Will the stock yfz 450 carb(FCR39mm) fit on a 2003 ltz 400. If so would it increase power and what other things would I have to do to it to get it tuned in. Thanks. i do have lots of mods.

 

yes it will fit with very little modification you will need to contact carb parts warehouse and purchase a "Z to fcr throttle cable" and then make it fit. Finding the carb to head boot that fit just rite was my biggest problem but it was well worth it. This is an awesome carb makes a huge difference. When you get it on you will use your stock carb as a doorstop. http://www.carbparts.com/ you have to call them its not on the website.
