Question the guys tuned with the Bazzaz and PVC, if I drop a tooth on the front sprocket or two up on the rear do I have to retune the bike? I'm thinking no since engine rpm and throttle % openings will be the same....just difference on the wheel

no.

I bought some db killers for my Termi exhaust from a company in Germany.  The tube is wider (wide enough to fit the tube from the Termi db killers in it with room to spare) and shorter.  They are machined out of a single piece of aluminum and they sound great and very little popping, maybe just a bit when cold.  I get popping on decel with the Termi db killers removed (and it is just way too loud IMO), less popping with them in but not loud enough IMO.

Like all the others, my 1100 EVO popped precipitously when new, to the point that I complained about it at the 600 mile service. I left it alone and it mellowed-out over time, as the tech said it probably would.

9000 miles later, and I have absolutely no quarrel with how it runs.

Am I the only one here who's bike runs just fine in totally stock trim?
