Bansh-eman Posted October 23, 2008 Report Share Posted October 23, 2008 boring your motor out will bring up your cc's but the power gain is minimal at best. your best bet is to go with a stroker crank and port work Quote Link to comment Share on other sites More sharing options...

Bansh-eman Posted October 27, 2008 Report Share Posted October 27, 2008 Basically hat the only time you want to bore a small motor like these is when they are damagd or just due for it. For power gains your just wasting time. Quote Link to comment Share on other sites More sharing options...

My bike seized on sand highway. locked up pretty good. tore her down. had to hammer the piston out of the cylinder. it melted to the frikin thing. bored it out put it all together.
