VM30 carbs

[SUPERTUNE]

TM34's baseline on my stg 1 or stg 2 RD400's:
37.5 pilot = 2 turns
310 main
389-QO / no airjet
#1 needle clip most of the time, but you can try #2.
Stock 4.0 slide
YZ85 VF reed cages/ UPP manifolds/ TSR-Barlow boost bottle/ Uni pods

to Lyns point & play devils advocate:

remember, rz350s stock come with 26mm carbs. Just food for thought. 

Throwing in the monkey wrench lol.

What about "Small Body" (Snowmobile) VM30 carbs? They should be easier to fit, and should most likely flow better than regular VM30 (which share body with the larger VM32 and 34 carbs)
I think Polaris Indy 340or 400 had VM30.

thats the same as a stock h2 carb, basically, which -will- fit in the stock intakes and arobox boots, so that is a plus. I have used those on an rd build btw.
However, the larger body ones have a bigger bellmouth and basically a velocity stack built in by comparison. I went from a small body 34 to a large body 34and i had to jet up a hair. and i used the exact same jet tube and needle and pilot to start.
