Summit 800X 2007 problems on full throttle and over 6000RPM

[atli]

I need help on my summit 800x 2007.
Sometimes when I go full throttle the sled starts to choke, also when I get over 6000RPM in slow throttling towards full throttle, sometimes the sled is ok and I have also tried different ECU.
I have cleaned the carbs, exhost valves, new sparks, opened the tank and gas pump and all of these are ok.
Dose any one have an idea?

Check valve in the hose to Rave valve solenoid sticking or not working or Solenoid / wiring. Do you get any lights flashing?
Better off to just block off all the hoses & bypass of all that crap and run off spring pressure alone if you know a mechanic who can do some work for you..

No flassing lights
I will check the valve´s and fix reve valve´s in full open position to test.
Thanks for the input.
