I changed my air cleaner and exhaust. And have 3 CV carbs here. How can I tell which needle valves I have in which carb? I know at least one has been rejetted and the 88 sporty needle installed. I just don't remember which one. Is there a size difference or a number stamped on them?

 

The Sporty needle would be marked N65C. It's the one that has a straight taper from top to tip, no steps in the taper.

 

There are numbers on them just like jets.
