The consumable parts on the SE/SP shock (seals, etc) are all identical to the Honda CBR600 F3, I believe.

If you want to revalve it, you could ask Matt from Tyga for the NSR F3 shock valve/shim setup and duplicate it on your own shock.

Alot of times, you can get away with jest refreshing them with new oil and a fresh charge in the cannister. You will need to fabricate your own service valve or buy an aftermarket end cap for your nitrogen cannister.

If you want to service the shock yourself, you can pick up a high-pressure bicycle shock pump to charge the shock. I picked up a Fox pump for about $20 from Ebay that pumps up to 200psi. Works awesome!!
