I have an m01, with a13t sprocket. The conrod bearings feel really tight and the gear teeth look good. Good starter clutch. The clutch looks like it was abused with a punch or something but it works and has plenty of material on it. The ignition coil on the stator is corroded, it makes spark but needs replaced. Cylinder looks OK but there is no piston.
How is your m02? I could use a spare if it's decent. You can keep your stator if it's in better shape than mine.
