I am  doing the main seal on a '92 K1100LT. 

With the clutch carrier out, how much movement should be seen on the output shaft? 

I can't seem to find any figure for the k1100 in the clymer

Not sure why you'd measure axial/end float with the clutch housing removed: the front bearing of the output shaft (just behind the oil pump) is a needle roller and floats axially whereas the big back bearing is the one to provide axial location - so long as the clutch housing is installed and tightened up.

Obviously the output shaft will float all over the place radially, without the clutch housing installed. Always worries me  Shocked.

The early 2v Ks did have a problem with output shaft axial/end float because the big rear bearing was insufficiently located in the crankcase. The bearing was replaced with a shouldered type to prevent this. The symptom was a variation in the clutch biting point; as the output shaft floated backwards and forwards in use.

Same here that's what had me thinking about it but you've reassured me Suzi Q. Thanks
