My name is Trygve Klem, and I live outside Lismore, NSW, Australia. I have recently bought a CB 750 SS 1978 model. Which I have started to sort out the various areas needing some attention. When I opened the dynamo cover where the stator is, some oil leaked out. Is there supposed to be oil in there. (as you can guess, it's a long time since I have owned a motorbike.
