    Lately my bike has been hart to start when warmed up. Cold it starts like it should. It don't do it every time but enough that I grit my teeth when ever I start it when warm.

    I have read threads on the compensator fixing the problem and about the cylinder temp. sensor possibly being bad. Checked the codes and this is what I found. The first one is the VSS which was supposed to have been replaced the other two I have no idea on.

    Any thoughts?

    Joe,
    You have no codes. The 68924-07 is the security module being a Host.
    The 67261-08 is the Speedo interface being a Host.
    67459 is the ECM being a Host.

    Your clean. You have to troubleshoot it without the help of codes.

    I would test the temp sensor first. Are you running quality brand fuel. Mileage on bike?

    Shell or Chevron

    Is there an ohmic reading that can be used to check the sensor?

    Thanks Hoople!

    Haven't checked the wires but new plugs about 500 miles ago.

    "The problem it gives you when it needs cleaning is an erratic idle speed and stalling and usually does not set a code unless they fail."

    I have neither problem. When cold, starts like it should. Warm / hot mostly sounds like someone described as a thresher. Will spit back most times.

    Thanks TQ.

    Joe, If your temp sensor is part # 32446-99 like mine is,, here are the numbers.

    104F= 1442 ohms
    122F = 965 ohms
    140F= 661 ohms
    158F = 462 ohms
    176F = 329 ohms
    194F = 238 ohms
    212F = 175 ohms.

    I am surprise HD stops at 212F. I am sure I have read much lower readings than 175 ohms. Run the bike hard, kill engine and see what the sensor reads while unplugged using a meter. I would expect ~130 ohms, maybe even lower.

    Also. I agree with what TQ said about the IAC. A Post from other day said you can spray after taking off A/C.
