On a side note, I have been having a bugger of a time trying to figure out jetting for the VM30. I finally decided that the closest analog I can get is a CB450 with a dual VM30 setup. Similar displacement and (hopefully) power.
The standard VM30 jetting is a 250 main, 40 pilot, 2.0 Air, 6F5 Needle, and 159-P5 needle jet.
The VM30 "pre jetting" for the 450, per carb, is a 150 main, 50 pilot, 2.0 Air, 6F4 needle, and 159-P0 needle jet.
So, since I have a UFO for the slide which recommends a 50% reduction in pilot jet size, I am going to start with a 150 main, 25 pilot 6F4 needle and P0 needle jet on the way. I also have a couple of sizes up and down for the main and pilot on order, because I know better.
Hopefully between those parts, and the "standard" needle and needle jet, I will have enough to find a good combination for a VM30 with a ported head.
I also ordered a few main jets for the VM26 clone as well. Basically a 120-127.5. I figure that Silva's 1 1/2 up on the main is a good analog, so I ordered up to 2 full steps up just in case.
