I have a question: I'm not a mechanic, but I've trying to fix my bike little by little. I use to travel alone, but when last time I went to the market with my girlfriend and I noticed the rear suspension went really low. I was adjusting the shock and I noticed a valve on top of it. A friend of mine told me these bikes use gas, and probably that was my problem (out of it). Is it true? what type of gas does it use? do I have to take it to the shop or can I do it myself?

I think someone spoke about this but I can't remember who. All I found was this thread from Forchetto, the valve would be the #9 http://www.mychinamoto.com/forums/sh...ght=suspension
