do you still have the piston kit? how much is it? I think it will fit my xl500r. are you sure about the bore size? (89mm was standard)

in 1983 the radial 4 valve head came out. the xr was a 500cc but the xl was a 600. i doubt very much it will fit

There are to many differences for it to work in earlier XL.

Pin is different, bore and stroke so the piston top to pin will also be different.
