gine is trying to turn over is about 9.50. How do I prove its sparking while the spark plug is in the cylinder? I think that's what you

You won't prove it's firing.
It's not gonna.
But, you Can pull the plug wire, shove a plug in it, ground it, hit start.

Won't fire
Battery low.
Start with the most common, easiest problem that can create the symptoms you're seeing

That's some right up work, dude.
Thing is, I can't hear the snap, can't see the fire, and the way I expected it to be was pretty much zero. I don't know if that spark will life one off.
The voltage is supposed to be over ten.
I don't remember what someone said it needs to be exactly.

But that's Definitely a blue arc,

You've heard it spinning without a plug.
And with.

Can you hear a distinct rhythm?
If you have compression the engine loads the starter on compression.

It otta not..
Oil in the plug hole is the cheapest easiest quick check.
Hit start
Listen
Pull plug
Hit start
Listen

If you don't hear a distinct rhythm of the starter add oil in the cylinder, leaving the plug out, in gear, push, prove it'll turn over, then hit the starter,
Could be messy, might wanna rag over the hole.
Might foul the plug,,

Have you proven fuel in the bowl?

Since you worked on the carburetor, are you sure it's working?

Once you have compression, if it doesn't fire,use ether.

The battery needs charged.
At rest 12.4 or five is good.

How much oil should I put down the plug hole? I'm assuming like a small cap full of oil or two? I charged the battery yesterday, put it back in the bike, it had 12.45 volts, sprayed some ether in the back of the carb where the air intake hose usually connects, and tried to start it up. It still didn't wanna start up unfortunately. I also noticed, this bike only has 1600 miles on it, so I would assume the piston and everything should be good.

You might try jumper cables and a car battery (car not running).fuel,compression, & spark = start ,your missing one of the three.

Dude, the air/fuel mix leaves the carburetor and goes into the head where valves open and close. You can't see the piston.

How much of the fogging oil did you use?

Did you ever get it running?

How are you finding the metal shavings?

Do you know anyone who has a scope and can peek into the cylinder?

The rings And cylinder will eat each other without oil.

It's a bummer watching people find us After they have so busily set about trying to start one, especially after so many years of sitting.

IF you have compression it should sound different from one without when the starter is spinning it over.

The compression stroke slows the starter motor and creates a rhythm.

The beauty of it all is
This stuff will fix.

But if you don't have compression, let's try something,
Put enough oil in the cylinder to cover the piston, put it in gear and roll it.

How certain are you that you got TDC Compression when you adjusted the valves?
Are you sure the decompression lever isn't holding a valve open?

It's okay to do things that won't be left that way when you ride it.

You can leave the tank off and unhook the decompression solenoid, if you are in any way uncertain about the valves being closed when they need to be you can open the adjustment.

You have to know if it's making compression and if not, why not.

How much time have the rings been going up and down the cylinder without oil?

You need to eliminate every possible way that a valve could be held open.

The decompression lever needs to be checked
Disconnect the decompression solenoid too

And unless you are 100% certain your valves are right, you might try loosening them off if the decompression doesn't solve it.

Ohhh, you can put it at TDC and put air in the cylinder.
Pull the oil fill plug.
If air comes out you have a
Hole in your piston.
