so i have and fmf performaxx and i was woundering what would happen if i took all the discs out and left if open ended would i need to rejet i think it would help alot if you knew the size of the jet that i have in it now but idk it does already pop a little on decelleration SP and i think that means its running lean correct me if im wrong so what would happen.

nevermind guys i went to the fmf site and under the question section it said about discs in a megamaxx and says not to run less than eight but thanks to those of you who replyed and raptorracer45 better tell your friend to put his back in idk y not to run less than 8 but im gonna go with what the website says and go with 11 which is what i put back in cause it says ideal number is 11-13.
