If you have the removable breather jet you have post 04 carb.
I would think the manifold is the same year.

One on the left is a new one. Part#16-1658
OD is 1.890/ID is 1.790
One on the right is a old one. Part # on it is 367
OD is 1.815/ID is 1.625
The ID on the old one is the same size as the intake ports on a Evo head. Ran into this when I was looking for a S&S intake manifold for my Wood's CV carb. The S&S manifold for a CV, is the same size, as the new S&S for their S&S carbs. You have a 1.790 intake plenum going into a 1.625 intake port, which I don't like, but S&S said it wouldn't make any difference. And my tuner at the dyno proved that. The manifold on the right, was the one I was using when I was running a Super E. Oh, if you want to run a CV carb on a S&S intake manifold, you WILL have to use the larger carb to manifold seal, Part#16-0242 from S&S. hth
Ride Safe,
Harold

Good or bad idea?
To throw some carb cleaner in the gas tank? Can't figure out why occasionally my bike just doesn't wanna go. It's not the weather, humidity etc. Just once in a while it's not the normal warm-up and she spits and sputters something awful. I guess maybe bad gas is a possibility too? But doesn't make sense that for as good as it runs, on the rare occasion it does this, it's horrible. Any suggestions on what product/manufacturer might help as far as fuel additive? Could debris be breaking loose in the carb on these rare happenings?

Gotta take the bowl off tonight and check the float level.

Don't overthink it, use the correct parts and trust that the dudes who designed them know what they are doing.
The thinner S&S ones sit where they should, stuffing the H-D stock ones in there can cause warpage of the rubber and then it don't work so good.

Hello Mr. Spanners! I'm planning on pulling the carb and manifold tomorrow...........THC sent me the S&S gaskets, and, I agree, they are made the way the are for a reason.
