im thinking of dropping a tooth on the top gear on my mxz for better low end pull, and i want to know what size chain i will need, and what size gear. if i only drop one tooth will the stock chain i have fit, or will i have to get a different one. and if i get a different chain what size wide will i need. i see that there is all kinds of different gear and chain sizes, like 11 wide and 13 wide and whatnot. all i want to do is drop a tooth on my top gear, so what size gear and chain will i need??
