71duster

Hey guys I own a super nice 1963 1/2 Yg1 unrestored, so I don't need parts but owners manual, but don't want to spend $75 + for one, you know recommend'd oil, how much ect. It's pre oil injected model & there isn't any info out there so if any one can help I would be grateful, thanks. Now for you guys that need parts one of the biggest NOS stock piles is at st. louis donalson cycles been Yamaha dealer since 1962 & has kept all his old stock make sure you talk to Carl,, hope this helps good luck
