I'm not going by what the manual says because thats for like a pro rider, so im looking for advice. I dont race this bike, but ride it pretty good. How many hours should i have between pistons?

I have seen people with 30+ hours on their 150R's. I built one that ran the DirtBike 24 hour ride and that engine has been in 2 other races plus countless hours of play riding.
Honestly if you are just play riding, you can prolly go for a while before you have to repiston yer engine.
the info I posted is just what I've experienced.

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
