Yerf Dog chain size???

[Rarerat]

I have been looking for a different sprocket to change the gear ratio on my daughters Yerf. Currently it has a 13 tooth counter shaft & a 31 tooth axle sprocket. It runs great but with the 22x12x10 paddle tires in the deep sand it raises the gear ratio so high that it becomes the gutless wonder. I have been looking around for a different rear sprocket and found a 37 tooth on egay for under 20 buck shipped. It is for 420 chain, but I am not sure what the Yerf chain size is?? Anyone have any ideas or know anyone with a 38, 39 or 40 tooth sprocket for sale??

Thanks in advance

You can get a 530/#50 chain 39t sprocket from Buggy Depot or Mc Donough Powersports.

This looks like the correct sprocket (check your bolt spacing):
