As I said, you may never get found out for doing it. But is it a risk worth taking? only you can decide that, it's your bike not mine
So what happens then if you buy a used bike, and like many people on here have very little mechanical knowledge and dont bother to check how many teeth are on the front and rear sprockets compaired to the manufactures spec. But the previous owner has changed the sprocket but not told you, as far as they are concerned its still manufactures spec, what happens then???
