PW50 - 80 year models

Hey Jam are you going to use the Yamaha VIN decoder? I have already tried that and it requires a 17 number VIN to work. My Yamahas all only have 12 numbers in their VIN.

Maybe because mine are Japanese domestic models that I imported myself.

If you aren't going to use that method, say so and I will get the numbers to you via PM.

Apparently somewhere on the rims there is a date of manufacture stamped there as well. I read that on our own Aussie trailrider website but haven't verified that as of yet..

I will have to move 10 push bikes and other assorted pieces of junk to get to the PW's in my shed so I will get back to you with the VIN's.

Ring a Yamaha dealer with your vin and they can tell you. I have also been told from a reliable source that there is a date stamped on the rims of the 50's but haven't verified this.

somewhere, on something will be a date stamp. It's about as reliable as anything else. Often these are circles with a two digit number and a clock looking stamp that has a pin missing. Engine cases are a good place to look.

Aside from that, I don't have much info. My understanding is that from 1982 forward, VINs were standardized and the only quirk is that 1980-81 had some date stamp issues (8th char) but after that, all were the same until next year when the date stamp will be recycled starting with 0 again, the same as 1980.

Crap, I did it again. 8th char from the RIGHT which is 10th from the left on a 17 char vin. Sorry.

If it's not a 17 char vin, there is no reliable method to determine the year between all the manufacturers.

Found out about the wheels having dates stamped on them too...wheel says 84...so 84 or 85 is close enough. It's frickin old!!!!
