Hi Leigh, the following is a happy snap from a genuine 1980 Honda manual.
Will at least clue you on a starting point.

Whoops, missed that one.

There was a bloke I met at a Heaven meet last year that was looking for a copy of the Genuine 1980 250 Manual.
Any how if he sees this and still doesn't have one? PM me.

I think he was racing a little YZ and may have been driving a silver Lexus?
