Welcome to the site Joe!
The adjustment on the secondary is to adjust belt deflection. If you want to raise your top RPM's, then you need to move the clickers on the primary clutch to the next highest number. If it is still set at stock settings, it will currently be set on 3. If you move that to setting 4, you should be right at 8K.
