It comes and goes, along with a couple of other strange sounds.
Sometimes it sounds like the exhaust is leaking at the cylinder head - a mild "popping" noise.
And sometimes it sounds like something metal is loose - as though it were a loose camchain.
None of these noises occur at the same time, and sometimes they're not there at all.
It usually only happens when under load (not when coasting) - but not exclusively, it rarely happens when in neutral - whether the clutch is in or out.
I've got Honda CCT's with the stopper mod fitted, and I've checked that they're still intact using the screwdriver method.
It doesn't seem to affect performance at all, and doesn't seem to be affected by engine temperature.
I'm wondering if it could be a broken valve spring?
It's doing my head in - big time!
Follow-up:
The fault has now developed further - the noise has changed and has become much more consistent.
When it's ticking over, if I increase the revs ever so slightly the noise starts. Take it a bit further and it goes. It will do this for a short while only, then disappears. It will only start doing it again after it's been run a bit quicker.
Earlier this morning I read another thread about a very similar noise - and it's been suggested in that thread that it could be the front carb slide rattling. This seems to me to be very feasible in my case, as it does it whether the clutch is in or out, in gear or in neutral, engine cold or up to temp, and it only returns once the throttle's been opened up a fair way.
Also, it's been doing it for so long now if it was any of the moving parts inside the engine or gearbox it would surely have died by now?
I'll post this on the other thread and pursue it from there.
