Default Changes needed for full V&H system?

Pre 600 here.

A while back I picked up a good used full 4-1 Vance & Hines SS2-R system that came off a Pre 600. Before installing this I'm wondering what changes are needed to run acceptably vs required to run its best.


From my reading, need might be:

Pilot jet screws out to 3-3.5 turns and shim the needle up with a #4 brass washer.


Required to run its best:

Fuel mix screws out to 3-3.5 turns and Factory Pro jet kit set up right.

Yes, I know I should just do it right, but will have some time this weekend to possibly get the exhaust system on and would not have the FP kits here by then. Is it worth doing it with the shims and riding it or should I just order the FP kits and wait for my next opportunity?

Also, I ask the next question because I can't seem to find the answer anywhere. I have new head/header gaskets but am wondering if the header to mid-pipe and mid-pipe to can connections each need a gasket of its own? I've read that those connections might not use gaskets but high temp o-rings or nothing at all???

Any and all help and opinions are appreciated!

Where the fuck does it says mixture screws at 3-3.5 turns out with a jet kit? I need to kick whoever said that directly in the testicles. Unless it was Tone, in which case I totally understand. I have no idea what number washer you need, I just know know you have to shim the OEM needles with a half step washer. Mid pipe to can, no gasket there, header to mid pipe, yes gasket is used there.

Thanks!

Looks like I got my info crossed over between looking at all the different posts on different jet kits.

Before you go enriching the mixture with the A/F screws, I'd try one size up on the main jets. Stock are 112.5, so try 115.

Keep the pilot screws at 2.5, half step washer on the needles, check!

Jets: 115 across the board? Or is this one of those motors that have one cylinder different?

No, they are all the same, so 115 across the board.

Did you ever figure the perfect setup? I have the same set up and I'm chasing a hiccup all over the rpm trying to get it right.

Riding every day and real life have gotten in the way of this project. All the parts are still hanging in the shed.

Finally back to this project' It's amazing what moving twice in a years time can do for all the projects one wanted to get done.

That said, does anyone have a reference as to what size springs I need to assemble this system? Those are either still in storage, in a box somewhere or have gone MIA. I believe that there are two longer ones for the header to mid and two shorter ones for the mid to can.

I'll see if I can track down the springs I have in the shop... I haven't moved recently, but it will still be a little bit of a search probably... lol.

That said...

You can still order complete spring kits for the V&H systems.

That was the first google result... some competitive price shopping may get better price / free shipping options.
