I watched my 2012's compression like a hawk from a 1000 miles on. I had 120 in both holes till 2000 miles. The pto side dropped a little and I tore it down at 2200
to find a cracked cylinder skirt. The final reading was 117/120.
When the trails are frozen and the factory scratchers don't cut it, I throw on some stainless all thread onto the backs of skis.
3' of 3/8" is $20 at any hard ware store. I put some fender washers on to distribute the pressure on the skis.
Does anyone have the ogio tunnel bag? Did you manage to mount it securely enough so it doesn't flop like an
epileptic fish out of the water on the trail ride up?
I've got around 800 kms right now on a unit with a 163" X 2.6". The front end has survived a few good blows. The belt isn't wearing any worse than the ones for my 2012 pro. The rear skid could use some adjustment for weight transfer.
I tried a friends sled (13 pro) with the pro motion, but it also has a 35" front end. It's basically a snow bike with a large 3" paddled
track and 2 skis!
