What should be the stock rear sprocket size be on a 2005 400EX? I thought it was 38T, so I just bought a PD 38T sprocket. Lo and behold, when I pulled off the original sprocket, it was stamped 39T. I bought the ATV used, so the original owner may have swapped sprockets, but he didn't mention that when I bought it.
I'm going to be running 23" fronts/22" rear tires and just bought a 13T front sprocket to gear it down. Can I go ahead and use the 38T that I just bought or return it for a 39T?
