I just came into possession of a '08 vstar 650, it only had 1,000 miles on it but has been sitting in a... not so clean garage for the last three years. I had quite a bit of work done to it already (tank cleaned, carbs cleaned). I am still having the issue of both plugs firing but it is only running on the back cylinder. I swapped plugs and no change, the choke has no affect. I'm not the most experienced, and I'm at a loss. Google hasn't been any help.
