Hello all, I am new here and to the CAN-AM world (coming over from Polaris). I recently purchased a USED 2012 Commander 1000xt. pretty decent shape overall. test drove it in a Subdivision so didn't really hammer down on the throttle and it ran good. Made the deal, loaded it on trailer and took it home. next day went for trail ride and to my surprise it won't go over 5000RPMs!!!! it has a Yoshimura FULL exhaust so I am thinking it is just running very lean (that is what it actually sounds like). no check engine light or codes. starts rightup and runs fine until I try to go a little faster. any thing else I should be looking at? I have ordered a Big Gun Fuel Programmer anyway, but would love some help. THANKS!!!
