i'm going from Michigan to Alaska and back this coming summer. I'll be riding from Fairbanks to Deadhorse (gravel) and i'm also going to make a side trip to Great Slave Lake. i've been to Alaska before but never on a bike. i'll be riding a 2007 R1200GS with 37 K on the clock. the bike has always been shop maintained. it has new street tires and will get a new battery. i plan on having knobbies installed in Fairbaks prior to the ride to Deadhorse. the bike just had its 36K service done 1K ago. i'd like to know what you all think i should consider doing or checking on the bike before i head out. Many of you have ridden a 1200GS to Alaska and back. thanks..
