Hello People. My names B.J. I just bought a blaster that needs work. Im planning on rebuilding from the ground up. The first thing Im going to do is pull the engine and rebuild. I want to put a big bore kit on and I was wondering on which one to get. Ive seen a couple different ones like the 240, and the 265. Whick one should I get and what brand? I dont want to buy a crappy brand. If im going to put time and money in I want to have nice stuff. lol. I plan on doing flat track and just some riding around with it so I need a kit that will run good with riding hard during races and will run good for cruising. Thanks for the help.
