+ on VM's

If they were VM's we could get you in the ballpark. No idea on the TM's
What did they come off of ?
Were they meant for an airhead ?
What jetting do they have right now ?

Come to think of it, I had a TM 38 on my Rotax powered Ninja 250 and it uses essentially the same brass that the VM series does.

So here goes:
These are the specs for VM38s on a '77 R100/7

Description Spec
Main Jet 210
Pilot Jet 25
Needle Jet 166 P-8
Jet Needle 6DH3
Slide Cut Away 2 This will likely be different since the TM is a flatslide
Main Air Jet 0.5
Needle Valve Ass'y 3.3

The other option is to call SUDCO and see if they have specs for what you got.
I made my own cables from the stock cables, take your time, measure three times before you cut anything.
