What size engine is the VM20 meant for?

Mikuni lists it for 70cc to 125cc minibikes. It is a 20mm round-slide, so it suits small four-strokes rather than larger displacement engines.

What jets does it come with?

It arrives with a #22.5 pilot jet and a #180 main jet installed. Most builds will still need jetting changes for their intake and exhaust.

The air filter side is 43mm OD. A 42mm filter will squeeze on, so measure your filter clamp before ordering.

A Honda-style throttle cable is recommended. The carburetor does not include a cable, so match one to your throttle housing.

It uses a flange mount with a 48–59mm range. Check your intake manifold spigot diameter against that before installing.

Yes, it is sold as a genuine Mikuni VM20, 273 series. That matters for jet interchangeability and replacement parts.
