I purchased a 2001 929 4 months ago and absolutely love the thing (until yesterday). I had the bike down to replace fork seals and neck bearings for the last cpl days and while reassembling found a loose ignition wire that I soldered back on. Got the bike started yesterday and it ran like crap (wouldn't hardly pull itself) and I felt it had fouled a plug (replaced plugs 400 miles ago) so I pulled the plugs and found no issues there. I put it all back together and the problem is worse, won't start at all and flames out the exhaust. I consider myself pretty mechanical, I just don't have much experience with this bike. I do have the manual and I didn't see much there. I'm thinking it is either ECU or ignition related. Any help is appreciated.

 

I can't help but to think that if it was running fine before you tweaked on that wire, that wire has something to do with it.

 

I'm with shaver, and it also sounds like you have a fuel problem. If it's shooting flames, then it's got to have unburnt gas coming out the exhaust

 

And running rich. Mine does this after I had the valves adjusted. (which I highly reccomend doing at the appropriate mileage) The timing chain and tensioner were also changed...and my bike is as rich as Scott Pioli! I'm getting ready to put a PCIII on, and have it tuned...you may want to do the same, especially if you have an aftermarket exhaust...that's normally the main culprit on these 929's.

 

befor you buy a PCIII look at the rapid-bike it's the new kid on the block.
