I own a 1986 Honda Interceptor that has an issue idling with the choke off. Is this due to the carbs being out of sync? I also know for a fact that it had been sitting for awhile and there could be rust in the tank. Has anyone put a inline fuel filter on their bike? This was my next thing. Also have a small tic coming from the engine. Not sure what that is all about but it seems to run.
