Just finished restoring a 73CCM 580. I know they had a very interesting start technique. She will roll start down a nice hill, but I need to gently roll on the throttle after the pop,pop,pop before she lights up. Roll the throttle too early and its lock and slide. Being 52, with raging gout in ankles badly broken fom speedway accidents years ago, kick starting it basically impossible. (managed it once when she was nice and warm and then found walking (hobbling)intertsting for the next two days) Wondering if anyone as ideas how a set of rollers or road racer starters could be used to make starting an easier chore. She a 580cc with 11 to 1 comp, running motoplat ignition through standard amal and 100 octane fuel. Mikuni may help a little but probably not enough. This email is directed towards the old boy brigade as I know you fit younguns wouldn't have any trouble! Interesting my 18 year old who rides a 250F struggled, just shock his head and walked away after about 10 attempts at trying to start it and ride it, muttering things like everything is in the wrong place and it won't shift under stress for shit. guess age sometimes does have advantages.
