Mikuni Adjusting T Screws

[JKMike]

Hey yaw,

I just finished rebuilding my Mikuni 38's and am in the process of dialing them in. I want to get a set of the T handle high and low speed jet adjustment screws and I am looking for some recommendations on which ones to go with. I know the general rule is to stick with OEM Mikuni parts, but I really like the extended T handle on the aftermarket options like the Blowsion or Jet works sets. However, I recall seeing a few threads where people had issues with using these aftermarket adjusters. What do yaw recommend? Is there a top choice for the aftermarket ones and any that I should stay away from?

Thanks,
Mike

Which year and model are your dual 38s from?

They are from a 1996 Superjet.

The JetWorks adjusters (Blowsion sells the JetWorks) are designed for 04-19 SJ. They have extended handles to fit the longer recess on the newer carbs, that are not needed on your carbs. The high speed adjuster will fit your carbs but the low speed is finer threads and will not fit your carbs.

We have Mikuni oem T handles for your high speed adjusters and ez adjust caps for your low speed adjusters.

Good to know on the jetworks kit. So what about the Mikuni 38/477 low speed tee handle adjuster? That should work on my carbs right?

Those are incorrect.

Those are incorrect.

Which ones are incorrect? The jetworks ones or the mikuni ones?

That's a better idea, I just epoxied in a washer with a grove cut in it.
