Looks like the sprocket is a JTR-809 sprocket, it crosses over to fit a Suzuki. I have no clue what it has for wheels and hubs, i guess since everything lines up I will just run it.
I have a 1977 ty250 that has a non original rear sprocket on it. As far as I can tell, when looking up part numbers, the original sprocket was a dished sprocket. The sprocket I have is flat non-dished. When i look at the alignment it is in line with the drive sprocket. the chain is straight and runs true. Any Ideas how this can be with a flat sprocket? There are no spacers on the front or rear sprockets.
