If you plan to take the Canadian L902M I caution you to take great care to find the current condition of the trail. A friend and I did this a couple years ago and had lots of difficulty with the trail as it hadn't been brushed for several years. We wound up turning back to Northern Lights resort and convinced (paid) the owner to trailer us to Atikokan. Long story...I believe that they are now maintaining it again. If you haven't ever been to these areas, I just caution you, I have never in my life experienced such remote territory! Not trying to turn you off, just make sure that you and those in your group know what you're signing up for. If something goes wrong, there is really no civilization whatsoever in this region. We were doing the Atikokan Circle Tour, its a great loop, but snowmobiling from Gunflint to Atikokan is a whole different deal (was then anyway) From Atikokan to Crane Lake (MN) is no different than normal MN riding.
I put alot of research into the trip and I do have some maps, phone numbers, etc and I'd be happy to share some info, I don't know if the numbers I have are personal or business numbers so I'd prefer to send them directly to you.

Make sure to be in contact with the Atikokan Sno-hos and Thunder Bay Adventure clubs as well as Northern Light Resort And Quetico North.
You should be applying for remote boarder crossing passes and its suggested to do the loop counterclockwise as there is no US checkpoint in or near Gunflint. The folks at Gunflint lodge don't seem to be all that snowmobile friendly, perhaps it was just the guy working that day, but definetely more of a "quiet snowsports" kind of place.
