So i went to the dealer they didnt have any case savers for the yz 450 however they had some really cheap that fit on yzf250's. So i bought the piece took it home and it fits the bolt mounts however the case saver didnt clear the chain enough. So i ground it down so that it clears and my question is how much clearence does the case saver have to have on the chain to be safe? Does it need to be the same as the stock flimsy one?? Thanks!
