John,
Thanks for the info! I didn't know there was a difference in the carb size. Its been 100+ these past couple of days so Ive stayed out of the garage. Probably rejet tomorrow. Hopefully, test it as well.
The tires are brand new although they are not balanced. Perhaps I should have been more specific. It feels like I'm riding a 883 or 1200C sportster.
If you have a ridden a non counter balanced twin for more than 45 miles without stopping you know what I mean.
Briny, I really think its engine vibration coming through the bars and some through the seat(bicycle rubber or spaces will be applied to the underseat after the tank is painted). Just buzziness through the handle bars. The bike idles great and sounds normal. I know its counterbalanced but after 20 minutes above 8k, your going to feel it. I do need to balance my tires though...
