I have a 83 xs650 with TCI and BS34 carbs and 26k miles. Bike sat for about 2 years until I bought it and rebuilt the carbs and put on pods, more open exhaust, and mikes green coil and wires. Now I'm trying to get it running and having some issues.
I went up to 137.5 on main and 45 pilot and set the mix screws to 2.75 turns out. Checked for air leaks with carb cleaner.
Set chain tension and valves.
Now here's where the weirdness comes in. The bike has trouble idling below 1500rpm even after manometer syncing the carbs. When I tried to use the dead cylinder method I had no trouble getting the right side to idle down to 400rpm or so, but the left doesn't want to go much below 1000 without stalling. The left plug is more black/oily while the right plug is almost clean.
Does this sound like an engine issue or a carb tuning issue?
