what year is your yamaha vx with frame and engine number of 3JC-2186-01
No, the serial number on the engine is totally different from the VIN number on the frame. The only info you can get from your engine number is date and origin of manufacture. The frame VIN number and engine numbers are always different.
I have a Yamaha 80cc with frame number and matching engine number: G3 116632. I believe this is a european bike because the spedo is in Klm,s and the year is 1964

Its between an 81 - 83 model, in 84 Yamaha went to a 17 digit Vin number. Hope this helps. I have an 81 Virago with a 9 digit number on the frame and engine as well.
look at the number on the frame, it is either stamped into the side close to the engine, or it is on the frame under the handlebars If the engine was replaced as mine was then the numbers on the frame will not tell you if you have a later or earlier model engine.
