what does a new racing mikuni 44 sbn come with?

mcn6

Silver ones came with
140 main
120 pilot
14psi p/o

Black ones
125 main
100 pilot
15psi p/o

That's for the carbs with primer fitting (no choke plate).

MrSki

There are a few options for original jets that come in the carbs. The attached has them listed. You'll likely end up buying a bunch of jets anyways as this is a custom application.
