Personally I would not use old hoses, you have no idea how old they are, they could be breaking up internally, and let's face it, replacements are relatively cheap, especially compared to wrecking your bike in the event of a sudden hose failure!
How much re-tightening torque are we talking about here?
you can replace the tensioner by just removing the lower crankcase but its still an engine out job. remind me what miles your bike has on it? If you have been reading about them you now know what goes wrong with the tensioner when chain gets slack, they don't work very well as the springs loose strength but you can use the small screwdriver down the blanked off hole to see if it is moving at all.If it was running before it will again before deciding what to do and you will not loose anything except a small amount of your time, it can always be done later just do not get disheartened.

You only undo the lock nut and adjuster bolt to allow free movement of the chain tensioner adjuster bar to allow the springs to push the chain tensioner adjuster bar to be pushed down further on to the horse shoe, which in turn, pushes the tensioner slipper on to the chain to take up the slack. It's an automatic tensioner. But for the process to work and remove any cam chain rattle from a slack chain, the chain must still be within service limit, the horse shoe pivot not seized and the spring not weak. As Bryan says, worry not now, sort it out at a later date if needed.
It maybe worth a look into Julie's engine rebuild thread to fully view the component parts and give yourself a broader picture in overview.If you want to check if tensioner is moving on a non running engine, loosen the set/pinch bolt, put something like a small screwdriver against the spring rod, and get someone to turn the crank anticlockwise (looking at ignition side) slowly. This'll put the camchain into tension on the "wrong" side and should push the rod towards your hand if the pivot etc are free. If it moves, then turn the crank clockwise and it should go back away from you again. At this point you can lock the pinch bolt again as all the camchain slack will be placed next to the tensioner and should be adjusted and held by the tensioner.
Yup it is, 22k if look after and adjusted regularly should be OK, ignored, abused and not adjusted often wrecked------who knows!
Only answer to that is stay in and put more logs on the fire!!

We may be talking semantics here. Since there is a locking nut, I figured that the adjuster wasn't relying on torque alone to hold it in place, but the manual does say to re-tighten it, and to my mind that means some kind of torque - even if the intent is only to tighten it just until resistance is felt. The answer to "how tight should it be?" is a torque value, isn't it? The manual reveals nothing on this score...
