nklr: jeff saline.. (any everyone else), bmw question

My buddy is selling an '01 BMW LT1200, 60k miles.
His transmission went out about 5k ago, the extended warranty paid for
half.
He's selling his bike, and I'm thinking about getting it for a nice
tourer.
I did some research and there seems to be lots of scuttlebut about
final drive/transmission/clutch failures in the BMW bikes.
Is this the case with this model? Any experience with this model
good/bad?
Thanks and have a great day!
Keith

Hi Keith
The M95 trans is basically crap. The next (M96) was better because
of better bearings. The M95 and the M96 are the same outside of
this. What you want to know is if that trans was up graded to sealed
bearings. I would hope that it was in the rebuild process.
The "other" problem with these units is in the builder. Was it
properly shimmed? If the trans was simply replaced with a genuine
BMW factory rebuilt unit, you can bet your last $ that the unit is
NOT properly shimmed. Getrag made these kwality units for BMW, they
always have. They also make trans units for Ferrari, Moto Guzzi...
Only the M95- 96 has this problem. The final drive is yet another
problem with that machine. The crown bearings fail.
My advice is DON'T buy it! For the money you can get a much newer
Kawasaki Concourse, and have a far better machine. If you are like
me, and love the boxer motor, that's one thing, get an older R. But
for the 4 cyl world the K is a great motor, but the Kawasaki is of
much higher quality. The only reason I own a BMW is for the engine.
I do plan to sell this heap of an R1100RS 1995 soon to buy an R100.
I just may even part it out and send the engine to Peru for my sand
buggy!
I spoke to a guy at out local bike night just tonight who was on a
new Concourse 1400. He is trying to sell his K1200 now. He is
another of us who will never buy another BMW product. The Kawi was
$7000.- LESS than the BMW, and just plain better in any way you
could look at it.

Just like the proverbial boat owner, the two happiest days of my time
owning an '02 R1150GS were 1) the day i bought it; and 2) the day I
sold it.
Maybe the K-bikes are substantively different, but I really think that
BMW engineers have these hilarious group meetings where they compete
to devise the most idiocyncrasies they can build into the machine.
there are about a million of them, but this was one of my favorites:
the fuel filter is INSIDE the gas tank. What's the significance of
that, you say? Well, the GS is advertised as an "adventure tourer." So
if you get a shot of bad gas in Timbuctu or Tierra del Fuego all you
have to do is 1) dump the gas and remove the tank; 2) take out a
sealed plate on the tank bottom; 3) fish out the fuel lines, fuel
gauge sender unit, etc., through a hole J-U-S-T big enough with
copious wriggling; 4) replace the offending filter (with one that will
take the 46psi fuel injection pressure -- every motorcycle shop in
Timbuctu will have one of these); replace the whole shebang into the
tank; and finally replace the access plate with a NEW O-ring (everyone
carries one of these, right?). And, of course, find some gas to
replace that which you just dumped into the sand.
To do this on my workbench took several hours and a full panoply of
tools. To do it roadside with the supplied tool kit would be a good
working definition of miraculous.
I'm sure when they were designing this there were more than a few
Teutonic guffaws going around.
Run...don't walk...from a BMW.

Idiocy. Right up there with late model Moto Guzzis having a spin-on
disposable cartridge oil filter. What's wrong with that, you say?
Nothing, other than the entire thing is inside a cast aluminum finned oil
pan that is maybe 10"x12"x2" and requires removal of a bunch of screws and
spillage of much oil before you can even get to the oil filter.
Probably designed by the BMW guys and sold to Guzzi.
One time I was tasked with installing some driving lights on a BMW K1200LS,
or whatever the one is that is the giant touring model with full fairings.
Just to get the one big side fairing off involved removing 36 fasteners.
I'm glad I am back to working as a UNIX sysadmin after that couple of years
as the sole tech in a small motorcycle shop.

This, unfortunately, is the case for all fuel injected vehicles,
regardless of how many wheels they have. The problem is called,
technically, "cavitation". Apparently the fuel pump must be inside the
gas tank (or immediately outside it) in order to properly feed high
pressure into the fuel line for the fuel injectors, otherwise it
cannot suck enough pressure because of cavitation. And of course the
fuel filter has to be on the fuel side of the fuel pump, makes no
sense to have it on the injector side of the fuel pump. Result: On all
modern vehicles (i.e. those with fuel injection), the fuel filter is
inside the gas tank and is a PITA to change.
We're talking about fundamental laws of physics, so there isn't
anything to be done about it. It's not that BMW sat down to decide
"oh, we want to make things hard for our customers", it's a
fundamental feature of all fuel-injected vehicles. For an adventure
bike there's something to be said for the stone-axe-simple approach of
the KLR, which avoids frou-frou like fuel injection and ABS in favor
of simple stuff that's fairly easy to field-strip and repair...

Well...not really
There is a mod for the BMW mess which puts that filter outside the
tank, used by the IBR guys and those heading outback. Take a lookat
most cars, they have the fuel filter mounted on the frame several
feet forward of the tank/ pump. There are of course exceptions, but
most vehicles have a frame rail mounted filter. Many newer- 2006+
vehicles have only in tank, but that's largely uhmerikin made stuff.
I just yesterday changed the filter on an '05 F150- frame filter.
Last week am '03 Hyundia- intank filter. Engineering outside
uhmerikah dictates that one installs an access port in the vehicle
body to access the in tank fuel pump & filter, instead of pulling the
tank and changing thigs on the dirt. My MotoGuzzi '00 Jackal has the
filter and pump mounted outside the tank- fuel infected too! That
bike does defy Fizzics though.

I installed a Martel Brothers Performance external fuel filter on my 95 R1100GS over 10 years ago...it has worked perfectly. MBP is no longer in business but other filters that work are available. Google Martel Brothers Performance you will most likely find what you need.The article below covers the task well.

Shane is correct. I did the external fuel filter mod on mine when I
had the tank off and the innards pulled out. There's absolutely no
reason why BMW could not have placed the filter in exactly the same --
and accessible -- place where I and legions of other GS owners have
put it.
The only possible practical explanation is that BMW engineers feared
that the filter could burst under the 46psi pressure and cause a
fireball if the filter were outside the tank. Uhhh...but when's the
last time you heard of a metal-bodied filter bursting?

Martel Brothers Performance you will most likely find what you
need.The article below covers the task well.
Which, as I point out, puts the filter *after* the fuel pump. Which
protects the injectors, but not the fuel pump, and since the BMW fuel
pump is not pressure-corrected (the reason why you need a return hose)
risks bursting the filter if it clogs. So you can do it. You can jump
off the Golden Gate Bridge, for that matter. It doesn't mean that it's
a wise thing to do though. You may be willing to live with the
(admittedly small) risk of a bursting filter. But it would be insanity
for BMW to do so.
The real solution is as someone else mentioned -- design it easy to
change the friggin' filter even if it's still in the tank. You ought
to be able to take out the tank, plug the vent ports, flip it on the
side opposite the pump, and just pull the whole assembly out of the
side of the tank with minimal loss of gasoline. I did that with my KLR
when I fixed the petcock the other day, no big deal, lost maybe a few
teaspoons of gas. Of course, if the reason you're doing this is bad
gas in the first place...
The moment BMW went with fuel injection they brought these
complications upon themselves. Unfortunately given Euro emissions laws
(which are much tighter for motorcycles than here in the US), they
didn't have much choice. BMW can be blasted for making it hard to
change fuel filters, but not for where they chose to put it. Every
auto with high-pressure fuel injection does that too, whether you're
talking the Jeep Wrangler TJ or the Saab 300 or whatever.
As for me, I'm stickin' with my stone-axe-simple KLR, so it doesn't
matter to me. I just don't like folks being blasted for doing the
sensible thing. Blast BMW for making it hard to change the filter, not
for where they put it, which is the same place that everybody else
doing high-pressure fuel injection puts it, for the same reasons.
