Bike runs great once warm and I open it up on the road, I just do short runs in the neighborhood due to the fact I have no air filtration, but idle and warmup is another story, choke makes the front cylinder pop, bang and blue flames, rear cyl runs strong and sounds healthy as can be, its almost like at idle I have just the rear cyl helping the limping front cylinder until I open the throttle. I think I either have valve issues, ignitor box issues, coil issues, or carb demons idk. I plan to get mcct, and doing the "relay mod?" I think its called. Also got some new ex manifold to header gaskets, smartparts baffles, and air filters otw. In short the bike rides great and pulls to 8k no problem, at idle I have a trumpet spumdimg right pipe the pops and bangs and a left that sounds great, carbs that puff back every so often durimg warm up with choke. Will keep an updated sitrep until this thing runs like a top.Thanks to any and all replies and suggestions.
