So Awesome!!! So much of this represents, in my opinion, the future of mountain snowmobiling. The "going skinny" trend isn't going away any time soon.

Then it's crazy to think how the Hawk was rejected because it was here 30 years too early.

Agreed. I'm a little surprised the Hawk wasn't more popular. I thought they were an awesome innovation when they came out. I was in no position to purchase one at the time but would have if I had the funds. That said, I'm really excited about my builds. I'm hoping my Yamalaris proves to be even better than the Unicorn.

I'm starting on the shrouding. This is progressing easier than I anticipated. The biggest challenge is building a cover for the primary clutch. I haven't quite decided how I'll do it. My thinking is that it needs to be quite sturdy to protect the clutch from stumps, logs, and rocks lurking under the snow. Also, it'll need to be able to protect the clutch when the bike tips on it's side. It also needs to be "snow tight" so it doesn't allow snow to get inside and make the belt slip. I have a few ideas. We'll see what transpires.

The other criteria for the clutch cover is that I need to be able to get a belt on and off easily. I pretty much screwed around for an entire day until I came up with a solution. First, I welded on some flat bar to the frame that I can use to secure the cover.

Next, I fabricated a skid plate.

I can TIG weld aluminum...........barely. This should protect the clutch enough. I’ll use plastic to cover everything.

Pegs between the clutch and the drive shaft or a very short set of boards?

Footpegs are going to be mounted about 10" behind the driveshaft. Right about where the suspension pivot shaft is bolted through the tunnel. This is about the same foot position as the original RMK.

Been working with the TIG welder trying to finish all the aluminum welding. Got the motor mounts stuck together.

I welded up an oil reservoir.

Because of the shape I had to use for the reservoir, I’ll need to add a sump off the front so the oil pump doesn’t starve on steep hill climbs.

I routed the coolant lines.

Everything is looking pretty clean. I have a good amount of room for the airbox which I’ll tackle soon.

I finished up both skid plates to protect the primary and the stator.

The Hawk was just too far ahead of it's time. It was too early to get the benefits of more modern sleds like lighter tracks, lighter chassis, fuel injection, etc. It would have been much more liked with these modern improvements.

True , it also was designed to take a beating like a dirt bike . Designed for anyone that can turn a wrench . Times have changed , disposable era . 16 years and it still does things that many of these new machines can't do . My apologies for the interruption , no substitute for power :)
