When I accelerate hard in the lower gears I've notice a couple of times that the engine will do a hard cut at high RPM's. I'm not thrashing the bike, it's the first time I've owned a Duc. It might sound silly to some but when this happens I'm not looking at the rev counter as I'm not used to a bike with the digital bar counter and haven't noticed a light come on. Can anyone tell me if this cut is just the rev limiter coming in? I haven't had chance to actually look at the Tach when this occurs. I thought the red line was over 10,000 RPM. I could be revving higher than I think.
