Ac CDI or DC cdi
 

How do I know which CDI I have? I know it is a 5 wire.
Thanks

Others will chime in on the technical stuff but I went on Amazon and found the exact connector(s) to the one I had to replace.

Did u get a performance CDI and did it make a difference? The technical stuff is pretty straight forward when I ended up on a better web page

Generally speaking if there are two wires attached to the two prong connector it’s an ac cdi ,and if there is only one wire it’s a dc cdi .If you can turn your headlight on without the engine running ,you have a dc system .There are exceptions but this is a good start to figuring it out

Sounds like DC
The 2 wire connector does it have a black only wire? That’s 12v DC with ignition on?

If that wire is red n white then I’d expect a black n yellow with it
Black n yellow is the coil wire red n yellow is AC with about 75v AC while running or cranking
That info gives you enough to determine what you have

My cdi has one white plastic clip with 6 available spots, 5 are filled with wires. I will do some testing tonight. I am going to hijack my own thread.......what is the tool called that stops the clutch from spinning? I am trying to remove the center bolt.

I assume you're talking about the flywheel, not the clutch. I use a cheap nylon strap wrench just like this one. Works great. It's described to be an oil filter wrench but it works great for griping the flywheel. An impact wrench would to the trick also.

Thanks for all the help

my bad, that is the clutch. You can stick a penny where the gears mesh to keep the clutch from turning, the penny is softer than the gears so it wont damage the gears.

Ac/dc cdi
 

Check on youtube…. there is a good video on this.... the real test is... check the ignition wire and if the power goes off and on when you turn the ignition switch,.. then it is a dc cdi

clutch nut
 

use a tool to turn this... as it makes it easy... no tool... just a sharp center punch or so... check out the tool on ebay…
