Can you frok up a fork. . .

By putting to many pounds in it? What I mean is will putting more PSI make it more likely to "blow"? I found that I prefer to have my fork a bit stiffer (I'm talking around 15-20 PSI, not 100) than recommended. Or is this not an issue if your LBDs are still intact. But in all seriousness I'm not hurting anything am I?

What frok?

I called Zokey and they said I'd be okay with possibly even up to 50 psi in my 55r which is only rated from 5-20.

Grain of salt.

My son has a 2008 Marz DJ 1 - a week after he had it he put 60 psi in the fork, an hour later there was a large puddle of oil under it. We ended up putting new seals in it because it would not stop leaking after that.

Oh - and there was a small nick in the left lower LBD.

Is this a trick question?

Unless you already have the PSI maxed out, a bit more over whatever is suggested for you shouldn't be any problem.

Example: I'm running 10-20psi over suggested for my weight on all three of my air forks to get them to feel how I want. Yet I'm still way below the max suggested. I'm sure I could run all three up to max without issue, other than not being able to get any of them to move.

I was actually referring to the "max suggested" with regard to my frok. My 55r is coil/air-assist. The assist side is rated from 5-20psi. I called Marz and they said "Yes, it's only rated to 20psi, but it should take up to 50psi with no issues."

What I took from this was that maybe the assist cartridge is similar or possibly the same as the air only 55 which takes much more pressure than 20psi. I just have most of my preload handled with a coil instead of air only.


Thoughts?

I realize after reading what I wrote that it doesn't make sense. Heres what I mean. You know when you blow up a balloon a lot, its fairly easy to pop. Does something similar happen for forks?

I'm going to hijack my own thread. When I run the PSI that feels best (just under a hundred, even though fox recommends 70-80 for my weight) I haven't got any sag (well, 5mm worth of 130mm). I'd guess I'll be missing that sag once I hit the trails again (tomorrow, I hope)

Yeah, that sounds fairly uncomfortable. I only run about 25% sag. Less than that and you start defeating some of the purpose of having suspension in the first place.

I guess if you just want the fork to take the edge off larger and harder hits, and not worry about the small stuff or helping with maintaining traction or anything. . .

Well, the thing is, I bottom like crazy if I have more than 20% sag. I dont know why this slipped my mind, though. Tomorrow, I'll mess around with the low speed compression. Although, even with the 5 or less% of sag, this fork still feels SOOOO much better than my old one. I think I'll also just start riding at two different PSI settings. One for trail riding, another for urban riding and bigger hit stuff.

Yeah, but with the Pitch...you're running about 45% sag

I usually do around 30-35%

Whenever I run the fork with the correct sag, I feel like the repeated bottoming is going to hurt it. Keep in mind with 30% sag, I'm bottoming when I the front brake hard.

If you have your sag get correct I think your barking up the wrong tree. You need to get the sag correct, then play with your compression and rebound settings I believe that is where your problem lies.

Do you have a zip-tie wrapped around the slide part of the fork tube??

Yeah, I've got a zip tie, the only problem is even when I've got my talas's compression as stiff as I can get it (key here is "I") it still bottoms justs much. I think I'm going to run the fork at higher PSI and try making the compression softer tomorrow.

Does the fork have rebound (Im not totally familiar with it), If your rebound is too tight it can cause the fork to pack up and eventually bottom out.

Possibility theres something wrong with the internals???

Just throwing out suggestions!

I really dont think anything is wrong with the fork, and the rebound is right at midway. I think its just me. Am I hurting the fork by bottoming? Could an oil change help with this?

If you change the oil to a 10 weight it will slow down the rebound and compression - and potentially reduce bottoming.

What fork ar you running - I've had 3 foxes - 2004 f100 - 2005 36 RC2 - and a 2009 32 TALAS w 15mm axle - the only one I had bottoming problems with was the 36 (I was told there was a factory only bottom out adjustment - but I never had it changed) - I changed the oil to 10 and fiddled with both compression adjustments and the problem went away - I weigh 150#

Its an 06 Talas (32) RLC. Change it to a heavier oil your saying would help, you say? That would make sense. It might also be due to the fact that its not degrees (F) out side. Just heard the coldest point in the US right now is the next county over.
