Try it with the stock jet first. My cimatti came with a 14/12 with a 54 main jet. If you have to rejet, it'll probably be one or two sizes up or down.

As Dillon said, make sure it fits your intake. There are dozens of minarelli intakes and carb shims.

V1's made three different cylinders with different sized intake ports that limit the speed. I believe they are 20mph, 25mph, and 30. The cylinders look identical, only the intake port is different where the manifold mounts.

If you have a 14/9 carb, you probably have the 20mph version. I think the 25mph had a 14/12, and the 30 had a 14/14, and they had matching intake manifolds for each one. In simple terms, the intake manifolds have bigger holes to match the cylinder and are larger where the carb mounts for each step up in speed.

So putting a 14/12 on a 14/9 manifold and cylinder won't do much unless you port the cylinder and get the correct manifold, or port it to match.

This isn't always true. I've seen larger manifolds on smaller cylinders, and vice versa.

Don't open the holes in the airbox until you know it needs more air. SHA carbs are really finicky when it comes to airflow, and just randomly punching holes in it could throw it all out of whack.
