Wondering if the engine parts (or any parts) are interchangeable on the different R5 years? I have a 1970, and will need to do a little work on it. Thanks

Not 100% but they only did the R5 for 3 years. I doubt they changed much. Probably find a lot of RD350 parts will fit too. Yamaha are pretty lazy that way.

If you go on the yamaha-motor.com website which is the USA site and click on Sport then parts and service and view parts catalog and select motorcycle you will find a parts catalog that goes back to 1963 and shows the 1970s R5 parts so you can compare the part numbers .Tony.

that yam site is good i have the european parts list and a PDF of the R5 gen workshop manaul for europe if you need one

and this article is good r5 resto
