Look at the parts lists. The ratios are all listed. By 'Overdrive' I mean that the output shaft is actually spinning below crank speed. Most gearboxes in bikes have a ratio of close to one to one in top gear. The oddity with your box is that it's actually spinning slower than the crank.

Huh? I know. I calculated the approximate speeds when we decided to do this.

I'm not saying it's incorrect. I was just pointing out what I understand 'Overdrive' to mean.
Anyway, does such pedantry matter if it works as you wish?

GRiSO 5th = 0.9677 Norge 5th = 0.9355
As you can see, there's only a 3% difference. Which, oddly enough equals the difference in speed at 5K. Mathematics! [You must be registered and logged in to see this image.]

220 miles in Wales 2ºc to 8ºc - then back down again OK UK in January - who wants to be here?
But look at these pictures from Mid Wales (latitude 52º N)

Put my highway pegs back on. Did you know that with the Arrow headers and midpipe, plus a Mistral Hi-Pipe, you can remove the entire exhaust in one piece? 🧐

Mark, do you have any pics of how you installed your highway pegs? I have toyed with the idea of some additional pegs, but getting them symmetrically placed on both sides of the bike is a little challenging

It has been standing in the shed a long time and was all sticky.
