Hey Easy Rider, Sinical, you out there? I'm the guy that had all charging problems last year and changed out the stator. I've talked to you guys before about deceleration backfire, popping and spit n' sputter. The carbs are the stock BSR37 Mikuni, I put Hypercharger intake, Cobra exhaust and a Dynatek 3000 ignition module. I put in new stock coils and BPR7ES spark plugs. Front carb jets are 125.0 main and 17.5 pilot, the rear has 122.5 main and 17.5 pilot. Bike starts and idles ok after it warms up, but if I bring rpm to 1500-2000, it spits n" sputters then smooth out a few seconds then stutters again, runs smooth, then spits n" sputters again. On the road when I slow down or have to come to a stop it backfires, not good! The last time I had this problem I was in a truck, it backfired and came to stop. The timing chain had jumped and bent all the valves! I've tried synchronizing the carbs, no change. One of you said this is a symptom of a lean condition, okaaa lean huh? Vacuum leak? Well I put new carb mounting boots in, figured their old, maybe cracked, no change. Bikes old but so am I, I hope I out last the bastard!
