Default 2000 yz125 suspension problem?

the suspension in the rear of the bike compresses when landing on jumps but does not return to normal height after leveling out. What is causing this? Do i need a new spring?

yes you do need a new spring, and probably a stronger one if you are going to be doing jumps. The cause of it is your jumps. Eventually the spring gets worn, and it won't return to the original height. You want to change the spring before it gives out completely and then you have serious problems

ok here we go again...springs DO NOT wear out ot give out or whatever...they can be too stiff or too soft for your weight, but they dont"give out", period...the rear shock controls the action of the spring by"damping"its actions so you dont just"pogo"around on a spring...the shock is where your problem lies if the bike compresses but doesnt return...go to a suspension shop and they can revalve it and your problem will be solved.oh, and they will also tell you what size spring is right for your weight and ability, and confirm my assertions about a spring giving out...good luck :o)look if you want to get technical an old spring might lose 1/2 inch in height after YEARS of use, but thats not this guys problem ------

Springs, like anything else DO WEAR OUT and become shorter with age although the actual rate doesn't change muchIn your case though, I would guess someone has let nitrogen out of rear shock so there is nothing to push damper oil back into body of shock. If the seal was worn out and you lost all the oil it would over react. ------

Yes a spring will wear some but not enough to cause what is happening to you. You have a blown shock and it needs to be rebuilt. This is not something you want to try yourself. These guys are the best.http://www.factoryconnection.com/services.htm ------
