For those of you that would like to install a XR400 oil cooler onto your XR600 or XR650L and don't want to weld nuts to your frame, here is what I did. I used the idea from the discontinued SRC mount and made my own. All you have to do is drill 4 1/4" holes into your steering stem and you can bolt the XR400 cooler directly to this bracket. Here is what it looks like... If anyone would like one of these brackets, send me a PM.
