joe: as with anything else in life they're fairly straight-forward if you have someone walk you thru it or assist you. you'll need 1 pint per fork of quality fork oil like bel-ray with seal swell. i prefer 7.5 wt but think manual calls for 10wt. depending on your mileage you should also replace the inner and outer slider bushings along with the seals. it always seems to be the right seal that leaks first. i attribute it to brake dust on that side and not the left side. you can also consider removing the entire 2 fork assemblies yourself and taking them along with the bushings and seals to local shop that can do them for you. OR send me email if you decide to do it yourself and i'll walk you thru it. you can use store-bought seal driver, handbuilt seal driver made out of pvc pipe, or punch and hammer if you have patience and some dexterity. and on the seals the moulded in writing on the seals goes towards atmosphere. hope that helps. email: scootertrash196@yahoo.com
