30/70 pulley combo
if you haven't done it yet...DO IT!
i've got a few thousand miles on this pulley set up now and i don't know how i rode with the stock set up.
i was on the highway today, cruising at about 70-75 and never once did i have to downshift to pass.
just yanked the throttle, the bike pulled from 70-90 without blinking, allowing me to just chill in 6th gear the whole time.

I did it with my 107" build. Not sure how my 6th would have been, but now ride in it all the time. Not sure how much my speedo is off though.
Anyone know how to set the TMAX to compensate? I see a 70T for pulley, but is there a setting for the front 30T?

I am wondering the same thing about the Tmax.

30/70 lands up being the same ratio (final drive 3.16:1) as a 30T engine sprocket and chain set from Evolution Industries which is easier to install and doesn't affect the speedo since it's before the tranny.

Doesn't that eliminate the compensator though?

I don't think I'd go that route ...read this thread:
