I know what you mean about flex on the standard forks.  That's one of the
main reasons I would like to sell the 89 KX250.  They just don't have
enough stiffness.  The action of the forks is great, but they leave a lot
to be desired when slamming bumps.  I don't know about the 88, but I'd 
think that the 89 is about the same fork.

When I'm coming out of a corner and have to start slamming big 
acceleration bumps while still turning, it seems like the front end is
all over the place.  I get through it by letting it see where it wants
to go, then trying to pick the best line through it's desired area.

Slamming big choppy whoops is about the same story.  If I hit all of the
whoops perpendicular, it's ok, but I can get real out of shape if they hit
at much of an angle.  

I think that it is all from the fork flex.  I can hop on Mike's CR (USD forks)
and carve whatever line through the same corner or whoop straight and the
front end tracks right where I point it.  I'm pretty sure that the difference
is the USD forks since his bike isn't even set up for me.  I've also noticed
this difference in other USD fork bikes that I have ridden.  I also noticed
that they all did seem to have a stiffer action to them.  I want USD forks
that will soak up the bumps as plush as my stock 89's.  Yes, I want to have
my cake and eat it too. :)

I'm trying to go fast and slam things like Mike, but those conventional forks
just don't cut it the way they are.  I think that I'd rather take the knocks
through the bars and bike instead of the forks flexing and sending me the
direction it likes.  Maybe we just have different riding styles.  I don't 
like the flex.

If you really want Bultaco parts, try calling Martin Horn at Aero-P.A.

midwest back in the 70's and he is always ready to talk vintage

I just bought a stand for my bike.  It very simple to use and if you weld,  
you can easily make one for yourself.  It is basically a rectangle built from
square steel tubing (1").  This part lays on the ground and it has a long
handle (welded on to it made of the same steel) that sticks strait up.

You just slide it under your bike and push the handle to the ground and the 
the bike gets one end lifted.  You must move it around to lift either the front
or the back.  Mine works just fine and I bought it for $35.

Don't limit yourself to YZ125 forks.  They will definitely be under sprung for
your XT.  Go for some off a 500cc bike if they will fit your triple clamps.
You also have to factor in that the front axel size needs to match from the XT
to whatever forks you buy.  You can adjust the handling of your bike with the
newer fork buy sliding them up/down in your triple clamps.

Yes, you will to have to rejet, or something will melt down. Buy a
number of jets (main and pilot) in the 10 to 20 percent larger than 
stock range. It's better to be too rich than too lean, so start with the
largest jets and the needle all the way up (clip at bottom) and then
start reducing their size until its jetted right.

Again, play with jetting. I think bikes are generally jetted rich from
the factory , so dropping the jet size will usually give better power
and throttle response. You have to be careful when reducing jet sizes not
to go too far and melt something down; learn to read your plug. If you've ever
run out of gas , you probably noticed the boost in power just before it
died. Not a good thing to do to your motor, but it shows how well it 
responds to a leaner mixture.

If you want to learn more about carburators, order the "mikuni super
tuning" manual from your dealer. It's not great, but its the best thing I've 
seen. I think its about $10. If your dealer can't get it, email me and I'll
see if the manual has any ordering information.

Running a synthetic oil that can be mixed at a much lower ratio should also
give slightly more power, since more of the mixture will be fuel. 80:1
and even 100:1 is not uncommon with motul and optimal. I use the motul
at 64:1.

Good luck,

>I want to put dual carbutators on my 1992 XR250R.

Why?  Having owned the dual-carbed 83 XR350R and the 84 XR200R and
also having helped many friends adjust their dual-carbed models,
I can see no reason why you would want to subject yourself to
the same sort of punishment 8-(...  Honda themselves decided that
the dual-carb setup was not the hot setup.  (Maybe because people
like me complained about how hard they were to set up.)
On the other hand, my friends with dual-carb TT600s had no
problems with their jetting.  The Yamaha version used a single
float bowl, with only a main jet in the secondary abbreviated
carb body.
I'll admit that the idea of dual carbs seems like a good one:
one small-throat carb for low and medium speed and a second
carb kicking in at larger throttle openings for high speed
should give you excellent performance in all areas.  But in
reality, the secondary has to kick in too soon and the mid
range response suffers.  If you jet for mid-range, then
somewhere else seems to suffer.  I think the limits on
carb linkage and the use of two carbs of the same
design (size, etc) didn't allow Honda to get the effect they
wanted.  In my opinion, the Yamaha design worked better
because of the difference between the primary and secondary
carbs.
When we get fuel injection with computer control, then all
of this will be a bad dream 8-)

Lastly, I think you will find that the cylinder heads are not
interchangeable between the 84/85 short stroke/large bore
engines and the 86-and-up long stroke engines.  Check the valve
cover and/or head gaskets to see if the shapes are even close.

I went through a nightmare of my own when trying to convert
my 84 XR200 to a 250.  Everyone, including the parts guys, said
that the engines were identical, except for bore size.  Well
they differ in two other areas: deck height and cam chain length.
Seems that the 250 barrel was a few millimeters taller than the 200,
so the cam chain was longer also.  When I tried to put the taller
250 cylinder in, the 200 cam chain wouldn't fit.  I ended up
putting a larger liner in the 200 cylinder, and putting the 250
piston in.  That was even problematical.  The pockets in the top of
the 250 piston were not deep enough, and I had to mill them out.
When all was said and done, the '250' didn't perform that much
better than the stock 200, probably because of some other
subtle difference that I missed (cam, CDI, exhaust pipe length?).
I hate to think of what kind of fit problems you'll go through.

Be sure and keep us posted on your progress, though.

  Its all great fun.  But if something is holding you back then maybe it

  the new engine.  Yeah, I think I'm due for a core sample.  Anyone care

No, a simple platfrom can work.  The one I made is high enough to hold both

I put a 2" board under the sidestand, then from the right side of the
bike grab the front brake and lean the bike over on the front wheel and
sidestand.  Way over.  Shove the stand under the bike.  Tilt the bike
back upright and wiggle onto the center of the stand.  Easy.  

I used 1/8" thick diamond plate 14" sqaure for the top.  1" gas pipe for 
the legs with 1/2" square solid bracing near the bottom of the legs.
2" by 1/8" strip around the top of the legs welded also to the diamond
plate.  Massive overkill, but it works great.

Did someone say Bultaco ??

Man there is a guy here in town who rides the vintage class occasionally
who has a PURRRRFFect 71 Pursang.  The thing is a MONSTER and is absolutely
box stock except for a slip-on (and it's STILL LOUD AS HELL!).

I spoke with this guy and he's had it since it was new.  I walked away
with a puffy that wouldn't go away for a WEEK!

Frankly though, I'd LOVE to have my old Ossa 250 Pioneer back.

Someone emailed me some time ago asking for details about the mods made to
CR500RR. I can't find your message, so if you're still interested, drop me
a note.

If you're interested in building something similar, definately give it a
go. Most fun I've had in a lonnngggg time.

Cheers
