  • Carb Question with Pumpless System

    Hi Y'all,

    So, I have a 2004 1700 RoadStar. It was converted to a pumpless system before I bought it. It has a MaxAir air filter/intake on it and RoadHouse pipes. Overall, it seems to run strong, but I'm not convinced that it is running "right." It sometime burbs out of the intake, and the idle drop seems to hang a bit when it's warmed up. I recently changed the plugs and adjusted the valves. I figured the next step would be to play with the carb. I haven't taken it apart yet, but the idle never changed when I turned the pilot from 0 to 3 full turns out, AND the engine never stalled with the pilot turned all the way in. I assumed the pilot adjustment was a fuel adjustment and not air, but I may be mistaken. Please let me know if I'm wrong there.

    Does the pumpless system require a different size pilot jet? Does the current pilot jet seem too large?

    Thanks in advance.

    Jet size remains the same. You should verify what jets exactly are in there as well as measure your float level and make sure you have the 3mm needle valve (I imagine you do or it wouldn't hardly run at all). Might as well clean it realngood while doing all of that.

      Sounds good. I'll try to get to it this weekend. Thanks for your help.
