Hi, i am building a 250r racer. I am starting with a stock 88 Honda
250r. I plan on modifieding everything execpt the frame. I started to make my list of mods, but i stoped when i got to the engine. I don't now what to do with it. I want to race mx in the 250 class to start
out and get experience. In the 250 class u are aloud to have a .060 over bore. I want a full on race motor. Who should I have work on my motor? I was thinging about Curtis Sparks or LRD. I want to have the most horsepower i can get with going only .060 over. Can i get like 55-60hp out of it? I would like to stay with 310 AND THE 330 BIG BORE FOURTAXS. On mine i would like to haveeverything done: Mill head, porting, 19cc domes, .060 over bore, 39mm carb,and everything else that can be done! What else can be done?
Thanks

 

I have heard that CT Racing does good work. The two companies that you mentioned are also very good. Give one of them a call and they can tell you everything you need to know about getting the most out of your motor. They could probably give you a list of mods a mile long! Good Luck
