Hi all. New member here, but I have read the posts for years. I have a 2013 cb1100 that I bought new. The bike has 1600 miles on it and I pulled it out a couple days ago to go for a ride and the engine started making a knocking noise from the lower end on the right side. I shut it off and decided I should change the oil before I really start freaking out. Drained the oil and it was full of glitter, likely aluminum from the crank bearings I'm guessing since it didnt stick to a magnet. Changed the filter and fresh oil, and still knocks. Oddly enough when on the center stand it was quiet. But as soon as I left it on the side stand for a minuet it started knocking again. Once it starts knocking it doesnt matter if you stand it upright, still knocks. Just to see I checked the balancer adjuster, but that didnt change anything. Sounds to me a crank bearing is gone. Thoughts?
I do have an apptointment with my dealer for them to diagnose, so we shall see.
Quite sad whatever it ends up being on this. Also upsetting since I have cb750 engine that are 40+ years old with no issues and a couple of them sat for 15-20 years in a barn. My bike stays in a climate controlled basement all its life when not on the road.
Thank you all, Ping
