How can i make my 400ex "run with" 426, 440, and 450f's? I was thinking about a 416 kit or a 426 kit but im not sure and i am on a normal budget. It crossed my mind to buy a 416 kit but im not sure who has the best kit out there. what kits do all you guys run and if you got one ......whos is the most reliable.... It also crossed my mind to just buy a new/used 426 thats in good shape and swap my motor for that...but how hard would it be to put a YZ426 motor in a honda 400ex without doing some major mods. Suggest anything that will help....if it helps i run motocross with my bike having shocks, aarms, tires, etc....

Why don't you just put a 440 kit in it?? If you are considering doing an engine swap, I'd say a 440 kit would be alot cheaper!
