Identifying JD Red or Blue needle for 450EXC-R

Recommended Posts

We bought this bike in which previous owners had installed a JD kit. The color of the needle in this carb is worn off. We are trying to determine which needle it is. It has seven grooves, and two shallow grooves below the seven, one 1/8 in. below and the other is 1/4 in. below. Is it a red or a blue? Help!

I don't know what the mini grooves are but difference between red & blue is in the OD of the needle before the start of the taper. My recolection is red is .1082" and blue more like .1074"
