I've just had my fork seals done and when I got the bike back from the shop it felt absolutely horrible! I set about adjusting the suspension (1st time I've done this) to the manual's recommended settings as a starting point.

I changed the pre-load and rebound no problems at all (top of fork), however when adjusting the compression the right fork leg seemed to work flawlessly, as per the bikes manual, but I could not get the let fork screw to lock out - no matter how many clockwise turns I made.

Am I doing it wrong? - is it knackered? - has the bike shop not set it up correctly?

Additionally - do the settings have to be identical on each fork - or will I cause damage by riding it?

As always any help is greatly appreciated!
