BMW R1100RS tear-down: screwed and unwashed

How I miss my old air-head. Or maybe they attracted a different kind of owner.I’m pulling the fairing off my new acquisition - a mechanically sound but cosmetically neglected R1100RS from 1997. That was the year it was last washed. If you have ever wondered what a “company bike” would look like, I’ll add some money-shots of filthy screws and rotten nuts. It was serviced regularly, although god-knows how Park Lane BMW managed to changed filters and fluids without disturbing the deepening patina of grime.

Anyhow, to the present and future.

I can’t free a couple of evil screws without damaging the fairing or tank: there’s one at the rear of the tank, where your knees sit, that just won’t budge. On the left side the previous owner must have snapped off the head in desperation, which is exactly what I resorted to on the right. There’s no way to get to the fuel lines etc. in order to remove the tank, but now it’s off, I’m still no wiser as to how this little bastard was supposed to do anything but annoy - it’s a phillips head, tapped into the fibre-glass tank, and the stud still spins tauntingly, as if there is a threaded backing tab.

So what’s the secret?

And don’t get me started on the daft little steel allen bolts in the front mudguard and fork covers: big mushroom head, tiny weeny allen hole, in the rainiest saltiest corner of the bike. You can’t even buzz them out without wrecking the plastic.

Now I’m into it, I can’t help but notice how rusty and crap-encrusted the shocks are. How difficult is it to change these? will I need special tools?

Advice, commiserations, encouragement, all gratefully received

As an ex air head you have my sympathy, but only so far.

If you owned an air head in the past, you should have expected this. It’s all self inflicted, 'cos you chose to buy it. (About the BMW line if you complain.)

More seriously, you do have my sympathy. BM’s have got consistently more cr*p, in terms of build quality, at an inverse rate to their changing/enlarging model range.

Quality was always a myth from about 1977/78. How they manage to keep that canard going for both their cars and bikes amazes me.

so whats the problem here? a 12 year old bike that has obviously been neglected, has suffered a predictable amount of corrosion, and is a challenge to dismantle? if it hasn’t been apart for years then that would suggest its been reliable for years? so wheres the problem? sorry but I fail to see where you are coming from on this, if it had been 2 or 3 years old then possibly, although poor maintainance is an owner problem rather than a manufacturer one. Drill out the screws and get replacements, copperslip the replacements, and the problem will go away…while you are at it, remove and copperslip all the other bolts that you can easily get to (not the wheel bolts tho) as to shock replacement you could do worse than go here and check out the search function, I would suspect that it will be similar to the replacement on the RT’s and that will be covered in detail, for spares try James Sherlock or moto bins or motorworks note, the various oilheads use different shocks so make sure you are getting the correct ones :slight_smile:
