Who used the GSXR Throttle bodies?
Someone posted pics of what they had done. Looked very nice but for life of me can't remember who.

It was in the diy fuel injection thread.
Im considering buying some, missed out on a few on Ebay .At the moment there are a lot advertised on Ebay by a bike breakers, apparently they imported
a container load from the states due to the demand for them for cars. There are a number of differmt models on there from about £75 buy it now.

Dem's de ones !! Thanks for that.
I just wanted to check them as I've bought a set from ebay, from a gsxr600.

If you need any advice, shout.
The Gixxer 600 ones are a little smaller so will probably need a little more work to get mounted on the DCOE manifold.
Some rubber tubing should fix that, though.

Should be making a custom inlet manifold that will accept them closer together.
Looking into having a couple of flanges laser cut.
Do you have a website ? What are you using for engine and ECU ?
I intend to use them on a 4age with Megasquirt.

Sorry to hi-jack your thread, but are these the ones that vitually fit straight onto an XE?
Cheers

I think it's the Blackbird ones that fit the XE.

When I get round to it, the website will be at www.cantcatchme.net. Will be using an Emerald M3DK for the engine
- was considering MS but have used the Emerald before so is a know quantity. Once running, I may shift the car to MS later and use the Emerald for
something else though.

No. with a bit of respacing, the Gizzer 750 ones fit straight onto a DCOE manifold.

Hi Steve ( or anyone with gsxr bodies )
Just bought some 750 bodies off ebay, look identical to yours 
You wouldn't happen to no what all the little rubber hoses are for?
Thanks Adrian

do these throttle bodies fit straight on a weber 40/45 manifold ? - im building a plenum that will fit a weber pattern , you can fit a a single
throttle body on there , bobs your uncle , or even bubs your uncle .

They will fit if you get the bikes original mount, i didn't 
If you look at Steve's picture ( link page 1 ) you can see them
The beauty of the gsxr bodies is they are 4 individuals held together by a long threaded rod, so you can re space them. As standared they are 80mm
apart

The hoses go to the MAP sensor for throttle vacuum/pressure sensing for ecu.
I also got a set of TBs but likewise didn't get the weber type rubbers. No problem though, just make manifold as tube without flange and use
silicon hose and clamps as joints.
I have the 12mm ali plate, just need some ali tube of right dimension. I think the aerial stockists has some near me, it's used as aerial mast
pole!

Hi Rob
Thanks for the link
As for the hoses, i thought one might be a map sensor but it also goes to a metal cylinder on the fuel rail, is this the pressure reg?
I also have a pair of hoses from the other side of the butterflies that link 2 bodies together
Thanks Adrian

Nope - that's a much better site than mine (he's used words for a start  I'll get round to words, but probably not until the car
is back on the road).
He's also been more adventurous and used the Gixxer 1000 'bodies with twin butterflies (ok he's removed the 2nd pair).
(If anyone's wondering, I believe the secondary butterflies are servo-driven and there to improve low end response. They also make an appearance
on the Gixxer 600 'bodies)
TBH, If I'd gone to the extent of making up my own manifold, I'd probably have saved myself some work and left the spacing of the
'bodies standard. Would perhaps have meant unequal inlet tract lengths hence unequal characteristics of the cylinders, though.

For the plate, you may find that some of the tuning firms will sell you an inlet flange. Alternatively, get the original inlet manifold and introduce
it to Mr Grinder

DensoThingyOnGixxerFuelRail
I presume you mean this Denso Thingy? Is so then I'd assume it is the fuel regulator. As it's connected to the hoses and is part of
the fuel return line, I'd guess it varies the Fuel Pressure according to the Manifold Vacuum. If so, then that's smart but surely it could
be more accurately controlled with FI?
There's a further T-Piece just before it, and I guess the output from that goes to the MAP sensor
*However* an increase in fuel pressure allows the injectors to flow more but be open for the same amount of time. Perhaps it's a mechanism to
squeeze a slightly wider range of fuel delivery out of the injectors?
Can anyone shed any concrete light on this?

Odd...I don't have these on mine...just the 4 joined up ones on the manifold side of the butterflies.

That's the fuel pressure reg alright. It should be on the return to tank with a connection to another device via vacuum tube.
Pressure created by pump in fuel rail is vented back to tank when 'over' or full closed when 'under' pressure. This occurs
usually when under full accelleration and full backed off.
Helps keep a steady fuel pressure.
The 600 bodies I have has the secondary butterflies. The operation of which is unclear but I'm assuming it's a dampening system to
prevent sudden 'snap open' of primaries and a weakening of mixture and stalling hiccup.
I think the stepper type motor is controlled by ecu and provides a smoothing out of the transition when throttle is opened suddenly. Bit like a
damped acceleration enrichment, which can't be accomodated in the FI.
I'm assuming it's a quick device of course but not as quick as to spoil performance.
I intend to remove it from my TBs.
Incidentally what are you doing for cold start enrichment ?
Adrian,
I'll have a look at my Tbs to see if the same connection pipe is there.
You do tend to get funny little things like this which are added to cut out some anomaly or other in the performance at cold, accelerating, or on
overrun etc.

Thanks for confirming its the pressure reg, any idea what presure it runs at?
I'm hoping the standard injectors will be ok, i'm fitting them to my pinto and after head mods hope to see about 160 bhp
As for cold start, mine have an extra connection on the throttle arm that when moved opens the throttle a couple of mm. Would this be for solenoid?

Adrian,
I don't have the extra rubber tube, just the 4 MAP ones.
I don't know what pressure the fuel rail as normal would run at, again I don't have the reg just a dead end rail.
I don't think the injectors would cope with your fuel requirements for 1600cc or above, they are for 600cc bike engine if GSXR 600.
I won't have that problem as I'm using 4age where injectors are in the head, I will blank off the TBs.
Also, Arghhh, no-one mentioned the intermediate throttle balance springs were not held in anything. Spent 30 mins looking for them when they sprung
out.
I've taken the motor/solenoid off the second butterflies. Peculiar item, couldn't make out if it was a solenoid coil or motor.
Hefty magnets on the spindle end and the way it's wound suggested a solenoid.
I now have the TBs stripped and will be making up the relevant blanking plugs.
I also noticed a third cable on underside of crank arm that opens throttle a mm or so. This must be a choke/fast idle cable.
I see on Ebay that prices have doubled for Tbs now!
