Anyone know where I can find a CDI box for my sons 07 KFX50? I would really like to get his top speed up some. So far I had the little bearing off the transmission removed, I removed the baffle/spark arrestor and opened up the throttle screw. It's so much better since all thats been done but its time for more. Thanks in advance for your help and advise.

 

Returned yea a PM !
