Congrats! Dual sports are so much fun, be careful, you just might really like this kind of stuff.
My personal opinion of the KLR is pretty poor, I had a '98 and rode it for a couple months before I figured it wasn't the bike for me. The KLR is the perfect ride for Adventure riding, but IMO they suck in the dirt, they're not that great on the freeway and do most everything marginally well.
There are better bikes out there, but the KLR is a good beginning bike since it comes factory with a large fuel tank and is capable of dirt & road riding. I would imagine yours was cheap, so that's always a plus. I think I paid $1400 for my green one.
