I've ridden my buddies 39FCR equipped 440EX quite a bit. The only complaint him and I have is that the thumb throttle is a little stiffer and makes your thumb tired faster. However the instant throttle response more than makes up for that.
2001 Raptor - Kenz built 727
2007 Raptor 700 - GYTR intake, PCIII, and LTE's
2006 F350 - lifted with 35's on 20's, MBRP 4 inch turbo-back, Innovative Diesel tuned

2 wheels or 4 wheels?
The only thing I can think is the price!This carb is great on the trail because of the acceclartor pump. You might be thinking of the Lectorn carb.
2002 KTM 400 EXC, this bike is awsome!
Quads I use to own:
FDO 463ex, Gas Gas 300, Gas Gas 450, Rancher, Yamaha Warrior, ATC Big Red.
If you can't afford to fix it or replace it, don't ask to ride it!

The FCR carb works great on the trail. I have been running mine for over two years and love it.

The FCR41 also works great on tight trails and "hilly" terrain. Stick with the 39 though, unless it's a real big motor with a lot of compression. "Bang for the buck" cost of the FCR makes it much better than most other mods.

Id pay for a 38 and bore it to a 39... 38's are like 200 bucks cheaper

I have to be honest - I'm not completely thrilled with my FCR 39. There is a distinct bog on it when I go from near idle to wide open that I have not been able to get rid of. It is a problem for me when I am running in very tight woods - I really have to feather the clutch to get it going.
I've done a lot of reading and most people say that the bog is just a fact of life on the FCR. If you don't do a lot of lugging on tight trails you'll likely never notice it, but I've actually taken mine off my machine until I can figure out a way to make things better.
Just my opinion.

call colby at C&D and get the new fuel screw adj. if u can get that dialed in right, it will almot eliminate that hesitation completely. and it wont be noticeable. i think itd 20 + shipping

Yeah, I've got one of those extended screws on the way. I'm sure it will help some, but I've already tried adjusting the existing screw in 1/4 increments from 1 turn to 5 with no real improvement. I've also tried going up to a 52 pilot, but again no love... I think I'm just cursed!

The bog is NOT a fact of life. It can be adjusted out (with patience). I mostly trail ride also and would have "thrown it out the window" if there was an incurable bog off idle.
