hey flrider, I have M1's on my bike, they are great! Changed from 208s and the M1s are a bit easier to lay over in the turns. They also seem to hold the power pretty good so far.
I know Juggler has a spedohealer, and he's wired it up to show the last max speed....pretty cool stuff. He's running the 16/40 so he might be able to help you guys with some of those questions.
