So I've been having some bottoming out/clunking issues with my front forks and when I check the travel on them, they only measured to around 124mm when spec is apparently closer to 137mm. However, apparently these forks are non-adjustable so what can I do to get these forks back within spec, and not bottom out anymore? Does it not have enough oil? Too much? I really don't know as I'm a complete novice here, but I'd appreciate some advice!
