I think I will tear the one apart that is shot so I can experiment with it. As far as it being refilled with Nitrogen, do you have suggestions on where I could take it to have this done or would I need to buy equipment?

Thanks

You would need to buy equipment unless you happen to know a shop with shock equipment or if you had a buddy with a nitrogen tank, you could rig something up.

Some shops will do it for a fee if that service is available. Evan also sells the equipment for you to do it yourself. I was surprised to see that its pretty affordable. On the other hand and I know many will have different opinions, but I have heard of people using plain old air. Most of us are weekend riders and not sponsored supercross riders so I don't think its 100% nessary if your doing this all yourself.

Like I said others will have a different opinions. If you doing it yourself on a joy ride bike why not? I'll give it a shot one of these days. Worst case I'll perge the air and recharge with the correct gas.

Air expands with heat,and should not be used.No offence to anyone who thinks otherwise.If you do start work on one of them make sure you release nitrogen pressure first.a lot if tire places are using nitrogen to fill tires with ,but I don't know what pressures they can go up to

Agree ^^^^. Don't use air. I also thought of the nitrogen that tire places are using but I doubt they go high enough as vehicle tires only hold up to 65psi tires pressure max and oem shocks need 200psi.

You will need to completely disassemble the shock to get the bumper replaced.. as stated earlier, when the shaft assembly is out of the shock,you will see where the factory "peened" the shaft nut on . This peening needs to be partialy removed to get the nut off and be able to disassemble. However you must be careful to not remove too much, as the inner part holds the rebound assembly into the shaft center core.. I do sell individual seal kits and parts, as well as nitrogen tools for the DIY guys.. however if you've never done it before, the package price on ebay is hard to beat. Also, one of the extra and unadvertised extra for all trx and ATC 250r guys; is that they also get the lower spring retaining ring,C-clip and bumper-cup powdercoated silver.. I have built up a pile of those parts over the years , and have batches of them done, so for all the "r" guys who have supported us, they get a little extra bonus..Plus we do little extra's that many shops don't. Look at at the break down pics for a rebuild by us on ebay. And yes nitrogen in shocks, not air.. Air contains H2O which is corrosive in a confined space for a prolonged time, and also as states expands like crazy with heat(steam).. so no bueno.. Evan @ SRS
