I ride a ProFlex 856 that I love. Here's the Q...The shock is a Girvin ODS/coil spring. The damping ability was originally intended for the elastomers that ProFlex used on some models. I have had the shock apart and changed the oil with the only weight I had...15w, versus the 30w (I think) that was in it. I kinda knew that it was too thin, but that leads me to why I am posting this. Does anyone know enuff about suspension damping to recommend a way to 'beef up' the damping, providing me with more damping abilities? By the way, I have two of these shocks, so if I tinker with one, I still have a good one that works. The cheapest way would be to greaten the weight of oil, but why spend $15 on a quart of shock oil I'll never use if it doesn't work.
