to increase acceleration, but decrease the top speed put a small one on the front and a bigger one on the rear

Re: Need help with Sprockets
On the top speed run i did last month, i got 136.9mph at the redline (dyno speed) but my speedo was reading just over 145. So mines out by around 8-10%. Assuming yours is about the same, between 120-125 sounds about right.

Re: Need help with Sprockets
To be honest, Dyno top speed runs are pointless. You've got to remember that on a Dyno the only acting resistance is the technicians body weight, rear wheel, and thats pretty much it. Theres no wind resistance, front tyre friction, road resistance etc etc. Probably 130 true speed if im lucky!
