Z400 Performance CDI

[cubnfrank]

Has anyone changed out their stock CDI unit to an aftermarket high performance CDI on a Z400. If so, how did it work and what brand did you buy? My Z400 has a Yoshimura pipe and a K&N filter. First gear is kinda short, I want to see if I could get more rev's out of this motor

I run the procom cdi and there is a noticable difference, it is a good easy cheap upgrade.  KEN

Toy Doctor, Im ready to try it. I'll look for the procom. There are so many differant brands out there I wondered what the differance was between them
Thanks
