450R is flying high
i think it has a Keihn 42mm...it's not the flatside like the FCR, the FCR is only 38mm though

Well, I have heard from a couple sources the 450R does not have the FCR. Maybe someone from ATV Action didnt do their homework.

I am refering to the dirt bike not the atv. I am assuming this is the carb they ran on the baja winning machine. My question is why did they change carbs when the rest of the bike appeared relitivly stock? I thought I read some where the carb that the atv was using was comparable to the fcr in performance if this is true why did they switch it?Originally posted by brif

I think, as an engineer, the reason they dont use the FCR is simply $$$. However I have read that the D-Slide carb that is used is 42mm. I think the large size carb is used to get the top end power from this high torque motor setup, yielding an excellent power curve, i think.
The FCR on my 400EX made excellent low end power improvements, but WOT performance should be alot about bore size, i.e. 42mm.
I still wish they put the FCR.
