So my turbo bike has a weird problem at 3k to 5k Rpms at part throttle. It sounds like it’s running on 2 cylinders. Had it on the dyno and does it when in gear and not in gear. The afr stays the same before the bike starts to run funny and after. We changed the afr all over the place and that doesn’t effect the problem. So iam stumped and the dyno guy doesn’t know what to do. It sounds like the ignition is getting cut out. This problem isn’t out of the blue. It’s been like this since I bought it and havent been able to figure it out. I thought it was the tune so I had the bike tuned Thur the ecu. Problem not gone. So I bought a new ecu and problem still there. So I got the ecu flashed and still there. Put a power commander on to get the bike tuned and that still hasn’t changed. Going to pick up a tool that lets me watch the spark going to the spark plug to confirm if it’s losing spark. Bike only acts up part throttle when your in that rpm area. Once your out of that it free revs nice and smooth. But if you hold the Rpms in the area it runs like garbage and sounds like it’s running on half the cylinders. Anyone have any ideas on it could be or what to look into. Any advice would be appreciated.
