can someone tell me some good sites to get performance parts for honda ATV's. I still want my 450 but I have aquired the 300ex frame and parts for sure. if it is still there monday after work I am buying a running 86 350x engine, and I found on ebay a completed listing for a white bros 2m overbore 10.75:1cr piston whivch makes it a 369 I think. but no current listings and only that one completed, are they very uncommon or something? and anybody make one with something around a 12:1? or should I stay down around 10.75:1 to be completey safe off of pump gas? I searched to try and find stores on google and checked so many links but none of them were really any good.
