CB500/550 / Re: 1975 CB500K1 crank rotation resistance
« on: May 08, 2024, 11:06:16 AM »
Its apart again.
Checked crankcases for distortion and found that approx 6 thou out at no.1 main journal housing face of upper case.
There is a lever mark on the inside face of alternator rotor and had not been removed by PO.
It came off fine with threaded bar screwed in to end.
Wondering if PO levered a bit too hard on case.
I am also going to check the mains run out with V blocks and surface plate.
Any experience of crankcase face distortion?
