Hit or miss starting problem By raford3 (Read 1,824 times)

My CDI is 6 wire and I think it's DC. It's got spark. I think you're on to something with the functioning of the stator. That's why it kicks easily and won't start with the current draw caused by the starter when the battery is weak. I think I had an ah ha experience now I need to verify. Thanks for the info KZ1000ST. Thanks for the explanation Sprocket.

I do not think your CDI is DC some have TWO ground wires going to it some only one ground wire.
If your battery is weak the starter will not turn the motor over fast enough for it to start. What is also making it hard to start is the #45 jet it is feeding to much fuel.
Here is a 6 wire AC CDI notice the two ground wires:

That's my CDI box in your pic same wire colors and all. I didn't have much time to fool with it today but I did test the voltages on the battery. It was 12.9v before trying to start and 12.45v after running the starter for 15 seconds. I should have tested it with the starter load on it. The starter cranked vigorously though. So I'm guessing the battery is probably OK.
It used to start with the electric starter but never very easily, I had to play with different throttle openings. Back to the jet change, merde.

Yea Raford3, I believe it is getting to much fuel and flooding the plug. Well hell you can probably verify it crank the sucker and you know it probably won't start then pull the plug. It should be wet.

I have a jet I'm sure. I still have the OEM carb. We'll know something tomorrow.

The pilot jet change did the trick, it's even running faster with the smaller jet and starting no problem with no throttle. Thanks all for the help.

FANTASTIC!! I knew you where looseing power with to much fuel and would be quicker with a smaller jet.
Good job
