My 2012 WR450 stalls occasionally at slow speeds when I let off the throttle and gas it again real quick and was wondering if it has anything to do with having a Rekluse Z Start Pro clutch? I never road it with the stock clutch. Is anyone else having this problem? I do have the GYTR ECM and have tried many different maps but nothing helps. The exhaust and air cleaner are both uncorked and I have stock gearing.
