macgillivary Posted October 28, 2005 Report Share Posted October 28, 2005 you got it, more compression means your motor cant spin over as fast not sure how much you lose on revs but you do Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted October 28, 2005 Report Share Posted October 28, 2005 i think so..noticeable difference in me and my bros old setups...i had 21cc domes andh eh ad 18cc...more compression is hard on parts, especially in a drag situation...

Fireman-hott Posted October 29, 2005 Report Share Posted October 29, 2005 Like stated above you'll lose some over-rev. But with a highercompression you'll gain some low end if your doing trails and the like. My last trail top end was running 220psi/cylinder. Had gobs of low end torque, coupled with a 2 into 1 pipe and 2 into 1 carb wow. Quote Link to comment Share on other sites More sharing options...
bansheeryder_69 Posted October 29, 2005 Report Share Posted October 29, 2005 just loosen your spark plugs up a little, that should cause your compression to go down a little....right Quote Link to comment Share on other sites More sharing options...
