Vintage Dirt Bike Q & A

Ordered a NOS kick starter for my 74 MT250. The one i recieved is designed differently than every other kick starter i have seen on Ebay. I checked the splines with the kick starter shaft i ordered and they seem to be a match. The splines are so small, it will be hard to be 100% certain to tell, til we rebuild the motor. Old kick starter splines were rounded and the previous owner welded it to the shaft. The part number they gave seemed to be the correct one... 28300-358-770


Here is the listing for the kick starter i ordered. Hopefully it should still show the picture.

These are listings for the original design:

Anyone know why this is?
