The rear diff, front diff, rear brake and the fan vent all are plugged into the frame in the front of the bike. they are not sealed up it you get your front end in water you can get water in all of these tubes. I would get some 1/8" tubing and barb connectorsfor the diffs and the rear brake and 3/16" tubing and barb connectors for the fan and run them either to the snorkel or the headlight pod. i used some tees to make less tubes and ran them into my snorkel. There is a tips page on triangleATV.com that tells you how to vent the crank case,I just did mine yesterday. The tubes are easy to find just follow the lines up and they all plug in the same area, the front diff puugs in on the other side i think. Hope this helps.
