Hey guys, this is an article from "Honda Service News Dec. 1996"

Question: How do I know when honing is needed and
when it’s not?

Answer: Honing is needed only when the cylinder has
scoring or vertical scratches deep enough to catch your
fingernail. Light scratches that don’t run the full length
of the cylinder don’t need to be removed. Also, don’t
hone if the cylinders are glazed or polished. Neither of
these conditions has much effect on ring seating or
engine break-in. (You don’t need a rough surface to
make the rings seat.)
When you hone, keep a close eye on the bore size
because you can only hone up to the cylinder’s surface
limit. If it doesn’t clean up by the time you reach the
limit, you’ll need to bore all of the cylinders and use
over-sized pistons.

Question: What type of hone should I use?

Answer: Use a rigid hone only. Ammco, Snap-on, and
Sunnen all carry rigid hones. Don’t use a “bottle-brush” or
a spring-type hone; they don’t allow you to keep the
cylinder bore straight and concentric.

Question: What grit or grade should I use?

Answer: Use a 400 to 600-grit fine finishing hone.

Question: What type of lubricant should I use?

Answer: Use honing oil. It acts as a coolant, allows you
to hone faster, produces a controlled finish, and
lengthens the life of the hone. While honing, keep the
cylinder and the hone wet with the oil. In a pinch, you
can use a 50/50 mixture of clean parts cleaning solvent
and clean ATF instead of honing oil, but never hone the
cylinders when they’re dry.

Question: After honing, what’s the correct way to wash
the cylinders?

Answer: In a bucket of hot water, dissolve some laundry
detergent (Tide is a good choice). Then scrub the
cylinder walls with this mixture and a stiff-bristled
brush. After washing the cylinders, rinse them with
clean water, dry them with a lint-free towel, and
immediately spray them with a moisture dissipating oil
such as WD-40. Never clean the cylinders by just
rinsing them or wiping them out; if you do, you won’t be
able to remove all of the cylinder honing debris, and
you’ll probably damage the engine as soon as you start
