Hello, John Talley here with Partzilla.com.
Today we're going to be looking at the fuel delivery system on our 2007 Suzuki GSX-R1000.
What I'm actually going to do is take a look at the pressure, try to determine if it's
in range.
So, let me go grab a couple of tools, get this tank lifted up, and I'll show you how
to get it done.
Alright guys, this is going to be a skill level one.
Really easy to do.
As far as the tools that you're going to need?
Well, gonna need a 5mm Allen, an extension, and a decent ratchet.
Most importantly, you're going to need one of these.
It's a Suzuki fuel pressure tester, and it's actually made up of four different part numbers.
So, when you go to order one, you get a little bit confused, why don't you give us a call
and we can guide you as to the exact part numbers that you need.
Speaking of parts, well, I don't get to sell you any yet.
It depends on what you may or may not find when you're diagnosing your machine.
So, once you've got your tools together, we can go over there and I can show you how to
get it done.
Alright, as you can tell I've already been doing some work on this bike so there isn't
a whole lot that we have to disconnect like moving the seat or taking out this tank bolt.
So, we can just go straight in.
Alright, first thing you want to do is disconnect your fuel lines.
Now keep in mind, if you've had it running recently or if it hasn't been sitting more
than a day or sow, there's probably pressures inside the line.
So you want to have a cloth of some type in your hand, and you squeeze those little white
or gray plastic ears together and then pull.
Alright, this one didn't have any pressure in it so we're good to go.
Just a little bit of fuel leaking out.
Let's go for the other side.
There.
Now, to get the tester on you actually need to remove these two pieces right here.
There's going to be two of them.
They just slide off from the side.
Alright, let's go ahead and get the other one clipped off.
There we go.
Alright, this is the model that Suzuki actually sells and it's the one that you will see at
the dealership.
Now we do sell these, you have to go and buy several different parts that make up the entire
system, so you've got one, two, three, four different part numbers to keep up with if
you want to invest in one.
But, if you're only working on your machine and you're just trying to determine whether
or not you've got 43 PSI, my advice is take it to the dealership, let them do a quick
test on it.
It will not take them long to do it and that'll give you the answers that you're looking for
or at least point you in the right direction as to what could be going on with your machine.
Now what are some of the signs of a lack of pressure?
Well, one, sometimes it won't even start if you've got zero.
But sometimes you can have some pressure that will allow it to run, but it won't run very
well.
Some of the issues that you'll see, it won't want to rev past eight, nine, ten thousand
RPM.
It just kinda falls flat.
What that is usually indicative of is a fuel pump that is working, but it either has a
stopped up fuel filter coming into the bottom of the pump or possibly one of the O-rings
that go up to the pressure regulator, they could be bad or they could be cracked and
that could cause it.
So, we've got it hooked up, and just on initial startup, what we should see is 43 foot-pounds.
Yep, she pumped up to 43 almost exactly and fell off just a little bit because there's
air in the system and that's acting like kind of a big cushion so to speak.
So we'll turn it off, flip her back on.
Alright, this one initially looks like it's doing what it needs to do, but that's just
reaching the pressure.
And that's not too hard of an accomplishment for it to pull off.
Now where the rubber meets the road is can it maintain that pressure when the bike is
under load.
Now, ideally, we would need to strap this thing down to a dyno, get on it, make some
type of get a load into the system and see if it can really maintain that 43 PSI.
What we're going to do just to get an idea of what kind of shape ours is in is we're
going to crank it up and just see if it can maintain a throttle blip, within reason.
If you just brap your throttle real quick, it's going to drop some, but it shouldn't
drop to say half.
So, let's crank it up and see what she can do.
Alright, she's got it at 43.
Honestly guys, that's what we're really looking for, just doing a static test and popping
the throttle a couple of times.
So I can go ahead and tell you that the fuel pump in here, this one's in pretty good shape.
Alright guys, if you're feeling really froggy and want to buy one of these or you've already
taken it to the dealership and they've told you which way to go next, come see us at Partzilla.com
and we can get you taken care of.
If you have any questions or comments, leave them in the section below and I'll do my best
to answer them.
Til next time we just want to say thanks for watching.
