I have been aware of the WOT recommendations to reduce oil consumption and I find myslef relieving my tensions quite a few time a day. Should I be concerned about running it to the top of the tach or should I just let it go? Is there a limiter at the top end to cap off the RPM's before they go over the red line? I know there is a limit to the RPM's if just reving it up in neutral. At about 4000 RPM's it begins to cut back on its own. I have not yet just let it go to the top in concern for over rev damage. Any suggestions? Any idea what the top end is on this Northstar for RPM and speed?
