So i have been turning the bike over each day for a few days now and from cold it is a little clicky.....
when i say clicky i percieve it to be the spark plugs - they sound rapid and constant initially and then after the engine warms up nicely they are much quiter and i eventually do not notice anything..for the most part....
it revvs fine, on the center stand, not road tested yet, and it revs strongly as i would expect to the limiter, no issue there...
so do spark plugs sound noisey initially or is that crap

i have not got lots of expeirence with these but i am 99% sure its not the chain - i will stick a video up of it - the chain should be spot on as i only just re-seated the head and its got lots of click on the tension adjuster.....also the engine has only got 18,000 miles on it....
it sounds electrical....if that makes sense.....its sounds sparky....not rattly or clicky like i would expect from a chain...but like i say little experience...
will rev it a little and see how the engine RPM changes the sound...
Arcing causes a clicking noise like you described. It'll rise and fall with the revs. Try running the bike in the dark you might see a little spark around the spark plug boots

Will get one from cold later tonight, but it seems to be just from cold....i think..
Again you are describing cam chain noise, going away when the oil has warmed up, which is a good thing.
If it was arcing then it shouldn't make any difference if the bike's warm or not.
As the Dude says, check it in the dark anyway, 'cos there is always the small possibilty it could be both!
More people are born because of alcohol than will ever die from it.
OK so have a video with it now - definitly.....can hear it clearly....uploading now....
IF it is cam chain noise, are we talking due to mis-adjustment, or tension adjuster not working, i know it was 100% spot on when i manually re-aligned with the head off.....

I can hear the cam chain.
As long at the noise goes away don't worry about it.
I've got sensitive hearing so it bugs the foc out of me, and it took about 6 months to click to next level last time as i mainly do short journeys without the chance of giving it too much welly.
When it clicked i thought there was something wrong, the sudden silence was deafening. :lol

ok cool - i shall run it for a little bit later and check it does disappear....
if it does not - what does it mean...is it the tension is not correct, when i re-aligned it i DID wind the engine through many cycles manually and so i know the "timing" should be ok....
OK so had it turned over a few more times and it is a rattle.......annoying the hell out of my now.....
Once i had got the head back on after snapping the cylinder head exhaust studs, it sounded smooth and no rattle...
SINCE then i have had to remove the tensioner and apply a NEW OEM gasket as there was a leak there as i did not use a new one....
And although i checked the timing manually i have actually not had it running since then - the past few days i turned it over and hence noticed this rattle..
So the fact i was messing with the tensioner does imply its cam chain tension related.....
I might get down to it the next few days and reset it - just a pain taking the tank and carbs etc off...
nah the chap who comes to revive me when i finally collapse after messing with this engine will have one... :lol
SO *** UPDATE *** i have got the carbs out and thought before i touch the tensionr i would pop the head cover off and check the timing...
Well after a few rotations i.e. 720++ its still bang on when TDC rolls over for Piston 1 - all the timing marks line up - does that imply its NOT the timing chain...would have tought if it was slack the timing would be shot...
I also checked the spark plugs, all seated fine and there is no sign of any loose chain between the sprockets....
I am not sure what to think as i am sure when i manually crank it there seems to be some slack
going back to have another look...on the plus side it was a rapid dismantle.....
OK so re-assembled it after checking timing and still sounds terrible.......no idea what to check next but will try your idea sinto, remove the tensioner gasket - worth a try at least i may know if thats causing it
