CB500/550 / Re: 1975 CB500K1 crank rotation resistance
« on: May 03, 2024, 12:19:35 PM »When you assembled the crankcase halves is it possible that an excess of Hondabond could have entered somewhere to lead to this problem? Could the crank seals be somehow causing the extra binding if they have distorted?
I'm assuming you have not fitted the block yet.
I think you will have to split the cases again to investigate further.
I have considered if the seals were the problem, but fitted well and tightening only happens on final torque of mains bolts.
I will try easing them off and re torquing.
You can turn the crank but do need a spanner on the alternator bolt.
Wondering if I am being too cautious.
Can you normally turn by hand on rotor without pistons fitted?
