I see a fairly small flatline around 8200 RPM before the RPMs start to go up.

That there is yer stall speed. I would bump it up to 8500 then 8800 then 9100 and see if it has any effect on seat of the pants feel or lap times. If not back it off again and save some clutch lining.

RLV use to put out max rpm and clutch stall suggestions for their pipes. Might be worth a phone call.

I think 8800 is pretty much it for the new sportsman pipe then just concentrate on keeping the throttle open and the front wheels straight.
