Dillyboy, I've got an 81 GS750E that's getting the same treatment. I've got an 88 GSXR750 front end (not an upside down fork but fully adjustable nonetheless) and since I foolishly tossed the original forks I don't know what the length is supposed to be. Would you be so kind as to measure from the top of the fork tube to the center of the axle bore of the sliders for me? Thanks.
Bernie
