  • Idle issue

    About 3 weeks ago my 1700 started to die at idle after it was hot. It acts like its out of fuel. Float level is good, idle jet is new, 3 turns out on the screw. I feel like its a fuel issue, but nothing I do is changing it. Ive even insulated the fuel line thinking that heat was effecting it. Ive checked my plugs, they look good, and have spark. Fuel pump is working, and petcock is flowing. I'm at a loss, and maybe even going down the wrong ave. It seems to idle great until it warms up, aroumd 30 miles, and the seconds after it hits idle bam dead. Starts right back up, hell it halls ass with no hiccups. Anyone got any idea where to go form here? Thanks

    Try bypassing the fuel pump and see if it still does it. The pump may be starting to fail. Run some fuel line directly from the petcock to the carb.

    Set the idle at 900 when hot.

      It's not a case of turning the idle up or down. I wish It were that easy. The condition still exists no matter where i set the idle screw.

    First of all... from California. As for your idle issue, I"m wondering if your float needle valve is sticking. They do wear out over time and can stick. Or possibly a gummed up idle jet. Maybe even a clogged fuel filter... Try bypassing the fuel filter by moving the hoses on the side. It does sound like a fuel issue, but to be sure, check the simple things like the battery and coil connectors. Have you done any messing with the wiring lately? I once had a problem where my bike would cut out on the freeway at speeds above 75 and it turned out to be a loose wire because I didn't plug something back in properly. Anyway, just hang in there; I'm sure with all the collective noggins here you'll figure it out eventually.

      Greetings from Illinois
      I am going to replace the needle jet next. I inspected it and no rings or garbage built up. It has a new idle jet. I will bypass the filter and see if that does anything. What is so aggravating as to why I can't figure this out, I work on Harleys for a living! (make jokes here) So I've defiantly been over the simple things. And to add to the aggravation, you can (or should) only change 1 thing at a time. Ride it an hour to get it hot enough, find out that didn't work, let it cool. rinse and repeat ugh.

      I love it! A Harley mechanic riding a roadstar, smartest Harley mechanic I have seen yet! Keep up the great work, I’m sure you can figure it out.

    Welp for those following this post, I figured out my issues. Rear intake gasket was shot. Repaired 2 nights ago, made 4 trips cold to hot and no problem. Thanks for all the help!
