Hi,
My throttle cable tube connection (to the switch housing) is knurled, i.e.
http://en.wikipedia.org/wiki/Knurling
My "knurling" is perpendicular to the rotation only, i.e. parallel ridges,
not a crisscross.
What is the best way to loosen and tighten these? Is there a special tool?
My first thought would be to wrap the jaws of pliers or vice-grips with PVC
tape, but maybe there is something special for this?
Thanks.

The obvious answer pre-supposes an opposable thumb. Yell again if that's not
the case.

The issue is that these items are tighter than one can loosen (or tighten)
by hand.
It is a mystery to me why they didn't just use something with a hex shape so
a wrench would fit on it ... why pretend it is designed for a human hand?
Looks like plier jaw covers from Sears ....

No, I don't work for this company, but I recommend their products. (sorry,
couldn't help it)

Hmmm. The locknut on some (many? most?) cable ends generally have a radial
slot cut into them. It's there so you scan stick in a flat blade screwdriver
or popsicle stick for leverage. There's something wrong if the cable thread
is jammed so tight to require pliers. I can't think of a good reason why the
cable housing would require more torque than even arthritic fingers can
apply. Especially on a bike new enough to worry about the finish on the
knurl.
