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
