Engine was produced on the 22nd of May 1977 which tells me either the engine has been changed at some point or the Air cowling has been substituted due to the starter assembly failing.

The colour of the machine tells me it was built prior to the end of 1976 when SB changed it's colour scheme from Alpine Green to Apple Green.

I live a 24 Hour lifestyle, but every now and again I seem to fall asleep, well at least that's what my wife tells me.
