There are some Mikuni photos and links to more info in the Which Carburetor? article.

Nissan Competition used to carry all the jets and other parts.

anyone, got any info........?

I run dual mikunis on my race car with an a12, 32mm chokes 155main and 180 air and 65 pilots. Set up depends on engine build up for street 1200 I would start with 28mm chokes 135 main 180 air and 55 pilots all depends on comppression, head work and cam being used and size of engine
on Ebay their is a service maual for sale although it is in the USAe-bay mikuni manual
