    My XBS has been stalling on idle lately. Installed new plugs and wires but stalling has continued. Performed TPS reset and noticed my voltage never went to 0.0. Lowest the volts went is 0.98. Not sure if that is an issue. Bike appears to run normal with just the slightest twist of the throttle.

    Screenshot as bike is beginning to stall.

    putting the TPS reset aside your idle RPM is too low (881 rpm)

    I agree with rchuff reset afv to 100 and let bike run for a minute . Give it time to adjust , and bump rpms up a little after bike is warmed up

    881rpm is the bike going into a stall.

    Bike has a race ecm. Not sure which exhaust its tuned for as I bought the bike with it.

    Just clarifying, I know there certain things you can't do on a race ecm. I assume adjusting the afv is one you can do?

    Yes i just had that problem. Bike would stAll went I went to take off, and after a good run and stop at light then take off it would stall, also felt heavy on the front like the front brakes were on, my afv jumped to 116. So I reset back to 100 and good to go. It seems to happen every now and then. Give it a try

    No dice with AFV set to 100.

    I'm positive it's a fuel issue.

    set your tps to 5.1% at 4.6 degrees and set afv to 120 and see what happens .do not adjust idle till your cold start enrichment is at or below 100. then let us know what happens.
