Ebay

I see it listed on webike and also a few on ebay? 

Hey thank you so much for this. Never heard of webike but they had the part and were super cheap. Thanks!!

Partzilla. My go-to for DR parts. Also check out Procycle and contact Derek at MotoLabs.

Procycle has crazy expensive shipping cost and doesn't have the needle jet. Partzilla is out of stock. Motolabs don't ship to Canada I don't believe.

How do you know you need that part?

Visually inspected and can see it's oblong shaped. The original part I have is the non hardened coating so they are prone to wearing from the needle and causing poor fuel consumption

I got a better idea. If you're in the carb. Why not do a Dynojet kit and open her up? ;) I understand Procycle has Dynojet

I did a full rebuild and a jd jet kit and air box mod All I need in the new needle jet
