The bike is a 2006 ZX-10R, it is a race-only bike for me.
The forks have the 25mm Ohlins cartridge kits installed.
It appears the forks were re-valved by Thermosman.
I have been playing around with suspension settings trying to get the front-end sorted out, and when I pump the front suspension, it does not return up all the way. I have to pull it up. If I do pull it up, I can push it back down again and have it stay there. It looks like MAJOR stiction, like well over an inch and a half. Another example was having it ratcheted down in the back of my truck. When I released the tie-downs, the bike didn't come back up until I pulled on the handle-bars.
Messing with the rebound, if I turn it up to anything other than the last few clicks, the front effectively becomes a solid suspension that won't budge no matter how hard I try. So, I run it 2 clicks in from fully out to make it rideable. Weird thing there too, there is a different amount of available clicks between the left and right.
So, I plan on opening up the forks this weekend to give them a good cleaning, change-out the fluid, and make sure the fluid level is set correctly. What I'm looking for is any advice on things to check while I'm doing this that could cause this condition? Is it possible that the forks are just valved to where I should be running them with the rebound adjusters fully out? I personally would like to have more usable adjustability for different tracks.
