    VM carb chart

    My search skills suck

    Anyone have that chart that shows the function of a VM carb by throttle opening?

    Much appreciated

    What kind of Mikuni do you have? You may not know it, but not all Mikuni carbs are the same. That 24mm Mikuni that needs replacing on your 2005 Yamaha TTR125 isn't exactly the same as the VM24...


    Actually the vintage biker one is very detailed about whole carb tuning

        Thanks guys, those are good links, but still not what I'm looking for.

        It's a 2 axis graph with throttle opening vs idle/cutaway/needle/main

        I'm trying to work with people with zero knowledge

            My 1st 2 links have a picture of a carb with markings where the slide sits and what jets are used when the slides are open that far. Cant get any simpler than that.

              Yeah, I was looking for that in a version that looks like a dyno readout. It's been posted here before. I am saving that one

                As an experienced instructor, that one's a bit too complicated for my purposes. I'll be dealing with millenials and younger.
