not a stall out but just dont go no faster

well a friend of mine picked up a 90 kat 600. it does good on the idle part but he was telling me when he gets to a bout 90 even half throttle it starts to cut out or somthing.. it just dont have any more go.. its not hitting the rev limiter. and clues as to what might be making it do this?

Pod filters could... fuel levels in the bowls...

What has been done to resolve/verify the issue?

not so much that it cuts out, more like hitting a wall and sometimes surges of power like it wants to go faster, just can't. sorta like something is holding it back.

Most likely a jetting problem, I'm going to guess too rich. I'm sure it's not just in 6th gear but anytime you try to really open it up. When an engine is too lean, it usually takes off like a rocket ship - right before it melts a piston. You can probably get away with a smaller main jet and cleaning the plugs - they should be about black if it's that rich.

maybe a bad or wrong fuel filter??
