Another Lean Carb Question
After modifying my exhaust (1 1/2" hole saw) and removing the AIS I still had some backfiring on deceleration. After lots of reading on here and in the KB I figured I'd remove the carbs and drill out the brass plug so I could adjust the PMS. Anyway, I read something that said not to separate the carbs when I had them out and I don't plan on it but I discovered they were very loose not tightly held together. The two long bolts had backed out some. I see a gasket between the two carb bodies, is there some sort of balance tube between them or what is it? Since the carbs were loose, could this be the cause of it being lean? I put lock washers on the bolts and tightened everything back up. Front PMS was @ 1.5 turns out and rear was just a bit more than 2 turns out. I've set both @ 2.5 turns out to start. Waiting to put the carbs back on until I get some feedback on the loose issue.
BTW, this is on an '03 1100 Classic all stock except for the exhaust mod.
