2001 Kawasaki 900 STS - Hesitates at ~4500 RPMs
I'm having problems with my Kawasaki 900 STS. Acceleration is great and it starts as it should. However, once I get to cruising speed about about 4500 rpms it is almost as if a rev limiter kicks in and falls slightly below 4500 and then the throttle pushes it back above and it falls back down, etc...
I have a manual, but it doesn't seem to say that there is a rev limiter on this machine nor are there any warning lights on the dash. Does that make sense given the age/genre? I've seen some comments about checking for water flow through the water temp sensor and out the side of the machine. That appears to be fine as I disconnected the line and was able to easily blow air through. I've also checked my water temp sensor and heat temp sensor with a volt meter and both circuits appear to be staying open (showing a 1 on the volt meter).
Would bad spark plugs do this?

Try riding it with the seat off to see if the exhaust system is leaking into the hull.
If not, try loosening the fuel cap just a little and see if that helps. Could be a fuel venting problem, but I don't think you'd see it appear so quickly.
For grins, try running on Reserve.
