Yamaha xlt 800 wont turn but 6000 rpm (44mph)?

My 2001 Yamaha xlt won't turn but 6000 rpm and go 44 mph. shouldn't it be faster? If so what might be wrong with it?

If it was running okay in the past, you probably have either a plugged fuel filter, worn fuel pump diaphragm, or damaged power valve (in that sequence of liklihood).

Check your fuel filter and run a compression test. You should see at least 135 psi on the compression. If you do, I'd lean toward a carb rebuild. If you don't.....power valve.

Make sure your throttle cable is adjusted properly, you may also check your revlimiter adjustment.
