If the rings are worn, you'd be getting blue smoke out of the exhaust, and a loss of power. More likely you may need a new head gasket -- is the leak coming from around where the engine block stops and the the cylinder heads start? Or you may need new oil seals around the camshafts. Clean the oil off carefully, take a short speed run, and see if you can pinpoint where the leak starts from

SOURCE: universal fuel pump versus genuine fuel pump for BMW K100RT

without changing out your fuelline I would not reccomend to go for a higher pressure and flow.
About the fuelpump....sometimes going for the cheap option is in the longrun more expensive.

SOURCE: What causes premature wear in the rings and bore of BMW K75s?

the K75 has very reliable engine .. its unusual for it to fail in this way .. the frozen rings would suggest overheating and thats possible if the radiator fan fails (that happens often before your 80,000) .. many of the pre 1990 k75s would smoke after storing for awhile .. that was a ring gap positioning problem .. that was corrected in newer models .. the smoke however would not have damaged the cylinders .. maybe in the extreme could foul a plug .. is it possible that someone put something in your gas tank ??.. or could it have been run without oil/water or perhaps the wrong type oil (like transmission fluid) ... that engine should have lasted longer than most cars .. nice smooth bike ..

SOURCE: 1997 BMW R1100R - front tyre scuffing rhs

The tyre could be worn like that simply because the previous owner liked right hand corners more than left or his common journey had more right hand bends.

But it could be a sign of something more serious.

It could be that the frame is bent at the steering head.(Or the swing arm is bent or swing arm bearings/bushes worn out)

A wheel alignment test should verify this.

It could also be a front suspension fault i.e. un-even adjustment of suspension settings (if it is adjustable) or incorrect fluid levels in the forks, or a bent fork tube
To check the steering head raise the front wheel up off the ground, grab the forks and pull back and forth. If you can feel movement then they are not adjusted properly.
Now turn the steering from side to side. The movement should be smooth and not notchy.
If any of these symptoms are apparent then the steering head bearings need adjusting/replacing.

To check the the swing arm bearings/bushes raise the rear wheel off the ground.
Grab the rear wheel and try to move it from side to side.
If there is movement the bearings/bushes are worn out.

To check the wheel alignment,place the bike on a level flat surface,loop a long piece of (thin) string around the back tyre(at about the 5 or six o'clock position viewed from the left).
so you have two pieces of equal length, long enough to reach past the front wheel.

Now pull the strings to the front of the bike.

Now position the front wheel straight ahead.

Now kneeling(or sitting on the floor at the front of the bike), place a string in each hand.

Now looking to the back wheel move the strings together until the string just touches the front edge of the rear tyre on each side.

Now holding that position, check the distance between the string and the edges of the front tyre to see they are equal.
If the gap is not even the bike has a twist,bend,missalignment somewhere.

If this seems a bit difficult you could try taking it to your local dealer where they can check it for you.

An experienced mechanic can perform these checks pretty quickly.

It usually takes me about half an hour maximum.

I hope that you find this information helpful

There is a possibility that the old motor was not burning properly and you have carbon build up on the O2 sensers. A poorly functioning O2 senser will not allow the Fuel/Air mixture to work as you give it gas under load. You could have multiple O2 sensers too.

Will a blocked pcv cause oil to blow out crank seal

A blocked PVC valve will not reduce the crankcase pressure and may induce oil leaks. If your lucky, a new valve will fix the problem, but I have never been lucky. Once oil starts coming out it seems to always come out until the seal is replaced. If it's coming from the top of the engine , it may just be a valve cover seal which is usually pretty easy to replace. All other engine seals are harder/more expensive and you have to decide whether the cost to fix is worth the pain of checking the oil, keeping it full, and the mess where you park. Also depends on whether the the oil leaks out abnormally fast - then it needs to be fixed. Usually the leak created by a blocked PVC wont be major - 1 quart @ 3,000 miles.

I have 97 custom fxsts S&S cases I tried to start it and all the oil ran from a rubber hose under the frame appears to be a vent

The engine "sumped". This means the oil drained from the oil tank into the engine crankcase.The hose is the crankcase vent. Start the bike with a pan under it to catch the oil coming from the vent hose. Run the bike to operating temp, then check the oil level. Top it off as needed.

Oil leaking from above engine. what could it be?

someone installed an aftermarket oil cooler on the bottom of the hood and it has sprung a leak. that is the only way i could see that oil would be coming from above the engine. of course you could have oil leaking from old valve cover gaskets on the top of the block. you could also have a crankcase pressure problem and oil is accumulating in the air cleaner via the breather tube on the top of the engine.

Leaking gasoline from gas tank after being driven the gas tank is not full and it stops when I relieve the pressure by opening gas cap.

there are allot of hioses and connections to these tanks that can be leaking, the leak in almost always on the top of the tank, u are going to have to get under the car and look for gasoline stains from the leak, if the gas stains go up and over the top of the tank then the tank must come out fro repair.

High oil consumpsion

U can have a cylinder leak-down test run for around $100 to see if rings are ok but I am sure it will just indicate you need to overhauled the engine, that much oil consumption is only caused by worn rings/cylinder walls or a blocked or partially blocked crankcase ventilation system (PCV).

Sound as though its anoisy bearing when car is started this noise occurs only for a few minutes then appears to go quiet only noticed it twice may be more noticable when out side of car

I used to hear this in about every car I have owned; the oil cushion isn't there for the first few seconds allowing a little more clearance than is present after the oil pressure is where it belongs.
As an experiment many years ago, I started using a molybdenum disulphide additive and have not ever heard it in another vehicle after adding the moly.

In some cars, it will actually improve fuel economy and power, - slightly.
For certain, it improves durability as even in small, high revving 4 bangers, it can extend the life of bearings and rings by (I'm not joking) by 50-60%.

I don't sell it, own no stock in any company marketing the stuff but have had a lifetime supply of the dry powder for 20+ years and have put some form of it in every crankcase of every car I have owned since 1968, adding a tablespoon with each oil change.
It has characteristics that no other additive can claim and the German military uses it as a matter of course.

One test I have read involved a high-mileage Ford V8 that had a commerically available moly additive added to the oil, driven for a under an hour to mix and circulate it through the engine.
The crankcase was then drained of all oil and the car was driven at speed around a track for over 100 miles before the engine finally seized.
