Looking for information about ignition system on Gio mini hummer 110. Have intermetent spark problems on new bike. Suspect CDI, just want to know if anyone out there had the same problem. No spark when it gets hot, but spark when cold the next day.

 

Welcome to the forums nat.

I'm going to move this to where you can get an answer.

 

Check out this recent thread:

Look especially for the "no spark" link.

I really doubt it is the CDI. The CDI is mounted way away from the engine in a moving stream of air when your'e riding and doesn't get hot at all unless you stop and sit for a while. And then it still doen't get all that hot. In any case you could test this with a hair dryer to see if it really quits when warm.

Ditto this test on the ignition coil.

The stator really does get hot with the engine. The stator operation can be measured completely with a voltmeter without having to take anything apart. Of course you will need to take your measurements while it is malfunctioning. If the kill switch wiring checks out OK and the CDI and Coil don't quit working with the hair dryer then report back and we'll test the stator out (get a voltmeter ready).

 

I have 2 new gio hummers, neither will maintain a charge in the batteries, I have already changed the batteries, and rectifier. When I put the meter on the battery while the bike is running the numbers go crazy on the meter, cant read anything....if I shut the bike off the meter reads fine??? Please help
