So good news and bad news... good news is that my jets arrived! Bad news is they ain't the right jets. I ordered both Mikuni and Keihin so I'd have a good stock, and the pilots are all too big. They are the same, just bigger. It said they fit the VM, TM, and TMX carbs, and mine is supposedly a clone of the VM22...
Thankfully I have a new carb arriving tomorrow, so I can swap the whole thing over. But I would still like to get the old carb fixed up so I can use it down the road.
I found the attached pic online, and comparing my jet, it does not have that flared seat at the base of the jet, and also has the extended brass tube on the top. Visually, I'd say mine is a CR/YZ style. The VM28 is also close, but it's missing the chamfer cut on the top of the threads, and the narrow section looks slightly smaller.
Unfortunately I buggered up the jet pretty good, so I can't take any accurate measurements.
I'd love to get your $0.02 before I keep shopping!
Many thanks.
EDIT: Looking at another pic, the jet for the VM28 looks to be pretty close.
