GG: We used to use washing up liquid in the 70's! (how's the weather over there by the way? Any chance of riding one of those "desert bikes" that we see on the TV? I understand they are diesel(?) to fit in with the US's "one fuel for everything standard?
It's actually colder than a witch's teat. I'm up in the mountains and it's not the hot desert everyone thinks it is.
Regarding the desert bikes, the Military uses the Kawasaki KLR650, modified with a diesel engine, though most all Army Diesel vehicles run on JP-8, which is an aviation fuel. Yet more cost-cutting: "Hmm...I wonder if we can run our trucks on what we use in our helicopters..." It actually works pretty well, since a diesel can run on pretty much anything, but a helo can only run on Aviation Fuel. The diesel KLRs are sweet: 100+ MPG, tough as nails, reliable, and actually pretty fast. I would LOVE one and there is a company selling them, but they run about $10K on the civvy market.
Currently, only Special Operations guys use the KLR, and the military is wanting to go away from motorcycles in favor of 4-wheelers. Their rationale is that a motorcycle takes both hands and both feet to operate, leaving the operator no open hand to fire a weapon. However, there are videos where SpecOp guys are roaring up to an airfield on KLRs with a pillion passenger and the pillion is firing a machine gun for cover fire while the driver drives. It's also harder to operate than a 4-wheeler and I think the military didn't want to spend the training dollars. Also, people were doing dumb stuff when they got bored and hurting themselves.
Between soldiers getting hurt on and off-duty on motorcycles, I am serious when I say the US Military HATES motorcycles and I am not lying when I say that they would absolutely outlaw their ownership or use by servicemen if they could.
