I have 2004 BMW 1150RT. I know this forum about GS, but RT has the same engine as GS, and most GS folks do their own maintenance. I need technical advice. I suspect my timing is incorrect. I cannot check static timing at this point, because I have front crash bars' bracket which blocks front plastic cover. I tried to disconnect the bracket and remove cover - no luck. To remove bracket I need to disconnect exhaust pipes (and muffler) :eek1. So, may be I can start troubleshooting it "easy way" first . Question: Did somebody do dynamic ignition test on this engine by timing gun? This how mine ignition timing looks like on slightly warm engine (1 bar on RID) 1000 rpm: http://www.youtube.com/watch?v=7qYTabwwMXA 1050 rpm: http://www.youtube.com/watch?v=jlJt9QueV9o 1100 rpm: http://www.youtube.com/watch?v=EHTi6eojvn4 1250 rpm: http://www.youtube.com/watch?v=Qbesvsn6x5k Comment: After cold start I cannot see timing tab at all in timing window (it is below lower edge of window), chock on - ~1500 RPM, the top end of the tab starts going up and become visible in the window). Is my timing way off - too advanced? I have some videos with timing on fully warmed up engine (5 bars on RID). I will post it later. The upper end of tab goes up ~ up to 1/2 in timing window at 1100 rpm. Keeps going up (retarding) up to ~1400 rpm and then goes down when rpms increase (advancing).
