I rebuilt my front shock for the first time. Its an older oil cartridge system. I used instead of the stock 7.5 wt, a 10 wt fork oil. It has such poor responce. It stoped bottoming out but is taking to long to rebound. The recomendation was to replace the cartridge, ... I didnt do that. How do I know that they are even bad? and is the 10 wt. just to thick?
