    So I have my 2004 xb12s that usually runs good. Recently my bike will start right up and then start to idle fluctuate. When I go to give it gas it will die on me. The only way I was able to get it to move was really ride the clutch out and give it a bunch of gas real quick. I cleaned and re oiled my air filter and it ran fine at first but is doing it again. If the bike runs for a few minutes the problem seems to go away. Does this just seem like a tps reset problem or something more? I will do a tps reset when I get my laptop with all my software on it on Sunday. For now I am just letting the bike sit. Any help would be much appreciated.

    Change the tps sensor, two bikes just did it to me in a week, must be the weather??

    I would start with a tps reset and see if that helps. Have you fine any recent mods that affect your gas/air flow? I only ask because when I modded my exhaust and airbox my bike started doing the same thing. I increased the values in ecmspy for the cold start enrichment and it cured the problem

    I'd start simple & change Spark Plugs - NGK# DCPR9EIX. Then move on to the technical stuff...

    I just did the plugs, my muffler needs repacking soon could that cause this problem?

    Now on top of all this crap. Someone tipped my damn bike over in the parking lot last night...
