Have some ongoing experiment to see if I can improve the FS shocks.     A short video clip of 'bench testing'  View My VideoThe idea is t prevent cavitation in the dampers by using a very small bleeding hole out to the volume compensation chamber, so the oil can't escape anywhere fast when cavitation occurs. Well, that is my theory, still have no idea if it works in practice. |

Saved some money, but it's definitely time consuming, and still not verified to work  I'm not sure there will be a visible difference.. (compared to recently serviced standard shocks). The difference would probably be on a extremely rough surface and hard landings. My hope is that this will make the shocks more reliable. The way it is setup now, it should also self bleed air out of the shock to the top of the rubber 'chamber'. Then the idea is that I would only need to fill some oil in the chamber once in a while.. As it has been up to now, I had the shocks apart every second tank or so, because of problems with the silicone 'bubbles' not staying in place, clips, leaks etc. It seems the welded washers hold up well. The next weak point actually seems to be the plastic 'piston', I bent one when I tried to make the dampers (too) hard. I have also tried 'foam washers' instead of the silicone bubbles, and that worked ok for a while, until the foam got hard from the synthetic oil I'm using.. Now I'm back to a little softer setting on the damping, so that might allow it to bottom out in jumps too. Will see if the weather allows a test drive and some filming today. |

Yes, I can confirm that the experiment failed..
One of the bellows was full of air like a ballon, and the other one had cracked, from overpressure I guess..
Seems the shocks are sucking in air through the shaft seals and the pressure then rises..
