Throttle bodies - Gsxr K5

Recommended Posts

GaryD1971

Hi All. 

I've been given a set of Gsxr K5 throttle bodies to see if they can be made to fit my zetec engine. From what I can see so far, the spacing is 76 - 80 - 76 between the bodies but this isn't a problem as I am going to fabricate my own manifold. The thing I'm concerned about is the fuel rail doesn't have a return on it. The (very knowledgeable) chap I got them off said that modern bikes don't tend to use a return as it makes the fuel hotter and improves the emissions. Would this set up work on a Zetec? Or would I need to change the fuel rail for one with a return (if this is even possible). I am planning on removing the secondary butterflies and the actuator as this is the reason the bodies were given to me, the actuator is faulty. 

Any thoughts from the collective?

I assume its just a standard Tee piece in the fuel line before the fuel pressure regulator? @Chris King - Webmaster and Joint North East AO

Yup. Works perfectly.

If you run from a sumped tank does this mean that you don't need a low pressure pump to feed the high pressure one? 

I've seen a lot of systems that use a separate swirl pot which then needs a low pressure pump to feed through to the high pressure one.

Swirl pot is a better option

here is another diagram from my collection :d

I have both the swirl pot and dead head injection.

But no, you don’t “need” one...
