Freestyle Is this 48 or 46 novi

[NewName]

Hi
Got Double novis.
Their on Top 51 and bottom 48. but their is a 46-47 throttle Plate.
Are this 48 or 46 novis ?

 

[loictahiti]

Seems to be 46

i would guess 48. venturi size at the exit of the carb. i could be wrong though

Brand new Mikuni 46mm throttle plates are just a little bigger than 46 mm across but not 47mm, so.

dont know what they should have... but i think they are 46

46s have a step at the flange. 48s have been bored to 48, so there is no step left. one glance tells if they are 48s.

But why there is a 46 throttle Blade and no step in the flange?

Must be 46 then?

 

[TheBuzzard]

take a pic of the throat , right at the mounting flange.

46 Mikuni got this step.
Novis are tapered from 46 throttle blade to 48 flange

46 or 48 novis?

 

[TheBuzzard]

see how the one on the right is smooth with no step? that has to be a 48. the one on the left has a 1/4" step and has not been bored. if those are a dual setup, it looks like they are mismatched.

No, i just got 2x46 and 2x?? For picture.
Is it right that a 48mm novi has A 46 throttle Blade?
