Right now I'm building a new 250r for mx and was wondering what you guys thought the best engine kit was for mx. As of right now I'm thinking about the CT 330 powervalve for open class or a Turner kit for stock class. I haven't really decided what class I want to be in yet because I used to race in the stock class but I think I might want to switch to the opens. Any help would be greatly appreciated, thanks.

 

Stay away from CT motors. IF you want a big bore PV get it from DUNCAN!
