    Customer 4" intake tip

    For those of you making your own SC intake, I came across something you may find useful. I was not sure how I was going to connect the crankcase vent hose to the 4" tubing that I was planning to use. However after removing the factory intake system I noticed that the inlet for this hose comes off of the stock SC hose. It is a small piece roughly 3" long. So just determine where the crankcase hose should mount or line up to the new 4" intake and cut a hole just roughly an 1/8th in diameter smaller than the stock inlet. It should pop right in and not come out, unless it is forced. The inlet has a wider diameter at the bottom then the rest of it.
    I had taken a few pcitures to illustrate the above but my wife inadvertantly deleted them. Sorry. Hope this is still useful.

    Good idea, but many here try to keep the oil and additional gases from the motor OUT of the intake track. A "catch can" is a better solution for the breather.

    I agree about the catch can, and I plan to add one myself. Just for the mean time this solution will do.

    Catch can "IF" you have oil in your intake. 50 hrs here and intake is clean and no oil and with stock breather setup.
    Funny why some blow oil and some don't

    It seems that many of the heavily modified skis blow out a little oil and air from the tremendous pressure inside the case. I ran my ski as a Stg II for 50 hours w/out one and was fine. But as a III, I emit more smoke than oil. I feel better that the "combusted air" is out of the system.

    I have 70hrs on my ski and when I took the stock breather off I defintely noticed oil in it. May have been because my dealer over filled it after the 10 hr and again after 30hrs.
    I do the oil changes myself now
