NC30 Tapping/Ticking noise - Exhaust Leak - Is it OK

[999Gomerz]

G'day,

I must admit that I have bought another VFR400, I rode one for the first time at a track day earlier this year and it was a bunch of fun. I bought one, rode it at a track day and now I have bought a second bike. I guess that means I am hooked.

Now, down to business.

The Second bike has a ticking noise at idle that appears to be coming from the right rear cylinder. I have checked and adjusted the valve clearances and that did not make it stop.
I pulled the plu on each rear cylinder whilst it was running and the this did not make the noise go away.
I can not see any black soot that would indicate an exhaust leak but I am sure it is cause of the sound and that it appears to be coming from the rear of the two vertical cylinders.

It is kinda loud and but only audible at idle, as soon as you rev the thing the full system makes it hard to hear anything else.

Is there a usual gasket that goes, ie the ones where the exhaust ports meet the headers or the ones where the rear headers meet the exhaust proper?

Or am I missing something.

Advice from those who know is much appreciated.

Cheers,

Adrian

The rear manifold to system joint does tick sometimes, try tightening it up or if that fails new gaskets, copper ones are best rather than those ally/fiber ones

I have this EXACT problem.

I'm glad you posted this because I was going to do valve clearances to try and cure it. I replaced my exhaust gaskets and tightened up as much as I dared (terrified of snapping a stud) but no avail. Is this normal? I've never met anyone else (in life) with an NC30 so can't compare.
