Gsxr 750 WP fuel lines to carbs

Recommended Posts

Hello everyone,

 

  I've gotten to the stage of starting the bike following my streetfightering build. It's only on 2 cylinders (3&4). This would suggest the coils are ok.

 

I'm currently using an uxilary fuel tank while I'm testing her out prior to refitting the original fuel tank. I've got this connected to one of the two fuel line that usually would connect to the fuel tap, which has three connections in total. One for vacuum and two for fuel. Could my issue be caused by the fact I'm only using one of the two fuel lines?

Sounds feasible because if both spigots on the carbs for the fuel pipe connections and all four float bowls were interconnected, unless you have plugged the other spigot you'd have wet feet as the fuel would leak out of it.

 

Someone who has better knowledge of the carbs fitted to these new fangled water cooled things then me will be able to confirm this or not.

Well I did plug the other line so not sure if they are interconnected. It seems to make sense to me that the two lines would feed each pair of carbs. Would be good to get it confirmed though.

There's no connection between the number 2 and number 3 float bowls (hopefully this pic shows):

So if they aren't connected then I assume my original prognosis is likely to be correct?

It looks that way.  Connect both spigots to the fuel tank using a t-piece and a bit of fuel hose and it should run on all 4.

yes, you need two lines feeding them carbs. weather one line will be sufficient fuel "tee'd" is another. if yer just balancing them then you should be ok.
