Default Yz125 Rear Shock

     

Hi guys I would like to know what to do with my rear shock on my yz125.
When I sit on it, it takes a while to come back up.....I think that my rear shock is a gas shock because it has a little reservoir beside it. Do I have to bring it to my local bike shop and ask him to put more gas in it? Anyways please tell me what I could do to solve this problem.

it sounds like rebound is the problem, i think you can adjust that on some shocks, im not sure how though, try looking in the manual

The first thing you need to do is make sure the rebound adjuster isn't cranked in too far (that's the one on the bottom of the shock near the linkage).

If that isn't the case, I would be willing to bet that you have never greased your linkage or swingarm pivot bearings, and now one or more of the bearings has seized. Pull the linkage apart and remove the swimgarm. Clean all of the bearings. Replace any that are worn. Grease them liberally, and re-assemble. I'll bet your sticking rear-end (the bike's that is, I hope yours isn't sticky )) will be fixed.

FYI-the nitrogen is not what makes the shock return to fully extended. That is the function of the spring. All the nitrogen does is keep the oil under constant pressure so it doesn't foam up as it's being repeatedly forced through the valving.

Ditto What chokey said.

Check your rebound setting first.
Grease your linkage no matter what.
While the shock is out, It's probably long over due to be serviced. Find a local suspension guru and have it rebuilt. Or send it out and have it done. Seal Head, piston bushing, oil, nitro and Labor should be about $100-120

Good luck

Ian
