i have a 71972 750 roadster commando that begins to wobble at about 60 mph. I'll try to describe the symptoms. It feels as though the steering is too sensitive,as though there needs to be a steering dampner in order to create a bit more drag,or perhaps it can be likened to the feel of a very over inflated front tire.The handebars wobble left to right when I don't hold them tightly. What should I check and how etc????thanks in advance, ace

You are describing fairly classic symptoms and there is no doubt that Commandos are very sensitive. The trouble is that there is no one problem and no one simple answer. They shouldn't do it but lots of them do at various times and the cause is often a combination of factors.
Has it always done it ? Has it begun suddenly ? Have you changed anything ? If ever there was a bike where you should only change one thing at a time, it's the Commando !
The traditional Commando head-flutter normally arises at lower speeds ? How heavy are you and what handlebars do you have ?
Does it threaten to become a full-blown tankslapper ? Does slowing down or speeding up make it better or worse ?
