2007 SkiDoo Summit 800 Questions

I have the opportunity to pick up a 2007 SkiDoo Summit 800 for a pretty good deal. I know it is not running, and I will have the opportunity to check it out, but I have also seen some information that the engine on this sled is ridden with problems as it was the first of its generation. Should I just steer clear of this sled based on that or worth checking out.

I was going to check the following:

Compression
Spark
Air
Fuel
Chaincase
Belt

I am somewhat of a novice. I have been working on an old Arctic Cat and an old Polaris. Got them running pretty well. Any advise is welcome.
