BSA side valve industrial engines were, at one time, a fairly regular sight, powering rotovators, cement mixers, conveyors, lawn mowers etc, indeed I even had a 420cc side valver on a garden tractor. However, this is the first time I’ve ever seen a Bantam engine used in such a manner. It was spotted on a trailer at Stafford and on sale at £275, which was a bit spicy considering the overall condition – and no guarantee that the engine was any good either. It certainly looked a proper job, not one someone had cobbled together, but I bet it wasn’t the handiest thing to start with the hand operated kickstart – and why a gearbox? Surely it didn’t have three or even four speeds in there? Flat out in top across the veg patch, now that would be something to see!Enjoy more Classic Bike Guide reading in the monthly magazine.
