Piston ring end gap is and important measurement to verify during engine assembly. Do this to ensure that the ring ends won't butt during engine operation and damage the cylinders. Also keeps cylinder pressures more consistent from bore to bore which means better effiiciency and power.

How To: File Piston Ring End-Gaps
In this video, I show you how to file down the piston ring gaps for your
engine. Its something that is definitely do-able on your own with some
patience, and its a pretty useful skill if you like re-building motors.

How to Reseat / Lap Valves (Basic Valve Job)
In this video i'm explaining how to reseat or lap valves in a flathead or
overhead valve engine. Also can be called a valve job, but this is not a
complete valve job. I also used to much valve grinding compound, it does
not require a whole lot. Usually when a engine needs this done is when a
engine has low compression that is found to be leaking around the valves,
or sometimes a engine will backfire do to the valves not closing
completely/properly. Thanks for watching.
Wiseco Piston Inc. - Proper Circlip Installation
Video demonstration of the proper way to install a CW21 Circlip in a Wiseco
4848M09600 Piston used for a 2004-2005 TRX450R. Incorrect installation of
the clip can result in severe engine damage so using the proper
installation method is very important.

Blueprint 106 - Cylinder Bore Inspection
We're close to the end of the 100-level series. In this video I show you
how to measure the cylinder bores using 2 different tools. I compare the
results and illustrate what to look for to determine whether or not your
engine is in-spec.
The block I'm using is a 6-bolt turbo
4g63 from early '92. It has 150,000 miles and this video also serves as a
testimony for the durability of Mitsubishi's cast-iron solid-decked Sirius
I engines. This engine will be cut for a new set of pistons, so these
measurements are needed to determine what size pistons I need to get.
.030" is as far overbored as you should ever take a 4g63. Boring larger
than that will take too much off the side clearances between the cylinder
walls and result in compromised strength from hot spots. The only time
you'll ever need to cut a bigger hole is when an imperfection prevents you
from using the pistons you have, or if you're changing to a larger piston.
If you cut the block to its service limit, you have no room to fix an
imperfection should one develop... so it's best to cut as little as you can
get away with. Boring a cylinder .020" over does not significantly
increase its displacement.
