Hi All.
Looking for ideas from knowledgeable souls to help me get to bottom of this:
I've eliminated these sources of clacking noises:
- cam chain tensioners/guides.
- timing chain tensioner/guide (front of motor).
- TB butterfly spindle bearings - L & R.
- TB vacuum imbalance.
Symptoms:
- starting from cold: no noises; idles like a sewing machine.
- as engine warms up, clacking noise slowly appears, and gets progressively louder until engine is hot.
- when riding, noise is quite audible, but only on deceleration, below 3000 rpm.
- feel the clacking through the bars - fairly strongly.
- clutch operates smoothly. No change to noise whether clutch in or out
Oops: left out that the noise is coming from the clutch housing, immediately behind the engine.
Have stethoscoped poor old HerrFlick to death, and now fearing I might have to perform major explorative surgery.
Has been driving me even more batty than usual. Arrrgggh.
37,000 mi. (67,000 km).
Cheers and thanks.

Real torque curves don't have a first derivative. :-^)

Not much help I guess but I posted on here about engine noises at 65 k miles , did some investigation , replaced a camshaft and followers , engine is still noisy at 115k miles.... I looked at lots ,pushrods with pressed on ends (apparently the ends can become loose when they heat up) replaced with one piece , no different , did lots of reading on other forums , possible worn camshaft carrier , never got around to replacing...
I'm not sure about the vibes through the bars , but noise increasing with temperature would suggest something oil related.
Over the years people on here have reported that gearbox rebuilds with new bearings have resulted in a much smoother bike but any noises on these bikes usually disappear when the clutch lever is pulled.

Don't know if this helps.
Thanks Nigel.

Thanks Mitch.
I've decided to bite the 10mm socket and remove gearbox etc so I'll let you know.
Shouldn't take very long ......
Cheers
