    Don't remember seeing that post. There is a list of FZR parts in this post
    <!-- m --><a class="postlink" href="http://www.fzr250.com/viewtopic.php?f=20&t=911">http://www.fzr250.com/viewtopic.php?f=20&t=911</a><!-- m -->

    The 3LN file does list parts for all 3LN models despite saying 3LN6

    I'm also interested in what bearings you managed to get as we may be getting some cranks reground and will require bearings.
