I have 3 boys, two of them are riding now and I know the third is ripping to go. My oldest is on a RM 85 and my middle one is on a cobra. I had suspension work done by some good people here in central Pa but, wow it was not cheap. I will have 3 boys racing and all needing suspension work done from time to time and that will add up to be WAY too much. I have checked out prices of RaceTech gold valves and parts and if I could do it myslef i know i could save a BOAT load of cash. What are some suggestions and where can i learn how to do this on my own? Mind you Im not a rocket scientist but, I am smart enough to come on here and ask for help!
