The real trick here is to tighten one set of four spokes, then skip two sets,
tighten, and just keep working your way around.

TWO-SMOKER IN BAJA
Dear Mr. Know-It-All,
I am planning to realize a
50-year-old dream and haul my
old carcass to Mexico to run the
Baja 1000. We are going to use
a 450 or 501 for the race, but
my question involves my pre-
run bike, a 2009 KTM 300XC-W.
While I intend to completely go
through it front to back, I am
hearing different stories about
two-strokes not running well in Mexico, but not everyone agrees on the reason.
Some have said it is the gas, others that the bike runs too hot for too long,
while still others say it will be fine. Can you give me the straight scoop? Since
it was new, I have run it on Spectro at 52:1 with stock jetting but will make
whatever changes you would recommend. I will only get one shot at this race,
so I really need the old warhorse to work well when it gets there. I will run my
section three or four times. It is going to get some hours put on it. Thank you
Remember, my friend, that for years two-strokes dominated Baja, and as long
as the jetting is set for sea level (critical) and the gearing is tall enough (again,
very important), no problem, except for the fact that you will need to bring U.S.
fuel ( 91 octane), as the Pemex tends to be hit or miss concerning quality and
Dear Mr. Know-It-All,
My mates and I roam the north of Ozzie, which is fairly isolated, and we
seem to have this injector problem arise every now and then. It seems to hap-
pen after you shut down. It won’t start again until the injector is cleaned. KTMs
suffer the most, and we run more filters than Husky’s home-brew kit, and it
doesn’t seem to be dirt, dust or water. It looks like residue in the fuel. Most
of our fuel comes from Singapore these days. Do you blokes have the same
problem stateside? We’ve tried injector cleaner. No good. At the moment we’re
trying fuel stabilizer. I’ve been reading Dirt Bike since way before S.H. strapped
his riding mate to the bonnet of his El Camino, but I can’t find the issue that
has fork settings on an ’ 81 CR430. I weigh about 105 kilos. My mates and I are
awaiting your response so we can give you a shout.

My own personal knowledge, and that crucial data that has been passed onto
me by eloquent, albeit qualified, dirt hounds, says that a fuel stabilizer will help.
When I put the question to the KTM technical honchos, they stood by the fact
that the standard fuel filter “should” be adequate. ❏
