Coming home from a ride about a month ago, I noticed the check engine light came on, but no error code. I got home just a few minutes later and parked it until the next day. When I tried to start it, it would catch, but run really roughly and then stall out. Restarted it several times, and then had to hold the throttle open to keep the revs up around 2k or else she'd stall again. Once it warms up to 160F-ish it seems to run fine, but then the check engine light comes on and I get the F-R AR SYS ERROR. It's done this everytime I've been on it since then. I haven't modified anything..bike is completely stock. Any suggestions? I'm aware the race ECM will help, but I want to fix the problem before upgrading to it, just in case I ever have to revert back to the stock ECM for whatever reason. Help!! | ||

Have you pulled the airbox - outer and inner? Sounds like the vent line got pulled off the intake manifold. If you pull the outer and inner covers, the vent line is on the right side, should be sticking up 1/2" from the bottom plate. The error means you have a large difference in your front AFR and rear(ECM's "learned fuel"). HTH Z |
