Giving up!!!

I should start a new thread, but not just yet...

Basically, I could tell that my plug wire was a little rusty, so I decided to replace the whole ignition coil unit (magneto, plug wire, etc.).

I couldn't get it to fire one time!! I re-adjusted it today to see if it was "too close". No fire. Then I re-adjusted it to be as close as it could be [without rubbing]. No fire.

I take the plug out, and it *is* getting spark. Try again. No fire.

I swap out the old ignition coil unit and I get fire almost right away. Hmm....

It appears to me that both ignition coils are giving off the same amount of spark with the same plug.... so I don't understand why one will fire and the other will not. Makes no sense!!

Any ideas?

sparking

I had the problem with my Skyhawk that my CDI sparked but it did spark as hot as it needed to fire. I replaced the one that came with the new kit with the old one I had laying around and it took right off(until the cheep connections rattled loose)

I later soldered the connections with my old lead based solder and its worked. Just because you have a spark may not be the answer.

Most likely is a bad ground connection at the magneto. Without that then there is no ground path for the ignition coil. On a motorcycle the ignition coil is grounded to the frame, as is the engine. But not so on this engine.
Grind the contact areas with your dremel or sandpaper. There is shelac that needs to be removed there.
If still no spark then see if there is AC voltage at the two wires coming from the stator coil. If I remember right it should be around 50 volts at moderate walking speed.
If it's there then you replaced one crappy chinese cdi/coil with another crappy chinese cdi/coil. From my testing they barely produce enough voltage to spark and so any reduction in performance, for whatever reason, reduces the sytem to a non-functional status. I replaced everything but the stator coil with quality parts a long time ago. I can't believe anyone puts up with this extremely weak link in the system.



I agree with Jaguar on this one, hes the man when it comes to killer ignitions.
I did his KZ80 ignition upgrade and it woke up my engine.
That ground He speaks of is all important, so much so i installed a dedicated ground wire from the engine to the frame just to make sure.

I would buy ten of his CDIs if only they fit on my bike!!

My CDI looks like this... http://www.scooterpart.net/products.php?id=1890

I bought two more from a different online dealer, and have been trying to get one to work at different gaps between the CDI's "pickup" and the magneto. NOTHING WORKS!!! I'd return them both, but the dealer is saying that once installed, no returns.... so I have this Catch-22 Dilemma.

The only real difference that I can see between the "somewhat functional" CDI that I was using and the "new, but non-functional" CDI is that I can just barely see the plug connector spring thingy (because it's got so much rubber that wasn't cut away). On the older, "somewhat functional" CDI, there is no excess rubber, and you can see all kindsa rust/corrosion on that springy connector deally.

I guess I'll have to cut it off if the guy won't take them both back.

A sight that looks interesting

I think this might be neat to look at.http://www.dragonfly75.com/motorbike/index.html

I got the fix for the pick up gap...
I use a regular everyday business card (or 1 on each side) between the pick up and the rotor and tighten it down, then remove the card (or cards) works every time.

This is an EZ fix...

Frustration is the worst enemy of performance.
Next might be ignorance.

It is time to grab a six-pack and a fishing pole.
After a few days, come back and review the advice threads and then proceed with the suitable correction.

Good luck
