The Race ECM is tuned for the Buell Race Pipe. The fix is a custom mapped ECM for a Drummer. | ||

If you look at the exhaust shootout from American Sport Bike you'll notice all stock based exhausts have a similar flatspot there. | ||

Yep. Pretty normal. I'm actually running the identical setup. I switched from the race pipe to the drummer and am very satisfied. The kit had a larger 'hole' at 4 grand. | ||

Same problem with an open Remus race pipe. Solution keep it between 5000 and the rev limiter. Don't expect to keep your licence too long though. | ||

Special Ops pipe has the same symptom. American sport bike has a map for your setup. |
