My 9 year old son is pretty stoked on his 3203 Yerfdog... until he hits the hills, and our property is pretty much all hills. I plan to adjust the torque converter spring to the #3 position to get it to shift later. Additionally, I would like to change the driver sprocket from the stock 10t to a 9t to get a bit more climbing torque. Can someone who has done this before please send a link to the exact part?
I found some 9t sprockets here:
http://www.*****************/sprocket.htm but i see one with a keyway and one with a built-in key. I know I could disassemble to see which one I need, but I have limited time. So, it would be a big help if someone could tell me which it is I need so I already have the part before I take it apart. Also, if you have a better parts source than the one I posted, please pass it on.
Finally, how do I keep the driver pully from spinning while I loosen the bolt?
