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.
