Name that engine part...
Hello, (long time/no post and all that...)
Carried out an internal engine inspection today (Wednesdays are really boring) and have come accross a part on the clutch side that I cannot identify. My bike is (still) a 125cc Derbi.
The object in question is the circular piece just east of the clutch assembly, and just north of the yellow gear. Its cover was a metal plate with three screws and some kind of spring loaded pin. Photo below;
does anyone have any idea what it is? It sems to be on the crankshaft and it roates with it too. Any help would be much appreciated.
