Ran on the dyno this weekend and power seemed low

Hey all,

A local car/bike show this weekend were dyno testing cars and bikes, so I ran my gen 1 that I bought earlier this April, after a few pulls the highest numbers it put down was 123hp and 80tq. Does that seem kind of low to anyone? It has a pcIII and a hindle slip on exhaust. Since April I've replaced the radiator/fan, fuel pump, spark plugs/oil and valve cover gasket. It has 24k miles on it now, this is my first liter bike experience so I don't have any reference to what these bikes should feel like. Any ideas what could be the deal?

Thanks,
Larry

You pinch any of the fuel lines when putting the tank back on? definitely is low.

No pinched fuel lines, a compression test might be telling, not looking forward to getting to those 2 outside spark plugs though.

What where some of the other bikes/models pulling?

Where there other zx10's there pulling 165? ZX14's pulling 190?

Would be interesting if you did a pull somewhere else to compare before you go and thinking something is shot.
