Off on tangent - but:
I read the report in one of the magazines a cpl weeks ago on this. 100# gain seems awfully hard for me to believe. I know that Bill was replacing his footboards with plastic so that the snow wouldn't stick to them. But any newer sled will have grated footboards now anyhow. Kan't be THAT much build-up there anymore... (?)
One big thing is if you run through open water. Get water up in the rear suspension and it will get REAL heavy 'till it thaws back out. Not if you are on trail or broken trail I guess, but if you are running point and splash through the water, and it doesn't have a chance to git back out before you get back into deep snow - it will turn to one big block of ice. We had to spend an hr one day chipping ice out of my sled after running point early season. Once I stopped - there was no re-starting again until it was chipped out. My chum was the only other one with me, and since he was running 2nd, he didn't have that trouble.
So - I kind'a wonder if the guy who said that his sled gained 100# - I'm wonderin' if he found a crick during his ride and the others didn't?
Also - I found it quite ironic that in the vid that they claim that they have reduced build-up on the Kitty b/c they have shorter heat exchangers. We have found the exact opposite to be true in our experience.
Posted below are a cpl pics of my chums Edge chassis RMK. Those have a dink little exchanger just above the snow flap as you can see in the first pic. That sled liked to build up loads of ice from the end of the exchanger - all the way up to - at least the mount point / carrier wheels of the rear suspension. I imagine that there was build-up further up the tunnel, but it would have been thin...
You can see in the pics how big'a chunk we pulled out of there one day.
My chum fixed this by fetchin a Doo cooler and retrofitting it in place. His sled ran cooler (the Edge always ran on the edge of red) and never got anything like this build-up again.
It's kind'a hard to see, but he is holding a big chunk of ice in the 2nd pic.
Still tho - water is roughly 8#/gal. To total 12 gal of water clinging on seems a bit hard to come to terms with.... ???
But - if the rear susp is as full as my chums shows here ... may _ be?
Also - this was just cold season bush-whackin'. No cricks that day.
