  • Q:

    I have purchased a manual for a 1971 & 1972 Triumph T120R and all the engine #s begin with a DD - - - - . My engine # starts with a EE. The full # is EE22652. I bought this bike in London on June 7th 1971 while touring Europe. Now after 20+ years I want to restore it and cannot find a manual to help me finish it. I really need a manual for this bike. Formost I need a manual with the Electrical System for this bike. None of the Electrical Systems in my manual have the same color codes for the harness wires. Can you help me?
