After looking at several pictures, I thought the needles that came in my carbs were Factory Pro. Just wondering what you guys think?

In the picture below, I have the believed Factory Pro needle (top) and a known Dyno Jet needle (bottom).
I can take close up pictures. I can also mic the length if needed.

 

You are right! The top is Factory Pro.

 

Thank you for the answer! I appreciate it.

 

The bottom needle is a Dynojet. Factory Pro needles have 5 grooves, Dynojet has 6.

 

Wow. Those tapers are a lot different. Depending on the slide spring stiffness, the Factory Pro needles look like they flow more everywhere.
