So I just cleaned the carbs on my 86 1100 and rejetted it using the dynojet kit and got it running. I got it running and it ran like crap. Would not start without ether and when it was running it ran like crap. It would rev all the way to 10 grand but on deceleration it backfired. When cold the throttle response was bad but it was better when it was warm. The worst was off idle. So I bought new plugs and when I pulled them the center 2 plugs were white and the outside 2 were black. So why were the outside so much richer than the inside which were really lean? I called my friend in Mass who has worked with these bikes and he said syncing the carbs. The only other possible thing that I can think of is valve adjustment. What do you guys think?
