2008 Tomos Nitro 150cc CDI type

[cwbryant86]

Okay, so I've tried both an ac and a dc generic cdi for gy6 scooters from eBay. Neither would get the bike to start. I'm unsure of how to test for or find one that is for this scooter. (Headlights don't turn on until running so I assumed it was ac) The stock cdi came with a rev limiter that keeps it from going over 50-55 on the speedometer which I'm assuming is 45 real world. I'd like to find one that doesn't have the limiter stock or a performance one that someone knows works for it.

My Nitro 50cc is DC
I use this orange pink cdi off ebay with no rev. limiter.

Most cheap chinese scoots are AC.
The DC ones you often find in karts, ATV's and bigger deluxe scooters, that use electric fuel pumps, like the Burgman copy/clones.

First off, find your CDI, and look at the plug.
I'd say, if the plug is the same it'll most likely work. (I thought 4+2 pin=AC ; 5pin or 6pin = DC, but above user seems to have it reversed... so I don't really know)..
