New CDI and coil

[iamteeg]

So which method(s) did you use to determine whether your engine is AC or DC fired? I am scared to use the wrong CDI in my scooter (I read a horrific forum post somewhere regarding basically ruining an engine from using the wrong CDI)...

Thanks,
Tom

You match the plugs with pictures. Also, most are ac and smaller than the dc in physical size. Good dealers will put measurements of cdi in the ad. My 150 I determined was ac, as most are, and I upgraded to one with no rev limiter. I can tell a big difference in take off and at least 5 mph on top end. Still need to check it with gps. Cost me 10 bux.
