This is the link for the 1966 U5 parts list online that is savable printable (not the U5-E model). I bought a U5-E Service Manual that I am happy to photograph, and make available here. Is there a section of the bike that you need the most. It's like 60 pages I think. Stan P.S. The photo is of Edie Henderjack and the 1968 Lady Yamaha that I bought for her mama, and now have pretty much gathered the missing parts to paint pink! https://www.yamahapart.com/oemparts/l/yam/547f3b74f870021f60c94563/1966-u5-parts
