Picco P7 Evo 3 engine repinch.
Picco P7 Evo 3 nitro engine had lost compression, resulting in poor idling
and developed tuning issues.
Remedy repinch, so a custom made compression collar/ring was made from EN9
steel to repinch liner, which was a success.
Hyper video soon to follow final stages of editing video.
Hyper 7.5 liner repinch
Hyper 7.5 4port liner lost compression. Liner repinched with steel collar
made from EN9 bar stock.
Steel collar made on 10inch old Atlas lathe.

just comment or inbox me. if anyone wants to send me some parts for a

How To Clean The Carbon From Top Of Pistons | Using Only Household Products
VISIT THE SITE TO SEE ALL PHOTOS AND VIDEOS ON THIS:
After pulling the GT40 heads from the 5.0 roller motor I discovered that
the tops of the pistons were coated in a thick layer of black carbon
buildup. The cylinder walls (bores) were in great shape with no gouges or
burrs. This left me with 2 options. Option 1 was to disassemble the entire
short block and replace the pistons and parts that were essential after
short block disassembly. Or Option 2 was to try and clean these up and
freshen up the cylinder walls. I chose option 2.
I started by spraying the piston tops with the bathroom cleaner and I let
it soak in for about 10 minutes. Next, I took an SOS or Brillo pad and
soaked it in rubbing alcohol. I started to scrub and scrub until the carbon
began to come off in places. This is a vigorous process that does require
some old fashioned elbow grease but in the end the results are well worth
it. Once all of the carbon was relatively gone off of the flat areas of the
piston I broke out the air grinder with a brass brush for the valve reliefs
The air tools are not essential if you want to take a little extra time
with a brass bristled hand brush. Whatever you do, only use brass! After
all of the carbon was clear I used the steel wool wet with alcohol and
wiped down the cylinder bores and made them shine like new again. I gave
the pistons a final rinse with alcohol and then vigorously oiled the
pistons and the cylinder walls to ensure no surface rust would appear. I
also sprayed them down with Ballistol (gun cleaner all natural)
Anyone can do this with a little time and patients. Just take your time and
you'll love the results!
PICCO BREAK IN! - APPLYING HEAT - IDLING - .26 MAX BIG BLOCK! - HD
I can already tell this engine is going to last quite a long time! The
sleeve around the piston is such a tight fit! this engine was even tighter
than my .21 GO race engine to start!
i cannot wait to get this thing fully broken in so i get to do some bashing
Having some problems with my transmission though :/ and can't use the truck
until i have sorted the problem.
basically the transmission has a 2 speed clutch. and its stuck in second.
this means a throttle it a little and its supper fast! so i will have to
tear it down, maybe make a video, not sure. depends on my finding. and
hopefully itss just dirty and i can clean or maybe just the spring has
broken in the clutch which will make it an easy fix :)
if the worst comes to the worst, i can buy a whole new refurbed trans from
ebay for just under £30! :)
thanks for watching...

How to: Assemble Pistons with Rods
In this quick video I show you how to put together your piston and rod
assembly and get it ready for installation onto the crankshaft.
Here are the current specs for my KA build for those who are interested:
- .020" overbore
- Wiseco .020" over forged pistons
- Eagle H-beam rods
- Stock Crank
- No line boring or honing
- Clevite Main Bearings (In my other video, I showed you how to choose the
proper bearings for your KA. I'm going with the Clevite "standard" bearings
really for experimentation purposes, to see how they hold up.)
