Im most likley rebuilding my 951 cc (98 xp) this season or the end of it. I looked at a couple kits and heard some things about some too. I have heard SBT's arent the best...and wiseco is a bit pricier. Could i just order the full gasket kit for my motor from SBT and just get pistons/rings from wiseco? And i saw there are different bore sizes? like up to 1017? I would have to send out my whole core to get bored wouldnt i then probably have to grab stronger connecting rods and a crank...Oh and does anyone make high compression pistons? or dont you do that to 2 strokes. I was hoping with my rebuild to maybe up the power:stupid::hurray:
