I recently bought some manitou 4s to fit on my rts-1. I've ordered some springs to replace the elastomers (shame really as all but 2 were good), but after dismantling and rebuilding, noticed some play when the lowers were pulled back and forth. I also noticed that the crown also had a crack in that you could see daylight through. Luckily I had also bought a set of manitou comps (for another build), so could use the crown from this, but fear that the play is caused by the wear on the slider. Ultimately this post is for advice on if/how I can prevent the play, as ideally I would want to be able to ride these forks once fitted, so anyone got any ideas, or spares (stantion/bushes?).
