main jets BS34 the same as VM series??

Simple question:are themain jets of the mikuni BS34 the same as the standard kz900 VM series??

The type of jet is the same but sizes are different.

Thanks WG!
You mean a VM 100 is not the same as a BS 100?? or is the tread different
is there a calculation to use the VM's in the BS series?

Those round jets with the screw driver slot are Mikuni type N100/604 and they are totally interchangeable between the various Mikunis that use that style of main jet.
To expand on what George posted, they are available in sizes from as small as #50 up to as large as at least #170. They come in half sizes all the way through the range
e.g. 50 52.5 55 57.5 60 etc etc
This makes your tuning very accurate....if you know what you're doing.

PS: the N100/604 type jets are called the "reverse" style because the calibration direction is the reverse of what it is in the 4/042 style jet (Amal-style or long hex style) used in older Mikunis.
I'm just FULL of useless Mikuni trivia like that.

exactly the same.

A VM series N100/604 in size #100 is the same as a BS series N100/604 in size #100.
