Hi people, I bought 1800sr last year and the guy I bought it from said it had a knocking sound because of old valves. It was a good price so I bought it without checking everything. Put it in the water late last year so I didn't replace the valves and drove it as is. It had the knock but drove okay. This year I had the valves replaced and a big maintenance but still, its knocking.
It knocks louder when it's cold and in neutral and low rpm. I don't know if it knocks when I'm cruising or I just can't hear it. I will post a youtube link to a video I filmed so you can hear it and maybe give me some advice, thanks in advance.
