The threads are M5 :D
Naraku M5 jets will fit and you can buy them in packs of 10 sizes, with 2 size between them. :)

Bigger wtf?! :O

When i bought the set #80-98 i was using #84 with an open cone filter with all other motor parts being standart. I still dont know how you guys get up past 100, without going very rich. Which engine modifications (filter, cylinder & exhaust) have you done and what kind of qlimate do you live in? :D

Maybe different fuel quality has a part in the jet difference. More Ethanol would need bigger jetting.

Here, all fuel (perhaps not diesel, dunno) are with either 5 or 10% ethanol, and i cant remember what it is. :)
But it is interesting, where do you guys who uses very large jets live? :D

Doesn't really make sense for me, as hot weather and high humidity (is 80% high?) would decrease the need for fuel, as there are less oxygen per liter of air. :p

It must be something with the fuel then, problably. :D
