Mine came with a CV but I imagine the principles of mounting the CV are consistent. I have an aftermarket (maybe Screamin' Eagle) carb mount/filter for my CV. It's a K&N filter. What I found is the spacing between the bracket and carburetor (the depth the carburetor is pushed into the manifold/boot by the bracket) is critical. With mine I had a 1/8" thick metal spacer between the bracket and carb. When I reassembled I left it out first time through, thinking it wouldn't make a difference...

...bad choice. That 1/8" travel (of carb throat into boot) made all the difference. The bike had an intake leak and I couldn't adjust the carb. Put that spacer back in and all was well. As for the kind of air cleaner adapter kit I have, I don't know. It was on the bike when I got it. I believe I have a stock manifold. The principle here is to make sure the carb throat is all the way down in the boot, whatever air filter mounting device is in use.

As for the crank breather, my bike's got a metal plate attached to the tranny, the filter fits on that and the breather hose comes up behind. Just enough room to get a screwdriver in to loosen the hose clamp and remove filter for weekly cleaning. I find if I don't clean the filter every 1 to 2 weeks (about 500+/- miles) it will fill up and start misting oil over the right side of the bike when I'm cruising.

Another approach I've seen is to leave the crankcase filter out of the equation altogether and just vent the crank breather-hose directly into the atmosphere under the bike.

If your bike has the original manifold and rubber compliance fittings pitch it! They tend to leak. If you are doing the swap I would just find a used CV manifold. It's a nice upgrade and then you don't have to use an adapter.

Or if you can find a used s&s intake you could also use that with an adapter if you so please.

Stock manifold is fine for delivering the fuel of the carb.

Use a manifold for `90 and later, the original `89 and earlier manifold is a POS, those big goofy rubber compliance fittings were always cracking.
