I was looking through some files on my computer and found this old how to for a foreman 500 snorkel. This set up is not the only way, as a matter of fact I did mine differently.
This is a list of the parts in order from air box to top of snorkel.
1 1/2" 45 deg elbow
4" long 1 1/2" pipe
1 1/2" 45 deg elbow
5" long 1 1/2" pipe (I actually went longer than this to get the reducer away from the motor after I melted one)
2" to 1 1/2" rubber reducer
11" long 2" pipe
2" 45 deg. elbow
8 1/2" long 2" pipe
2" 45 deg. elbow
Short piece of 2" PVC to connect 45 and 90
2" 90 deg. elbow
Short piece of 2" PVC to connect 90 to threaded coupler
2" threaded coupler
16 ga sheet metal I would use thicker but I had this laying around
2" galvanized steel pipe coupler
2" threaded coupler
A piece of 2" PVC how ever long you want your snorkel to be.
2" 90 deg. elbow or whatever you want on top of your snorkle
He used a 2 1/2" hole saw for the plastics and in the sheet metal.
I glued my pipe instead of the screws and silicon that this guy used.
I used the same route but I used a rubber coupling coming through the plastics instead of the threaded coupling and metal plate but I have also used plate and threaded coupling on other bikes. They both work well, the plate gives you a break off point if you roll it. On a side note, I've used straight smooth sided radiator hose as the riser on 1 1/2" snorkles so that it will bend instead of break.
You can also use 3 street 45's coming out of the air box instead of 2 with pipe in between.
