I am putting my modified carb back to stock. I have the 148 Main Jet, the Jet Needle N31R & the Pilot Jet #40. I have tried to get Needle Jet #6 without any success. Two Kawasaki dealers I called could not find it on their microfiche. It's like they have never heard of it. They keep trying to give me the N31R Jet Needle. Anyone know where I can get this? It's in the KLR 650 Service Manual supplement.
