I am gonna buy a new chain, front sprocket, and rear sprocket for my 1989 YZ 125. The only problem is, i dont know what to get yet, what chain would i get, how do i know how big i need it?? And about the sprockets, do you get more power with the more teeth your sprocket has or is it the other way around. someone please help me out.
