DT400B twin shock - stuck piston ring was created by Jammyyammy

Hi - the lower piston ring on my 1975 DT400B twin shock is stuck in its groove at one end.
Before I do something stupid to free it, is there a trick?
I presume I just tease it out? And then clean any carbon build-up (I assume that is why it’s stuck)…
Thanks..

Apply something like WD40 or PB Blaster and let it soak in a few minutes.  You should be able to work it loose pretty easily.

Probably not 'very' stuck. I've given them a tap end on with a screw driver to pop free. Then again i've had to get serious on some 'really' stuck carbon'd in ones. Scroll this page below if ya want to see really stuck rings on my YG1T haha.
