2-34 PERIODIC MAINTENANCE
Periodic Maintenance Procedures
If a special lubricant is not available, a heavy oil such as
SAE90 is preferred to a lighter oil because it will stay on
the chain longer and provide better lubrication.
Apply oil to the sides of the rollers so that oil will penetrate
into the rollers and bushings.
Wipe off any excess oil.

Sprocket Wear Inspection
Visually inspect the front and rear sprocket teeth for wear
If they are worn as illustrated or damaged, replace the
[A] Worn Tooth (Engine Sprocket)
[B] Worn Tooth (Rear Sprocket)
[C] Direction of Rotation
If a sprocket requires replacement, the chain is proba-
bly worn also. When replacing a sprocket, inspect the
Rear Sprocket Warp (Runout) Inspection
Using the jack, raise the rear wheel off the ground (see
Special Tool - Jack: 57001-1238
Set a dial gauge [A] against the rear sprocket [B] near the
teeth as shown.
Rotate [C] the rear wheel to measure the sprocket runout
(warp). The difference between the highest and lowest
dial gauge readings is the amount of runout (warp).
If the runout exceeds the service limit, replace the rear

Brake Lever and Pedal Position Adjustment
Adjust the front brake lever to suit you.
Slide the brake lever dust cover [A] out of place.
Loosen the adjuster locknut [B] and turn the adjuster [C]
to either side.
After adjustment, tighten the locknut.
Always maintain proper brake adjustment. If ad-
justment is improper, the brake could drag and
overheat. This could damage the brake assembly
and possibly lock the wheel resulting in loss of
TIR 0.4 mm (0.016 in.) or less
TIR 0.5 mm (0.020 in.)
