LUBRICATION SYSTEM
The motorcycle engine features a dual lubrication system, some parts are force-lubricated by
pressure built up by the oil pump, while others by splashing . A full-flow paper oil filter is provided
in the lubrication system to prolong the engine life.
Maintenance of lubrication system. During the daily inspection, check the oil level in the engine
crankcase and top off the oil if necessary. Warm up the engine before changing the oil. Drain
used oil from the engine and the oil filter cavity after having unscrewed the drain plug and filter
plug. Change oil filter at the intervals shown in the service coupons. Set the rubber sealing bush-
ing into the filter and fit the filter with the bushing onto the adapter of plug, then screw the latter into
the front cover. Now screw in the plug. Fill the engine with 68 oz. oil, or until the top mark of the
dipstick is reached.
Let the engine run for 3 - 5 min. Check the oil level again adding oil up to the top groove of the
dipstick if needed. During motorcycle service, keep oil level in the engine crankcase close to the
top groove of the oil dipstick. Don’t ride the motorcycle if the oil level is below the lower mark of the
dipstick until sufficient oil is added to raise the oil level to the top mark.
Correct position to measure the oil level
Make sure that the dipstick is screwed down securely after checking the oil level.
