I try to check this thread from time to time, it seems people are still using my write up (which is good- that is what it is there for).
This was done in my more amateur days of snorkeling, but I'm still proud of it and have done several other Sportsmans (And Arctic Cats, Hondas, Kawaskis, Yamahas.... etc..) the same way with no problems whatsoever.
The most annoying part of any snorkel job is getting the airflow right, The Magnums didn't use the same carbs as the 500 HO Sportsmans (but did use the same as the pre-H.O. models). It would be hard to say whether or not going with 1.5 would be enough. However, you can always restrict airflow once the snorkels are in place by simply putting some electrical tape on the snorkels to restrict as necessary. It isn't the best way to compensate, but it is the easiest and still maintains an (in my opinion) acceptable route to get the air/fuel mixture close to factory settings. I always prefer to err on the side of caution and will take a rich mixture (more fuel/less air) over a lean mixture.
I used to have a magnum I snorkeled in a similar fashion to Caleb. I used a short piece of thin wall pipe and put it directly into the original stock rubber snorkel. I think it was 1 1/4" pipe but not sure. The thin wall pipe allowed it a very snug fit but didn't restrict the air flow. I then adapted it up to 1 1/2 and ran it to the rack and up.
My buddy and I spent a lot of time online searching around for a his '12 Polaris Sportsman's snorkel instructions and managed to find a guy who had made an instructional on an '08 model of same (or rather very similar) body style. We bought about half the parts and waited a few weeks before...
OK, so here we go. Parts list and how to run the pipes for Ranger 900 XP. First off, I have to mention, that apparently from the first production 900's, to the newer ones, they made a design change to a bracket behind the middle of the seat. Making it not possible to run them up the center...
