Hi, i have a question for you.
In a rida CB550K0 with 14000 miles on it, picked it up in January. Seems to come straight from the factory, nice.
A few weeks ago after a drive, engine was idling, a cracking sound came from the engine. Hit it off, took off the top cover, and this is what i found. Cotter valve was split in two on cylinder # 4, the exhaust valve. I been asking around here in Norway, but no one have ever seen this before...?
So, the big question; have any of you seen this before? and, way did this happend?
Thank you
Lars M
