Looking to upgrade my cdi was wondering about good brands pretty cheap. And does a stock 400ex cdi fit on a 300ex and would that upgrade anything?
That should narrow your choices down and make it easier to pick one.back to the CDI question. almost all brands of CDI boxes are made by the same company. Dynatek makes almost all of the ones that are on the market. Big Gun Rev Box is made by Dynatek.
