Hi. Don't know if this is the right sub forum, and english is not my first language but i will try my best and hope you understand.
My bike suddenly started running like shit and sounds like an R1 while cylinder #4 is not running. The bike has no problem starting up, but obviously idling rough. While driving it runs like shit, but on full throttle it can suddenly start running on all cylinders for a few seconds before running like shit again. All spark plugs and the coil for cylinder #4 is replaced but still the same issue. Also drained the gas tank and put in new gas. Taking the power commander off didn't help either. Haven't done a compression test yet, but since it runs normal for a few seconds on full throttle i assumed that the cylinder is ok(?). Really don't know what to do or look for now and would love some advice.
