Power problem revisited (with audio!)

[VTXorcist]

Thanks for the add'l info guys! Just so you know, I put 'er back together and wasn't able to get the seal on the exhaust that I had before, where I sheared off the bolt. I'm nervous about riding with exhaust visibly leaking right at the cylinder head, so I haven't really done anything with it since Saturday. Guess I need to fix problem A before I move on to problem B.

I had just replaced the spark plug a few weeks ago, but since it's cheap, I'll try another plug and also double-check the gap on this one. I won't be able to give a report on the Chevron (got it already, but that's OK; can't hurt) until I get the exhaust fixed and get a chance to ride it for a while.
