Its a nice looking K BUT as mentioned every darn bit of seal and rubber will be in trouble. The list below is not exhaustive but does cover most of the items you will need to look at and budget for.
Water/oil pump and probably shaft corrosion.
Fuel pump/filter
Fuel lines
Cleaning injectors and replace injector seals.
Brake hoses
Brake system caliper seals
Brake system master cylinders seals and possibly piston corrosion.
Brake pads deteriorated.
Engine rear main crankshaft seal behind the flywheel
Gearbox seals.
Head bearings.
Fork seals.
Spline lubrications needed.
Bushes.
Brake switches gunged up.
Cable replacements.
Gear position indicator sticking.
Clutch actuating arm pivot bearing and seal.
Intake rubbers gone hard.
Possible gas tank internal corrosion.
Cleaning off all of the electrical connections.
The Corbin seat is lovely but will need a lot of patient care to soften it up again before use. It can be done and is worth doing.
I know I would love it but I would be tending to all of the above list before considering riding it any amount.
My own K has most of these jobs done either by me or previous owners and its getting the last ones on this list done next month. A lot of these you can do yourself and if you can do all of them yourself then I would give it very serious thought. The engines run forever and don't often need any work apart from the oil/water pump which is very accessible at the bottom front of the engine.
RickG mentioned the light restoration too, things like brake banjo connectors, engine casings and lots more showing signs of corrosion and needing cleaning up but really you should consider doing that yourself.
I have seen some for sale around €5,000 but these would not be needing that list of things to be done. A K with regular use and decent miles on it is usually a more reliable bet than one that's never used, unless the never used one is coming from someone who meticulously keeps it mint and minded.
