K100 service

Just doing a major service on the Beemer, after a very glorious 7000 km
and three weeks through NSW and Vic and down to the Island for the GP,
and am again bemused that a country with such a reputation for
engineering finesse managed to put together this bike.

Don't get me wrong. I love the bike. Ate up the km no hassles, served me
well under a variety of conditions but what a bitch to work on.

Doing anything of note means removing the bloody fairing.

Change air filter? Remove fairing.
Change coolant? Remove fairing - multiple times (well, I would if I did
it the way the manual suggests.
Change fuel filter? Don't remove fairing - just pull the innards out of
the fuel tank (actually, that's not really a chore - but I felt like a
whinge).

And why oh why did the engineer put the engine on THAT side, so that
when on the sidestand the head is lower than the crankshaft? Do they
have the sidestand on the right-hand side in Europe?

Anyway, engine oil, oil filter, fuel filter, air filter, plugs, coolant,
diff oil, gearbox oil and fork oil renewed today.

Brake fluid and lube shaft splines next month (first available day).

I had to put a new rear tyre on at Dubbo, on the way through. Chose
(cause there wasn't anything else) a Pirelli MT08. Quite liked the
handling, and after 6000 km the wear was quite good (about 40%), but the
longitudinal cracks were a worry.

Got the tyre replaced today, and the old one is heading to Brisbane to
get looked at by Pirelli. Hopefully there will be some refund due. I was
running it at 40 psi for most of the trip (the tyre is rated to 42) due
to the weight I was carrying and the sustained 'high' speeds.

What does a VB rating on a tyre mean? I've heard of a V rating, but
never seen a VB before.

Hopefully a fine day tomorrow. Heading up to the pub at Cooyar for
lunch.

It means the inspector was drinking VB at the time of the inspection.
Hence the quality of the tyre.

 

I think VR means the tyre has speed rating of V (210kph) and is a radial tyre
while VB has the same speed rating with bias belts.

but the

around the sidewall? My duc had cracks in the sidewall, was replaced free

Geez pete, must be your time of the month.

I have a 86 K100RS which I purchased in 87, sold in 98 and repurchased back
in 01 which now has 315.000k's on the dial.
Mate, you must be holding your tongue the wrong way or your smoking
material is better than mine because I have never had to pull my fairing off
to change the coolant or the airfilter.

Try putting your tongue on the RHS of you mouth might help.

Geoff and Jodie

 

Thank you, oh great one. That now makes perfect sense and explains the
state of the tyre.

[that HAD occurred to me]

Hmmm. Bias belts? Does that mean a nylon or what we used to called a
'rag' tyre?

I know the one that cracked (with the VB rating) was 130/80. The one I
have on now (recommended) is 130/90 and has just the V rating but is
stamped as 'nylon'.

No. Running along the treads in the centre of the tyre.

That is entirely possible. After a beautiful month off, it's been a
shitty week back.

I believe the RS has a smaller fairing (doesn't extend down the sides as
far) and therefore can understand how you can change the air filter
without removing panels.

But how do you do the coolant? The radiator cap is under the fuel tank.
To take the fuel tank off, I have to remove the inners off at least one
side panel, as the covers come OVER the outer bulge of the tank.

I do that often enough when I have tongue in cheek.

btw: has yours got that annoying knock at low revs when the engine is
cold? I've got 170,000 on the clock, and when I start it on a cold
morning it sounds like a diesel tractor.

They're all "rag" tyres Peter.
Ain't no such thing as a steel-belted for motorcycles.
[insert all of the examples where I'm wrong here;




]
Bias belt is "crossply" (as opposed to radial). They're stiffer and
generally higher profile but they run hotter than radials.
Clem

 

Pirelli Dragon & Dragon GTS are zero degree steel belted radials.

Be glad you don't have an oilhead. I was horrified at the last BMWMCQ
service day to see how much plastic has to be removed to do an service on a
R1100RT. At least on the K100 there is a reasonable gap between the airbox
lid and the top frame tube. K1100 has a larger airbox lid and is a real
bitch to remove (until you learn to lubricate the edges).

Pegasus

 

I don't have to remove anything to service my Oilhead or Bricks, that's
Ray's job.

Boxer

 

I know mine has and it has only 140,000 on the clock. I think the bike
has done more than this, the speedo isn't the most reliable.

BMW means Big Man's Wheels, not Bloody Moaning Whinger.

 

I had to put a new rear tyre on at Dubbo, on the way through. Chose

Pirelli Match comes in either crossply or bias belted, VB means its a V
rated tyre with bias belt construction. They suit K100s well.

Belly, left fairing, right fairing, tank shroud. That's hardly daunting is
it? About 17 fasteners per side, though, IIRC
