My pk 100s engine has play in the crank as shown in the image below of around 1.5mm either side ,is this normal or should I replace crank (I suppose the bearing is very hard to replace),also my clutch basket has play around the primary drive axle ,when applying pressure to clutch basket it shifts side to side about 0.2mm around the primary drive axle as displayed in image below. Any advise would help as these are very specific and hard to find answers about.
