Riding a two stroke motorcycle or puts a strain on the engine. Ideally, you should only need to change oil in once a season, but to be safe; I check the oil before every ride. When the oil needs to be replaced the process takes only a few moments of my time.
First I park the bike on a flat surface and place a drain pan under the engine block. Then I unscrew the drain plug and allow all the two cycle oil to drain out. I put the plug back in place, unscrew the top oil cap, and pour in new yamalube 2 cycle oil. Once the tank is full, I check the dipstick and screw the cap back in place.
