Bike idles rough and stutters

Hey guys my names max and i just bought a yamaha fz6 2005 16k miles. The bike was dropped and it was sitting for 5 years. I jump started it and it fired right up. Only problem is battery is completely dead and it idles rough, stalls if i pull in the clutch. Dosent stall if i rev it a bit. It does idle but like i said its a little choppy. When riding the bike the motor def is strong because it runs 100% and i can feel it bc its fuckin fast and sound like its running on all 4. Only problem is in the lower rpms its choppy and also if u hold the throttle at like 4k its a tiny bit choopy. If u roll the throttle tho it run like new. My first thought is the battery that is not giving it enough spark or the injectiors arent at 100%, or even the fuel pump. I think this because when i leave the jump cables on the bike from the car battery the idle isnt as choppy and dosent throw a check engine light. I got a new battery but it still dosent start the bike, all i get is a fast clicks. Somewhere around 6k the check engine light flashes on also but dosent stay on. If anyone can help me it would be much appreciated. If someone has a fb i can send a video of it running. Thx sm!

Jumping a motorcycle battery with a car is not a good idea. Since you do not know the maintenance history I recommend the following:
change plugs, change oil and filter, change air filter, check air box, check stator (motorcycle version of car alternator), drain old gas and put in high octane gas for first tank, clean fuel injectors, do an electrical check of system to make sure no damage was done with car jump, and make sure kick stand safety system is not an issue (if the sensor is bad or acting up, the motorcycle will not start (at least on my 08' FZ6).

Also, check the clutch cable, brakes, all lights, all all fuses and make sure the drop did not damage anything. The idea is to establish a baseline of YOUR MAINTENANCE and of course to get it running.
