  • 2003 V92C driveability issue

    Just bought a 2003 V92C as at 71 YOA, my ‘12 XC is getting a little heavy at parking lot speeds.

    It appears seller wasn’t honest about the bikes history (go figure). Odometer shows only 8,100+ miles, but bike has way more than that. It looks like previous owner(s) that performed maintenance weren’t up to the task. No mods to wiring I can discern. No aftermarket lights or other parts I can find. I knew it would be a project and I have one, it seems 😳. It needs items like a windshield, seat, oil change, etc, but if I can’t get it fixed, I don’t want to invest the additional money.

    Anyway, bike has a miss at idle and surges between 1,000-2,000 RPM. Runs strong above that, it seems. I ran three tanks with Gumout Injector Cleaner, no change. Starts fine when cold and running temperature. No black or white smoke from exhaust when on the throttle.

    New plugs. New K&N air filter. Replaced throttle body rubber caps. Cleaned throttle body (increased idle rpm by about 350 rpm, now idles at 950-1,000RPM). Probed throttle body boots-seem firm. RPM doesn’t change when carb cleaner sprayed on boots. Does this mean that the IAC hoses are good, too? Fuel pressure deadheads @50PSI, running @52. Changed spark plug wires with XC. – no change. Performed ECM/TPS “reset”. Alternator output @13.9V. New battery, bike cranks fine. Appears to be getting 50MPG.

    Looking for next steps I should undertake. Thanks in advance.

    If there was an authorized Victory dealer nearby this could be as easy as plugging it into their Victory proprietary computer and richening the Air/Fuel mixture.

    Without the aid of that hardware and software we’ll have to start talking about adding an aftermarket fuel controller. I just did a TC a week ago that needed a Doebeck style controller to add the required fuel.

    A hand held AFR meter will be invaluable in this process.

      I just submitted a request for service to you to see if I can get on your schedule sometime over the winter/early spring. Thanks DC
