How to bore a 2-stroke (two stroke) cylinder ATV DIRTBIKE part 2.AVI
PART 2: Students from the Western Iowa Tech Community College Motorcycle
and Powersports Technology Program took a tour of Sioux City Powersports.
Clay Jensen showed the guys how to bore a 2-stroke cylinder. If you would

Deglazing a 2 stroke cylinder
here I am practicing on a old cylinder before I attempt my 3 good Yami
cylinders.This process is called deglazing,clean up the walls and create
crosshatch for better ring seal.You spray some lubricant on the walls first
and run the tool up and down a few times.Then you would wash the cylinder
good with soapy hot water and rinse clean.
Cylinder Head 204 - Porting & Polishing
This is a first-generation 1992 1.6L Hyundai Elantra
small-combustion-chamber head. Thats what it is. It's a J1 engine's
In Cylinder Head 106 I talked about the mainstream porting theories as they
are discussed. We looked at a cylinder head that I have thousands of
dollars of professional work performed on, and a bone-stock
second-generation head that I didn't port.
In this video I just might do something you haven't seen done before. For
some, that may be uncomfortable. The port and polish job I perform here is
what I think will work best for my current build. This is not an extreme
killer port job. What will be different here is where port textures are
concerned, I will be following the advice of a reputable source that will
remain un-named. You're free to port yours differently than I do in this
video, and I give you that out, around the 20 minute marker.
The Hyundai is far from being an ultimate-performance build. It's a $400
box of scraps with nothing but time invested. It's perfect for this video.
My finished product WILL be an improvement over what I had. I don't yet
have access to a flow bench. I still have an achievement to un-lock. As
far as you should be concerned with the techniques I employ... without flow
numbers there is no evidence of what this will do, but we will gather lots
of info from dynp sessions and drag strip time slips. If I could test it on
a flow bench, I would.
There are MANY, and when I say many, I mean thousands of flame war
mongering pirates floating around on rough seas with a hair trigger cannon
finger itching to fire if you port a head any differently than what the
herd mentality says to do while porting a cylinder head. I cover the herd
mentality because it has merit. It's been tested. Tried and true. But I
don't follow it to the letter of the law. I'm definitely not here to
de-bunk it. I would port a cylinder head differently for each build based
on how that engine was used. There's an extremely valid reason why
relating to air speed. It's not the texture of a port that maximizes the
effect of fuel atomization, but the velocity of the air running through an
x or y sized valve. The driving factor in this is the piston speed. I'm
not going to give you the technical information, but will refer you to
information about the Lovell factor. There's a better description of this
in the links below, and even a calculator to help you find your engine's
Why the Lovell factor is important:
Lovell gas factor calculator:
Only people who have flow testing equipment know for sure what really works
and have the capability to produce a perfectly-matched port job for the
ultimate performance build. Those guys know the definition of ultimate,
and THEY are floating below the water Aegis-class submarines ready to blow
your comment up if you don't know what you're talking about. They don't
care if you're an armchair mechanic or a herd of pirates. I will say,
they're zoomed in pretty close on me right now, and I'm expecting to take a
few hits. My work will be tested based on Dyno and drag strip performance,
and the results will be posted here. Fortunately, those kinds of videos
are a WHOLE LOT EASIER TO MAKE!!!
