Troubleshooting a V2K

[Jared]

I know that members here aren't too familiar with the Vulcan 2000, but this forum is better than any other Vulcan forum, so I figured I'd start here.

Tonight I went riding with some fellow Vulcan riders and one of them rides a beautiful V2K classic. While we were enjoying a meal he started picking my brain concerning some problems the bike has been having and one of the problem had me stumped. He actually let me take the bike for a spin to recreate the problem and sure enough as day I was able to create it multiple times.

In second gear, and seemingly only in second gear, at about 38mph (no tach) the bike misfires. It almost felt like it was just a single cylinder too. It doesn't stall. The bike keeps going, but it's quite noticeable when it happens. The bike actually jerks fairly hard when it happens.

If you accelerate slowly or shift early it doesn't happen.

Any ideas?
