400EX carbs

[12oclocker]

I've got a 400EX with a wiseco 440 bigbore kit
Anyone know a Flat slide carb that runs well VERTICAL on a 400ex, without flooding.
Or has anyone ever modded a CRF450 carb to fit on a 400EX?
I know the CRF450 carbs will run completely vertical without flooding!

Try a FCR39 off a YFZ450. The stock thumber and cable should work.

yep they work wonders. not only for vertical running?!?! (i'm assuming you drive up cliffs??) but they also give you a good power increase!!
