>> was held at Lake Whitney Cycle Ranch  Whitney, Texas.  I learned quite a bit

   Lake Whitney's a heck of a nice area isn't it?  I camped down there
   a couple of years ago, and canoed on the Bosque River before that.
   I brought my little XL125 on the camping trip, and I had a great
   time exploring the lakeshore and the dirt roads to the south.  It
   must have been spring '89 since the Texas wildflowers were in bloom
   (bluebonnets, Indian paintbrushes).  As I was *ripping* down those
   dirt roads (and across a strand of barbed wire with no probs
   thankfully!), I stumbled across the MX track.  I knew there was one,
   but not where...

   After carefully negotiating the caleche road to the track, I saw a
   few folks riding.  There was nobody at the gate, and it looked like a
   free-for-all, so I hit the track for a lap or two with my tiddler!
   That's all I could stand as those big jumps scared the piss out of me
   no matter what bike I was on.  Well after maybe a lap some dude told
   me I couldn't ride on the track with the lights etc. on my bike.
   Well sod off you, I tried to explore the rest of the area a bit but I
   wasn't wearing a lot of gear.

   How long did you say the cross-country course was?  I can believe the
   woes you had with that Texas rock and mud.  'Course we have had/will
   get a lot of rain here too... so I didn't bother to take the YZ with
   me for this weekend.  There should be a few chances to rock & roll
   before the snow comes.

   God I miss Texas sometimes.  The piney woods, Fredricksburg,
   Kerrville, New Braunfels, Austin...  I promise I will get there next
   spring.  I'll have my DR350 dialed by then, and maybe bring the YZ
   too.  See you on San Jacinto Day!

>Al, please elaborate on what porting has to do with ring life...Inquiring 
>minds want to know.

Piston rings operate on a bearing surface, (the cyclinder wall) for stability.
When a portion of that cylinder wall is gone, eg. (ports) the ring(s) can and
do start to flutter and twist very slightly.
The more radical the porting, (long transfer rates / large holes) the less 
support the ring(s) have and the less stable they are during their travels
up and down the bore.
Todays 2 strokes have gotten very exotic with their quest for the perfect 
powerband, and lots of it.
The dark side to this is that ring / piston life has dropped quite a bit
from 2 stroke designs  that were produced, lets say 4 or 5 years ago.
Life is full of trade offs, and we in the dirt world are no exception.
Now, if we could design ceramic cyliners and piston sets, then we wouldn't
need rings, then ........

You can dare me if you want, but I tried this weekend and only made it 3/4 of
the way up.  It's very difficult because of all the loose rocks.  I rode down
it several times with no problems if that acounts for anything.

Gary Bailey didn't make it up either.  He said jumped 1/3 of the way down once
and landed on a basketball sized boulder and crashed/tumbled/cartwheeled/rolled
the rest of the way down.  Ouch!

Yes, I used automotive H3 for my old XR with the quartz-halogen.  Much

We used to take riding trips up to the sand dunes in North Park.  The
standard plan was to arrive in the dark and take a spin on the dunes (to
unwind from the drive :-) before drinking lots of beer and falling down. 
On one trip I unloaded my bike, fired it up, and marveled at just how
bright the headlight was.  On the first rev, the bulb popped.  The voltage
regulator was shot.  I replaced it with a Malcolm Smith for a fraction of
the price of a stock regulator.  It worked just fine. 

Another thing you can do to help the life of your bulb is to install a
switch to turn the light off when not in use.  I installed one on my
Acerbis number plate/headlight.  It's a double throw switch to control 
hi/lo beam.  I made it part of the headlight assembly so that I can easily 
swap the entire assembly for a plain number plate when I know I won't be 
needing the light and I want to trim the weight.  The disadvantage to 
turning the headlight off is that you will probably blow more taillight 
bulbs.  Since my taillight is shot anyway, it doest't matter to me.

Yup, any visual encouragement would help.  I've actually compiled a list of

    All you have to do is get a voltage regulator.  The one a friend
    installed is made for Skidoo snowmobiles.  I picked mine up at a yard
    sale for a nickel.  Cool eh ??

    Bolt it right behind the head light assembly on the triple clamp.  
    Kawasaki has put a pre-drilled and tapped 6mm hole there.  
    
    The regulator I use is about 2" square and 3/4" thick, it fit in real 
    nicely.  The one I used has two wires that lead to a special connector.  
    Cut the connector off and feed the yellow wire into the hot yellow going 
    to the headlight switch (T connect).  The brown wire is grounded the 
    regulator frame, if you bolt the regulator to a metal surface you need 
    to do nothing with the brown wire except tape the cut end to cover up 
    the the exposed copper wire.  If you bolt the regulator to a non-groundable 
    surface (ie. plastic) you need to assure the brown wire is grounded.
 
    All the flucuation in brightness go away, and I haven't replaced a bulb
    since!

    Now, what I'd like to know is:

	Where can I get the proper bulbs without paying Kawasakis ridiculous
        charge ??  Jeez - I like to get kissed after I get f*cked* like that.

Well, I went and did it.
I heard some slapping going on in my cylinder last week on some downhills.
Sooooo, I went down to my local Honda dealer and popped for a new piston/ rings/
gaskets/ pin/ bearing.

The guy asked me if I wanted to pull my reed cage off, and I said no. (thankfully)
The damage came to $166.00 big ones!!!!
SHIIIIIIIIIIIIIIT!, I remember when my 250 yammer and my 370 suzi cost me less
than 60 bucks to do the same.
The parts don't look any different, except for the pretty red boxes, it must
be the boxes, yeah thats it.

Well, I lobe my CR-500 red rocket but, that new 250 YZ shure looks nice.
A top end job for that one ONLY costs $120 bucks.  What a deal.

After I had another look at my shop manual and supplement, I can see
the packing now.  It looks like a cylinder in the pictures, and I 
discounted it because it looked way too short to be packing.
Previously, packing that I had seen was 6-9 inches long.  The short
piece in the pictures fooled me.

Anyway, I ordered up the Kawasaki packing at about $12; expensive
but worth it to me in convenience and peace-of-ear. 8-)

When I disassembled my silencer, oil literally dripped out the end and
completely covered everything inside.  Needless to say, I cleaned it
all up before reassembling everything.

Maryland's Dept. of Natural Resources (DNR) issues a permit for off-road
only vehicles (i.e., if you have a duosport that's licensed, a permit is
not necessary).  It costs $15 annually and entitles you to use the ORV
"trails" at 6 state parks.  To get a permit you just show up with your
bike and some proof of ownership at the park office, and they issue you
a sticker.

The Maryland ORV routes at the two parks we've ridden
at were either fire roads or regular use dirt/gravel roads (where the
joy of riding is heightened by the fact that one may suddenly encounter
someone in a camper coming the other way around a hairpin turn...not
wonderful).  Of the six places to ride, five are out in the Appalachin
Mts. of western Maryland; one is one the eastern shore near the coast.
The eastern shore site (called Pocomoke) is a sandy half-swamp with about
12-15 miles of trails through the forest.  Absolutely flat.  The roads/
trails at Green Ridge State Park near Hancock run 7.5 miles 
along the ridge line of
a 3500 ft. "mountain", drop down 1500 feet into the valley parallel to
the ridge, go 7.5 miles the other way in a loop that is 16 miles overall.
There are campsites along the entire 16 mile loop.  Lots of verticals,
hairpin & S turns.  There is a powerline clearing that provides an
opportunity to climb 1500 feet over loose rocks in about 1/4 mile;
roughly a 45% grade.  Nice views of the Potomac river valley from
the top.

I don't understand the part about something melting down. During winter,
the dense air is going to make the mixture *richer*, which should make
the engine run cooler. Am I missing something here?

During high school and college, I rode my motorcycles year round (in
Connecticut and Massachusetts). Temps down to about -10F, and never any
problems. I never bothered to rejet, and never had any problems. My
experience was that the *rider* needed a lot of special preparations,
but that the *bike* did just fine in the winter.

I spent this last weekend attending Gary Bailey's two day motocross school.  It
was held at Lake Whitney Cycle Ranch  Whitney, Texas.  I learned quite a bit
and find that it's very hard to fix my bad habits in just two days.  The school
is geared more towards the serious racer in my opinion.  I would say my biggest
problem is that I do not keep my elbows up.  Bailey preaches smooth clutch
action and trying different track sections in the next gear. (4th instead of
3rd)  I crashed more than anyone else at the school.  Aren't you guys proud of
me. :-)  I now need a new front number plate, levers, gearbox gasket, and 
another rear fender.   I learned alot, but would have to think long and hard 
about spending $150 on another school.  I should be able to field questions
about the different things that he taught.
