofthe vehicle from moving.

We recommend that you do not transport yourvehicle on its side. This can damage the vehicle,and leaking gasoline could be a hazard.
