I added a Marks 4-2 exhaust with the 14" cans and had my bike dyno'ed to see what adjustments need to be made. The dyno chart shows me very lean at idle then rich from about 2K all the way to red line. My A/F ratio from 2K up is around 12-1
I would have thought a better breathing exhaust would have gone in the other direction and made the bike lean.
When I am riding I get a backfire sound out of the cans. Some I can barely hear and others are louder but not real loud. This happens as I am just cruising down the road at a steady speed and happens more when it is cooler outside.
