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.
