La soupape d'échappement reste ouverte.
Un problème courant avec les moteurs Motobecane S Bloc utilisés dans les modèles de motoculteur Energic C7 et D9.
Remove the valve cover by unscrewing by hand the ridged oversize outer screw head. (check the seal). Les originaux étaient à base de liège, mais un nouveau matériau moderne peut être utilisé.

Just un cease the valve stem, by working right to left with WD40 or other release penetration agents. Could use penetration oil gently tap spring pin stop from right to left and back again.

Shimmy discs can be used to pack worn valve stem bases. Also to aid compression and timing. Gardant ainsi la tige de soupape en contact avec la tige de poussée à tout moment.
Removing the valves, and re-seating after grinding the engine head surface, will give a better tight fit to the valve and aid compression. The De-coke!
