Great
Article. I'm much more interested in this kind of thing than I
am in what color nose-ring is "in" with the Glam
Rock freestyle MX crowd.

Aluminum
smeared on a cylinder sleeve can be removed with Muriatic acid
applied with a swab. It eats the aluminum not the steel and
allows the cyl to be honed with no aluminum stuck in the steel
pores. Be careful not to get any on the aluminum casting.
My IT490
has light 4 corner wear from the Wiseco forged piston crown
down to the bottom of the skirt. Cannot feel with a thumbnail
in the bore but the cross hatch is worn there - reusable bore
and piston in my opinion. I hope it is from worn rings or the
excessive side clearance between the piston and the con rod
which allows the caged needle bearing to wander side to side
leaving the piston free to wobble in the 4 corner axis. Will
try moly coating the piston skirt, thermal coating the crown,
spacers on the wrist pin to remove the excessive gap, and of
course new rings. If they had used 18 x 22 small end bearings
on the small end instead of the 18 x 23 I could have put in
cageless needles from a Rotax sled engine and doubled the
needle count.
I really
like your website, especially Hunky's editorials. Great job.

Excellent
article on preventing, and diagnosing seizures. I LOVE the
technical articles and could stay up all night reading them as
they're very informative.
I am a computer professional and musician. On vacation in 1994 I learned on my brothers XR 500 riding in the San Rafael Swell of Utah. After crashing dozens of times, bloodied and bruised, and finally snapping off the clutch perch I was hooked. My brother wasn't so impressed: "You owe me a new perch and some handlebars - Spodeboy!" A spode is a slow rider, or a rider who is unskilled, often times riding beyond their limits, and is often entertaining to watch.
Most of my haunts are in Colorado and Utah but always on the lookout for new and interesting places to go. I can often be found riding up Left Hand Canyon near Boulder, or Rampart Range near Sedalia, Colorado on my 98 RM 250
