i have been using a marzocchi z3 flylight for about 2 years now and it has performed fairly well. But I have heard that changing the fork to coil springs really makes a big difference. So I bought a pair of 100mm springs...the springs seemed to fit very nicely and I was using the stock air caps. My problem is that every time I compress the fork I hear a slight rubbing noise from the inside of the fork...apparently from the springs rubbing something on the inside. I was wondering if anyone has had problems like this and/or if this will damage the fork or if it is ok. I don't really mind the sound...on the trails I won't even be able to hear it. I am just worried that I will be stripping down something on the inside. I have also heard that you can put some shrink wrap around the springs to quiet 'em down. Anyone have any ideas on this?
