Best carb for a 440ex

[trik400ex]

I was just wondering what carb will give me the most overall powergain for my 440ex but still be reliable

[sampleez]

prolly a FCR carb, like off a 450 dirtbike or a yfz

if you got the dough id get a peak performane or eldelbrock, but if your on a budjet do what he said ^^^

[400exredrider]

go with an FCR39mm or FCR40mm both are great carbs

ive heard around the the edelbrocks sometimes can be a lil finiky with there jetting, as in they need to be adjusted alot, and slight changes to flow, or tempurature can affect them greatly

so i would go with the fcr, you should choose the size based on what you ride, smaller for woods or mx, bigger for drag or tt

Who makes "peak perfomance" carbs? From what I know the FCR is higher priced than edlebrock. I have an edlebrock, but If I had to pick, I would probably go with an FCR. I think they work better.

FCR all the way! You pick between 39mm-41mm. All 3 sizes are popular on a 440

whats the stock carb size?

[TC426EX]

35.5mm if Im not mistaken

[trik400ex]

what place would u recomend me buy a FCR 40mm carb

i may have one up forsale here in a few days or so, 275 with cable, and about 12 main jets and 4 pilots

i dunno if they are even around any more, but i remember that they made a carb for a yz250f they soposedly gave the sock motor 3 more horses :eek2: it was an fcr type carb and i think that peak performance was the brand, if it wasnt we prolly wont ever find them
