shock bleeding

Recommended Posts

I am having a problem with an oil change for a shock off of an 03' Rm125. When I try to bleed the stack, the nitrogen bladder keeps sucking itself down the chamber and then pushes back up causing the bleeding stage to be very difficult for me. I am fairly new to shock rebuilds but I have done a few in the past and never had this problem. Could I be skipping a stage or is there somthing wrong with the stacks that wont allow oil to flow and bleed out the air. Any help would be much appreciated!

the only thing I can think of is to fill the bladder hole about half way install bladder and circlip inflate with air to 25-30psi this pushes all air out of adjuster into shock body then with all of your clickers backed off fill the body to about 1-2 inches from the top and install rod and shims then bleed from there. Hope that helps I would just start over with this sequence if you are having problems. :thumbsup:

Sounds like your not inflating the bladder prior to the bleed proceedure.

Also make sure your rebound needle is backed off, if its not this can create a vacum on the back side of the piston. Depending on the amount of air that you are putting in the bladder it can suck the bladder & cap inward.

      Hi,
      I have a 2003 DRZ (actually a KLX400) and the head tube bearings are shot.  I ordered a new set to install but I'm wondering if anyone has any recommendations on other parts I should replace while I have the front disassembled.  I was thinking about new rubber fork protectors, but are there other things that wear out on the DRZ front ends that you can only get to when disassambled?
      I also broke off a replacement key that I got for the steering lock.  I must have been made of cheap pot-metal.  Should I just remove the whole lock mechanism?
      Any tips or tricks for getting the old bearings out and the new ones in would be welcome!
      Thanks!

      Hey guys. I recently purchased a 16 yz250x and the first 2 rides i LOVED the suspension. Then the day before a race i reset all my clickers to stock and everything felt like crap. No plushness at all and deflected off everything. I now have a 5.4 shock spring for my 190 pound weight and dialed in sag. Any recommendations on where i should go from here? Right now the fork is 12 out on comp and 15 out on rebound. Shock is 1.75 turns out on hsc, 14 out on lsc, and 18 out on rebound. Any help would be appreciated!

      Today we’re going to be talking a little bit about automotive suspensions and how they work to smoothen the ride of your car. There are mainly three purposes of the automotive suspension system. First, they support the  weight of the vehicle. Second, they maintain accurate tire contact with the ground. And third, they absorb any shock that you get through the road when you hit a bump.
      Most modern vehicles come with an independent front suspension. Which means if one wheel hits a bump it does not disturb the other wheel. Nowadays, people use Coil Spring to support the majority of weight in the car. As it has a really good characteristics for absorbing any bumps as you go up and down on the road.
      However Springs aren’t very good at dissipating that energy. In fact that’s why you have the shock absorber. Which is there to smoothen out the ride and make sure the tire maintains contact with the road.
      In modern passenger vehicles the two most popular suspensions are McPherson strut and double wishbone style of suspension. The main advantage of the McPherson strut suspension is that it’s really cheap and simple that’s why a lot of manufacturers are moving towards this design. The double wishbone design allows the wheel to stay perpendicular to the body as it navigates a corner or as it goes over a bump. And that maintains good tire contact patch no matter where the wheel is situated. Another advantage of this design is that it can be made adjustable where you can control the position of upper control arms ball Joints.
