    2010 FLHTCU rough idle and no power when turning the throttle

    Reccently i rode for about a 1/4 mile and lost all power, I was able to get back home by cruising at idle and with no response from the throttle. Once home I checked the plug wires since it seemed like it was missing a bit. After a doing that it ran fine and I rode for the rest of the day. Today it is doing it again and adjusting the plug wires is not helping, i took out the plugs and they seem fine. The exhaust smells rich and the bike will only idle. No reving at all when you turn the throttle. Please let me know what you think I should check or adjust.

    Re: 2010 FLHTCU rough idle and no power when turning the throttle

    Always look to what was recently done. This issue could be an intake leak. Start the bike up, let it idle, and spray something like wd40, or even water all around the intake seams. If engine idle changes, that's the problem...Also, if that's a fly-by-wire throttle, it could be bad. Your bike should show you codes of what might be wrong. Your service manual will tell you how to read them...

    The Dyno-Jet Power Commander may not be correctly mapped for your configuration.


    Don't force it, get a bigger hammer.
