Finished off the last couple jobs today.
Felt a little bad about butchering the inner belt cover but it wasn't in great condition to start with. I turned an extended crankcase stud nut to use as an upper mount having removed the old upper mount that no longer fitted due to the increased diameter alternator compared to the dynamo.
Also had to make a new outer battery
strap, the original was a casualty of an early test ride. Unfortunately the flat bar I had was a little thicker than the original but it'll do for now.
