Your description make's Me think along the line's of a Fuel Issue.
Have you checked the fuel pickup line in the tank, (Filter clogging, water in the tank?)
Also check the TSS (Throttle Safety Switch) a bad TSS, or throttle bushing's can cause all kind's of Strange symptom's, and most people start thinking Stator right away.
I've heard of folk's putting 3-4 different stator's in the motor, only to find out Eventually that it was the TSS not being activated by the throttle pin because the bushing's were worn out.
There's a thread stickied at the top of the Arctic Cat sub forum, it's titled about ZL/ZR/ZRT bogging issue's, but actually pertain's to All Cat's since the introduction of the TSS.
It Could actually be something as simple as worn throttle bushing's.
