Big bore kit yet to be fitted
Big bore kit, all looks very good and of high quality except the piston rings aren't very good, im a professional Mechanic 30 + years experience this is for a little tinker project im teacher my son, it's been ported to within a thousand of an inch of which it can take so soon time to fit it

Perfect fit
I have this on an 150cc atv and works better than ever It ran like new, better, I got more compression then ever, and the gaskets were good to. I would highly recommend this thanks

Läuft.
Vorausgesetzt, man weiß wie und was man da tut, läuft der Zylinder seit dem Einbau ohne Probleme.Die ersten paar hundert Kilometer hat er runter und läuft perfekt.
