Keihin Carbs

[Blackguywithouta400]

I am trying to find the exact model Keihin Carb used on the 400ex. Is it a FCR,PWK,PWM,PJ? Is the carb a Downdraft or Horizontal? If someone has a part number that would be great too.

The Keihin FCR 39mm carb is the carb for the 400EX. This is the same carb used by racing teams such as Duncan Racing, CT and Curtis Sparks. I have one on my 400EX and its worth every penny, power gains are awesome all through the power band.

The FCR mounts just like the stock carb. I sell the FCR if you have any more questions contact me.

Shane,
How do I get ahold of you. I made up my mind today and I am going with the FCR. I was going to get it through Marcums ATV, but they stopped carring that carb. :(
Let me know, you can email me at O'haraAnthonyJ@JohnDeere.com
Thanks
