Title: why is my rebult shock so soft?
Post by: turtle22 on June 06, 2009, 08:33:51 AM
so i just replaced the seal head in my shock. changed the oil and recharged it,yet it is super soft and springy. i adjusted the clickers(there almost all the way tight). we adjusted the sag of the spring. what should i look for or do next?

What psi of nitrogen do you have it set at, how much oil, what kind.  These will help diagnose the problem.

sounds like some debris stuck between valve stack. If you go in on compression 3-4 clicks you should be able to feel a considerable difference just by pressing down on the seat.?.? If hardly any difference I would assume trash between a shim or shims holding the valve stack open which will cause little or no damping.

first off 250 psi is to much nitrogen pressure, should be in the 150 to 190 range, having said that you have other problems I'm thinking maybe you didn't get all the air bled out of the shock and bladder. To much psi usually makes it stiffer.

If ANY air is left in the shock during the service, Very Bad things can happen. Ex Local Pro rider did an oil change himself (brought it to the shop for Nitrogen) and went to the races that weekend. He did not get all of the air out & after about 10 laps the bladder cap was blown off from the air being heated up. It destroyed the shock, & luckily no one was hurt.
