Thanks, Dan.
[MENTION=459999]josephgarvey[/MENTION]: The Koga-Miyata equivalents sold here all had bottom bracket-mounted generators, IIRC. Not original to this particular model, but much nicer IMO than the original bottle type generator: much less noise and cleaner looks. You'd have to move the kick stand, though. If you want to stay close to the original the VO bracket seems like a good alternative.
