Question about 1987 Honda CBR 1000 F
How do you re-set the alternator chain tensioner? I went to replace the alternator and I can't get the new one back in because the automatic tensioner has adjusted itself out all the way because of the slack on the chain from the alternator shaft being removed. @
40mm slack up and down middle of chain. not tight when sitting on bike. loosen axle ajust both sides evenly, retighten axle install new split pin

Lift the chain with one finger then turn the crankshaft several full turns by hand. Inspect the full length of the chain during rotation. Any obvious damage? Does the chain revolve smoothly around your finger? If all seems okay then the problem is probably not in the lower end. Some chains are continuous and do not have a master link. Some do have a master link. If you have a master link then separate the chain by removing the link then place both ends of the chain onto the cam sprocket and reconnect the link. If you have a continuous chain I would need to see first hand what is going on. In any event, be certain the timing marks on the flywheel and overhead cam are correctly lined up during installation.

yes it is safe for you to remove the tensioner unit whilst the engine is off however Iam inclined to think from what you describethat you are due for a new timing chain

You have a self adjusting cam chain tensioner. It is sold as an assembly. Take out the complete unit and replace it with a new one. The springs are not bad , the device that keeps the pressure on the tensioner is slipping causing a ticking sound.
