Sean - Like you, I found that with .85 or .9 springs, proper preloading, and 7wt oil - the front was quite good. I've wondered if playing with those two shims you could effect HS damping? I say for a lot street and some TD riders, springs and oil are all you'll ever need when coupled with a decent shock.
SPG, was this on the CUP bike or street bike? I think we all forget to be clear about which model we are talking about sometimes. I know both have different suspension on em.
Thanks,
Vaughn
Hi Matt,
Incorrect. It is the street bike. I have the cheapo, non-adjustable shock you have pictures. Only difference, is next to the top eye, I have drilled and tapped the body for a schrader valve which comes off at about a 45 degree angle to the shock. This allows for continued nitrogen draining and refilling. The first disassembly required drilling the top with a 1/16 hole (and safety glasses) to let the gas out. This hole was later enlarged to fit the valve. Once drained, the lower cap comes out with a drift punch, and the seal head is pushed in, and a circlip removed before it is drawn out with the shaft assembly.

True, it might not be for the average owner to rebuild. That said, if you were to take it to a suspension shop, they do this type of thing every day. Honestly the only reason I did it is to see how far I could take the stock suspension; now that I know, I'm glad I did

Photos and description of what you did, how you use it, and what it did for you would make a great thread of its own if you're so inclined.
36mm diameter x 250ish... The '09-'11 zx6r is supposed to be a match. anything from 230-320mm will probably be fine. If you shoot me a PM to remind me, I can try and dig up exactly what I did for the shims.
