CB250 TWISTER
Cleaning and Lubricating
After inspecting the slack, clean the chain and
sprockets while rotating the rear wheel. Use dry cloth
with chain cleaner designed specifically for O-ring
chains, or neutral detergent. Use a soft brush if the
chain is dirty.
After cleaning, wipe dry and lubricate with the
recommended lubricant.
Recommended lubricant:
Drive Drive chain lubricant designed
specifically for O-ring chains
If not available, use SAE 80 or 90 gear oil
Do not use a steam cleaner, a high pressure cleaner,
a wire brush, volatile solvent such as petrol and
benzene, abrasive cleaner, chain cleaner or lubricant
NOT designed specifically for O-ring chains as these
can damage the rubber O-ring seals.
Avoid getting lubricant on the brakes or tyres.
Avoid applying excess chain lubricant to prevent spray
onto your clothes and the motorcycle.
Crankcase Breather
Service more frequently when riding in rain, at
full throttle, or after the motorcycle is washed or
overturned. Service if the deposit level can be seen
in the transparent section of the drain tube.
If the drain tube overflows, the air filter may become
contaminated with engine oil causing poor engine
performance (page 52).
