I recently bought a set ( secondhand) and for the life of me can't work out how to adjust them. The front ones look like they may need a tool to turn the top sleeve in or out (havn't tried yet) but the rear ones look like the are welded like a normal shock. And before anyone asks they both have" adjustable" stamped on them. they are Red fronts # 80 2156sp1 and the rear are yellow #80 2299sport
Am I missing something?
Help please.
