I was just wondering, again, if you could switch a YFZ 450 into an EFI quad. They do sell EFI at fullthrotlejunkies.com, but just not for the YFZ 450. I e-mailed them and they said that it was possible. What do you guys think. And if the yfz 450 is so great, why didn't yamaha put EFI in it? Just wondering.......

 

This isnt a backyard job and unless you have intimate knowledge of FI systems I wouldnt attempt it. There are enough rumours floating around about an efi yfz that you shouldnt have to wait long anyway.

 

great! so it is possible.

 

ahahahaha
*shakes head*

 

This is the same guy trying to install an aftermarket exhaust from a CBR street bike on his yfz, I wasnt expecting much.
