150 mile update
So I have taken this thing out a bunch of times now, with the kids and some group rides. The temp stays fairly normal but I do think there is a bit of air in it somewhere. I have a hill on my lot that I'm going to take it on and I have turboflash's bleeding procedure somewhere. Playing around with the kids on the lake yesterday it did seem to stay in the "normal range", it would spike to the 200's when turning it off and leaving it for a bit. But running it around it would drop back down to normal fairly quickly. Trail rides have been pretty normal for temp and if it gets warm I drop a boot.
I got some long #*$&@ scratchers, 12" and I'm trying to figure out where to mount them. I have mocked it up twice now and it looks like the cable will be hitting the snow even when its up. I'm thinking about getting the ibex scratchers and rail mount them

A new problem is the hyfax I took off unfortunately still had a bit of life left in it but I'm playing it safe. The new cat dealer hyfax I got will not butt up against the rail tip. The bottom green is the one I got off the sled, the middle is some garland from denniskirk, and the top is the dealer green. I really want to run the green as it has a nice contrast but again there will be a gap between the rail tip and the hyfax. Yeah I could turn it around and redrill the hole but I just want it to work from the dealer.

I'm also going to look at the rear suspension soon, there is a pile of ski pressure and it gets to the point where I have to muscle it around. There is about an inch of thread showing on the front track shock and I think the straps are all the way out. I'm going to lift the rear of the sled up and down a few times and see if the skid touches at the same time. The kids zr 4000 rr can be steered with one hand but it also weighs less.
