Hey, I need some help, I recently purchased a 83 yamaha midnight virago 750, and the fellow I bought from said the motor had been changed....I can't find out the year/make,model of the swapped motor.....the engine number is 5E3-001471, and the
VIN number from registration is 20Y000516 (which I guess indicates yamaha 750)...however...I don't know for sure if my engine is the one the reg. says it is....doesn't seem to be........also, would this affect the kind of TCI unit I have under the tank....(metal one with pigtail wires, or plastic with plugs and no wires)???.... which on should I need on the 83 yamaha midnight virago 750???......any help would be great.
