- What's up guys? I am Chase here at Rocky Mountain ATV MC,
coming at you with the power jet carburetor kits
from Lectron Fuel Systems.
So, Lectron Fuel Systems, these guys got started
back in 1974, they come out of Texas
and they specialize in making high performance carburetors.
Now, what's so popular and so unique about these is,
one, they're a direct, bolt-on replacement
for your motorcycle, for your stock carburetor.
And if you look closely, you are going to notice
that there are no jets on this carburetor.
So, this is a self-tuning, self-adjusting carburetor.
So it's gonna self-adjust for things like altitude,
for humidity, for temperature and the way it does that
is it uses their metering rod technology
which we'll talk about more here in just a little bit.
So, these carburetors they really just simplify everything.
No more polyjet, main jet,
jet needle, needle jets, all that.
It is out the window.
So, these are really popular,
make 'em for a lot of different motorcycles
but especially popular for riders
that do big elevation changes on their rides.
For us here in Utah, for example,
we can from 4,000 all the way up to 11,000 feet
or more in a single day.
And so, when you're doing those big elevation changes
this makes it so you don't have to worry
about doing a rejetting your motorcycle.
So, much simpler.
And, I actually have heard a lot of riders
talking about this, this does not come for Lectron,
but a lot of riders say that it does increase
the fuel economy on their motorcycles as well.
Now, we have used these here at Rocky Mountain.
For example, we have a 2017 Husqvarna TE 150.
Now, we were having issues getting
that bike jetted the way that we wanted it.
We tried different jets, different jet kits.
Jets couldn't get it quite right,
so we actually threw on a Lectron carburetor.
If you wanna see that test and how that went
make sure you click on the video.
Needless to say, we were impressed and actually did solve
the jetting issues that we were having.
Now, Lectron Fuel Systems says this is a self-tuning,
self-adjusting carburetor but I do wanna point out
that there are a few adjustments.
There's three actually, three things you can fine tune
and adjust on this.
You're gonna have two external and one internal,
I'll show you that here in a minute.
But, let's just take a look at the carburetor
from the outside and work our way in
so you know what I'm talking about.
So, it's gonna look like your traditional carburetor,
no surprises there, but on the outside you're gonna have,
this is your choke, big black screw there.
You're gonna have your idle screw.
So this is adjustable, just for your idle.
And then here in the front, actually the rear,
'cause its gonna face the air box.
This is gonna be your power jet.
Now, the power jet, you're gonna fine tune that
and what's cool is talking to Lectron Fuel Systems.
These guys say that typically it's no more
than a quarter turn at a time.
So, you don't need to worry about having
to fiddle with this when you're out riding.
It's very small adjustments.
But the power jet, is gonna be for half-throttle or more.
So think of it like a kitchen sink faucet,
when you're half-throttle or more
the power jet is gonna pull fuel from your float bowl
and add more fuel to your mixture and that's how that works.
So, very simple, straightforward, simple to adjust.
But the secret sauce and how these things work,
'cause you're probably wondering how the heck
does this thing self-adjust.
It's gonna be in their metering rod
and that's what I have right here.
So, I've actually taken this one
out of a different carburetor.
So, this is gonna be a slide similar
to what you would see on any other carburetor
but here's the secret sauce.
This is their metering rod, right here.
Now, how this works it's actually really cool,
'cause there's no electronics
it's all just based around physics.
So, the side facing the motor is gonna have a chamfer side
to it and it's gonna have a tapered chamfer
all the way down.
And then the side facing the air box
just has a rounded side.
So there you go, so that's the chamfer,
that's the metering rod.
But, how it works is like,
you gotta think of a rock in a river.
If you've ever seen a rock in a river.
The waters coming down, it hits the rock
and as it gets to the other side you actually see
that water start to come back towards the rock
and you have what they call that eddy on the other side.
So the same principle is here, so as the air comes in
it's gonna hit the round side of this metering rod
and then it's gonna create that eddy on the other side,
on the flat chamfer side.
Now, depending on how strong that eddy is,
so taking into consideration your altitude,
the humidity and the temperature, that's how much fuel
it's gonna pull up the metering rod.
So what's cool about this is you can't use too much fuel
and I think that's why a lot of guys say
that they get better fuel economy.
Is because, it just totally depends on how strong the eddy
is, how much fuel is gonna come up the metering rod.
And that's how it self-tunes and self-adjusts,
is taking those things into consideration.
So, simple and straightforward,
it's actually really brilliant.
I love the idea of the design, very simple.
Now, when it comes to the third adjustment
that I talked about earlier.
So, you're gonna have your air screw,
your idle screw and that power jet.
You can adjust the metering rod as well.
So, typically with the metering rod adjustment,
it's gonna really depend if you have
some modifications done to your bike.
So maybe you've done air box modifications
or you've done an after market exhaust.
You can fine tune this and the way you do it's very simple.
Every Lectron carburetor's gonna come
with their adjustment tool.
So you take this, you just slide it up the metering rod
and as I said, just with that power jet,
usually no more than a quarter turn
at a time is gonna be needed.
So, very fine tuning, very easy to do.
Now, one thing you wanna keep in mind
is once you've adjusted this if you do do a quarter turn,
this chamfer side always needs to be facing the motor.
So, once you've done that, you can actually just turn it
right back to face the motor by just simply compressing in
and rotating it back but it's not gonna mess
with the adjustment that you just made.
So there it is, that is the metering rod.
And again, that is the secret sauce
behind the Lectron Fuel Systems carburetor.
So, if you do big elevation changes
this is gonna be a really good option
because again it's gonna optimize performance
regardless of the elevation change that you are making.
Or maybe you're just not too confident with jetting,
or you just don't like to dabble with it.
This could be a really good option.
So head over to our website at RockyMountainATVMC.com
to pick yours up.
Now, you wanna keep in mind these are machine specific
and they come as a kit, so enter the make,
the model, and the year of your motorcycle
and that will give you the kit
that's gonna give you the parts that are specific
to give you the exact fitment that you are looking for.
