"wazzzzzzzzzup"? "lata"?(silly kids[img]i/expressions/face-icon-small-disgusted.gif[/img]). All the power you need would be from an fmf powerebomb head, powercore 4, edelbrock kwiksilver carb, K&N jet kit, K&N air filter, and weisco 11:1 piston.[img]i/expressions/face-icon-small-shocked.gif[/img][img]i/expressions/face-icon-small-shocked.gif[/img][img]i/expressions/face-icon-small-shocked.gif[/img][img]i/expressions/face-icon-small-shocked.gif[/img][img]i/expressions/face-icon-small-shocked.gif[/img]

 

yeah those quicksilver carbs really do make a difference. high compressions pistons wake it up too. get a superlight from trinity

 

wazzzzzzzzzzzzup thanks dudes...I have another question..what r the best cams,valve springs etc to get..i want my 400ex reliable, and powerful..thanks dudes

 

well for the best valve springs i would say r&d but you dont need the valve spring unless you use a radical cam and then you have to hardface the rockers. just get a drop in cam( doesnt require springs or hard face) try one from sparks or even get a xr400 cam. they work well for the mid range and help it rev a bit more on top plus they are cheap. i like mine best 100.00 i put in to the quad yet
