Air-cooled rotary project: Matterhorn

A while back I started shopping around for an air-cooled 2-stroke snowmobile engine that I could possibly put on a custom made motorcycle. Instead, I discovered that Fichel-Sachs had made a 303cc air-cooled rotary(wankel) engine back in the late 60' into the 70's with 25hp and a sweet sweet pull-starter. This was an optional engine on old Arctic Cat sleds. It would pull the sled to around 35mph but from what I understand it could pull almost anything. After months of shopping/searching, I was able to get my grubby hands on one and the project had it's first component.
I finally settled on the fact that I'd have to make a frame from scratch to satisfy my needs. I knew I wanted a skinny lane-splitter and long and low.
It's a German made engine, so this is my first European bike forum thread.
Enough of the story telling, here are my first pics of this build, aptly named "Matterhorn: Ice, Wind & Freedom"
