RPM hitting 6500 and staying there.

[blackcat09]

So here's the deal. I have a 2009 M8 153 with 1550 miles and bone stock. The problem is when I am at idle or moving slowly and I pin it, it seems to stick at 6500 RPM. Once you blip the throttle a few times it takes off and is good. It did it a few times while I was cruising at a decent speed but hasn't done after I cleaned the clutches. I took it to my dealer and they worked on it but nothing changed besides the weight of my wallet. They checked reeds, power valves, spark plugs and wires, they plugged it in and found a wiring issue to the servo and fixed that but I'm still having problems. I think it might be clutching but not sure exactly what. Running out of ideas and patience. Any help would be greatly appreciated.

Thanks

Clean and adjust the power valves. If it was clutching it most likely would not cure it self after you blip the throttle

Power valves have been done by myself and the dealer al ready. No change

Check your muffler maybe coming apart

If im not mistaken 6500 is where power valves open up.

Your clutches could be binding. Check bushings and rollers in secondary clutch.
