I also decided that since the front end was apart, I'd try again on
the steering bearing replacement. I'd tried this once before, but couldn't
get the lower bearing race out of the steering tube. So I ordered the
high dollar Kawasaki steering bearing race remover tool, and tried again.
I can't get the damn thing out! The race sits in a flare in the tube,
and there's not enough of an edge to get any force on it. The tool catches
the edge and will take a pretty good hit with a drift, but ultimately
pops past the race. Any advice?

I really think a lot of the front end problems are due to loose steering
bearings. I believe if you can nudge the bars with the front wheel off
the ground and the front end flops over to lock, the bearings are too
loose. Also, if you take apart the front end to service the bearings,
they will have to be retightened after 50-100 miles. How do you check
your steering bearings? Take your hands off the bars at 50 mph going
downhill. Any problem with headshake suggests to me that the bearings
are too loose. I've been accused of running mine too tight, but I don't
have any headshake problems. I do have some pitting in the lower bearing
from neglect early in the bike's life, but that hasn't gotten any worse
in the last 50,000 miles, and I've got no notching or anything ike that,
so I don't think I'm running too tight.

RE: Low Speed Wobble (40 to 50 mph, hands off). If I have learned ONE
thing in my 8 years as the COG Tech Ed it is that the Concours is VERY
susceptible to loose steering head bearings, and the classic deceleration
wobble as the speed goes down through 48 mph is a symptom of loose bearings.
It ain't tires, OK?And, you can't detect loose bearings using the method
described in the shop manual. IT JUST WON'T WORK. Please use the method
described in Chalkdust. All Concours need their steering head bearings
TIGHTENED at 500 miles. This is rarely done by the dealer, as (a) they
don't know how to check for loose bearings as they read the shop manual
and (b) it is a lot of work and they just can't be bothered.
Let me repeat this: The Concours steering head bearings need tightening
at 500 miles. Probably 95% of all Connies out there have never had this
done. There have been documented cases where Concourts have reached
20,000 or 30,000 miles without having the bearings adjusted even once.
The Connie is big and heavy and the bearings are the same used on the
light and nimble Ninja 900. IT NEEDS TO BE TIGHTENED.
Now, you add this to the fact the OEM radials are so damn good at absorbing
irregularities, you get a lot of people who think that when they put
on new Metzlers or Avons the tires are bad. IT AIN'T THE TIRES! Adjust
your steering head bearings. It's easy.

Due to years of daily commuting, mostly in the rain, and a degree of
neglect, my steering bearings need replacing. The last time I had the
front end apart, I found that I could not get the bearing races out
of the steering tube with any tools I had or could rent. I broke down
and bought the official Kawasaki bearing race remover, which looks like
it will work fine. I'll try it the next time I change front tires. Meanwhile,
I'd be happy to loan it to any COG members who need it if you will reimburse
me for postage, and get it back to me in reasonable time.

RE: Wobble
Check the steering head bearings for proper tightness. Don't use the
method shown in the shop manual. Instead, place the bike on the C-Stand
with the handlebars centered. Stand to the left of the bike, and lightly
but firmly grasp the left handlebar end-weight with your left thumb
and forefinger. Push the rear of the seat down with your right hand
until the front wheel is off the ground and the rear wheel just makes
contact with the pavement. Release the right hand, allowing the front
wheel to drop to the pavement.
If the bearings are tight, you will feel only one "hit" at the front
wheel thumps on the pavement. If the bearings are loose, you will feel
a double "bounce" when the wheel hits. It's really neat, there's no
"feel" to this. Either it's OK and there is one hit, or not OK and there
is two hits.
Remember, most mechanics do not know this attribute of the Concours
and will, in all sincereity, tell you that the bearings are OK when
in fact they are not.
This is not a hard thing to do yourself, so why leave it to a mechanic?
The Concours' steering head bearing adjuster is ABOVE the top triple
clamp. All you need to do is loosen the lock nut (and either the lower
or upper triple clamp pinch bolts) and give a 1/4 turn or so to the
castlellated adjustment ring. POC.
