I just bought a 400 Series (1985, confirmed by SN), all it needed was a good cleaning, oiling, and adjusting and I have been riding it for three days now, 10+ miles a day. Great bike....does need new tires though
...they are on order from Nashbar. Paid $20 for the bike....stole it, stole it stole it. HEHEHEHE. Love the steel frame. Will submit pics soon.
