The part is well packed and presents good. All the necessary parts are included for a piston and cam swap out. It was super easy to insert the piston and rings into the sleeve with the sleeve slightly tapered on the bottom. No special tools needed. All the parts fitted well.
We only changed this part and kept everything else standard - including the exhaust.
On first run of the motor, it would not idle well. An adjustment to the idling helped clear up the issue. As time went on the fuel injection adjusted the idling and it stabilized.
There is a power increase from the 110cc even with the standard exhaust.
This part seem to be a better option even cost wise when you need to replace the piston, against buying the standard 110cc parts.
