Looking for some needle jets

[Farmer Fred]

These seem to be unobtainium, but it might be worth a shot.

I am trying to find a set of (4) type 258 needle jets for Mikuni VM carbs, size 0-5 and/or 0-3. They were OEM in Kawasaki and Suzuki 4-cylinder models in the late 70s. I would consider buying a bank of carbs if they had the right jets.

These sizes were never available from Mikuni, and now they are discontinued by Suzuki and Kawasaki.

Thanks !

Fred, I may try and get some of these from Keyster in Japan - the only issue is ordering 100 of them at a time - so if I can get a few advance orders it would help. I just received a set of needle jets for the early Z1 carbs and they work well, so I may expand and go for some of the more popular ones like these. They're a little expensive - as they were specially made for us - the likely cost would be in the $5-$6 each range each (although far cheaper than the Kawasaki price of $20 each...). We might need to get the matching needle to create a usable pair as this series was installed with a few variants in size.

How much of a hurry are you in? It would likely take a minimum of 2 months to get them.

Is this what you are looking for? They are off a set of VM28SS carbs, GS1000S

Try (motorcyclecarbs.com) they had pilot jets for gs1000g and they are very helpful.

Hi Jeff,

Don't sweat it right now. I will try another combination using the 0-6s and see how that turns out.

Triker Bob, no one has these needle jets, it seems.

Yep. The needle jet sits on top of the part you have in the attached photograph.

It reads "258 0-4" is it of use?

You can actually still buy 0-4s. I bought a set from SUDCO. But the O-3s and 0-5s were OEM only, and now are discontinued. I have a set of 0-6s and a set of 5CN8 needles I am going to try.

Fred, let me know how it works out - if those needles don't work, I probably have some spare 5DL31's - they are the needles used in a handful of KZ1000's and all the 29mm Mikuni smoothbores - nice manageable taper on them

I have a set of 5DL31s too. Got em from some Brit in NY state! But the generally were matched with the 0-5 needle jets, which I don't have. The 0-6/5CN8 combination was in the 77 KZ1000 (non-LTD).
