Similarly, my new R1100RT BM ran like crap so I blew $700 (IIRC) on a
major
service that didn't help. Wrench said it needed a minor adjustment (0=0
for
y'all BMrs) but it'd void my warranty. Happened to about 1 in 10 bike but
BMW NA's position was that I had the finest bike in the world and should
be
happy even if it didn't run. Ditto the chrome coming off my R1100C and
the
goofy wear that ruins $125+ front tyres every 4-5000 miles and ... and
.....

So you have the infamous BMW "surge" that BMW corporate denies even exists,
eh. So does my R1150RT. The local wrench did a fine job of minimizing it
without resorting to the Rob Lentini mod. (0-0, as you say) but it's still
there. To boot, BMW rearended my local dealership and ran them out of
business, so now we have no official BMW service here now. The wrench went
independent, and I use him for most things, but it's so damned typical of
BMW corporate to screw over its long-time customers. Hate the *******s, and
I've bought my last BMW bike.

Good luck with your bike, and do the Lentini mod, now that it's out of
warranty. The mod works perfectly, albeit the fuel economy drops a little
and the emissions get slightly dirtier. (Only Mr. Ganz will get his panties
in a wad over that.)

What is the Lentini mod? And what is 0-0 ?

Not to worry on your R100s. BM buys fuel injection systems pre-calibrated
from Italy for their R1100/1200 models. They have a simple pot (variable
resistor) on the throttle shaft that tells the computer how far open the
throttle is. About 1 in 10 of these are off a tad making the bike run
crappy. Bob Lentini's "mod" is simply to reposition of the pot with the
throttle closed so it sends the right 'closed' voltage to the computer like
it is supposed to do and does on most BMs. But the adjustment screws have
"tell tale" paint installed in Italy that perforce gets broken during this
fix so BMW calls it a "unauthorize modification". Replacing the $10/apiece
spark plugs with cheap US ones finishes the job.

Oh. Thanks for the clarification. I have Bing CVs. I like Bings,
real simple, that's what my Maicos had.

Shows you know nothing about carburetors for motorcycles.

Nothing beats a Mikuni carburetor.

The reason being is that Mikunis are totally adjustable
with respect to low speed, mid-range, and top speed
whereas crapola like Bings have no mid-range adjustment
possible.

Mikunis have air and fuel jets for low range
Bings only have a screw to adjust the air.

Mikunis have jet needles and needle jets for
mid range adjustment while Bings offer only
needle jets.

Both Bings and Mikunis have an assortment
of high speed jets.

Anybody who knows how to tune a motorcycle
for max performance given the altitude the
machine is used in knows Mikunis are the
preferred choice.

I hope this helps.

Beg pardon cappy, you may know more about sailing than me, but you
don't even come close when it comes to bikes.

Bings, and Amals for that matter, flow better at top end. That's where
you want it.

bottom end? mid range? Bah! WFO!

Smooth bore Mikunis flow better than your European crap
plus they have more adjustment possibility.

As for top end being the only important thing that is
bunk! If your motor stutters or gasps because of
poor low and mid-range jetting it takes a lot longer
to get to the rpms where the main jet circuitry comes
into play.

Mikuni rules!

I think not. I worked as a mechanic in a Suzuki shop for seven
years and then I worked as a Technical Advisor for U.S. Suzuki
Motor Corp for seven years. I taught carburetion in their
training center in Chicago and I taught electrical systems there
as well. I spent most of the time in the field helping mechanics
fix things they could not figure out. I'm good. Better than
you, I'm sure unless you can show similar qualifications.
