Gidday mxs,
My advice would be to stay well clear of it, unless of course its an absolutely mint low mileage example - purely from the point of veiw that it's an old domestic market model never destined for export outside of Japan...
The expected service life for a "Domestic Market" model is 7 years - after that expect to start having trouble sourcing parts new...
THIS APPLIES TO ALL DOMESTIC MARKET MODELS NOT JUST THE ZXR'S...
Off the top of my head, parts that are now N.L.A (No Longer Available) include:
Pistons (Std & O.S)
Rings (Std & O.S)
Inlet Valves
Exhaust Valves (shortly to go the same way...)
The bulk of the "Plastic"
Your best source for parts would actually be some of the vehicle auction houses in Japan (you'd be buying a complete bike, obviously...) - they bloody near give the things away as they are worth nothing locally...
Cheers
