    Carb flooding

    Im still waiting on some parts to service the jets and replace the bowl gasket, however I still have a serious flow out of both carbs when I connect fuel.

    Carb issues

    i recently picked up an 82 xs400 that hadn’t been run in over a year. I got it running, got rid of the bad gas, and cleaned the carb. Even after cleaning the carb, the left side carb is still flooding causing it to hesitate and leak gas out of the air intake. Any suggestion?

    Idle too Damn High

    So finally got my bike up and running and after riding it around for a while I noticed that when I come to a stop it likes to idle at around 2500-3000 rpm. I would adjust the idle screw but then she wouldn't idle at startup (to which she sits at a nice 800-1000 rpm). Should I adjust the idle...

    Carbs settings with short straight pipe

    I previously bought this bike as is somewhat running but cannot figure out why it won't stay running. To the best of my knowledge the last owner put a straight pipe on it and never changed anything with the carbs. So my question is since it is running pretty lean and cuts out after awhile, do I...
