Why would you or anyone else want to swap injection for carbs? For economy & ease of maintenance fuel injection must be the best thing to replace carbs on multi-cylinder 4 stroke machines! Owners of the original Mini fit carb bodies,such as a bank of Amals, but that's to do with performance and replaces the single CV carb. Unless anyone else knows otherwise,i havn't come across any 2 stroke bike fitted with fuel injection.
