Question regarding Mikuni Hex shaped jets as used in VM 34’s and 36’s.

Regarding the numbering and the jet size. From what I have read the number is related to the amount of water flow through the orifice over a given time and not the size of the orifice.

Is it correct to assume that a #360 will flow twice the amount of a #180 jet if all other things are equal?

Good question. I thought it was related to the orifice diameter but maybe not so ... at least, not always! Hopefully the attached will help. Check out the bottom of page 5.

Thanks Nighthog, that is the info I was after. I will need to do some testing but now I am on the right track.
