I have a Japanese year 2000 NX5 manual, it's missing the front cover, but its an original one. Happy to swop for an MC21 F3 manual (also in Japanese) A copy or original is fine.
The '97-2000 was a bit different to the '96 as it was made for unleaded and had powerjet carbs, air scoops in the tank etc.
