2001 GPR won't go beyond ~4k rpm

[GpaaH]

Hello,

Bone stock ski runs smoothly to ~4k rpm, but not faster.

I can pump the throttle for a slight burst, but then back to ~4k rpm.

Any help would be appreciated!

Thanks, GPaaH

Powervalves operating properly? Check the fuel filter? Check the flapper at the end of the fuel pickup? Compression ok? Carbs ever been rebuilt?

Sorry for asking a dumb question, but - besides checking the servo motor - what should I look for?

Thanks for such a FAST response.

take the cables off the pully wheel on the back cylinder and see if it open/closes easily by hand

Do you think a clogged cat con could cause this?

Thanks!

Oh gosh, yes. Didn't even think of that because you're probably the only person left on the planet who still has the cat in there! Definitely check that.
