Feel free to correct as needed. Seen Specs missing on left for this model. After all the help/advise/tech tips I received on my project from here, thought I would try to give a little back. If anyone can use these. I'm somewhat of the 'ol pack rat- this book is from '74 -'80 Specs ( some '81) for Yamaha Models. Kept ahold of it from the Yamaha dealership wrenching days back in the '70s-'80s.
