I had a mint 250,  which I trail rode for a few months when I returned from europe.  NIce,  chuck it on the trailer and do whatever.  Good paint,  solid.  That was 15 years ago.  If I had the same bike now I would put a blanket over it.  Never remember seeing any 400C  in South Island (NZ).  My money is on the 400 man,,,,,,,,,,,,,  or PM me,  I might buy it from you.
