Buzz Killl?

Thanks for the tip, Josh. And for documenting your work, it is very helpful.
My idea was to find out the least I could do to get rid of the buzz, and just using the ex. cam on the intake side seemed do-able. The Guhl flash was incidental, I was wanting to do that anyway.
The idle issue is inconsistent, I hope to see whether or not fuel injector timing is even soon. I did hold it at 2500 rpm for a couple minutes and checked the head pipes with a pyrometer. It was within 5 degrees on 2,3, and 4, and between 5 and 10 degrees warmer on #1, so if it is lean it doesn't look bad enough to cause trouble and ran great on my ride today.
Will keep you posted on the cam situation
