Rev boxs

[redneckrider14]

I dont really know much about them i was wonderin if they are worth the money and are u risking blowing ur motor. How many rpms is a stock 400ex. also what is the best sproket combination for woods ridin and occasional racin. thanks

I feel they are a waist of money. the quads i have seen them on started very hard and also fouled plugs trying to start.

i have a generic one on my 416 and it starts RITE up no problems.. and helped out alot with top end.. before i was hitting the rev limiter constantly

i had an srp rev on mine it went out and i put the stock back on. i had to ride a sunday before i could get another and mi ex is geared 13/39 w/cam an i figured i would be on the limiter all day,well to be totally honest i didnt even notice i had the stocker on and im not gonna buy another.....just my feelin.
