Bike sat in my garage for 7 years after my Father couldn't ride any longer..I began the process of getting this vulcan 750 started again and realized the gas in the tank was sludged and after a long process of starting and idling with choke on it slowly sounded better and stayed idling longer each time. After bike ran more than 20 minutes started getting oil out my exhaust with smoke and back fires... Upon closer check and after oil change I noticed gas is in my oil, and lots of it. Any word on how to get this fixed or what is actually going on here? Could it be from clogged injectors?
