This is especially for MERFMAN, but there are some other KDX200
riders out there who might get off on this.

This an article a buddy of mine wrote about KDX200 silencers...
I haven't tried this, but I *can* say that the noise level is not 
impacted at all...Although my Answer S/A Pro is quieter than stock
ANY way, so...

Anyway, for my fellow KDX200 riders, check this out, and MAKE SURE 
you ditch the airbox lid in favor of a 89KX125 lid...There is 3
HP to be had there believe it or not!!

	The stock silencer can be taken apart into three sections:

	1) The front section (closest to the motor) has the baffles
	2) The middle section is where the packing is located
	3) The rear section is just a reducer

Take the silencer apart (probably needs to be repacked anyway) I use Answer
silencer packing, the kit costs about $11.00.  Make sure you push the center
section towards the back of the silencer when removing it, it's kind of
tricky.  Use a pipe or some other round object that fits into the silencer
and push out the center section using a hammer to hit whatever your using to
push the section.  Back to the baffle section.  When you remove this section
you will see the main pipe come through a plate into a chamber area, there
will be a second plate with two exit tubes leading to the middle of the silencer
Cut the second plate out by cutting the main tube after it passes through the
the first plate.  This eliminates the baffle.  Repack the center section and
bolt it all back together.  You will only use about 1/3 of the packing in
the kit.  Performance wise I was amazed with the difference!! It's the poor 
mans aftermarket silencer....

Hi,

	I was wondering what you all thought of the 1982 KDX 175.
The owner did a top-end job a year ago, has put new sprockets on it, etc.
since then.  Anybody know what this thing is worth ?

	It seems to have a monoshock and drum brakes standard, with 
the enduro lights.

	I'm thinking $500, but $350 would be even better, if I can get away
with it.

has them.  I don't understand it.  Are there some kind of import
restrictions or something ?  I guess there must be a huge demand,
otherwise.

	I just put some Metzler Uni-Cross knobbies on The Bitch, but
haven't done anyriding yet, as it's currently snowing.  Any comments from
nyone who has had experience with these ?

	They look like they would be a whole lot better than the crappy
IRC GP1's I had on before. I wasn't very satisfied with the traction I got
in the dirt with those things.  Ok on the street, though.

Subject: Any good ideas for service stands?
Organization: Hewlett-Packard, Santa Rosa, CA
Newsgroups: rec.motorcycles.dirt

Having just finished building a trailer, I'm still in the steel fabrication
mood and would now like to build a good service stand for my XR.  Anyone
have thoughts on a good design?

A simple platform is out of the question -- Scott Summers can lift an XR
off the ground but I sure can't!  Best I can do is lift either end maybe
6 inches off and muscle it around a little (from *plenty* of practice while
trail riding!).

The step-on lever type in local shops don't, I think, have enough lift
height to get both wheels sufficiently off the ground, and they don't look
very secure against tip-overs.

I'm thinking of using either a bottle jack (hydraulic) or large threaded rod
with an oversize wing-nut for lift, and angle iron that snugs up to the 
frame for tip-over security, but are there better methods?

P.S. I was a little hard on the bike yesterday - several new scratches and
a seat tear, so it's service time!  Yes, we went riding in the *middle* of
the week, and conditions were *perfect*  Cool (60 deg), damp (no dust), deep
blue sky (see forever from hill tops), and after riding 5 hours saw _no_
one else on the trails, and only 5 others on the fire roads!

Why not ditch the lid entirely?  I did on my 92 KDX 200 and
performance is excellent.  I also removed the regulator
which was mounted on the lid.  That was no problem, because I
also took the lights off and the regulator was no longer needed.
If you need to keep the regulatr, just zip tie it to the frame
or inside the airbox via some holes you drill near the top.
Don't forget to re-jet!

>The stock silencer can be taken apart into three sections:

What year KDX 200?  When I checked out the parts blowup on
my 92 KDX 200 silencer, I did not see any packing.  A friend
told me there was no packing in the newer silencers (89-93).
This is why I've never had mine apart for repacking, which
I would normally do on a 2-stoke several times a year.

>Although my Answer S/A Pro is quieter than stock ANY way,

My stock 92 KDX 200 silencer is quieter than **any** other silencer
of all the bikes ridden by everyone I know including those with
stock and after-market pipes/silencers.  But not including my
KDX 200 riding friends who have stock pipes/silencers.
The KDX pipe design contributes greatly to the reduced noise, but the
silencer is without peer.  I believe it's marked 80 or 82 db right
on the silencer (92 model).

I'm a big fan of quiet bikes.  It's friendlier and more
acceptable to non-riders, and my ears don't get so tired 8-)

	You might want to talk to the Northern Virginia Trail Riders (NVTR).
I went on a Dual-sport ride with them back in October, and I thought it was
great.  In March they're supposed to be doing another ride, this time all
off-road trails.  They seem to do a lot with the George Washington National
Forest in the Massanutten Mountains.  They supposedly do informal rides
at least every month, and the few trails I was on I enjoyed immensely,
even on my overweight XT.  Some great roads up there, too.

	The NVTR's address is :

	8313 Accotink Road
	Lorton, VA 22079

I think annual dues are $36 and they request that you be an AMA member.
Most of them seemed to be from the DC metro area, but there people from
other East-coast areas, too, and of course me, a Pittsburgher (though I
grew up in DC).

  Last Sunday I wanted to ride faster, but after the trip we made to the 
  swamp in the back I didn't have any forearms left.  When I finally mounted
  your KX250 I only had enough arms left to putt around.  Really depressing.
  I kind of thought about getting one of those hand-grip gadgets to work on

Hello there!
 
I'm new to dirt biking and I'm looking for some advice on bikes.
I have an '89 Suzuki TS125 which I use mostly for transportation to and from 
campus and recently, I thought I might give dirt biking a try.
 
Does anybody have any experiences on the trail or in the workshop, regarding
the TS series of bikes, that he or she might like to share?
 
I am also thinking of getting a KDX200 after seeing all my buddies
go for them. Here in Singapore we don't have much of a choice in scramblers
cos 2-stroke imports are banned and what we have now is what we'll be 
having for a long time to come! 
 
The KDX is the most popular bike here (the price tag will attest to that, 
too) but I was also wondering whether the bike is worth the +-US$4000.
 
My TS is in pretty good shape; I guess it'll go some distance on the trail,
does anybody ride a TS as well?
 
I'm a little above 6' and weigh about 180-185 lbs.
 
Thanks!

Organization: University of Illinois at Urbana

I have a question about a '73 Kawasaki H1D (500cc 2 stroke 3 cyl)
exhaust system.  I was going to post in rec.motorcycles, but there
seem to be more technical questions here.  This bike is of course
not a dirt bike, but if I get no responses here, I will post
elsewhere.

I recently acquired the Kawasaki for free.  It runs fine, but it
has nothing of the exhaust system.  I checked with all the dealers
in the area, and even cycle recycle in Indianapolis but could not
find a used exhaust system anywhere.  I did not think to ask the net.

Anyway, I ordered a new after-market system from Strader Engineering.
Walter (Strader?) told me it would take about 8 or 9 days to receive
the system after ordering it.  That was in early May.  After calling
many many times, I finally got the exhaust system in late August.  It
cost me $300 and it did not even fit and was 3 months late.  Has anyone
else out there ever dealt with this company or have any idea why my
exhaust system does not fit?

Some details:  I ordered the chromed system.  The plating job was
really bad, looked like they did not properly clean the metal before
plating it.  (Just a gripe)  The system feeds all three cylinders
into one resonator.  The original system had three separate pipes.
The Strader exhaust has the resonator and headers for the right two
cylinders all welded together.  The header for the third cylinder
is a short pipe bent in a U shape which feeds the exhaust into a
manifold which goes to the resonator.

So, the Strader exhaust consist of two pieces, one large one, and
one small connector pipe.  Well, I took the motorcycle and the
exhaust to a dealer after becoming frustrated and they also said
something was wrong.  The bike is unaltered.  The large part of
the Strader exhaust fit semi-OK.  But the connector pipe could not
possibly fit onto the exhaust system, this is where the problem lay.

I sent the system back to make sure it was made correctly.  It was.
Walter said that systems for '73 and after were very different than
'72 and before.  He seems to think that a '72 system will fit.  It
will cost me an additional $30 to get the '72 UNCHROMED system to
see if it will fit.  Besides, the bike IS a '73.  The cost of this
system is quickly adding up.  Does anyone have any advice?

A bike which is that old and especially one where there are not 
many bike shops for could cause many problems. I have know some
people to do similar things and then the bikes get left in the 
corner after a while due to a parts problem. You should consider
buying a newer bike. I am sure that you could pick up a bike from
the 80's for a similar price since the 80's are past. Even early
80's bike had the better suspension also. You don't want a 
bike which that old of technology suspension.

Many people ride bikes for a while and then let them sit. Keep your
eye out for a good deal. They are waiting for you to take advantage
of them. I picked up my 84 Sabre 2 years ago for $900 with 3K miles 
on it off someone who fell and decided to quit riding.
