This is the blue wire FROM the engine into the cdi. After replacing spark plug and cdi I noticed this. How screwed am I? Engine still won't start.

Do you see strands? If so, cut the bad section out and solder/ shrink wrap it. Might not be a bad idea to do so regardless.

Also, are you getting spark?

you need to find out if you have a spark - if so, it may just be that your motor is full of fuel now from trying to start it with that bad wire before you fixed it

Ill detach the fuel line. I take out the new ngk spark plug I got from bike berry. I place it in the spark,cap and push the bike with the tip of the spark plug on the engine and walk my bike. I see no spark.

if you don't have a meter to check your repaired wire, I'd open the mag cover and just unsolder blue wire and solder a new one on

I'm considering a new motor. I don't know anything about soldering wires and after spending so much already id hate to spend even more. Ill try again in the morning by tying the wire,tighter and securing it with electric tape.

Ok so you replaced the cdi and spark plug, but still nothing? The magneto is another culprit (easily replaced, and cheap), but tell me how you have the kill switch and cdi wired?

And don't just twist the wires together. At the very least, use a butt splice crimp. They're cheap, and can be bought at almost every store.

Soldering is easy and cheap. Especially since you don't exactly have to be neat or precise. Just get a cheap soldering iron and some solder and look at a youtube video on it, you'll figure it out in a few minutes.

On the magneto, has it ever gotten wet? Water kills those magnetos really easily.
