ok regarding fuel....
you have gone and done it you have let the geek out in me!
This page is from a fellow overlander who biked accross from London to Australia and was amazing
enough to keep lots of stats for me to enjoy...
The Statistics Fuel
The worst fuel was in Russia and Pakistan and had an octaine or RON 87
The octane number (RON) is a standard measure of the performance of a motor or aviation fuel. The higher the octane number, the more compression the fuel can withstand. In broad terms, fuels with a higher octane rating are used in high(er) performance petrol engines that require higher compression ratios. In contrast, fuels with lower octane numbers (but higher cetane numbers) are ideal for diesel engines. Therefore, high compressibility of the fuel matters greatly for only petrol engines. Use of petrol (also sometimes known as gasoline) with lower octane numbers can lead to the problem of engine knocking (the premature ignition of the air fuel mixture). This can destroy and engine!
you need to check the manuals for your chosen vehicle and make sure you "feed" it that value or better!

If you a really worried about fuel grade you can purchase octane boosters but lots of them don't work very well I have used Aldon Petrol Octane Booster and found it to be useful!
My K75 will work with fuels down to 89 ron so I will have to be careful in some countries unless I am adding additives! - basically don't work the engine hard!
