I have an Agility 125 (2007) which I love and has been my faithful companion for the past 6 years. Recently started showing signs of intermittent electrical problems (eg: runs fine for 15-20 mins then stops, sometimes when I'm halfway to work...grr!). I'm working my way back through the main components of the ignition system - coil, CDI, stator, kill-switch, plug, condition and connectivity of all wiring. I'm pretty convinced the CDI is playing-up so started trawling ebay for replacement. Here's where I need advice from you Kings of Kymco;
My CDI is one of those bigger 6-pin DC units - 94mm X 55mm. On eBay looks like the world has moved on and these big units are quite rare (or really expensive). The most common units are now 75mm X 50mm. Many sellers say they are ok for Kymco 125 but are not too specific. ~$20 for the 75mm units. Closer to $80 for the 94mm units.
Has anyone had experience with these cheaper CDI's? If I get the pin pattern right and and make sure it's a DC unit is that all that matters or are there other factors that I need to beware of?
