Hunt down Mike Sturdevant.  His has older YZ125 forks on his XT500.  The 
tubes from a larger motocross bike will not fit into the head clamps on 
the 500.  You can stiffen up the 125 springs by removing a coil or two 
and adding spacers.  

I don't think that you'll have any problem with steering geometry.  It
certainly doesn't slow down Mike.  If you tried to use forks from a newer
YZ with 11-12 inches of travel you might have a problem.  

If you really want forks off of a larger MX bike, you can try swapping the
triple clamps.  On my XR, the CR250 clamps were a direct swap.  I put in the
optional stiff springs for a CR500.  The entire front wheel assembly and
brake are from a CR.  Moose did a pretty good job of revalving the whole
thing.

I think the first year Yamaha made the TT500 (1977, a high school friend
traded in his Maico 400 for one) they had a stainless steel type gas tank
with orange stripe down the middle and orange fenders and  number plates.

I like riding my bike and plan to do it all winter long, snow
ice, sleet, whatever.  I recently saw a posting about changing
the jet for cold riding.  (Sometimes it gets -20F here)

Do I need to do this for a Yamaha DT250 '79?  Also, does this
involve going to the dealer and asking for a cold kit or something?

Another question.  HOW DO I GET MORE POWER ON THIS BIKE?  Do I
just need a bigger bike, or can I do something to the carb?
Any low budget ideas?

Also, I never hear mention of DT's on this net.  Are they just bad
dirt bikes or are they not even considered dirt bikes?  I only
got it because it was so cheap, but in very good condition.

    Nothing different really.  Are the tires, chain, paint, engine OK

    Hmm is right.  Try some smaller shops, and keep looking on those
    back roads out in the country for a telltale trail that might lead
    to a riding area.  Old quarries, pits, farms, horse trails...

Hi,

	I'm thinking about putting some YZ125 forks on my XT to get
more travel.  The only thing that bothers me is that the forks from
and '80 YZ are way longer than the XT's.  I am trying to figure out
if that will screw up the steering geometry in a big way (not it's real
great to begin with).

	I was wondering if anyone had any opinions.

Cool.  I love it when local groups make the youngsters feel extra
special.  They are the future of this sport! (and everything else for 
that matter.)

I manage the outdoor portions of a local supercross here every year.  
Every year the event that gets the largest spectator participation 
is the peewee's.  We shorten the track and have them ride around most
of the nasty peaked type jumps.  The little guys/gals have the most
determined looks in their eyes of anyone who rides.  I personally love
this part.  After the event we tropy ALL the participants and usually
interview 4-5 of them over the PA if time permits.

  Hey George, could you elaborate on this?  I just burned the premix I had
sitting in my garage for a few months last weekend and, as far as I can tell,
nothing bad happened.  I even went through some sandy areas that taxed the
motor a bit.

  What should I look for?  Gumminess, fouling, seizing?  How does it break

I don't get it. Suck what to see what?

What you say makes sense, but the icing that I have had trouble with
was in the bowl, on the float needle. This of course resulted in flooding
problems. I'd be careful about keeping my tank full to minimize condensation
but still have the problem. Adding gas line anti-freeze to every tank, to
stop the moisture build up, cured the problems for me. I recommended the 
av gas because I know pro ice racers who use it, and I think they use it for
this reason as well as the higher octane. I've never used it myself, and
haven't decided if i'll try this winter or not.

If the icing is on the slide or the venturi, then you're right, fuel
change won't help.

Since you're involved in aviation, perhaps you (or anyone else) can 
tell me more about
av gas. I've heard of 106 av gas, but someone told me that the octane
rating system for this is different than for regular gas and that it in fact
is lower octane than good pump gas. Truth or bullshit?

Subject: 4 Stroke Supertrapp question
Keywords: XR200, Supertrapp
Date: 9 Nov 92 22:39:42 GMT
Organization: Boeing Computer Services, Seattle

I have been considering winter time projects on my 1984 Honda
XR200.  I have put up with hard starting and a tendency to
foul plugs for long enough (I've had the bike for two years).
So, I thought I would go with a better (than stock) air filter,
and re-jet the carbs (I'm wondering if a previous owner had
changed jets for power, and created the plug fouling).  

Then, a local bike shop suggested the Supertrapp exhaust, and the
addition of extra plates to become more free-flowing.  The 
extra plates would require new jets (or it would run lean),	
but since mine is running rich, I could tune the exhaust much
easier than changing jets.

My question is Has anyone else tried this??  It sounds good on      
paper, but I would like to hear if anyone has tried this!

The bike is bored  and the heads are polished.  All in all it
has been a good ride except for the fouling and starting difficulty.
Any suggestions for Air Filter and Winter project Modifications 
will be welcome!

Hell ride, HELL RIDE!  Mark I'll have you know that I am the Master of the
Nasty Trails from Hell.  Just ask Andy, every time I lead I end up finding the
worst trails within 100 square miles and then I get the pleasure of having 
everyone following me complain.  It's not that I do it on purpose, it just ends
up that way.  Anyway, good luck this weekend.  I'm sending my bike with Andy 
and Todd just in case they break that their $150 isn't wasted.  I really wanted
to go, but my $150 needs to go back into my bike.

  Someone had put fear to me after I read the article that certain types
  of ATF would damage the engine (seals maybe?).  Could you think of any
  type brand that would do such damage?  If not, I'm going to drain the 
  20W50 and pour in Dextron II if I can find it otherwise Ford ATF. 

> 	As for running 20W50, it's a bit heavy isn't it?

  Yes it is. My bottom end was newly rebuilt (by default since I busted
  the case).  I think the proshop must have suggested it for breakin.  Mike,
  Andy and I swapped scoots one day and they drew to my attention that
  the clutch is a little weak i.e.(High revs with clutchwork but no roost).
  So before I went and spent $70 on a new clutch, I thought I would make 
  sure the 20W50 was causing the problem.

  I plan to race a couple of motos this Sunday with the ATF.  I'll let
  you know if I could tell any difference.  Gawd, I hope it doesn't
  explode or something!  If I dont place after the hell rides that Andy 
  and Mike have put me through, I might just explode.

Going all the way to Febuary and the 1st race of the 1992 cross-county season.
My buddy Todd picked up his brand new '92 YZ250 on a Friday before the race.
He was really proud of it and rightly so as it was a good looking bike.  Well
we headed off to Whitney and the sky just looks worse and worse.  When we 
arrived  Saturday afternoon it had rained and the pits were very, very muddy.
We were forced to park near the entrance to the pits.  It was a low area near 
a power outlet.  Todd still had to break the bike in, but was not at all happy
about the conditions.  Todd decided to go ahead and ride.  I was leary myself.
Todd and I were puting around and he was leading. (I was still on my CR125)  
Todd decided to take a trail and of course I followed.  This trail turned into
a very steep rock hill.  Todd proceded to crash as the rocks were very 
slippery.  I layed my bike down to avoid Todd and his NEW REVING TO THE MOON 
WITH LESS THAN 20 MINUTES ON IT bike.  I jumped up and hit his kill switch.  
Needlesss to say Todd was pissed.
 
I rained all night before the race.  Conditions couldn't have been worse as for
Whitney's cross country course is extreamly rocky.  Now it was muddy and
covered slick rocky up/down hills and deep water crossings.  It sucked!  Todd 
raced the Morning race.  He broke his new Thor armor on the first lap.  He
was doing well until he ran out of gas.  The float stuck and drained his his
tank.  He thought that I did not put in enough gas when he pitted. 

I ran the afternoon race.  I did OK until both my grips came loose and I could
hardly give the bike any throttle.  I to DNF'd.  The campsite we chose was a
swamp because of the heavy rain Saturday night.  We had a hardtime moving the 
pop-up camper becuase of the mud.  It was the worst race weekend that I have
ever encountered.

I'm sure that it can be topped!!!!

  If anyone has an tired/dead/retired one of these lying around
