Money Pit - 1998 - 2002 CARB

Hi guys,

my WR400 98 model. (i know its old) has had a bit of a rough time of late and has just had a full engine rebuild, on putting the bike backtogether i found the slider cracked! (second carb iv had), anyway approx £600 ($1200) later im stiill not riding.

anyways iv found a 2002 WR 426 carb for a bargain price nearly new?

Will it fit ?

Will it be a pain to get the fueling right as my bike is a 400?

Does the slider go on the 2002 ones?

Cheers for you help



yes, that carb will work. you will have to rejet it.

why didnt you just replace the part not the carb?

Part = £100 from yamaha

Carb = £50 from ebay

will the jets from my 400 carb work?

we found tat the post 2000 fcr carbs r better for the wr4,

my son bgt a fcr3 wifout any rejetting,


iv seen these but trying to get hold of one in the UK is impssible !!!
