As many of you I have Idle Problems with my old FCR carburetor in my 99´ YZ400. I tried everything, new hoses, all new rubberseals, cleaned the carb about 5 times and rejettet. Nothing worked.
Im planing on swapping to a YZ450F Carburetor, but as I´m from germany, the YZ450 carburetors are extremely rare and expensive.
Can I use a FCR39 Carb from a KTM for example? Of course modelyear 2005 and earlier.
I know I will have to rejet the carb and refit all the necessary throttle and hot start cables.
Attached you will find a picture of a FCR39 Carb I could buy. It is a 2010 FCR39 Carb.
