[QUOTE="AJ Waggoner, post: 28271, member: 16665"] In an un related but sort of related topic.. I just had a call today on boring the 50cc bikes in the Stock classes. the polini if it is a borable cylinder can be bored .080 over and my understanding is a certain model already comes bored over? but ANY of the other 50's that are nikisil CANNOT be bored .080 over and re-Nikisiled. the rule is in stock that a minicycle can be overbored .080 but ANY cylinder that is Nikisiled or similar coated cannot be overbored and relined.
