How Automobiles Work

Hello friends, I’m Casey
Greseth, motorcycle enthusiast, self-taught mechanic, amateur bike
builder and also a Field Trainer for BG Products. Now I’ve put together a number
of motorcycles over the years. It’s been a lot of trial and error and when it
comes to things like cleaning carburetors, what I’ve learned is I only
want to do it once. From that point forward I’ll do whatever it takes to not
have to go through that headache again. So what I want to show you today is some
of the time-tested solutions that BG offers to just make your life a little
bit easier and help you protect your investment from the harmful effects of
engine oil deposits and fuel system related issues. Motorcycles and ATVs have changed a lot over the years, you know just take a look at a couple behind me
here. We went from a simple single overhead cam carbureted engine to a
highly tuned fuel-injected vehicle. What’s happened is as we’ve seen an
advent in the technologies that were kind of tested and standardized in the
automotive industry are now making their ways into the power sports industry. The
things that we’re specifically talking about are low tension piston rings,
variable valve timing and gasoline direct injection all of which are
designed to help you get the best power of performance out of the smallest sized
engine possible and give you a clean emissions and better fuel economy.
Now the flipside of that coin is that they bring with them some very specific
problems. Problems that we’ve become accustomed to dealing with in the
automotive realm things like intake valve build-up combustion chamber
deposits and oil consumption are really starting to plague a lot of our power
sports shops around the country. Now luckily BG has some you know kind of
time-tested materials that are that are really helped to control that deposit
buildup and help you get the most out of your vehicle. So let’s start with a
product we call EPR. Now the deposits that form in the engine as oil
deteriorates they’re a petroleum-based resiny, sticky varnish and without you
know disassembling the engine and getting some sort of manual cleaning on
it or there’s really no good way to get rid of them. Well that’s where
EPR® comes in. EPR® is an oil-based cleaner that we add to the crankcase before we
do an oil change. Now it’s designed to work with heat so
proper runtime is essential but as that EPR® heats up it starts to soak in to the
face of those deposits. What it essentially does is it will liquefy
those deposits and puts them in suspension in the old fluid. That allows
us to drain them out along with the old oil and it really does a good job of
cleaning up deposits inside the engine. So what’s your left with when it’s all
said and done are nice clean metal surfaces. Not only that, but the deposits
that we removed from those surfaces, EPR® is able to hold them in suspension in
the old oil. So there’s no chunks, there’s no smudging or anything like that. So not
only is this an effective way of cleaning injured surfaces it’s also a
way that’s safe for your bike or ATV. So that’s our clean up product. Let’s talk
about what we can do to prevent those deposits going forward and that process
revolves around EPC or Engine Performance Concentrate. Now oils have
come a long way, especially in the power sports industry and there are a number
of great manufacturer oils that are perfect for protecting your bike from
wear and tear under normal conditions. Now to illustrate those conditions we’re
gonna use this thing here. This is a Timken load test machine essentially what it is
it’s a spinning lathe connected to an electric motor. We’ve got a little roller
bearing attached to a torque wrench here. What that allows us to do is to
visualize the effects of friction in a controlled environment. Now we’re going to go ahead and add some engine oil to our fluid bowl until we’ve got a thin film of lubrication over the
top of that race surface. Now oil is designed to really sink into the
pores of those metal surfaces and basically create a buffer allowing those
two objects to slide past each other in a way that minimizes heat friction and
wear. Now you can see that while the oil does
provide a degree of protection for that surface around the 350 inch pound mark
is when we start to run into trouble. At that point we’re putting enough pressure
on those two surfaces to push that lubricant out from between them. We’ve
essentially got metal on metal contact at that point and the result is friction
heat and wear and you can see it does a nasty job of scoring up those metal
surfaces. Now we’re gonna flip this over start fresh and see how that oil can perform with a
little EPC. Now EPC is more or less a concentrated additive package for motor
oil. A good way of thinking about it is kind of like a centrum vitamin, a
concentrated dose of all the essential components that your oil needs
in order to protect your vehicle. What that means for your engine is
consistent lubrication, reduce friction and ultimately reduce wear. Whereas before we were locking up at the
350 pound mark, we’re still spinning nice and free and there’s a big reduction in
noise. Let’s take it up a notch 400 450 500 550 600 completely off the scale. Now that’s
great but what does that mean for the metal components inside your engine.
Let’s take a look. So here was our score mark with just standard motor oil right
take a look at the score mark with oil and EPC keeping in mind that we put over
triple the amount of pressure on that surface and still it offers that kind of
protection to your engine. So what we’re doing here with EPC is essentially
making sure that you just have proper lubrication even under the most extreme
circumstances and that just is a great insurance policy for your vehicle. Now
that we’ve addressed the oil side of our performance problem we really need to
turn our attention to the fuel side. Now testing in the field shows a lot of
inconsistencies between the different you know fuels that we get at the pump.
It’s really hard to tell whether or not you’re getting quality gas or something
substandard. Now I would assume that anyone who’s got a carburetor bike like
my little Honda here behind me has had to pull the carbs apart at some point
right and I wouldn’t doubt that you found evidence of oxidized fuel in the
carb bowl. All of us at some point have emptied a
gas tank or or dumped out a you know a little gas can at home and found fuel in
it that looks like this. Alright this fuel is deteriorated, the
paraffins and diolefins in the fuel are starting to fall out and it leaves
behind a lot of resin and varnish on the sides of the fuel system. So all
throughout the carburetor, through our fuel lines and filter element, all the way
towards the fuel injectors themselves in the combustion chamber. Now this is not a good situation but it becomes a lot more complicated once we add heat to the
equation. Those paraffins and diolefins in the
fuel when they get hit with heat the lighter ends of that fuel burns off and
the heavier ends are left behind to form a carbon deposit. Now these are a lot
like the deposits you would find on your intake valves, your injectors, your piston
top and the problem with them is that they’re porous and they’re very
absorbent so they robbed your engine of fuel that’s trying to get into
the combustion chamber. They soaked it up, cause the vehicle to run lean and this
is where a lot of our performance issues start in this fuel system. The problem
with today’s fuel is it just does not have the detergent capabilities to
really clean these deposits up once they form and that’s where 44K® comes in to
play. 44K® is a tank additive fuel cleaner and it’s one of the strongest ones on
the market and what we’re trying to do is turn a tank of regular old gasoline
into a tank of carbon fighting fuel system cleaner. Now what it does is it
soaks in to the face of those hard brittle carbon deposits and it starts to
break apart the bonding agents that hold those carbon molecules together it
softens the deposit so that the fuel wash and the air flowing over top of the
intake valves and the injectors and things like that basically push that
carbon deposit downstream and allow us to just burn it out of the fuel system
safely and effectively. So it is the best choice for removing carbon buildup and
fuel related deposits from the fuel system. So the three products that we’ve
discussed so far EPR® are 44K® and Engine Performance
Concentrate really represent a multi-faceted approach to protecting
your fuel system and engine from carbon buildup and deposits. It really is the
the best way to get the most out of your bike in terms of performance and
efficiency. So the next time you visit your motorcycle dealership or licensed
repair facility ask for the BG Performance Oil Service along with
your oil change. It really is the best thing you can do for your motorcycle.
