98 1100GS bought new, serviced exclusively by myself except for the 1,000 Klm service.

Battery went at about 6-8 weeks, replaced under warranty.

This year the ignition wiring loom cracked and died, something I never would have suspected, replaced it and fixed it so it cannot happen again.

Just this last weekend whilst servicing, I was replacing the fuel filter and I checked out the filler cap water drain pipe thingy. The part of the drainage system that passes from an internal (to the tank) hose to a metal pipe that passes to an external hose was starting to rust and scale up, which was preventing water draining from the fuel filler cap recess. I cleaned it out thoroughly and then re-assembled and now it works perfectly.

The bike is never ridden to work or any kind of commuting, it only does trips and sunday/weekend rides. The bike has been into some interesting situations dirt wise and water crossing wise whilst solo, but is mainly used for two up touring and is heavily Tourateched.

Now has 73,000 Klm's on it, and, apart from normal wear and tear hasn't had a fault worth mentioning, or one that I can readily remember.

Previous 1982 R100CS had 305,000 Klm's on it and I never had the cylinder heads off. replaced the clutch, G/box and rear shockers at 275,000 Klm's, apart from that, nothing much else.

Bike before that was a 1980 R80 G/S it did 85,000 Klm's and went through two clutches and two rear suspension units due to extreme thrashing by me ( I was younger). It got completely submerged during some river crossings and hopelessy bogged in mud, sand, and scoria (Volcanic stones) It did have an extremely hard life.


Bike before that was a 1977 R100/7 which did 350,000 Klm's It also got bogged badly in various situations, but we floated it across deep rivers. Rebuilt the G/box, as in bearings at 300,000 Klm's and replaced the clutch at the same time, kept the original clutch as a spare as it wasn't worn too much, that bike went through two rear main seals and about 10 sets of rear wheel bearings. The wheel bearings died due to lots of water crossings followed by sand, weak part of the bike actually.

Bike before that was a 1975 R90s which did 115,000 Klm's. This bike was raced in road racing on tracks and went touring everywhere. Broke the rear subframe in 17 places on one trip to central Australia, cartwheeled it on another trip and stuffed the re-welded sub-frame which eventually led to replacement of said sub-frame. This was my first new BMW and since then I've never really had a problem. I onsold it to a mate who still owns it, he restored it to as new condition after 500,000 Klm's

I had various secondhand BMW bikes before those mentioned above and apart from a real stinker of an R68 they have all been reasonable.

Basically the machines are soundly manufactured and if you look after them normally and take the good with the bad then they are pretty good bikes!

That's 'cause he rides like a poof, and he watches Eastenders... try phoning him when it's on, he loves it when you do!

No problems as such. Some corrosion, but it is used all year round and it's previous owner kept it outside. No surging, ABS works as it should.

I'm with Jamie, any probs I've had can really be put down to wear and tear. :beerjug:

What about those leaky seals Den????
 
02 Adventure 22000 miles

1. New rear shock
2. Oil pressure switch
3. Fork top caps
4. Screen
5. Paralever bearings
6. Output shaft seal
7. RID
8. Fork brace
9. Brake pipe
10. Rear light
11. Oil leak
12. Petrol leak

All fixed/replaced under warranty and i still think it's the best bike out there!

One of the good ones obviously :yelrotflm
 
98 11GS, bought with 25k, now coming up to 70k (miles, not km...)

48k - new rear shock

57k - crown wheel bearing

66k - exhaust support strap

Nothing else that can't be attributed to wear and tear or me falling off:rolleyes:
 
2001 1150 GS 57k

In no particular order

1) Brake line (recall)
2) Clutch (50 -50 with BMW)
3) Corrosion everywhere (dealer painted the fork legs, lasted at least a month)
4) ABS Front sensor (failed whilst in the garage having the clutch replaced)
5) Rear Shock
6) Paralever bearings (dealer says these are effectively a consumable)
7) Poly V belt failure (4000 miles after the 48k service at which it is supposed to be changed but wasnt)
8) 2 oil leaks (pinched gaskets after services)
 
2001 1150GS, 14,500M, dealer serviced - no problems other than oil consumption but that seems to be dropping very slowly now.

Funny you should mention that Rich, just done another 3600 miles around Europe without a hitch. Overall I've done over 15000 miles since you first noticed the ominous stain around the clutch housing without any sign of clutch trouble. Beaky is on 56,000 at present, no slip or other problems....could it be that the dealers just like earning a few bob needlessly changing clutches. Or of course using it as a bargining point to make a lower offer on a part ex when in reality it is nothing at all to worry about.

Makes you think doesn't it?:(
 
Interesting, Dennis,
Cooper Reading just told me my clutch seals needed replacing, that there was too much free-play in a thingy at the back, and that my rear brake disc (yes disc) was too thin and needed replacing. Hardly ever use the damn thing.
I know (and so do they obviously) that I'm a technical moron, but surely they're taking the piss ?
 
surely they're taking the piss ?

Gasman, could well be. IMHO a better and cheaper option is to join BMW assist , just in case. At £95 per year (including unlimited European wide cover) it's a steal.

With regard to the brake disc, how many miles/sets of rear pads have you gone through? Does the disc feel rough or corrugated ?, which might indicated that there has been metal to metal contact. I actually use the rear brake quite a lot and after 56K miles 3 years and 4 or 5 sets of pads it is still within spec.

It is easy to get someone to check it out for you with a micrometer or vernier guage. If you fancy a run up to Wales I'd be happy to oblige, or alternatively I'm off to the Bike Show on Sunday if you fancy a run up to Brum.:beerjug:
 
I know what you mean about the clutch thing Den, my last 1150 had the same symptoms. Bumped into the guy who bought it from Bath Road about 8 months after i traded in and he'd been to the South of France without any problems. Basically, keep running it until you get clutch slip and get it all done then.
 
Thanks for the advice, Dennis. I'm sure there's been no metal to metal, and I'm only on 2nd set of pads after 40k miles ! I'm going to have a closer look at it, though.
Unfortunately don't think I can make it to the NEC on Sunday.
Great GS roads and scenery round your way, I recall. Used to live in Swansea. :thumb
 
The early (up to 95) gearboxes were fitted with taper roller bearings; these can have problems when the case hardening gives up the ghost. BMW do an upgrade kit that replaces the tapers with conventional bearings, it cost me £280 for the complete upgrade (including new clutch plate) and that included replacing every bearing and seal in the box. The early gearboxes rattle at tick-over to try and cure this BM put ‘O’ rings between the gears (96-97 gearboxes) this resulted in too fast a rundown on the gearbox shafts making the boxes ‘Clunk’ more than the earlier ones. The later gearboxes (97-99) are well sorted apparently.

The early bikes had head gasket problems, the gasket was redesigned a couple of times and the latest design is a bizarre multilayer thing that seems to work fine.

My 95 1100 is coming up for 40K here’s a rundown of what has been done:

4.7k – Both head gaskets blew
20k – Rear drive shaft pivot bearings replaced (grooves in bearing surfaces)
28k – Battery replaced because ABS not engaging (Hawker fitted)
29k – Gearbox upgraded to later spec due to excessive noise (clutch only half worn but friction plate replaced anyway)
29k – Head gasket replaced with latest design (slight weep on one cylinder).
29k – Rear drive shaft pivot bearings were found to be worn (again!)
32k – Speedo cable replaced.

That’s a total cost of around £500 for non planned maintenance, which in 40K is pretty good. I service the bike myself so a major service costs around the £50 mark and a minor around £30; which gives a rough maintenance cost of £19 for every 1000 miles.
