Good the inside of that part has a bronze bushing-it absorbs motor oil-get it off -clean it up- soak it (the bronze part with motor oil, 30wt) 3 hours is best then it should be oiled about every 5 hours of use. You just give it an oiling before you store it after riding and that will let it soak up more. 5 hours of run time is a good point to clean and re-oil the chain-and change the motor oil so you can just do all 3 at the same time.
