| Re: Top end change how often in 150r?
change the oil an change it often,the clutchs are the same as the 85s an they arent made for the abuse of the extra torque of the four stroke so they dirty oil pretty good,i built a motor for a local kid put web cams an a je hi comp pistion in it an he got all summer out of it when i rebuilt it it looked good,re ringed it an put it back together,this was because of his dads religious oil change program,i reccomend every time you clean the air filter change it,oils cheap pistons,valves,cranks,cylinder heads arent,but yea i would reccomend a topend overhaul every winter and just replace as neccesary good luck |
