it lets the bike build more rpm's...yeah its nice to have on a piped 300...just get one off a 350x...and where the 2 wires plug in switch em and u got a high rpm cdi box...

a high rev cdi does not add power in any way. it lets your quad rev more and longer. not really nessescary when you have a stock motor, but if you got a national motor you might want one to carry that power out a little bit longer
