ok here is a pic of the track i race on i'm doing about 41-43 second laps and the fast guys are doing about 36-38 second laps it's a very flowing track with a lot of wide open throttle and as you can see a big straight through the centre and i'm getting about 12-13 mins run time and thats with a hong nor 2080 pipe and this motor isn't a slouch either it also still has the extra shim in and running 1.0mm clutch springs with composite shoes...
