There are new plugs, new gas, and good carbs. What's the best way to check the battery?

Get a new battery and then check the charging voltage.It should be about12.5 volts or more.

Sounds like you may have a couple of minor problems. First, your battery sounds like it lacks enough cranking amps to turn the starter motor and fire the coils. That's why when you use a jump starter, it has enough power to turn the starter and fire the coil creating spark and firing the motor off. Double check the battery acid level as well. If it's low or dry, you'll need to replace the battery. Most part stores can't test a motorcycle battery, so if it's not a new battery, replace it. If it's a fairly new battery, disconnect the battery leads from the bike an trickle charge it overnight.
Second, you may have some water in your fuel tank, or may need to step up your fuel to a 93 octane for a few tank fulls. Are you using your choke when you start the bike up? I have a 83 Yamaha XJ750 Maxim that's cold natured, even when the weather is nice. I have to use the choke on mine for the first start up of the day, after that it runs fine.
Also check the plugs for heavy carbon deposits (rich fuel condition) or browning (indicating a lean condition) and the gap. If you have either condition, you'll need to sync your carbs.

Oh man. did you jump start from a car? Holy crap. I've done that before. Everyone is saying the right thing. How long has that gas been sitting in it?
Take your plugs out and leave them attached to the wires. Then turn out the lights in the garage and crank it for a little light show. Don't shock your crotch, use a flash light. Let us know if you see both spark at the same time on cue.
I did this recently and solved a lot of confusion for myself.

Charge the battery up, run the bike for a while, shut it down and try restarting it. If it restarts ok, then remove one of the battery cables from the battery and let it set for the evening. The next morning, reconnect the cable and if it starts, then you have a bad diode. A diode is merely a one way switch for electricity. I can't remember if your bike has an external alternator sort of like a car's or an internal one on the end of the crankshaft like many older bikes have. Most external alternators have have the diode in the alternator itself while the conventional ones have it in the regulator/rectifier.

battery isn't good enough to provide start voltage and spark at the same time. replace it. rough idle till it's warm means you're not getting enough gas to the amount of air. gotta clean and/or adjust the idle circuit.

What octene fuel you using??????????
Is the battery good???????
is the bike charging properly????
thats where I would start looking.....
then look at ..plugs.... leads... coils... make sure spark is good
then check timing..

I suspect your carbs may need cleaning.
How are your plugs?
