Yamaha MX-1000 repair/refresh

I have an old mx1000 in need of some love. Years ago the local dealer told me a few parts he couldnt find so he was no help. I have emailed Legendary Amps about it, but got no response.
It has sat for 10 years in need of repair. Its time! I replaced it with a Yamaha MX-D1, which is stunning, but I still want this classic power horse running again.
Any advise, help, or suggestions are welcome as I cant seem to find anyone to restore it.
