Hey Rev, you might want to go to VROC.com and talk to the helpful people in the "tech" chat room. I Put slashcut Cobra's and a tuner on my Vulcan 1600 and didn't have any luck keeping the backfires and stallouts at the light at bay until I talked to these guys. It sounds like you have a pretty good set-up right now and the only way to fine it up some more would be to take it in to a specialist to have it Dino'ed. I finally did that with mine and now it sounds like a friggin race car. In reality though, you really don't have to worry much about these Vulcans, they are practically fool proof and indestructable. Just think, at least your bike doesn't need a magnetic rear wheel like most Harleys to pick up the fallen pieces on the highway...:) Welcome to the Vulcan Club, glad to have ya'!:) We need more women riders out here.
