2004 CBR Very Loud Engine Knock
Hi, new to this forum.
Have a 2004 CBR 600 RR and I was riding a couple days ago and the engine started to make a very loud knocking noise, sounds like it's from the right hand side.
I took off the clutch cover and could see nothing wrong and so also took off the head cover and again nothing.
The engine starts fine, revs fine and goes through the gears fine but the knocking noise is unbearable. I replaced the CCT with a manual one and tensioned it correctly to no avail.
Any ideas? I do have video with the sound but struggling to attach it, will only let me attach photos
