2004 ProX2 700

[dean d]

I need some help on my 2004 Polaris prox2 with the liberty 700. Im dropping a cylinder at rpms over 7800 rpm or so, Sled falls on its face takes a bit of feathing the throttle and it wakes up until you take it up to 7500-7800 again. We have gone through the carbs and exhaust valves and everything seems to check out unless were missing something? I'm willing to try anything at this point.

Thanks in advance!
