Hello,
I am experiencing very weird issues with my vmax. I'll preface this with saying that I have new spark plugs, clean carburetors, properly synced fuel screws/carbs, and 120 psi of compression in three cylinders. My sled idles on three cylinders, seems to be fine there, when it gets warmed up it will bog around 4000 rpm and won't even engage the track because it won't exceed this engine speed. I have a video attached hopefully depicting exactly what I'm talking about. Out of frustration the other day, I took it to a shop and they are saying this could be a stator issue. I have no idea what the indicators of a bad stator are, hopefully someone could offer some insight there.
Another suspicion I have is that my needle valve assemblies may be bad in my carburetors. I rebuilt the carbs last fall and used a cheap rebuild kit. I suspect the seat may be bad as these are rubber, maybe my floats need to be tuned, I don't know. The sled ran perfect last year and now it doesn't. I took the carburetors off a few weeks ago and cleaned them out, this did nothing, it still bogged. I don't want to buy a stator if I don't need it, I'm a broke college student.
Any help would be so incredibly appreciated. Thank you.

PS: I've already looked into a potentially faulty throttle override switch. It's not that.
