    Quick carb question?

    I got my 200x to idle real good now, but as soon as you give it some throttle and let off it stays reved up in the lower RPMs for a minute?? Would this be it running too rich or too lean, and what would need to be adjusted to correct this?

    Hm, your right? I never thought of that. Its a pretty new motion pro twist throttle, but you can adjust them in a couple places. So ill check that out? I never would have guessed that could be the problem.

    My Bw does the same thing. I give it gas and then let it off and it will sound like it almost bogs down for a few seconds. I wouldn't use this as a sure sign for running "rich" or "lean", but in my experience it has always happened from running a little rich.

    oops...I reread you post and it sounds like are bikes are 180 degrees from each other. Yours revs up and mine boggs down. Maybe its running a lean then??? BTW I love your color scheme on your trike.
