Hey guys, I just picked up a '75 Yamaha MX400 and before I start tearing into it, I'd like to get a shop manual like a Clymer or similar. But I'm having trouble finding one for this particular bike. I can find them for earlier MX models, for the DT's and for the later YZ's, but so far nothing for this exact bike. Does anybody know if I can use a manual for a different model Yamaha that is interchangeable with the 400 MX? Also, any advice on a good supplier of vintage Yamaha parts, other than fleabay? And is it still possible to get the monoshock on this thing rebuilt? Thanks for any help!
