Its cool im always happy for any input I can get. The weathers pretty nasty here in Michigan right now, and im waiting on a new thermostat housing to get here so I deffinetly have a bit of time to pull and clean the carbs. Im also going to pull my petcock, Ive had issues with it in the past.

Thanks

 

Weird idea: could be one of your butterfly valves not closing fully after you flick the throttle, and then slipping back into place. Check them when you have the carbs off. make sure your vacuum sync is OK as well.
