I am rebuilding my 88 250r which i will be racing this year in motocross. I was going to send my motor off to MP in oregon but i can afford to, there not expensive i just dont have the extra cash. So i am thinking about having one of the local shops rebuild my bottom end, bore the cylinder, new piston, and put a new clutch in. I proably could do the rebuild myself but i dont want to take a chance on screwing it up. Should i spend the money on having the bottom end rebuilt or should i just do the piston and clutch. My motor was rebuilt once and has 155lbs compression.

And if you had your R bottom end rebuilt what did you pay?
