Top one is not a real VM22. It's so called "genuine VM22" by many pit bike parts suppliers. Bottom one is a real VM22 which you can find on mikuni website. I have to admit that chinese made a very good carb for money and even use genuine mikuni jets. It works very well. I just bought one myself.
You need 17.5 pilot and 107.5 to 112.5 main depending on your 125 engine setup.

ok thanks not sure whats in as standard what it came with, needed a new one anyway my old one had parts of the slide etc missing and was really clogged up its a standard 125 engine with an fmf 4.1 exhaust at present but its being sold so will have a standard exhaust on as the bore on the outside pipe of this exhaust is about 45mm lol

ok i got the 17.5 pilot and 112.5 main now its running on idle with choke off fine and revving fine but exhaust getting very hot, the needle is fully up and iirc its about 1 turn out on the mixture any ideas?
