Yeah it is the speed. All the guys I met on KLRs stuck at 60mph religiously on the highway. Single trailies aren't made for highways really. They can do it, but 70mph is a bit on the fast side. That poor piston is bashing away something rotton.
Having said that, fully laden, as you are, my Transalp twin is the same for fuel efficiency as your KLR. I can hear/feel the main jet in the carb taking up the squirting job in earnest once I hit 93 km/h, and then the reality of one pound a litre becomes all the more real for me.
Fuel injection bikes are different though.
