So I got the carb back together. This was the result.
Motor runs hot. Header is cherry red. Idles beautifully though. It was a little high and I couldn’t get the bike to settle down consistently.
I wonder why.
Disconnecting the throttle cables made the idle settle down. Running the idle air screw all the way tight and then working it out seems to have fixed the overheating issue. I had too much fuel it seems. I feel better now.
