389 THROTTLE NEEDLE D TYPE
Amal 389 series D-taper throttle needle for carburetor slides, also listed as RK9-063.
This is the 389 series throttle needle in D taper, an Amal carburetor internal that sits in the slide and meters fuel as you roll the throttle open. The needle position and taper shape how the carb responds through the low and mid throttle range, which is why Amal offers several taper letters for the same needle family.

We don't have a lot of catalog history logged on this specific part number, so we can't point you to a specific model or year range from our records. If you're matching this to an existing carb or parts list, check the needle you're pulling out against this one before ordering, since Amal needles look similar but the taper stamp is what matters.
It also shows up under the alternate number RK9-063 if that's what's printed in your parts book or on an old invoice. Call the shop if you want us to confirm it against your carb before you buy.
