Subj : engine stuck To : All From : Pork Date : Tue Sep 14 2021 16:08:38 I think this will qualify for DIY. I have an old 1991 Honda CR125 dirtbike that I found in a barn. It has been sitting there for at least 20 years. Other than being very dusty, the engine is stuck. I have pulled the spark plug and dumped Marvel Mystery Oil in it to let it soak. So far it is still stuck tight. Any DIY potions you guys use to unstick a piston from the bore? --- * Origin: The Lab BBS D'Bridge/Maximus2 Old School OS/2 (21:3/105.1) .
