heh! i thought of the daddy of them all!. you know the small liquid soap bottles, push the top and smelly stuff oozes out, well my tengai had one fitted onto the frame lh side as you rode along give it a pump now and then, the oil flowed down the tube onto the sprocket. simples

you decided how much oil to the conditions, how could it get easier

went up market, bought a new tenere,soap bottles not good enough for my precious, went and fitted a scott oiler. progress
