Hi everyone, I was wondering if anyone had any info on whether or not a cdi would help, and which one is best.
Thanks for any info........

a CDI will help you have more power coming out of turns , but i asked my dealer ship about one and they said that since its reving the engine it might blow it up. I dont think it will be that much of a problem being a 4 stroke. Dyna makes great CDI boxes.

 

only get a rev box if your nailing the stock rev limiter. it won't help out for power.
