I'm guessing at the RPM as I don't look at it much, I listen to my engine.maybe it's between 5500 and 6000. I'll pay more attention next time and see. I think the tach needle is around straight up at 80 mph. I was looking at a pic that shows my tach trying to see what RPM that would be.

I learned all I need to know about life by killing smart people and eating their brains.
