hey i was wondering what the best rev box for a 400ex is .. im looking for a low priced one but not something thats so cheap that it breaks the 1st week . ill be running it on a completely stock 03 400ex. i ride roads ( wide open the majority of the time ) , open trails , tight trails, and hills. so i ride a variety of places. im wondering if this would be good for me and if it would give me a little edge in a drag ..


also does it hurt my wheeler in any way other than making it harder to start in the colder weather ( when winter gets here the stock cdi will go back on )

i heard big gun is a good brand ???



any help will be greatly appreciated...thanks alot
