Just got bored and tore down a known worn rear FL350 shock. Not a drop of oil in it...this does not look like a gas charged shock. No internal floating piston or separate gas chamber at all. It is possible to try to rebuild this shock...if it is a fluid only shock. Has anyone tried this before...finding a seal head...and a good fluid capacity and type? Honda manual obviously has nothing about rebuilding shocks on the 350.
