Well, you got to 75 mph before I did. But our 60 mph RPM is the same.

Well if it will go 90 MPH that engine will be screaming.:dontknow:

Yes, the more throttle the higher the RPM but the clutch will never allow the engine to over rev. So, if max RPM is 7500(for example....I don't know what is) The clutch will never allow the engine to rev higher than that. However if you punch it at 30mph the engine might rev to 7000 RPM to bring you to 60 quick. If you back off the throttle the revs drop but you will still be able to maintain 60 at the lower rev. While its true the engine will be at max RPM at max speed its also true the engine can rev to max RPM at lower speeds. Similar to holding a lower gear longer in the semi auto or manual trans.

I had one to 90 mph indicated on the speedometer. I'm don't know what the rpm's were as it's hard to determine without holding the throttle steady and when I noticed the 90mph I backed off. I can tell you it was really raving.
