I know it's been a while, but I just wanted to give an update on the stalling problem that I had. I took it to the dealer to get it checked out and when he tried to change some settings on the ECU it wouldn't take them. Defective ECU!! 2-1/2 weeks later the new ECU is installed with the stalling fix and the injector settings are leaned out a little. Although I haven't raced a hare scramble with the new ECU yet, I did ride some open strip mine areas and it seems better. I only stalled it once, but it was my fault.
