EX250 Dyno Chart
These were taken on June 4, 2002 at G-Force after they'd finished building my first motor. To give you an idea of how good this is, the motor was putting out about 17 horsepower and had an air/fuel mixture of about 18 when I brought it in.

Here is the dyno chart for the bike I campaigned my 2005 season on.
The moral is to check these kinds of things before you start racing.
