Skip down to the last paragraph if you have no time to read about annoying cowboy mechanics.
Well, besides the oil, the garage also changed the clutch on my 40,000km, 2013 CB1100 (it didn't really need it, but I thought it will be ready for one soon anyway so why not? - the clutch plates are pretty standard parts). They also changed the head gasket, which was leaking tiny amounts of oil, but made it look a little dirty.
Note I'm in Vietnam so labour costs are really small. but parts can take a long time to arrive and be costly.
Anyway, now it clicks when I accelerate - it seems to be related to the speed of the vehicle, rather than the engine RPM. The volume isn't too bad, just noticeable at low revs before it gets drowned out by engine noise at higher revs (loud exhaust mandatory for Vietnam).
I took it back and they (say they) checked it over and they think the cam chain is a little loose/worn. I searched this site and found a few possibilities (e.g. http://cb1100forum.com/forum/showthread....=Clicking) - which suggests: 1. the cylinder head might not have been screwed back on very well, 2. fuel pump, 3. oil
The oil that was in it was Motul 10W50 synthetic - it's a hot country
He's taken out this (almost new) oil, and replaced it with 10W40
And they say they checked everything they had touched, including reseating the head again.
Does anyone want to guess that this is the most likely reason for the clicking noise, in combination with the cam chain being worn perhaps? How far do these suckers travel before things like this need to be changed? Who's winning the ODOMETER marathon? Surely we are seeing many on 100,000 miles by now - perhaps even 200,000? I'm on 40,000, and until now, have been very happy with reliability - marvellous comfy bike. My daughter also uses it to pick up boys as you can see in the picture.
