VM18 are pretty simple actually. they are super flexible to jetting. usually you don't have to touch any jets besides the main. Shes running a 65 or 70 main with .35mm thick carbon reeds on the block.
I def suggest it if you wanna pick up some nice grunt all around, but def make sure you get a matching intake and upgrade your reed block. stock M1 reed blocks are kinda a joke and if you run a 18mm intake into it, your fluids gonna hit a hard square wall
