Dated 1972 3 YEARS after they were imported into the US, I am wondering if it was a Canadian or Non US manual. There is a picture of an enclosed rear chain which US bikes did not have.. All S90 models have the same tuneup specs. The cover shows wear, but inside is great. Includes factory wiring diagrams both US and Export models.
An absolute necessity for tuneups and maintenance. Make your bike run like new to factory specs.
