ears22 Posted May 15, 2009 Share Posted May 15, 2009 Hi there has any one got any ideas on why my R1 is missfiring. I am a mechanic and have tested the plugs, coil packs, coil pack wiring loom, injectors, injector wiring loom, all seem fine. I got a feeling it has burnt a valve out but just wanted to see if anyone had come across a common fault or a one off fault that I have not checked before I remove the engine and strip it down. Any help would be much appricated. Link to comment Share on other sites More sharing options...
Moderator Airhead Posted May 15, 2009 Moderator Share Posted May 15, 2009 Why not do a compression test? This will indicate a burned valve as low compression. Link to comment Share on other sites More sharing options...

Was going to be my next port of call was just woundering if any one had come across any other faults that would cause this. Thanks for your time though mate.
