I get 3500 rpm's at 60 mph. Hope this helps.

In case you want a tach, I have a stock style one for sale, and I also have the sending unit and cable. Email me at bamf_shadow@yahoo.com if interested.

65mph on mine sounds a bit high in the revs but thats just my feelings , old iron wasn't ment to run highways at 65 really , I mean they can do it its just that they were made in an era of 55 so the final drive sproket was a bit small so I put in the biggest one I could fit and that helped a bit (maybe 500 r's)

If your gearing is stock, I believe your ratio is lower. You might be closer to 4000 rpm's at 60 mph, but I might be mistaken.

I've been at this for over 30 yrs and haven't had a tach on any of my HDs. Can't say I miss it. Don't know any better I guess.
