i have suzuki part number 51553-27g00 and 51173-27g00 they are the fork oil seal and fork dust covers. they are for a k4 gsxr 750/600 and they dont work, the old seal have an out side diameter of 56mm and the new seal are 54mm, the forks are stock wtf happened. I need some serious help, does anyone made aftermarket seals? the part numbers are correct but the seals and dust covers are just too small. help please.
