A quick search online say 20/73, but the chart is very old!

Might be worth pinging them an email if nobody gets back to you on here. Sorry I couldn't be of anymore help.

We ran 20/73 at Fulbeck a few months ago in Honda Cadet. It was cold. I suspect if it was warmer then we would have dropped a tooth

Also 19/75 is insane. That’s roughly the same as 20/79 which is waaaaay to big

22/73 any Better.

In Honda you will only ever use a 19 or 20 clutch sprocket.

As a rough guide a:
19/70 is the same as a 20/73.5.
19/71 is the same as a 20/74.5
Etc etc

Also we found that every tooth you go up on a sprocket. Ie 19/70 to 19/71 equals a gain of 200revs. The reverse counts aswell.
