newbatv Posted June 7, 2016 Report Share Posted June 7, 2016 just finished a rebuild on my sons 07', installed a new set of vitos power pistons. bike previously had a set of dmc 916's, k&n filter with modded box top. im still finishing up the bike and im waiting to get some supreme fuel as our town doesnt have any available. bike was jetted well before but im wondering if there may be a need to rejet for the vitos? 280 mains, 30 pilots, clip on 2nd position from point on needle with a small spacer underneath the clip. 1.25 turns out on air screws. im thinking of running the bike without a airbox cover. anyone have experience with having to rejet after going to the vitos power pistons? i was also thinking of modding the stock timing plate.

Larry's Shee Posted June 8, 2016 Report Share Posted June 8, 2016 Are you at high elevation? DMC site calls for 330 at sealevel, everything else stock. Looking on Vito's site description States rejeting required, so ya. Anytime you change air in or out you need to rejet. Might be apples and oranges, but put super stock in a Blaster and went up 4-5 sizes, everything else was stock. Quote Link to comment Share on other sites More sharing options...
