On my 3000 mile trip last summer from here to there and back, here's the fun stuff that happened:
- no fuel at Denio Junction, OR (middle o' nowhere), K had enough in the tank to make it barely to the next hop but I was sweating it for that last 50 miles. No reason to think there would not be fuel there but all out of service.
- bike _barely_ started after camping in sub freezing temps at Great Basin Natl. Park, fortunately it fired up. Weak battery (although not old). Bullet dodged.
- low beam burned out going up the curvy mtn road at night, I carry a spare repl. the next AM, had to be the a-hole to the downhill traffic that PM with the brights on. Fun though with about 4 billion moths in the air, looked like a snowstorm.
- oddball fuel return issue caused fuel to dump out the overflow hose in nontrivial quantities in the desert heat. Easy fix but I did not know what was going on, online K bike gurus gave me peace of mind to just ride it home and address the issue once back rather than squander $$ and time at some Colorado BMW dealer, which was my first thought.
So to learn from my experience:
- have spare fuel or don't cut things too close
- test your battery, make sure it's great
- bring simple spares (bulbs, etc.)
- have internet access to check here if you do encounter an issue or two
Half my issues were the bike being in conditions it never sees at home (below freezing and above 100F). No wheel issues, this time anyway, I carry a flat kit but never used one, hope never have to learn.
