G'day Sprint,
Are you in the UK, if so, I've seen some pretty neat looking s/r's for sale
in the back of the Classic Bike Guide, prices seem to be a bit cheaper than
here in Australia. Keep looking, one will turn up, I wouldn't get too focused
on a particular year, just look for a nice old original bike, they're all pretty
much the same mechanically, accept for the cam, which you can change anyway.
regards, Cus
