ok, upon having a fantasic running commando now, I put a carbtune to the carbs and discovered almost no vacuum to the left carb and good healthy, normal vacuum to the right carb. Adjusting the slide screw or air screw has no affect on the left carb and the slightest tweak on the right side has a lot of effect on the right carb. The bike really runs great with no popping, missing, accelerates great, holds steady at any throttle opening without missing a beat. The carbs literally have evrey part new in them, sleeved, idle passages drilled out and set screw put in where blank was, new needles, jets, floats gaskets, everything replaced. New cables routed, carbs set up properly, double checked by a 30 year mechanic. I switched the carbtune hoses around and the readings followed the carbs. Any area other than carbs that could cause this and still allow the bike to run so well? Secondly running it this way surely cannot be good for the motor can it? I just thought it kind of odd that it runs so well and there seems to be such a difference in the carb balance. A mystery I'd like to solve for sure. Maybe I missed something simple and just am not seeing it.
