I run my 200cc approx 100 hours per piston. That is with an old, slow guy in the dirt.

For an unrestricted 125cc on the road I would run less than 100 hours, but only experience can tell. Type of riding, type of oil, mixing ratio etc are all factors in the equation. My advice would be tonopen it up at, say 70 hours and inspect.

For a restricted 125? Hard to tell. How resticted is it? 15 HP?
