OEM setup takes two gaskets swished between an aluminum plate...not sure if this is used for AM reeds. But, I sent two just in case.

Threads are a perfect match but the point looks longer and different taper. They do thread in perfectly though and "seem" like they would work.
Are these the same ones you're used to seeing?

Those won't work... the taper is different and the stepped shoulder is different. Pretty sure that's exactly what @JetManiac was talking about. You're metering a very tiny passageway with that needle, if the tapers don't match it will either flood it with fuel or worse, not let enough through.
(EDIT) And possibly ruin the seat if you turn the wrong needle in too tightly.

Yes, those are the same ones we stock, made by JetWorks. They are for 04-up SJ's with dual 38s and the length and shape of all the front profiles are different so we have never used them in oem dual 44 application.

I've started using the extreme throttle adjuster knobs on oem needles. They're easier to adjust than T handles.

Well, thanks guys for the heads up. I appreciate that, I am sure I would have been fighting with them without knowing that. Much appreciated.
@hornedogg79 -- Can you link me to these extreme throttle adjusters? I definitely need something for adjusting.

Thanks man. So you like these pretty well? Easy to use?
Are there any other options out there?

Decided to add some quick disconnect to my stator wiring. I talked to a couple people who said they did it, and I don't see any real reason not to.
Flywheel installed.

As it states on our site, these are for 04-up SJ. 38mm carbs. These will NOT work in your stock 44mm OE carbs.

John, I never saw that warning on your website and I just checked, still don't see it. Navigated to Watcon.com > Fuel System > Carb Adjusters > LOW speed with tbar
Description on your site:
These are needed when you are moding your SJ, as the original screws are behind a brass plug, and cannot be accesed for adjusting with the carbs on.
Added to cart and purchased. Never saw anything about 38mm only.
I just did it again to be sure, and here is the link:
https://www.watcon.com/fuel-system/...screw-yamaha-sj-04-later-low-speed-with-t-bar
EDIT: received an email from John, I was not aware that 38mm carbs were the only option on 04-up Superjets so while the site doesn't say 38mm only, it does say 04-up so my mistake.
It is not a big deal as the group here caught it for me before I was struggling with it later.
Guess I will have a set of tbars to sell that are installed but never used....lol.

John, we will chalk it up to a "learning experience" which I have had plenty lately.

The Epoxy that was in my intake didn't survive the powdercoating heat, so had to redo. I came up with using some foam in the runner, then filled it up, let it cure, and then sanded it flat. I had to burn off a little of the left over foam, and then scrape it all clean, but came out pretty cherry I think.
Spent about 30 mins putting on the exhaust manifold, starter, bendix, stator, and flywheel this weekend. Looks pretty good with my powder coated parts and the Jetmaniac stainless hardware kit to match all the hardware Holeshot put on the motor. I am digging the black and blue contrast. Please excuse the mess.

Testing pop-off tonight, and it appears my needle and seats are leaking, and only popped at 18psi. So going to order a rebuild kit for each, and do a complete rebuild.
These were supposed to be on a fresh rebuild, but I guess I better be safe.

What were they supposed to pop off at?
And did you soak the needles in wd40 or similar before checking pop off?

Yessir. I think it's supposed to be 22psi but I'll have to ask Holeshot. I think the issue with the popoff is I have a 2.0 N/S and so the 65g spring was for 1.5 N/S

Your project is looking good.
The extreme adjusters are definatly worth checking out, I am very happy with mine.
What is the deal with epoxy on the intake manifold? I tried researching it but couldn't find anything

Any chance you could link me to this? That looks really nice.
