i wanted to update my wr400 carb to the fcr2, the one with the red hot start button, due to issues breaking the valve float 3 times. i should have done this a year ago.... anyway for ebay purposes the fcr2 was stock on which models? 2002+ yz426 right? what about other makes, like crf's and ktm's? anyone have a fcr2 to sell??? thanks in advance.
