Know problems so far:

-'08 model had a poor air breather design, sorted out in '09+ models.
-Some early '08 had a problem at the reglator wiring loom connector, looks lie is it sorted out on new models.
-The wiring loom below gas tank may do some ground contact.

None of the above are big issues and can be fixed anywere with litle effort using "African reources" and 2 of them have been fixed on 09+ models.

Honestly, I would prefer and old carb bike for a RTW trip, but the last time I went to Africa one year ago I was on a truly reliable bike -Suzuki DRZ400- and I end up with a broken conrod and a grenaded engine .

I have done 40000+ km on the ten and even with all the the electronics and EFI I would use it in a RTW trip.

About the gas tank, using crapy Morroco petrol I have managed to do over 300km per tank on trails at non-racing speed.

have fun,
