B. Periodical service points

1. Cylinder fins

Dust clogging between the cylinder fins will cause

overheating of the engine. Periodically check and

clean the cylinder fins after removing the air

cleaner and the cylinder cover. When installing the

cylinder cover, make sure that switch wires and

grommets are positioned correctly in place.

2. Fuel filter

(1) Using a wire hook, take out the filter from the

filler port.

(2) Disassemble the filter and wash with gasoline,

or replace with a new one if needed.

Note:

• After removing the filter, use a pinch to hold

the end of the suction pipe.

• When assembling the filter, take care not to

allow filter fibers or dust inside the suction

pipe.

3. Oil tank

With a wire hook, take out the oil filter through the

filler port and clean in gasoline. When putting the

filter back into the tank, make sure that it comes to

the front right corner. Also clean off dirt in the tank.

4. Spark plug

Clean the electrodes with a wire brush and reset

the gap to .025 in. as necessary.

Note:

Use a Champion RCJ-7Y or NGK BPMR7A for

replacement.

5. Sprocket

Check for cracks and for excessive wear interfering

with the chain drive. If the wearing is found

obviously, replace it with a new one. Never fit a

new chain on a worn sprocket, or a worn chain on

a new sprocket.

6. Front and Rear dampers

Replace if adhered part is peeled or crack is

observed on the rubber part.
