Sounds great.

I've not had a chance to do anything more with mine

Hi All,

My 250 has a Pro Circuit pipe.  No, I can't even push start it.  If
I kick start it, it will run for a few seconds and then is sounds
like it is just flooding out and dies.  I pull the plug and sure
enough, it is covered in premix.  I left my fuel petcock open (by
accident after trying to start the bike) and it just created a
puddle of fuel under the bike by morning.  Now, I fear the I have
fuel in the top end-hence the "gas fouling plugs".  I ride either in
poker runs like the Iron Man 100 mile race, or in Capital Forest in
WA state, or Manastash (great vistas in Eastern WA state).  BTW, I
also have a 1989 RMX 250 I bought on e-bay about 6 months ago that
looks like it has been in a plastic bubble.  No fluids in it!  Never
have started it!!!  A timepiece/ornament.  Gorgeous.  My 2 Yamahas
are "riders".  I can send more pics if you like.  Have some with my
13 year old daughter and her '03 RM85.  She went to Odessa, too.
She's pretty good.

So from what you know is your bike basically a bored
out 200cc? It's a 2-stoke correct?

Know much about similarities and differences between
the WR and YZ breeds?

What pipe did you put on?

Hmmm.. sounds similar to my 200.

Can you push start it?

Describe in more detail the carb problems and the
idling behavior and starting trouble? I know
describing this in words can be hard but do your best
please.

Whats a gas fouled plug? I've only ever seen a sooty
oil fouled one.

Does the petcock seem to leak if disconnected and shut
off?

Have you looked at the filter in the fuel pipe (hose)?
Look on the carb side, pull off the hose, and the
small filter (screen) will be in the brass fitting on
the carb OR stuck in the hose. Mine was filthy and
cleaning it fixed my cold starting problem.

Some of the other work I did may have made things
worse.:-(

> I am just avoiding any

Where do you ride?

I only have my WR or my street bike, so I need to get
the WR working. My Seca is not happy in the dirt. :-)

> It's a hoot when it is running
> well!

I agree!

> Will send pics when I get home.

Look forward to seeing them.

I need to shoot some more of mine. I have gleaned ones
off the net on my web page.

I'm excited to get mine working well again, a bit
frustrated now, but I am also enjoying the escape from
work and life stress wrenching on both my bikes.

Hello everyone,

Been having trouble posting my responses for some reason.  2 pics
posted okay, but not my text messages.  Anyway, my 94 WR250 (basically
a YZ250 with a wide-range 5 speed) won't stay running.  I left the
petcock on and I think it leaked and filled the top-end with fuel.
When I try and start it now it will run for a few seconds and then
just sounds like it is flooding out.  A plug check confirms this as it
is wet with fuel.  It's a shame as it runs like crazy when everything
is working.
I will be applying new factory (yamaha) graphics soon and will post
some more pics when that is done.  Plastics are still available if you
look hard enough!

Beau

Well, I got my bike started with a new plug.  I think there is more to
the mystery as I've changed plugs many time before with no luck.
Anyway, the bike has a monster mid-range when you crack the throttle
open, but under a light or no-load, it spits and sputters and seems to
barely run.  I don't know if it is leaning out, or whether it is
fouling out as it seems to like to do at startup.  May even be tired
reeds.  It has a boyeson sticker on the swingarm applied by the
previous owner.  Who knows what is actually in there.  Anyway, the
quest for a top running WR250 continues, and I'll keep you posted with
any lessons I learn as they will apply to your bikes, too.  Check the
pics in the photo section.  Can't wait to apply my OEM Yamaha graphics
on the new plastics I purchased.  Oh, I found one place that still has
the correct white tank (for $315!!).

Later,

Beau

Hey Everyone
No love from the Yammie dealer, cables and such are in but PV is B.O.d  till
June 19 then
should be shipping to dealer, so maybe I will see it early July. Meanwhile I'll 
have to keep
single tracking the DRZ (S) but that gets heavy 40 + miles into a single track
day.
Soon enough,
Later,
Wade

Prior assembly to my ownership and prior to the guy I
got it from.

It was the fact that the PV was 180 degrees out
(upside  down)
The power valve is a  2 piece item that is held
together with 1 bolt and 2 pins that changes port
timing when 12 volts is put to the servo motor.

It should take 1-1.5 hrs for full clean up and test
run.
Love the ease of wrenching on the 2 smokes.

That's possible. Trouble is there are a lot of
possibilities - meeting with my inexperience.

So I'm not sure what do next, or what the next,
cheapest, easiest fix... :-)

Is fixing a low end leak a MAJOR undertaking (bit
worried now)... Need to look at my manual this
evening.

I will take a look for that.

This is a "Leak Down Tester" as described in the

Mine is in nice shape,(fresh piston and rings STD
size) and runs well except won't rev all the way up,
so pull down was needed and I found a 180* out power
valve and a missing pin in the valve which trashed the

Hey.

So from what you know is your bike basically a bored

Know much about similarities and differences between
the WR and YZ breeds?

Hmmm.. sounds similar to my 200.

Can you push start it?

Describe in more detail the carb problems and the
idling behavior and starting trouble? I know
describing this in words can be hard but do your best
please.

Whats a gas fouled plug? I've only ever seen a sooty
oil fouled one.

Does the petcock seem to leak if disconnected and shut
off?

Have you looked at the filter in the fuel pipe (hose)?
Look on the carb side, pull off the hose, and the
small filter (screen) will be in the brass fitting on
the carb OR stuck in the hose. Mine was filthy and
cleaning it fixed my cold starting problem.

Some of the other work I did may have made things
worse.:-(

I only have my WR or my street bike, so I need to get

I agree!

Look forward to seeing them.

I need to shoot some more of mine. I have gleaned ones

I'm excited to get mine working well again, a bit
frustrated now, but I am also enjoying the escape from
work and life stress wrenching on both my bikes.

Hey, maybe you have a leak on the lower end.
I was digging around and found a leak tester someone
had built that was simple and cost $15.00.
I think it was on a KDX page somewhere, and was
roughly just a plate w/gasket that was built to cover
the ex. and a plug that went in the carb boot and a
gauge on the boot side, hand pump it up to 6  LBs and
let it sit for 6 minutes.
I'm going to make one soon, great piece of kit.
Later,
Wade

LONG POST:

I recently got a 1992 Yamaha WR200 2-stroke enduro
bike.

Before I got the bike it ran not bad and I had a blast
on the local MX track with it a few times, riding for
6-8 hours.

Big problem was it had a real bad problem cold
starting. You could kick it dozens of times until
exhaustion set in and it would not fire.

It took several trys to push start it until it would
fire up. Once warm it would kick over with reasonable
ease.

Trying to remedy this cold start problem I seem to
have made things worse. :-{

After Googling around I did the following both because
the bike was new to me and to try and fix the cold
starting:

- I set the throttle stop and pilot jet screw to specs
out of the WR Service Manual.
- Throttle free play looked ok and I never measured
it.
- I cleaned one fuel screen in the carb fuel line with
solvent and the cold stating improved dramatically.
With a few kicks it will fire up now. Still ran ok,
but not 100%.

Then I noticed dirt and crap in the tank:

- I drained the old premix out.
- I read on an Usenet post to water flush the fuel
tank to get non fuel soluble dirt out and not have a
ton of toxic chemicals like acid or acetone to deal
with. Sounded logical if carefully done.
- I flushed it good until all the crud was gone then
drained all the water out and then let the tank it sit
for hours with the tank off, the petcock and cap off
until all the water drained.
- I left it with the fuel cap off in the sun for a few
days until all traces of water evaporated.
- I cleaned the fuel screens on the petcock and the
petcock assembly with solvent. There was one screen in
the carb fuel feed (as noted above), and two in the
tank on the petcock feeds (one for ON, on for
RESERVE.)
- The screen on the reserve side of the petcock was
perforated so I removed it as I figured it would
collapse and plug up. They are not sold separately and
a new petcock with the screens is $40. I planned to
use an inline one and got one, but seems like there is
not enough distance to add it in between the carb and
petcock.
- I replaced the formed fuel pipe (hose) with a new
one as the old was cracked and hard.
- I added fresh Premium gas and Yamalube R in a 25:1
premix as per the Yamaha shop manual.

The bike started up great but wanted to stall and the
throttle is not as crisp as it was and it seems to
idle up slowly on its own now.

So I:

- I tried draining some fuel from the tank, and carb
bowel into a glass jar and see if there are any water
or contaminants present. It looked clean.
- I flushed the tank, fuel lines, petcock again only
with mental alcohol and drained it well
- The carb was very clean when I took it apart, but I
cleaned it again any way with carb cleaner and canned
air and put it all back together.
- Might be missing a washer only on the pilot air
screw, I also thought the washer might be stuck in the
hole. Nothing shakes loose with light tapping so a bit
unsure here.
- Float height LOOKS ok, but was not really sure how
to measure it properly.
- Installed a new gapped spark plug and switched to
50:1 premix with premium gas and Yamalube R
semi-synthetic oil. To see if rich fuel mixture or bad
plug was a problem.
- I tried to snug up all the boots and the reed block
bolts with my torque wrench

Bike starts after a few kicks, but again but still
runs so so, If I warm it up it does not really want to
idle on its own even when warm with the choke off.
Throttle response is sluggish when you crack the
throttle. Still revs up on it own after the throttle
is closed. If I play with the throttle stop and air
screw I can get it to idle but throttle response is
still crappy. And it will idle up and down on its own.

I also noticed the air box was cut open bigger under
the seat as well. Don't know if this is a factor.
Seems like it ran better before I flushed the fuel
system. Wonder if I released some particles into the
reed valve?

Got come PJ1 brake and contact cleaner and sprayed it
around the intake boot and it revs up and then down...
but it also revs up and down on its own without the
spray - so now I don't know if its the cleaner/air
leak sucking in the spray REALLY making it rev up or
not.

Now I'm frustrated an don't know what do next...


I also:

- I changed the transmission oil
- Changed the coolant with new distilled water and
50:50 antifreeze mixture.
- cleaned and re-oiled the foam air filter (used 10w30
as per the Shop manual as I didn't have foam filter
oil)
- I replaced my formed fuel line with a new one (old
one leaked and was cracked and hard)

Any help is appreciated.

Nice to have you here!

The group is still very small but we are hoping it
will grow.

I recently got a 92 WR200 as well and am very pleased
with the performance and condition the bike. I  am
however now having some carburetor like issues I'm
trying to sort out. I intend to detail the issues here
soon and see who has any ideas.

Later...

Hey a warm welcome to new member "beaulori" who has a
94 WR250 and joined us from the Suzuki PE group.

WELCOME WELCOME!

What can you tell us about your 94? Any pics of it
you'd care to post?

Ok the bike now has fresh a fresh mix of coolant and
distilled water on board.

I also installed a new copper washer on the coolant
drain plug as per the Service Manual.

The remaining fuel was drained and the gas tank was
flushed.

One of the fuel screens on the petcock is torn. Sadly
l dont see the screens listed on the Yamaha USA parts
site so will have to wait until Tuesday to see if
these are available - only the complete petcock
assembly is listed.

ln fresh solvent l cleaned.the air filter element and
re-oiled it with 10W30 since l had no filter oil and
this worked ok years ago on my Suzuki PE 175.111

l have some fresh premium gas and Yamalube R 2-stroke
oil mixed up 25:1 and ready to go.

Looks lilke the rear tire has some sidewall cracks and
l may need to replace it.

Side covers will need to be put back on and the bike
fired up and the coolant topped up.

Anyone know a good way to clean the seat and side
covers? l long ago used Formula 409 spray cleaner on
my plastics, but you cant buy it now.

l may take down and clean the carb.

Not sure I mentioned this, but the WR had a cold start problem when I
got it.

Cleaning the fuel screen immediately fixed it and ticked off the buddy
I bought it from who paid $300 to a local shop to have the problem not
fixed and the screen missed.

Off to do some more work....

Well tonight I fixed my tail light. No wiring problems thankfully -
just crud.

Both the bulb and fixture were really coated in rust. A battery brush
in the socket and around the bulb plus some WD-40 and a little elbow
grease cleaned it up nicely. It's working again.

I also replaced the nut that holds the bracket for the left air scoop
mount to the radiator. It was tight to get my fingers between the
radiator and the rock guard.  I used a little scotch tape to hold the
nut in a combination wrench while my screwdriver went to work.

Just a quick note to welcome the new nembers. Please take a minute to introduce
yourselves.

The WR arrived home last Sunday! As luck would have it, its been rainy and cold.
Tonight however I was able to start working on it, draining old fuel out,
cleaning the fuel screen, and changing the transmission oil. Looks lilke I may
have a small oil seal leak under the left half of the engine that will need more
investigation. For now though I am pleased to have the bike and be able to start
wrenching on it.

I created this group because I am buying a 1992 WR200 2-stroke and I
wanted a place for people to exchange information about this bike, as
I did not find another group or forum to do this.

I rode when I was 0 years old and have been off bikes for about 15
years. Recently I bought a street bike and even more recently a friend
took me out to blast around the local motocross track on the WR200 and
his 2005 WR450. I loved being back on dirt so much, I decided to buy
the WR as an inexpensive way back into the sport!
