Again, I think a DR650 would be a better choice for jayareus and his particular situation. Unless he chooses a pre-08 KLR that's been well-maintained and the doo done. Then I'd say no worries and ride the thing.
Doug's (my husband) '08 KLR burned oil from the start, and we've been all through the doo fix and 685 kit. We did the work ourselves but I wouldn't call it simple by any means. A big enough pain in the ass and pocket book for sure and we're old established folks, at least for the rednecks we are. It would have been a hard hit and tough to manage back in our starving student days.
