So the break in for a ringed 2 stroke is very simular to a
4-stroke engine. Your running very lean at low RPM's untill you wear in the rings then lean up and as you run a few tanks through it, pushing the throttle reving the engine after a few tanks.
How does engine vibration factor into the break in. If there's some vibration at higher RPM's are things still tight or just adjustment problems. I am getting some vibration on my TT91 at four stroke (at higher idle) even after 1 gallon of break in.
