okbeast Posted August 26, 2013 Report Share Posted August 26, 2013 Ok so can I run my cool head with the domes I have after boring or do I have to get bigger domes to match the bore size If you're not going to a "big bore" size (68mm +) then you should be good to go.

twostrokin Posted August 26, 2013 Author Report Share Posted August 26, 2013 Yes the power just don't do it for me no more Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted August 27, 2013 Report Share Posted August 27, 2013 you don't bore a 2 stroke for power......you gain almost nothing. You save the bores for when it needs rebuilds......and it will need rebuilds. Again.....don't bore for power....there is none...........4strokes make power by boring, not 2 strokes.
