you have to use aluminum. 83-85 is most popular for stock gearing.

most peopl will use a 35T or a 40T. you can switch from 12T front 13T or 14T.

1 tooth up or down up front is the same as 3 teeth up or down in the back.

i think that a 250r sprocket is the same bolt pattern.. the trx uses a 38t rear.. i cud be wrong, but im almost positive theyre the same bolt pattern..
