Polaris 90 sputtering

[dropmar]

The polaris is cutting out at full throttle. I have a FMF pipe on it and have a 120 main jet in. Seems like it started running rough after my son swamped it out.
I took the carb apart, checked the jets and it still runs bad at top speed. Do these have rev limiters?

Hello, I think these have a rpm limiter on the cdi box it has phillips head bolts with a piece of metal between it on the outside of the box, Dewayne
