sup i just wanted to know will a 440 kit for a 400ex add alott more power thanks

 

it only adds a lot of power if you throw in a cam and do some porting and polishing. too much power for you. if you want power get an old 2 stroke quad. but thats too much power too. whatever happened to you getting a warrior or mojave? your some little rich kid whos parents buy them whatever they want aren't you?

 

noo its just i love the thrill of powrerrrr
