quiet when cold, rattles like mad when warm ??

Timing would want to be off by a good few teeth before it would bring compression down to 90psi and the  valves would be hitting pistons by then.
When I replaced my chain, the old one was one 1 1/2 length longer than the replacement.
I check the valve clearance for a friend last year and discoverd whoever replace the chain on his bike before he bought it had the timing on the exhaust cam out by one tooh and the bike appeared to be running fine.  I  lifted the cams and reset the timing to the correct position and put it all back together he took it for a spin and said he found absolutel no difference in the performance.
All the issues you have described point to the water pump, but you appear to have ruled that out. Never heard of cam chain or tensioner on a fazer rattling when hot and quite when cold, it has always been the oppisite. For out of balance to cause that kind of sound it would not even run.
Other possibilites are worn clutch drum, starter clutch as some else has mentioned cam shaft end float or a cracked shim or valve lifter, list is endless.
It is really now a process of elimination.

i will check the compression again when my 10mm adapter arrives, it was a quick check and if i'd done it at home i'd have taken my time with it.
might be checking the valve clearances this weekend so can check timing too, will also check the cam lobes etc at same time.












here is said water pump, nothing obvious to me when i had it out.
bearings ran smooth, if a little tight. seals looked in good nick.
i have now cleaned the pump as it was impossible to tell if anything was leaking from the drain hole due to it being caked in chain lube and muck.


i drained the water off and again had a slight rusty orange tinge and slight smell to it but this could be residue from previous coolant.
fresh in again with rad flush this time, will be putting anti freeze in at the weekend sometime.


i will certainly be keeping an eye on this and checking again in the future, haven't ruled it out yet.
