HI jennabusa. Really seems like an awesome trip. Were you on a R? how did you get a 22L tank. I'm looking at doing some trips through African countries and seriously need more range. I am in south africa and not too much available in terms of mods here. thinking of fitting DNA stage1 & 2. Anyone have an idea what it will do to my wade depth?

hi henk,this reply might be a bit late,but to help you i replaced the "r" exhaust with a 2/1 from metal mule, on the opposite side a friend of mine made up a false silencer , actually an oblong alloy box with a filer at the top with a breather and a fitting for a plastic fuel pipe at the bottom, i then drilled a hole in the main tank and fitted the other end to that.I then took the fuel cap to pieces and put a pen spring behind the breather ball bearing ,so that the only way the main tank can breath is through the auxhilary tank ,which when filled will suck fuel through to the main tank.
this may sound complicated ,but is simplicity itself and works a treat as long as you use a small dia. pipe and keep the main filler cap sealed.

Great pics from the sibirsky site, still saving for somrhing similar. And clever stuff with your auxillary tank!
