None of my current thumpers have a tach and only one previous thumper had a tach. So I have no idea what the red line is on any of my bikes much less whether I ride at, near or over it. I shift when the power drops off or it quits reving the way God meant for us to ride.
If you are worried about reving a little one lunger, don't. Run it like you stole it. Rebuild the top end when it gets tired. Then run it hard some more.
I know where redline is on my thumpers, it is quite easy to determine without a tach. It comes right before the waaah-bah-bah-bah-bah-bah-bah sound.
