Jets for Aisan carb 1975 2F FJ40

[Bubbalouie]

Hi all,
I have just moved to sea level and have been searching online for some new jets for my stock Aisan carb with no success. Just wondering if anyone knows where I could buy them?
Thank you!

Mikuni motorcycle jets - I bought some for my '71 FJ40 from Jets-R-Us just a few weeks ago. Type N100.604, they come In many different sizes.

Oh great! Thank you very much. I did look at the Mikuni jets online and wondered if they'd fit!

Not sure if you're aware, but there may also be a spare set of jets screwed into the back of the plugs. I found these on my 77 FJ45 carb after a local mechanic drilled the originals out when attempting a tuneup (epic fail).
I installed the spare jets and all was well again.

Ohhh that is very cool! I was not aware. I bought the Mikuni jets already but I’ll check for the spares too!

Hey, I wanted to jump in and ask, if I order the N100-604 jets that they are a direct fit into our Asian carbs?

Thanks,

These are just for the main circuits, not slow jets or power valve? @4Cruisers what carb/ jets are you running here in New Mexico?

Main jets are what I’m looking for.

Thanks,

@4Cruisers Thanks. Is that for an early 2F carb with an Auxiliary Accelerator Pump connected to manifold vac? Are these all Mikuni brand?

'71 F 2-bbl. carburetor, no AAP. I'll be installing the carburetor on the original 2F engine from my '76 FJ40, using the F intake manifold that's currently on the '76 2F in my '71 FJ40. The 2F in my '76 already has FJ60 electronic ignition with vacuum advance, and the F carburetor has already been ported for vacuum. Should be a decent set-up.
