1972 Yamaha DS7 Service and Repair Manual

DS7 is the model code, 1972 the year, and LIT-11613-60-20 the Yamaha part number of the service manual that covers it.

The book was written for the 1972 and 1973 model years and it takes in the R5, RD250 and RD350 alongside the DS7. Those machines are close relatives, which is why Yamaha documented them together and used model callouts where a specification or a procedure differs.

Inside is the factory workshop material: engine and transmission dismantling in sequence, inspection limits and assembly clearances, carburettor and ignition specifications, chassis and brake procedures, torque tables, wiring diagrams and troubleshooting organised by symptom. For a twin of this era the jetting and timing data alone justifies having the real manual rather than working from hearsay. Confirm the DS7 code on your frame against the fitment list before ordering.
