Am considering trying to add an oil cooler to my '86 while I have the motor out. Has anyone tried or heard of fitting a later model XR400 cooler? Don't really know the dimensions but read on Thumper Talk of one or two xl600 owners who have done it but gave no real description of how.
Wondering how much cooling it would provide as it don't look very big!
Read about using coolers from JC Whitney etc. but at 11" X 6" X 3/4" might be a mission to fit in.
Interesting discussion maybe?
