What are the differences between standard Mikuni and Nismo Mikuni carburetors?

 

Copied from another thread.

 

"Nismo" Mikuni / Solex 44 (Type 5).

 

These tend to be known as Nismo colloquially because they were offered through Nismo catalogs in the late 70s, early 80s in North American markets.

 

They have the externally adjustable float with the provision for it to be mounted on either side (dual fuel feed lid), unlike regular s5's.

They also came with larger outer venturis too.
