its a common mod for the early model SV's. the stocky is puss, and wears very quickly. i read about it on another forum, and decided to give it a go. After hunting down a shock in the states, and getting it to aus, total cost was $156. to my door. i got up early today and dissasembled the bike. i took off the tail fairings, although its not really neccissary, to make access a bit easier. pulled the tail end down, seats, side vents, battery out, all of that. was a prick to get the stocker off, top mounting bolt wasn't too bad.. but the bottom! holy jeebus! now you only replace the shock itself, not the dig bones or knuckle, so what you have to do is undo one of the bolts at an end of the dogbone, swing the bones out of the way, and undo the bottom mount from the knuckle. good luck. to fit the new shock, you use the top bolt from the SV, and the bottom bolt from the ZX shock, so if the shock doesnt come with it, you'll need to get one. (the SV bolt is too short) then you have to file down the bolt head and the nut to get it to fit inside the bones when they are in place without it making contact. i also used a few washers to get the bolt to centre. cutting the batterybox id pretty much compulsory. there is a way you can move it back with spacers etc, but cutting is easier. you also have to remove the fusebox tray, and the battery holder attached to the front seat. once its all done, do up the nuts (try not to round them as i did tightening them. if the shock has to come off, it'll be a trip to a workshop i think) put your bike back together and away you go. ride report: fcukIN AWESOME!!! 500% over the stocker. sticks to the road soooo much better it isnt funny. holds lines much better. so much more confidence inspiring you wouldnt believe it only cost so little. it tips in better and easier, handles bumps like a dream, and gets rid of all the tramping the bike does when you take off and accellerate out of corners. it really is like buying a new bike. id have paid double that if i knew how much better it really was. if you are considering doing it, do it. im a happy man thats for sure. next thing ill do is the front end.. emulators, new oil and better springs. difficulty rating is about 3/5. its not overly hard with the right tools, just takes a bit of confidence, and muscle.
