I forget who compiled the data and posted this, but all credit goes to him:

The chart is for a 750, with and without the Herzogs in the gearbox. If you go up to 3,000rpm, 4,000rpm, etc and then follow across, you'll see the shift points. Depends on how much you want to wind it out.

Like a lot of folks I find the 3rd/4th shift problematic. Mine will run just fine in 3rd up to 55 or 60, but feels like I should shift into 4th at around 50. When I do, I'm usually sorry, as 4th just doesn't have the pulling power. Any wind or a small hill and I'm back to 3rd again.

I am with you ! Shifting into 4th on anything short of fairly flat is unproductive. The way my herzog geared bike is set up it will not pull 4th clean until 55 indicated. I think 4th could be a little lower geared which would limit your top speed thart you can't pull anyway! :roll:

It depends on the terrain. I shift to 4th around 50-52, but on hills 3rd will wind out to about 60-61 then the valves float and I don't go any faster. I think the valves float...it's pretty noisy at 60mph in third gear!

I wonder who the guy was that had to get the test chart results by putting the rig in reverse and winding it out to 6400rpms?!? :o :shock: ...that must have been, uh, exciting! :lol:

That's a very interesting chart. I shift by sound, and the chart agrees with what I consider the approximate speeds I see when I shift, which apparently is right at 4000 rpm.

After reading the posts, I tried moving my shift point up by 5mph. Boy, it did make a difference. I think I was babying Erika. It may be my imagination, but I think the bike is even running better.

Anyway, thanks for the conversation and expanding my knowledge.

No joke. She is most definitely running better for you. Keep it up and enjoy.
