To replace the fork springs do I need to remove the fork tubes from the bike or can I leave them on? The manual says to do this and that but I am not doing a complete rebuild. All I want to do is put in some heavier springs and maybe add oil if needed. It seems as if you need to measure the oil with the springs out and the forks completely compressed. I guess if i want to add oil to a certain level then I will need to get those fork tubes level, so I think that answers that question. BUt if I just want to add 10 ml to each side I wouldn't think that being level would matter. What do you think?
