The output shaft you are referring to IS the shaft that the chain sprocket is pressed on to right? And when you say "teeth" you mean on the sprocket? and not number of splines?
The 15 tooth chain sprocket has always been the stock one, but many members have changed them for a better (slower) ratio.
When I first read this I thought you meant the shift collar, and there were at least 3 different versions of those. Shift collars are a much more common replacement part than the output shaft. Most people just replaced the sprocket instead of the whole shaft. I thought a 12 tooth #60 chain sprocket had been tried and would not work due to clearance problems. If your old sprocket had the tips torn off, make sure the chain is not touching the shaft itself. The chain needs to sit down into the valley of the sprocket.
