Hi has anyone come across this issue.. in the past had the map sensors replaced that cured a engine stalling and throttle fault. Bike was working ok afterwards . Decided to swap from sport to race mode and found under heavy acceleration the engine did not fire correctly bogged down and was hesitant. Swapped bak to sport mode and the fault is now still happening, dont know if it was a coincidence the fault arose then or what. Engine runs ok if not under load when using the throttle it seems ( can build up speed slowly and it's not so pronounced). Bike was serviced in august at another dealer which I'm defo not going to use again due to a few issues I had with there service / repair and cost. Anyhow this fault happened out of the blue after changing modes any ideas what this fault maybe ?. Its booked into on yer bike aylesbury in a few weeks but any ideas would be great. It's been a troublesome year so far. Cheers
