I just sold a non-stock 1974 H2 and a few bits for nearly $12,000 yesterday. If it's original and in just decent condition - $8~10,000 US easy.
Now a word of wisdom - parts are also as high as the finished product. I sold a re-wound stator for $585. A decent seat will go for $700 or more. Just be sure what you want.....I've restored 8 triples and kept 6 of those. While fun, I'd rather ride my Honda.
Regards,
Gordon
