Carburetor size
 

How do I tell what model and size Mikuni carburetor I have?(ex. TM, vm, Tmx) It say kyogb in bottom of float bowl and I looked it up and there's a bunch of different models of that code.

Normally you'd measure across the outlet bore of the carburetor on the engine side to ID the size. Take a picture and post it here to get help with the actual type of Mikuni it is.
