	I'm not sure of the exact chemical changes that occur, but in a

	them out for a ride....

	If I get the chance, I'll have a word with a mate that works for

Next Friday, November 13, I'm driving up to Koosharem, Utah to check
out the Piute Trail and the riding in the Fish Lake area.  Our trail
riding group is planning to ride the Piute Trail next Memorial Day,
and I'm doing some of the advance scouting now.  I really don't plan
to get up into the high country, because the Forest Service has told
me that they're snowed in already.  But, I should be able to poke my
nose up a trail or two.

The Piute is advertised as a 200 mile ATV road/trail system.  The
pictures in the brochures show fairly substantial roads.  The FS
recreation guy has told me that there are plenty of opportunities for
all types of trail riding, from easy to expert class.  The FS map and
the Piute map both show trails paralleling the ATV route, but I have
no way of determining their degree of difficulty.  In the ideal
situation, I would like to see many alternates at all levels of
difficulty.  And if the main ATV system is indeed roads, then I would
hope that trails would be available as alternates at all parts of the
loop.  Of course, we would tolerate the roads that go into the towns
(for gas, food, lodging).

Has anyone ridden the Piute Trail or the Fish Lake Area?  How about
other parts of the Fish Lake National Forest or the Dixie NF?
Please e-mail me at ramz@lanl.gov with any information you have.

    Let's here it for Bul's !  To bad Senor Bulto was forced  into not

    There is still no  better  trail  bike  than the 350  Alpina,  the

    As for parts, the primier parts supplier is Hugh's in Craryville,
    N.Y.

    Send me you FAX number and I'll send you an article  out of one of
    the bike  magazines  who did an article  on Hugh.  In short he has
    bought  out  many  (most?)  of the  old  suppliers  inventorys  of
    Bultaco parts and has a more complete and comprehensive  inventory
    now than any of the  ex-Bultaco  dealers.  I've got five old Bul's
    myself  (250  and  350  Alpina's,  3  Sherpa's)  for  which I have
    absolutly no problems getting parts and advice from Hugh.

    I also understand that Hugh has both new and re-conditioned Bul's.
    The  article  states that he has almost at least one each of every
    model that  Bultaco  ever built.  That's a lot of bikes !  This is
    his  specialty.  He  spends  several  weeks  each  year  traveling
    specifically  to buy Bul parts  and has made  many old Bul  owners
    happy by  actually  buying  their old  bikes.  Hugh also does most

    Bultaco's.

  Just a colorful example that I'd might add to the dares list.  No trip in

  I would dare you to do the 100' piece-wise vertical rock climb across from

In a recent posting (which has expired, so please excuse
any misquotes), someone questioned the logic of kicking 
the bike after TDC of power stroke. This agrees with 
when Yamaha would have you kick the bike, as it is at the
end of the power stroke that the kick indicator comes into
view on the XT/TT.  

As someone else already pointed out, this gives a fresh fuel
charge to the cylinder. If the bike has no battery (ie TT),
it also gives the "charging" coil a chance to build a good
field before the spark is needed.

The writer also mentioned that you could discern the wrong 
TDC because of the auto-decompressor. I don't know how these 
things work, but it doesn't matter, since both valves are
open at the wrong TDC anyway. Remember , the exhaust valve is 
still closing, and the intake has already begun to open.

 
The only big four stroke I've had trouble starting was the 
can-am 560 rotax. Couldn't get the knack of kicking such a 
big bike with a left side kick lever.

An appropriate first topic to put an oar in the water (or is that a knobby
in the mud) of rec.moto.dirt.  Background: I own an airplane which has
FAA approval for use of automotive gasoline; started reading this group
because my 14 year old son is a dirt bike fanatic who talked me into
bankrolling an XR100 followed by an XR250R followed by a *second* XR250R
for me to ride along...also picked up a Yamaha TW200 dual sport (don't
ask :-( ).  He really wants a CR250 but dad thinks the noise is too much...

Anyway, aviation octane ratings are indeed determined by different methods
than auto fuel, but the difference results in lower grade avgas corresponding
to higher grade autogas: e.g., 80 octane avgas most closely resembles
87 octane autogas.  For the most widely used aviation fuel (100 octane
Low Lead) there is no corresponding auto fuel--it would be in the 110
octane range).  This is a problem for the aviation community, for EPA has
proposed removing lead from all motor fuels, and there is no economical
replacement for tetraethyl lead to create fuels in the 100 octane range.

Avgas has been shown by some FAA testing to be less likely to cause
carburator icing than autogas; this is presumably because autogas has a
much wider range of "high end" distillates (i.e., low molecular weight
hydrocarbons) which evaporate more quickly, and thus cool the surrounding
air more than avgas.  The technical measure of this is vapor pressure
(and for the afficianado it is measured in Reid units)

BTW, does anyone maintain a list of public use trails in the Eastern
US?  We have gotten off road permits for the state of Maryland and know
of six state parks which have ORV trails here (and have ridden at two
of them), but wonder where there might be trails in Pennsylvania, 
and Virginia for starters.  (Now if only I could figure how to get
two XR250's in the back of a Cessna Skylane...)

Rob:  YZ's first same with "monoshocks" in about 1978, I believe.  However, 
the brakes came later. Much later.  That's why their riders went through 
so many pairs of boots.

Glad to here the XT is more fun now.

This was a scary story that brings out an important point.

Now matter how right you think you are, NEVER go riding during hunting season.
I'm not saying this because the hunters have more rights than you do.  I'm
saying it because of stories like this.

I live, ride, and hunt in New Hampshire.  We have certain understandings
about hunting season.  Basically, during deer season you are taking your life
into your hands whenever you go into the woods.  I am a safety conscious 
hunter that would never even consider drawing my gun on someone (unless they
were shooting at me).  However, I have been hunting long enough to know that
not everyone is like me.  There are a lot of pinheads in this world, and a
large percentage of them are hunters.  Even as a fellow hunter with a weapon
in my hand, I am concerned that some joker is gonna pop me.

My advice to anyone is - don't ride during big-game season.  Even though you
have the right, you are putting your life at risk.  Hunters and riders are
persecuted by the same high-and-mighty-self-righteous preservations societies.
As much as riders are persecuted, hunters are persecuted even more.  Thus, a
lot of them get very defensive.

Please don't think that I am justifying what that hunter did!  He was dead
wrong!  But in the deep woods, the only thing that matters is who walks (or
rides) out alive.

Lastly, riding around an area being hunted can scare the deer away, which is
what pisses all these people off.  Good and bad hunters alike do not 
appreciate that.

Around here, hunting season is only 1 month.  I figure I can give up riding
for 1 month out of the year.  This will give me a chance to stud my tires...

The best way to eliminate carb icing is to run aviation gas (av gas)
as it is made to avoid this problem. Mix it 50/50 with your regular gas.
Adding extra heat to the carb will probably help, but takes away some
of the extra power you get running in cold weather. Don't forget to re-jet.
It's not quite as important on the 4 strokes, but the 2 strokes will blow-up
the first time you run summer jetting in -20 conditions.
