looking to get my 440ex rebuilt this year and was wondering who had what? I like the duncan national kits but I know im going to pay a pretty penny for it. what does everyone else think?? can a 440ex run in the pro production class with a stock frame?? I race mx and run with all 450s I do pretty well right now but the quad needs new piston and has oil leak.
