Top End Rebuild

Top end rebuild kits are a great way to get the power back up in your bike, and check the engine is in spec while your at it. A fresh top end means more compression, more compression means more power.

Top end kits usually consist of piston, piston rings, wrist pin, small end bearing (2 strokes), head gasket, base gasket, power valve gaskets (2 stroke), valve stem oil seals and can chain tensioner gaskets (4 stroke).

Each kit should have all the gaskets needed to strip, inspect and rebuild the top end.
