You wont find anybody who can tell you what jets to use over the internet, maybe some can give you a rough starting point but thats all. Good luck with it.

If anywhere near Grantham Roy at RP Motorsport is excellent. Dyno, tons of knowledge and old school too.

I'm not near Lincolnshire. But I am 1 mile away from Frank Wrathall. So maybe I'll see if I can book it in with him.
But ultimately. All I want is the bike to be as pleasant as possible to ride, in its present form.

Frank is excellent and really knows his stuff. Tunes some of the fastest production bikes in the world.
Arch stanton:
Indeed he does.
At the moment the bike is on the bench of one of the best Honda mechanics there is. John Carr. Formerly of Bill Head Motorcycles.
Arch stanton:
The answer to my original question is..
130 mains & 1&1/2 turns of the air screw.
I don't have a standard K1 to compare it with. But it feels fine to me. Fine enough to go to the TT on anyway.
