Third it has a slight stumble when I give the gas a good twist but it recovers good. It seems like it wants to stall at idle like every 10 sec or so. The bike actually stalled out on me yesterday while at a stop sign. I'm have a scanner on the way to hopefully figure that out. I had the flash to the ecu done along with the FTECU active tune with the wide band O2 sensor and the Graves exhaust.įirst issue is the check engine light wont go away. I've been having some minor issues that we have been trying to troubleshoot.
