2 Plug R1100SA Top Speed...



Jack:

Let's see.  The bike is rated at 98HP at the crank and you think 90.1 at the
rear wheel isn't right?  Sounds right to me.   You could be losing a little
extra from the drive shaft.  All the other  bikes you mention have chains.

If you want to improve the power, you'll have to go to a Dynojet dealer, not
a BMW dealer.   It's doing what it's supposed to do, I think.

I just came back from Edelweiss French Alps Touring Center.   Spent a couple
days on a Twin Spark S rated at 98HP and a couple more on a new R1200GS
rated at 100HP.   They felt like they had about the same power to me.

The new GS is not K12 smooth, but it's much better than the 1150s above 4000
and all the way to 8000.   The new counterbalance gets rid of the hot spot
at about 5,000 where the older bikes really start vibrating.   Nice
improvement.    The chassis is a little nicer too.   The throttle response
is a little touchy at low speeds and takes some getting used to, but you can
be smooth with a little practice.

Don't know how long you've had your bike, but if it's not broken in yet (12K
to 20K), give it a little time.   It'll get better.  Oil consumption drops,
the engine smooths out and performance will improve.  The Japanese bikes
have more power, but not more riding pleasure.   I consider the S to be more
like a BMW 6 series or Mercedes SL, not a Porsche or Viper.  Sporty, but not
state of the art, powerwise.

The point of these bikes isn't that they are faster than the Jap bikes.
They are built better, have excellent power delivery and can be ridden very
high miles as a practical touring bike as well as being hauled around nicely
on a track day.

>Today, I had my bike dynoed: 76.2 rwhp at 100 mph and then it starts to
drop!

>Given the article in the latest Motorcycle Consumer News I am about 13
h.p. down from nominal. This was a freebie dyno run at an open house so
I only got a partial graph, i.e., hp v speed and no torque printout.
Most of the other bikes there put out what seemed to be the correct
h.p., e.g. an FZ 126rwhp, a Kawi R10 147rwhp, my son's GSXR600 (1999)
90.1 rwhp.

>At least I now have something to take to the dealer and perhaps get
them interested in bringing this bike up to spec.
