building a mx/trail 250R ?

[boutin]

well first im looking to jump in a couple mx local races ...so if you have any advice on racing id like to hear it ... I bought +1 houser long travel a arms any advice on a pair of front shocks that arn't that expensive. Should I have the rear shock rebuilt or just buy new? Im having my cylinder bored out due to lack of compression(100psi) and getting a new piston... ive heard wisco pistons are junk ... should i go with something else maybe a higher compression piston or mill the head... i have an rpm counterbalancer where i can adjust the timing should i advance it while jetting the carb or will all this make it run to hot and blow...

wiseco pistons are about the best pistons on the market.
