Fuel Injecter?

[firechickenXB9R]

First question is what is the rating for the XB9 and 12R injectors. And second will the 12R injector fit in the 9r? Thanks

 

[BuellPartsGuy]

The fuel injectors are the same on the 9's and 12's

 

[firechickenXB9R]

Well you mean the same fitment? Because i did a little research and found that the 03 XB9R has a 45mm
and the 12R has a 49mm. so will the 12R's fit in the 9R?

 

[BuellPartsGuy]

Well you didnt say what year.....

The year I looked up, they are the same.

 

[firechickenXB9R]

What year did you look up?

 

[firechickenXB9R]

I need more fuel! When i put the cold air/ram air on it it started leaning out on the top end. So now im trying to get more fuel. What is your opinion?

 

[BuellPartsGuy]

You still didn't tell me what year you are dealing with.

I looked at a few different years and the fuel injectors and fuel pumps are all the same. The throttle bodies are different sizes. The 12's are larger.

 

[buell007]

that size is the throttle body not the injector. 45mil on the9 ,49on the 12.the injectors fuel level is comtroled by the ecu. they are the same injector. 99% of all injectors will have the capeabilty of suppling more fuel but only the amount that it is told to by the ecu.[cool]

If you want more fuel for your bike you have no choice but to remap the ECU to provide more fuel to the motor. That is your only choice.

Ya, but there is no one around were i am live that can do that. And can you do the factory ecm?

Get a Remus or Doebeck to piggy back on your stock ECM. If you dont wanna do that you can always get a Race ECM.

 

[firechickenXB9R]

A Remus? I have not seen that one I'll go look for it. thanks

 

[bitter rod]

I am running race ecm...have the lean problem as well. Hmmm

 

[dans03firebolt]

Yes Remus and Doebeck make fuel management controllers for our bikes. Either will work for you.
