What RPM should my ZR 900 be topping out at? I believe it should be around 7500 but I'm not sure. I put the OVS/RKT kit on this year and on the one high speed run that I have been able to get in this year and my RPM would spike to 7000 at WOT and creep to 7100 after a long pull (1/2 mile) Just wondering if anybody has any thoughts/info or experience with this kit and what I should/could do to get my RPM's up.

If its all stock, let it pull to 7200 the slowly creep up to 73-7400 rpm. Your tach is a little off on the top side too .

So I am closer then I thought...thought I should be at 7500.
