With a carb syncing tool. Its used to measure vacuum. You can find a guide online on how to build your own home made one if you want, or buy one (not worth it) or go to a shop.

Some people swear by syncing here... I've never in years needed to sync and I tinkered with my carbs 50 times. All it does is put each cylinder in sync by fine tuning the throttle plates, which just smooths out your idle.

That means they were dirty.

After you empty your float bowls it some times takes 30-60 seconds of turning the engine over until it starts firing again.

Another thing just to not confuse people.

"turn over" is what happens when you hit the ignition and hear the engine moving. If it is not turning over, then you get silence.

If you haven't given it a minute of cranking to refill your float bowls, do so. If then, it still never fires, then there is another problem. W/o removing the carbs, open the float drain screw momentarily to check if there is fuel in the bowls. If not, you are not getting fuel to carbs, if so then you probably aren't getting spark.

Even with horrible tuning, the bike should show signs of life, as if it were trying to fire start up.

Are you GETTING spark? New plugs won't fix anything if your coils are bad. Is fuel getting to the carbs in the first place? Open the bowls and see if gas comes out. If yes and yes, then your problem is still carb-related. Pull out all the jets and visually confirm they are clear with a flashlight. The starter jets can clog VERY easily, and its VERY difficult to tell if they are clear.

if you've loosened both bolts on each boot, then you're not pulling hard enough. It takes a ton of force for the first time if they haven't been off in a while. I thought I was gonna break something too, but it took a bit more than I was putting in it.

+1. They're awful. The first couple of times it usually takes me two people rocking it back and forth and pulling.
