Alrighty..i picked myself up a spare Dohc zc for free because this kid ditched it for making a grinding sound..i suspected a spun bearing and i was correct. However, upon inspection, as i took off the lower pistion cap exposing the bearings, i noticed the bearings were shattered? they didnt just overlap..they were actualy in pieces.
This only happened on one piston and i searched a bit but found no info on this...
just curious if this has happened to anyone else?
