This cast iron cylinder is a great upgrade for you 3-port engine cases. The Polini 177 cylinder makes a massive amount of torque as well as higher RPMs. If you need a cylinder to move you quickly up a hill or help that sidecar move down the road this kit is for you. For advanced tuners, using this kit in combo with a long stroke cut crank and a cylinder spacer you can achieve 187cc monster. I would also recommend a 24/24 carb and SIP Road 2.0 or 3.0.
*This is a performance part and as such requires setup during installation like, setting ring gap, chamfering ports, squish check, proper jetting, timing, break in periods, and often other components to be replaced to become reliable. Manufacturers label these as race parts and do not warranty race parts except when a part is defective before installation.*
