mopar1rules Posted August 26, 2008 Report Share Posted August 26, 2008 the stock rear shock on my '98 shee, is in dire need of a rebuild. i never rebuilt a shock before, but am going to atempt it. i have a haynes manual, and it doesn't say anywhere about how to rebuild the rear shock, so i'm going to ask you guys. do any of you know how to do it? have any of you done it before, or even found a better setup than stock? i weigh 140lbs and just play around in fields for the most part, but am planning on playing around on a friends track, so jumping is in the future. so, if anyone knows the step by step procedure, can you please pass it my way? also, this topic might be a good one to turn into a sticky, for the folks in the future that want to rebuild their stock rear shock.

Bansh-eman Posted August 26, 2008 Report Share Posted August 26, 2008 i havent evern taken apart a stock shock before , but for some reaso i want to say it uses concaved diskes that you stack opposite of each other and it controls the "valving" but i could be thinking of a differant shock. As long as you have the right tools, the oil and some nitrogen to fill it up when your done, im sure you could figure it out Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted August 27, 2008 Report Share Posted August 27, 2008 Rebuilding a stock shock is a pice of cake. You unbolt it. Drop it in a cardboard box and send it to elka, works, Tcs, Pep. Couple of weeks later it shows back up. The aftermaket companys will valve and spring the stock shock for your weight, swing arm length, and riding style. Much better than just thowing new yamaha parts in there. Quote Link to comment Share on other sites More sharing options...
mopar1rules Posted August 27, 2008 Author Report Share Posted August 27, 2008 (edited) one of my buddies who does shocks, is going to help me, but he said he needs to know what the piston or float height (i think that's what he said) gets set at and how much psi of nitrogen we put in this thing. does anyone know this? jbooker82, yeah that would be an easy route, but would hurt my shallow pocket book, and then there wouldn't be a learning experience involved :smile: Edited August 27, 2008 by mopar1rules Quote Link to comment Share on other sites More sharing options...
Bansh-eman Posted August 27, 2008 Report Share Posted August 27, 2008 the pressure depends on the valving and what type of riding. When i had mine rebuilt it was set to like 600 psi. However that wasnt a stocker so the valving wont be the same. Just pump around 600 in it and try it out, you can always adjust the pressure to your likeing after you rebuild it Quote Link to comment Share on other sites More sharing options...
LiftdT4R Posted August 27, 2008 Report Share Posted August 27, 2008 If you do a search around here there was somebody that posted directions for doing it. Be forewarened it's not simple. As I remember Yamaha doesn't make the shock completely rebuildable. When you send it out to Elka, Works, TCS, they put a lot of new parts into it to change the valving, etc. I don't remember what's all done, but for the $400 TCS charged to rebuild/respring mine it was well well worth it, they have their shit down to a science.

I do concur. A buddy sent his wifes 400ex shocks to TCS and had them redone, that thing rides like a sand caddy Quote Link to comment Share on other sites More sharing options...
LiftdT4R Posted August 27, 2008 Report Share Posted August 27, 2008 Hell yeah, I love mine, they put dual rate springs in there and valved it to match my Elkas up front. If you just want to have them rebuild it and reuse the stock spring, and dont want anything fancy I believe it was less then $300. Quote Link to comment Share on other sites More sharing options...
