I just got a new LF 200 the other day, and I already love it, but the vibration in the frame that I have heard about is really annoying. What sort of things can be done to dampen this? I have heard that putting rubber rings on the engine mounts and getting gel grips help, but does anyone know what rings fit on the mounts? also, does anyone suggest a certain kind of hand grip that works well for them. thanks.
