How fast will a 2003 z400 go ? It has a yoshi pipe, k&n filter, and jet kit.

They are scary fast! I once saw a dude's teeth get sucked out of his mouth when he clicked 5th gear! It was awesome!


To answer the question, no faster then stock

I had about the same thing on my KFX and I would say probably 70 to 75 mph.

why does everybody give others such a hard time when others ask how fast a bike goes?
