I am in the midst of doing quite a lot of small jobs on my K1100LT.  I have removed the ABS, put in braided stainless hoses, rebuilt the front forks, installed gaiters, fitted relays to the headlamp which now has a high wattage bulb and ceramic holder, fitted daytime running lights and spot lights to come on with main beam, oil change, and many other little jobs. 

Today I thought I'd give the fan a spin, and discovered that it had seized.  Off came the radiator, and by some stroke of luck I had bought a bargain radiator and fan assembly on ebay some months ago, so after confirming that the new fan did indeed work, I swapped it over to my old, proven radiator. 

Of course, nothing goes smoothly; the two Allen screws holding the bottom of the fan to the rad had seized solid, so they had to be drilled out.  Luckily, I had a couple of countersunk stainless screws in the  spares box, so they went in.

It has all gone back together now, but I will be fitting an override switch for the fan, so that I can give it a short spin every time I use the bike.

Yesterday I discovered that there was a small spot of oil on the screw of the band that holds the gaiter to the swinging arm.  I am hoping that it will be a rear drive input seal that has let go, but at least it will mean that the bike now gets a spline lube.

I am hoping that I eventually will stop finding jobs to do, so that I can actually ride the bike. 

I know what you mean about the endless small jobs and the riding.
but as long as they are LITLLE jobs i feel it is part of the charm owning a 30yerar old bike

When you put the drive shaft back together make sure it is phased correctly.

Thanks for that Rick G.  I was aware of the phasing issue: I watched a Chris Harris clip about removing an R series paralever rear end.  At one point he says, 'We'll deal with the phasing later', but he then neglects to mention it any further. 

Now I will not have to research it any more.
