Mikuni Jet size conversion??

Does anyone out there have a conversion factor for the jet sizes?
I have a #380 and I need a #420. How many thousandths of an inch is a #420?
Thanks!!

I feel for ya brotha, I have been in the same boat. You would think the code would be hacked by now. Good luck.

Just move the decimal point two places.
A 380 jet, is 3.80mm.
A 420 jet is 4.20mm.
Multiply the 3.8 by .03937 (the conversion of metric to inch) and you get .1496"
multiply the 4.2 by .03937 and you get .1653"
a difference of .0157", almost 1/64 of an inch.
