Bike Won't Start - New CDI, Magneto Coil, & Spark Plug Replaced/Installed, Still No Spark

My 100cc 2 stroke motorbike has been giving me trouble lately. Before I went and replaced the CDI, ignition coil, and spark plug, it had some occasional difficulty starting up. I figured swapping out these essential parts would sort things out.

Now guess what? No luck. Despite installing them right and connecting the red and blue cables to their appropriate terminals, the bike ain't producing a single spark when I try to fire it up. I mean, come on! I got compression and fuel, so why in hell isn't it working?!

Have any of you dealt with this kind of BS before? Any ideas?
I know exactly how you feel !!!
Same thing replaced everything except the magnet. Multimeter indicates all parts involved are good and still no spark.
The motor is new and almost broken in.
It's called a Phantom 85 V3 cause approximately 85% chance it wont start.

Literally all Phantom owners here have had zero problems with theirs starting. Only you, and one other member thus far. There are 700 people on my facebook group who got theirs to start. Stop blaming the engine design. I get you're angry, but we aren't going to solve anything like this. Not to mention, you are replying to a thread of a member who is banned from the forums.

Myself and ImpulseRocket have already told you the probable reasons why this happened to you about your Phantom not starting in another thread, rather than bash the bike design whereas no one else seems to be having this problem but YOU, how about we address the issues that Rocket and I saw right off the bat???

Have you even read these responses to your problem before venting your frustration on this thread???...Your feelings are not going to fix your problems...Just saying.

From Rocket:
From Damien:

First off mistake you made was thinking that replacing the Yamaha component sealed CDI purposely designed for the Phantom 85 was a really bright idea, the other would be did you hopefully throw away the Z series plug which is a known problem of no starts and hard starts on almost all other CG bikes and replace it with an NGK-BR6HS gapped at .025...???..It has a well known high failure rate even when people have said it sparks...Once they listened to us and replaced it, they were mostly astounded thet we were right on target about those lousy "Chinesium" spark plugs.

And he was banned by me because he liked to be very demeaning and belittling to others offering their free, volunteer help...lol.
He was one who also replaced everything on his 79/100cc motor before break in as well rather than replacing only one component at a time to see which one was the failure.



And then there were these two posts that were made after he was still not smart enough to get the hint...lol.

Cut the white wire off right at the coil.

Yes take the cover to the magneto of and spin the motor counterclockwise with a drill and socket on the magneto keeper nut and see if you get spark that way. Also make sure the woodruff key on the shaft is properly in place or the fire timing won't be right. I center punch the shaft on each side of the key to hold it in place so the magnet won't pull it out.
