Yep, can't remember specifics, probably have it written down somewhere?
There is a lot of misinformation on VM modifications, much of it written by peole who don't understand how a carb works. You can make almost anything run and seem OK until you try something that is actually running properly.
I have several sets of VM's in various sizes (mostly for XS650's) the ones that 'work' all have emulsion tubes not 'primary choke'. I think I posted about it in 2009 or 2010? Photbucket has screwed everyone though so I'll re-do post when I get time and inclination.
Just spent some time getting software and did section of VM manual showing both types of needle jet.
Not quite the picture I wanted but OK
