Thanks to a friend I got both from Sudco.
The original specs were close but needed a bit of help. They called for 17.5 pilots, not even close since the engine would only idle with the airscrews seated. I then tried 22.5 which brought the airscrew setting to 1/2 a turn out and now I'm running 25s with the airscrew right at one turn out. I could probably go to 30 since the plug body is clean with no carbon whatsoever around the perimeter.
The mainjet spec was 200 and the engine would gain power/rpm if I closed the throttle a touch. Made me think rich, so I tried 190s and it got worse. Went to 210s and I'm a happy man with a happy engine.
The rest of the specs seem to be right on the money. I'll ride for a week and see what happens. So far the plugs are burning very clean with just a hint of color at the tip and no detonation.

I meant jet numbers or specs. Who's specs? Just curious.

I just reread your post and realized you got the specs from Sudco. They recommend jets for different model bikes? I did not know that! Is it somewhere in there manual?

They'll give you a rough starting point. They stay well to the rich side to be safe.

I don't know if they have different specs for different bikes. As you can see from my previous post they were close but did need a bit of work.
