got a chance to give it the old tyre kicking today.
the good: motor runs and sounds good, paint in good nick, tyres will do, under years of grime and some sort of heavy clay #$%* the chrome will clean up nicely.
the bad : needs new throttle and clutch cable, a tear in the seat, needs new throttle barrel, front brake and clutch perches and levers, exhaust is toast
all in all I'm a happy chappy.
Edit.... back tyre just blew bugger.
