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?
