When old ideas are the best! A bloke was telling me today that the BSA Bantam had a measuring cup attached under the fuel tank cap for the 2 stroke oil. That is fucking genius! As the owner of a 2 banger one of the issues is carrying something to measure the oil and then put it in your backpack without getting oil everywhere. I'm going to re invent it, take the idea onto that TV show the Shark Tank and make a fortune!
