I may be on my way to giving up on four-strokes, my polaris never forced me to hike in the snow.
For the second time I had a spontaneous oil change in my 03 RX1M.
previous --> www.ty4stroke.com/viewtopic.php?t=10465&highlight=
it happened this time while carving a left-hand turn, had the sled about 75 degrees from horizontal and got stuck. I packed the powder and got back on, started it up, moved it a few feet and saw the dreaded oil stream going into the snow, emptying the system. Had to hike back to the truck to get the extra oil that I had for just such an occasion.
Day ruined, belt ruined, engine bay full of oil.
Anyone want to try to make a case for why this is acceptable sled behavior? I suppose that I could carry extra oil with me; but, I can do that on a 2-stroke and the sled would likely be lighter.

I'm a trail guy, and I love my RX1, but I can't imagine trying to toss that thing around in deep powder. Just too damn heavy. If the 2-strokes served you well for your purpose, you gotta do what you gotta do. That oil drain thing sucks. BTW, where is it draining out of? I didn't think it hurt to turn these up with the dry sump???

I believe that condition is fixed with the Apex's new crankcase baffling. It is a much improved labarith on the front of the crankcase. my .02
Just improving the breed.

Take the crankcase vent as it comes OUT of the baffle, run a hose to the OPPOSITE SIDE of the sled and back, then connect to the airbox. Then when you turn it on its side, it won't dump out.

If you run a long vent tube you should do something to keep it from freezing up also. You probably could run a carb heater hose along side the vent tube and tape them together with insulated tape.
BTW, my stock vent/baffle used to freeze up after about 10 hours of cruising in -38°C weather until I ran the carb heater hose along all exposed vent hoses. No more plugged crankcase vent (and no more oil blowing past the valve cover gasket, no more blown PTO seals and no more oil consumption).

I like the vent tube mod as a possible solution.
I would like to try to reproduce the problem in controlled conditions though, maybe put it in the side with the nose slightly down and start it to see exactly where the oil comes out.
I shouldn't have freezing problems, almost never below 20 degrees here in No. Cal!
