hey
i bought some jets from jetsrus.com for my Ag 50 because I installed a bbk
I measured the original 80 jet and the 82 jet that was installed and neither were 0.80mm or 0.82mm, to my surprise they were each about 0.05mm smaller than indicated.
the jets i bought, 88, 90, 92 and 95 were all spot on, 0.88mm-0.95mm.
i did some reading and found not all jets are alike, just a warning to you all, different brands use different measurements for the same number. the moral is buy all your jets in the same place.
