Is the Manual in English? if so, that is the manual that I spent a ood amount of time translating into english (they never were made available in English, only Japanese) and have available for sale (see the NSR-WORLD.com marketplace, as well as the posts in this forum at the top), as well as sections available to supporting members online.

The English parts manual is available here as well. You can get to it from the "parts manual" link at the left of the screen.
