172cc Pm Tuning Pro1 Cylinder Kit 125-180cc 2T
£445.00
fits with original water jacket ( off centre head )
comes with x3 base gaskets and the necessary o rings for the head.
these produce around 20-25hp on my dyno depending on the rest of the components fitted to the engine.
powerful out the box cylinder with plenty of material round the ports, so potential of 35+ HP with the right cylinder port work!
New small end bearing is advised!
