Ok, I missed something.
Since I live in Florida, and hardly ever use the choke, I saved some money by buying a carburetor that had a choke switch, rather than choke by wire; a switch that was rather hard to reach when riding.

This carburetor has 3 settings.
Off, low and high choke.
Apparently I had turned on the choketo high, and then clicked it upwards; riding and tuning the bike in that setting; not knowing the choke wasn't in the 'off' setting, but in the low setting.

Now it all makes sense why the PZ30 performed lower than the 27.
My bike was tuned alright, with the choke on low.

In the off setting the bike couldn't idle well, and stalled often, and could only ride with up to 50% throttle, to 5k rpm.

Means both pilot (38) and main (108) will need to be increased, back to a 40 and 115 for starters.

So this weekend, I'll have to rejet it again, now with the choke to the 'off' position...

Kind of an embarrassing mistake...��
