Different CDI Units
Posted October 04, 2005 - 11:28 AM
I have what is basically a 2003 motor and wiring harness with a modified 2005 crankshaft in a SuperKart. The installation of the upgraded crank required changing the rotor and #3 starter one way gear. The motor runs, but we have had gremlins. I was curious if differences in the CDI unit could be causing issues.
Any help would be greatly appreciated.

Basically, the CDI's for 2003-2005 from Yamaha are essentially the same (they might have some slight differences in the curves). Vortex offers one unit with 10 built in curves to serve all those years and it will interchange with the stock units. Besides the multiple curves (one is stock and models a YZ) the standard unit ups the rev limiter to 11,700 RPM and can be reprogrammed to different settings for an additional charge.
