 Dubious is right on about the carb  and crankcase vents,
  Some of these are a check valve type to help keep "stuff" out of the system.

 Cam (I believe) found that billet R/C fuel filters look great and are serviceable

   You can also save a few bucks and use inexpensive auto fuel filters.

I don't think I actually sucked any water in. I just wasn't giving enough throttle and hit a large rock under the water that stopped me. I believe the modifications you are discussing are already done on that bike... I know there are some extra vents going into the airbox from normal, but I will check it out before hitting the water again.

The area I normally go riding is about 1hr north of Saskatoon (if you are looking at a map, it is between McDowell and Duck Lake).

Here's a few more pictures from the last time out. A KX500 is NOT in its element riding in snow with a bald tire. I'm putting a new rear on this weekend and hopefully tearing it up again Nov 11.

Cool,
Really nice pics!
Looks like your friend has pristine 87 ? (hard to tell from front angle) CR500
Hows the older CR500 run against the KX500?

My 87 CR500 was a brute, but signed off the pipe, almost as hard after the midrange hit, as it did coming on the pipe.
The procircuit pipe on my 87 CR500 really helped the top end power.

I doubt the 650 crank vent sucked any water in too, just bringing it up a precautionary.
 I have noticed that the 4 strokes especially need to have the carb vents rerouted, as the float bowl can't vent, creating a fuel starvation, and the motor then dies. The 4 strokes seem more suceptible to this, and they seem susceptible to cold water shock more than the 2 strokes too.

Yes, the 4 strokes are much better in the snow for traction, until it gets to be about 10 inches deep, then tire speed is an asset, and the big 2 stroke will leave em all behind! LOL

When I lived in Athabasca, we lived around a bunch of farms, and they had hay fields with rolling hills, the studded CR500 was blast and I could ride all winter in up to 20" of snow without issue. I would be out wheelyying the 500 across the fields with 20" of snow on the ground doing 60 mph! haha.... good times. Crossing packed skidoo trails at that speed is pretty interesting, lean waaay back squeeze the tank hard and pin it.... LOL yes I ate sh#$%*t a few times...LOL

That bike is an 86 CR250R, and it is pristine. He also has an 86 CR500R as well, that is in nearly as good condition, but not quite. We still have never ridden the 500s together, he is always fixing on his CR500, or just feels more comfortable on his 250. I'd like to run them against each other sometime, but I think the weight issue is going to seal the deal. He is about 100lbs lighter than I am, which on an MX bike makes all the difference in the world.
