DIO Cylinder Head Dynamics
After market dio heads are all a little different and it is very important
that you have the right plug length for the depth of the cylinder head.
Water cooled heads take a longer plug than the air cooled ones. The point
of this video is just to take your plug and make sure the plug seats well
and is not to deep or too short for your particular head. Remember all the
parts are different and checking them does not cost a dime and could cost a
motor. Dont guess when a question could cost you nothing to ask. RH
Moped Crank Bearing Removal
Just showing how you can use the bearing splitter sold by harbor freight to
replace bearings on your moped crankshaft.
As you can see the Puch e50 crank I was using was rusted as all hell so it
doesn't get much worse then that and I haven't had any difficulty.
Installing main bearings in a Vespa engine
I haven't seen anybody use this method yet. I am too impatient to put
things in the freezer overnight and don't like feeling like I'm in a race
against time to keep the bearing cold. This method obviously works quickly
and easily if you're careful. Playing with a torch and liquid CO2 is
obviously dangerous. Both can cause you quite a bit of pain if you're

Vespa Super 150 Cylinder Removal
In order to troubleshoot a stuck piston I started the process of removing
the cylinder head, cylinder and piston from my scooter to find the source
of the problem. Both the Cylinder and Piston looked good. I found some
metal shavings inside of the crank case which led me to realize that I had
a bigger problem at hand. I will have to take the entire motor apart to
find out where the metal shavings came from. This video only shows the
removal o the cylinder and piston.
DIO Piston Install TIPS
These are some tips on installing or taking off your two stroke pistons
from the crankshaft. Always keep the parts clean and take your time and do
the job right. Remember that the piston always goes on with the arrow on
the piston crown, pointed towards the Exhaust port. Put your rings back on or take
them off with a piston ring expander. Rings are very brittle and can snap
in half, very easily. Line the rings up with the single ring pin in each
slot. Oil the rings and cylinder walls with two stroker oil and carefully
lower the cylinder onto the piston. Use a new base gasket , scraping off
the old one. When changing or working with the cylinder off, stuff the
crankcase around the crank rod to stop foreign debris from entering and
fallin in the crank well. Use a new head gasket every time and torque the
head bolts in a cross-hatch pattern to avoid warping the aluminum head.
Take your spark plug and screw it into the head before installing to make
sure the plug sits flush with the top of the cylinder head chamber.
