Hey bluzer, keep your air filter clean and change the oil every 5 hours of use and it will last. If it gets hard to start, check your intake valves clearences and adjust them.

every 5 hours is kinda overkill IMO... i always did mine in 10 hours.... i believe the book calls for 12-15 hours. also, be sure to also check the exhaust valves. with the higher torque of the 4 stroke, check the chain tension regularly as well. if you have a cheaper chain, it will require adjustment more often. good luck with your bike... i think you will love the 4 stroke !!!

the book says to change the engine oil every 15 hours IF you want to change out your piston every 15 hours, the more oil changes you do the longer your engine will last... The oil breaks down from the heat, shockloads and plain use. I would never leave oil in for over 5 hours, unless it was a super high quality full synthetic, then maybe every 6-7 hours.
