Good product

Everything you'll need is in this kit but I did have to put a 115 main jet in the carb to get it to run right in the mid range

Much more power!

I seized up my 250xc and it was only like $80 more dollars to buy the big bore kit as opposed to buying a new top end and new cylinder. I wish it would have came with instructions as you have to put together the cylinder and power valve components yourself but at least theres good ol' youtube! My bike totes my 250lb butt around much better now. Hey theres a big log in the trail, just a blip of the throttle and thats that.

Great

Had everything but the wrist pin bearing in the kit. That was the only flaw I found in the whole deal. No biggie Motosport had me one in two days. I also would recommend a nihilo deck height tool. Mine took 3 of 4 supplied base gaskets. Cheap insurance
