Gary,

This works well for VM-28
VM-28  Slide #2.5, Main Jet #155, Pilot Jet #45, Needle Jet 169N8, Jet Needle 5F21

I also have this written down for VM-26 (but don't specifically recall when I used it)
Main Jet #160
Pilot Jet #60
Needle Jet 182N8
Jet Needle 5F21
Slide #2

Thanks,

Kevin

Hi Gary,
I run a 26mm Mikuni on one of my Six Day riders. Starts, idles and runs very clean. I use a 190 main jet and run the needle one notch to the lean as most of our riding out this way is at altitude. Otherwise the setup is as Kevin has outlined for the 28mm.
Hope this helps - Cal
