Anyone have any tips on how to loosen the hose clamp for the crankcase ventilation hose on a 91 K100RS? Can't access with a screwdriver and not having any luck with a 7mm socket, which I can barely get on it. Be interested in hearing what type of tools folks have used to get to it. It is located on the left side of the bike, just aft of the rear air intake tube, underneath the relay box. Thanks...
