mine is an isri and there were zero parts avail for it and it is VERY complicated. after richard and i both spending hours trying to fix it. (mine would give a roller coaster ride, going full up and then back down), richard then just did what he did to his. i have a manual air valve that inflate and deflates on my command. works great and is simple. but, the seat does not float down like when it has no weight on it like it originally did
