I own a 1982 xj650, in my opinion the most fun and powerfull four in earlys `80 Despites it´s retro look. Anyway I have observed that having the bike too many time stoped in the garage makes ignition go wrong. I had some troubles with engine carburetor, that needed repeated spark plug replacing. Apart of this and it´s too narrow back tire, nothing to say: Splendid! J.R.
