wanting to trade modified cdi box for stock

[2qk4u]

i recently gave my 400ex to my son and a while back i had Mickey Dunlap take the rev limiter out of my cdi box to give me that extra 1000-1500 extra rpm. it has worked great for me because i know when to shift and not to over rev it. my son is only 11 and i dont need him over revving this bike so if anyone is interested in trading there stock one for my modified one i would be interested in doing so. I would like $25 and yours for mine. if interested please post on here or email me at fizzerbill@cox.net.

i really like the modded box its just i dont need my son messing up the bike.

thanks

all yeh just to let you know if you have mickey do this its $100 plus your old one
