Fasst Flexx Bar Noise

I purchased a used set of Fasst Flexx bars. I installed them, and they squeak like metal on metal something terrible. I removed the elastomers, and have soaked them with penetrating oil, as well as silicone, with no success. I pulled the snap rings off, but am unable to get the center pins out. Is this normal? I tried everything short of a hydraulic press to get them out, which I don't have. Is there any way to quiet them? Can you drill a hole an install a grease zerk?

I got a set second hand, the pins were seized and would not flex, I had to apply slight heat and press the pins out with a vise, took abit but they did come out. The pins were rusted and I cleaned it with a wire wheel, greased them and re installed and they have been fine since. I rebuild them every 20 hours or so to prevent this happerning. Be carfull with the heat as there is about 3 o rings on the pin that can be damaged. Another tip is to get some more elastomers and longer bolts, the extra go on the outside for pulling up, I run blue on the inside and yellow on the outside, faast sell these as a rebound kit.

They can take a press to get them out if they have been in for a while. But they just need disassembled and greased. If you do that about every 15 hours or so they come apart real easy. But the extra rubbers on the outside to pull up is a nifty trick that a lot of people use. It dampens to reflex on the bars and helps.

Thanks for the replies, I did not know that about adding extra elastomers. I would love to see pics if you get a chance. I don't think I have any O-rings left, might be time to get down right nasty with them to get them out.

Flexx handlebars by Fasst Co... A Review. - ADVrider

this is all the kit is

Fasst Flexx Rebound Elastomer Kit | Slavens Racing 719-475-2624

you can get new seals from faast, i think there is also a video on how to rebuild, its just a guy hitting the pins out with a brass punch with the bars on the bike
