Went for a group ride today and all was fine with the bike until after lunch. Went to start it and idle was low and stumbling, acceleration was not smooth and jerky with flat spots.
Got it home and removed the plastic. Fuel valve OK, pump pressure and flow good. Both carbs for sure running lean with no noticeable vacuum leaks. I found this screw on the top of the engine by no. 5 cylinder. It wasn't there when I changed the oil a few weeks ago. I have run out of time today for any more work. I suspect it might be part of the problem, any one guess where it goes?
