i was the first to post on this back in the day, i did it very easily. You have to press out the zx10 stearing stem and the 636 stem then press 636 stem into zx10 bottom tripple, the top tripple on 636 is fine but bottom needs the zx10 tripple, forks are bigger. after that i mounted entire zx10 front end on, forks, cals, rotors, wheel were all together at that point, lowered bike about an inch, all in all a good way to go i guess, but i never really see the reason if you keep checkin your equipment the 03 04 dont have a mass failure, just a few incidents.
