its not to bad a job to do first make sure you have got bike propped up under the engine remove front wheel then try and remove mudguard,loosen pinch bolts on side of yokes and slide forks legs out.remove dust cap on each fork and remove circlip holding seal in. once you have done that turn fork leg up side down and you will see allen bolt in bottom of fork leg undo that and then slide forks apart once allen bolt is out the oil will pour out of the hole so be ready to catch it.you can then use the top tube of the fork as a drift to remove old seal.once out slide it off bottom of fork tube andclean area up in top of fork.you wil have to gently drift new seal into place,then slide fork tube back in untill it hits the bottom and replace the allen bolts.then remove top cap of fork leg and put in correct amount of oil,once done put top caps back on and rebuild front end
