    Popping from one carb, bike only runs on full choke!

    I’d still suggest pulling the caps off the wires and the wires off the coil and looking at the copper inside the wires. Again visually mine looked fine but once I took them off the wires the copper was corroded and broken down. Are you idle mixture screws exposed? If they aren’t I suggest...

    My ‘80 Yamaha XS400 Special build thread..

    That’s a really trick setup you have there, I’ve only ever measured float height via a caliper with the float bowl off. My XT350 also recommends checking the float height like you’re showing so I’m gunna have to try it out.

    My ‘80 Yamaha XS400 Special build thread..

    My ‘80 Yamaha XS400 Special build thread..

    Hey y’all I figured I’d start a thread to keep track of the progress on this ‘80 XS400 Special I picked up not long ago. Friend of mine had this bike sitting around and he asked me to clean it up and sell it for him. After looking it over I decided I wanted to fix it up for myself instead. This...
