BTW I'm on at the top of the needle and still four-stroking the whole time, and yes, it's 191.9 Km, not 180.
How long can "China doll" hold at WOT? Also, high altitude (+gear reductions and "too lean?")

You are going to need a smaller jet then If that is the case.

Almost certainly. As you can see from my speedo, I can solder like a mad man (it's in my genes), but I don't have any minute drill bits.
Is it the NT or BoFeng carby you have???

BoFeng, 'member? I put a Viton ring.
Here is a link to get a bag of jets that will fit the BoFeng....Your carb comes stock with the #70 and these jets are sold in differences of 5s rather than 1s or 2s...Your next one to try from this jet kit would be the 65 to go leaner...At your altitude it may even be just right along with a proper needle valve adjustment to compensate for the leaner jet...lol.

I Know I need predator jets not the normal ones.

And I was thinking the same thing; 65 is normally too lean but might be perfect here...I hope.
If it is somehow too lean you can simply order a 68 Jet https://jetsrus.com/a_jets_by_carburetor_type/jets_keihin_99101-124_and_99101-ZF5_air.html
