My Lev has started playing up on the last few rides. Whilst out it was not popping all the way back out, finishing just short if full extension. A little pull upwards and it clunked all the way up. I've just had a little spin out on the street this morning and it has a new issue, it's sinking 10-12mm when I sit on it. It didn't do this after my last ride when I cleaned it and wiped it with fork juice.
Is this something home serviceable or is it a case of sending it back? It's only maybe 6 months old.
