I've seen lots of posts about different noise problems. I have the following problem with my 1999 cbr900rrx
It has 18k miles.
Engine is quiet and smooth in idle and in gear on the paddock stand through the rev range. No noises apart from slight noisy clutch basket when you release the clutch.
Under load when you get to just below 3k revs there is a loud ticking noise from the front of the engine on acceleration. This is only under load and disappears at about 5k revs unless you throttle back slightly and have constant revs. If you accelerate hard the noise is apparent straight away below 3k revs.
Downhill isn't as loud as the engine isn't under as much load.
I have had a full service, chain & sprockets, valves checked and just replaced manifold header gaskets. Noise is still there. I was wondering about CCT but its only under load and between 3-5 k revs.
It's very annoying but not getting worse as I've just done 800 mile trip round Belgium. It does not affect the performance and It's been dynojetted apparently when I bought it.
Can anyone assist with advice?
