I have a Kawasaki FH601V twin that was dumping oil out the top due to a worn crank and journal. I replaced the crank with a good used one, new bushing, rings and seals/gaskets. It ran great for an hour with small oil leak at the top again because I did not get the oil seal installed correctly. I noticed the crank is hard to rotate (can't rotate by hand) as I was installing the new oil seal and setting the ignition. I removed the spark plugs and it is still difficult to rotate. I readjusted the valves but it made no difference. It appears to be most difficult to turn at the bottom of the stroke on cylinder 2.
Do I need to tear into it again and if so what should I be looking for?
Thanks!
