TOPIC:

I'm in the process of rebuilding my Mikuni BS 34 carburetor bank, and in the disassembly process I managed to damage the threads on the needle jet during the removal process, so the main jet will no longer thread into the needle jet.

I believe these are the stock carbs, Mikuni BS34's on a 1981 KZ 1000 LTD K1. I can't seem to find any information on the proper size of a stock needle jet, or where to find a replacement part. All I can pull off Partzilla is the stock part number 16009-1085

Would anybody be able to point me in the right direction as far as sizing, or where to purchase a new needle jet?

It is stamped on the jet.

Thanks for the help guys, I'm seeing 364 (a weird box symbol) Y-1 stamped on the jet (sorry I didn't notice this before, its microscopic and hard to see through tarnish). Does that part number make sense?

From a parts diagram, it looks like the Kawasaki OEM part number is 16009-1085. Steve, I did not see this listed on Jetsrus.com, but thank you for the lead!

Contact Mike there. He can find out for you.
