Hey guys, I was wondering if anyone could like describe where the engine number for my bike is. It's a FZR 400 3TJ. I'm trying to find which model it is as I'm having issues finding parts. It's a grey import if that helps

Thanks in advance.

They all have the engine number 1WG - not much help is it
The frame number is on the headstock up by your forks.

Parts can be available, sometimes you need to use them from a 600. Other parts are rare so it can be a bit more of a hunt around. You can also use the model code 4DX that was the official import FZR400RR which had a pillion seat and non adjustable suspension.
