 I'm looking for a FZR1000 seat cowling (87/88) which was an optional
part from Yamaha, but has since been discontinued.  It covers the 
rear portion of the saddle (passenger) and racers often times use
them as a place to apply their numbers to.  Any leads will be greatly
appreciated.  -Andy

I'va friend who is putting a TZ250 back together (1983?).   Right now it's
short an engine.   He wants it as a street bike.   My (his) question is does
anyone know if he can title this bike?   I thought the title went with endgine
and if he puts a new  plant in, he'd title that way.   He says
the title goes with the frame VIN.   Comments?

You think that is amazing, I recently saw a program on tunnel boats.
These are little outboard powered racing boats. A tunnel boat can
corner in excess of 5 g's on the water. If I remember correctly
they have a top speed of somewhere around 140.

As for bikes cornering, a while back someone I worked with said that
he had heard that a lot of racing bikes can manager more cornering g's
than some race cars. However the cars can turn faster lap time because
the can transitions through the curves faster. I guess it takes less
time to swing a steering wheel back and forth than to toss a bike
back and forth.

I have wondered about the cornering g force numbers for bikes that
have been thrown around here. When I was racing the Pro-Stocker
it would pull something like 2 g's in first and that wasn't so
bad. As for cornering g's, my '88 Fiero GT is supposed to be able
to manager something like .85 g's on a skid pad, but I can go through
a corner considerably faster on my Ninja than when I'm sliding
the Fiero; that tells me that I can manage .85 g's or better on
the Ninja. (Kids, this is on Comp-K's, don't try this at home.)

Actually, F1 and Indy cars are about as aerodynamic as pickup trucks because
of all the downforce their fins produce. Having an engine that cranks out
around 1000 HP helps out tho. Amazing what they can do with 3 liters of
displacment...

   When I started, I bought an 1985 Ninja 600R.  It is not the fastest bike

   Avoid Katanas, as they are too heavy.

When compared to your Ninja?  <snicker>  Katanas are nice bikes.

   I would tend to disagree here.  Like I said, my first(only) bike is
   my '85 Ninja 600.

And I learned on an '86 Fazer.  Lots of engine, handles like a truck.
You learn how to be SMOOTH.  You also learn how to twist your right
hand (which is bad)...  The thing handles so badly that you scare
yourself before you get in any REAL trouble.  The best thing about it
is: NO PLASTIC.  When I dropped it off the sidestand (as all of us DO
once in a while) NOTHING was broken or scratched...  

I just did a similar test with my CBR600.  Fortunately, the plastic
was ALREADY scratched so I didn't feel too bad.  When I CRASHED the
CBR, the cost of replacing the plastic was $1500.  F2 plastic costs
even more...

My $.02?  Take the MSF course.  Buy something CHEAP with no plastic.
Ride it for a while (2-3000 miles).  Drop it, abuse it, beat on it,
then get rid of it.  By then, you should have tried a few other
people's bikes and can make a more informed decision about what you
want.

Of course, after 3000 miles on the Fazer, I still thought it handled
FINE.  <snicker>

-Patrick

P.S.   Oh.  Like Rich said, you WILL crash.  You should try to
       minimize the initial "I don't know anything" crash costs.

Only if it happens to improve the jetting, i.e. no.
I'd expect TZR250s to already be jetted lean for emissions, so
he'd have to rejet to compensate for the extra volume of
liquid (oil + gas instead of just gas).

The reliability issue can go either way. Some Yamaha oil pumps
(RZ500s) are known to 'stick' if the bike sits unused
for a long period of time with lots of oil in the tank.
If it sticks at minimum flow or max flow, you lunch
your engine.  I drain my RZ's oil tank if the bike sits.
for more then three weeks,
I'd really like some sort of pressure guage/idiot light
for the oil pump.  Anyone know of such a beast?.

If he switches to pre-mix, he has to rejet, which might
cause reliability problems if he doesn't get it right.  He
also might get the oil ratio wrong, or forget to add oil
to a tank of gas...

Actually, Russell may have had a wheel-changing advantage. There are
quick change setups that allow the rear sprocket and rear brake to 
remain attached to the swingarm with stub axles. The wheel has a 
triangluar shaped jobbie that fits onto these stubs. A full length
bolt (not really an axle) then fits where the conventional axle would. 
Just yank the bolt, yank the wheel, slap in new wheel, slide in bolt.
No futzing with getting things aligned or removing/replacing the chain.
The factory Kawasaki's didn't use the setup (it appears), but Muzzy's
crew very well may have. Of course, the bad gas can took away the 
whole advantage. Otherwise, the race might have been a runaway for
Russell. TNN should be faulted for not showing us this trick setup 
(assuming Muzzy used it). 

Despite the lousy coverage, at least we got to see SOMETHING. TNN 
should also be applauded for moving the coverage up to April from
October. Now we get to see the season opener before the season's
over! :-)

run on scenic Santa Cruz County backroads, and a raffle of some
spiffy motostuff.  A BBQ lunch will be available for a nominal fee.
Trophies and prizes will be awarded for the best poker-hand in the
following categories: British, German, Italian and open class motor-
cycles.  Registration is open between 7:30 and 11:00.  Cost is
$9 at the gate ($7 if pre-registered by 4/24/92).  BBQ lunch is

-> not.

 In the USA, the term "Water Buffalo" almost always refers to the
'70s-era Suzuki 750 triples.  Water cooled, two stroke, and double
coyote ugly.

 Of course, Suzuki has traditionally had a hammerlock on ugly.  The RE5
Wankel machines, the early Katanas, and others were pretty sick,
although some of the newer bikes are so ugly the Katanas don't look so
bad any more...

I find this difficult to believe.  A couple of good scratches through
paint into metal is about $400...but don't tell the cager that!

*Two* drivers hit you from the side?  That's pretty unusual, isn't it?
I would have thought it much more likely that they pull out in front
of you (not questioning your story, though).  Is there something you
wear that causes cagers to aim for you? 1/2 :-)

This is true, but sheep also cause substantial damage to cars.  Of

I'll see that batch of slimy sweat and raise ya the toe-jam from
my right foot, plus two days worth of bellybutton lint.

Oh, yeah.  And a pocket protector.

The problem with running a larger tube in a tire is that the tube may
have folds in it when inflated inside the tire and the creases in the
folds become weakened areas where cracks can form.  I've seen the
results in car tires before, the tubes failed along a fold by
cracking.
