How to improve suspensions "bouncyness"

CharlieV453

Hi there,
My friend recently bought a new fork (rock shox sector gold 140mm) and I had a quick go on it. Quickly I started to notice a difference in how much more quickly the fork returned and how bouncy/springy it felt. I am running my rebound as fast as possible I think and have tried a few different pressures between 60 and 80 psi. My forks are a similar level I believe with the same sort of coating and length of travel (I have a 130mm manitou minute comp with replaced CSU that came on my Ragley Marley 1.0 2017). Does anybody know a way to improve the rebound speed of the fork for a poppier feel. If possible it would be a way that didn't require me to take the fork apart as I don't have massive amounts of cash or mechanical expertise.

Any help is much appreciated
Thanks

Are you sure you have the rebound on your fastest setting?

I ask because I checked a friends bike, and he though more rebound was faster. Rebound is a damper setting so needs to be dialed off, his were set on max/slowest rebound.

If you only think the rebound is as fast as possible.....then check and be sure! I've lost count of the number of times people turn it the wrong way.

Yes I am 150% sure it is on the fastest setting. The fork says so and I can feel a much slower return speed when it turns the other way

Without possibly rebuilding the innards, that's it then.

Really. Is there nothing else I can do whatsoever?

Not that I know of. Damping is a cartridge, so all you can do is replace it, or take it apart, but that's technical.

But extreme bouncy isn't necessarily good. It needs to be controlled.

I'm not looking for it to be uncontrollably bouncy only for it to give me a little more pop. Would decreasing the friction on the stantions make it return a bit faster at all?

I think he’s just got a better fork than you, time for an upgrade!

As I said they are almost the exact same price and I don't have the money to spend on a new fork. ☹️

How heavy are you? 60-80psi seems quite low pressure?

Damping is generally achieved by having a piston push (or pull) suspension fluid through a small orifice.

You'd need to take the damper out and change the orifice size but unless you know what you are doing there is a risk of messing up the forks.

Changing the viscosity of the suspension fluid may change the damping characteristics.

I'm around 70 kilos and the shop I bought my bike from said that 80 psi was a normal but on the harder side for what I should be running. I don't run as low as sixty I was just playing around to see if I could get the feel I was looking for.

Ok I may try that when I get my oil changed next. I'm not sure if this had anything to do with the problem but it only started when the cold kicked in so that could be part of it maybe.
