:fingers-crossed-emoI have a (Barn find) 2000 RSV MM only 10k mile on it. Last month when I first got it a ran a can a sea foam as recommended but I always thought is ran a little ruff. But with past BMW experience most bike runs a little ruff. Well after some late night reading someone here said that they run surprisingly good on only 3 cylinders. Well, mine does. After starting it and running it for 30 seconds my left rear (#1) cylinder exhaust pipe is still cold. I pulled the plug and it looks oily and not firing, all the rest look great. I stuck the removed plug in the wire and cranked it and it has spark. I checked the compression and its fine. I suspect a plugged carb? When I pulled the gas tank I also noticed that the Carb for the cylinder that is not running has a nice coating of Oil/Gas seepage crust. I ask you, What would the guru’s do next?
