You would have a check engine light on if you had codes, I'm not sure if the older clusters will pull up codes with the buttons- check the owner's manual.
While you may have a new battery, your electrical system may have some issues. pull the contacts where your ground is bolted to the engine block on the right upper rear, and the positive cable leads to the starter relay, starter, etc.. sand them down with fine enery cloth and put dielectric grease on them when you reconnect them. use a generous helping in the lead at the starter in the boot. A little resistance from some corrosion or even a loose connection significantly reduces voltage to the rest of the system causing sytematic faults.
It may just be coincidence on a 11 yr old bike, but the frame slider install may be a culprit- did the engine shift when you removed the original bolt? Two things might have occured- first any number of connectors could have come undone if one end was zip tied to the frame and the other to the motor. I'd start with the crank position sensor at the left case cover and trace it up. the other problem is that a wire may have become pinched between the frame and the block.
next, there are two relays up on the front left of the battery tray. if you check the wiring diagram and trace the wiries, you can figure out which one feeds the ignition system. there are four wires to basic relay- two to the magnetic coil to activate it (a power and ground- one will be switched by the ecu, key swith, or kill switch) a main power supply in and a main power supply out. (i don't know your proficiency level with electronics so excuse me if I am oversimplifying or giving you info you already know)
You can also take the cover off the relay, carefully, and check the contact points to se if they are burnt. if so, sand them down with fine grit emery cloth for a temporary fix unitll you can get new ones from the dealer.
Beyond that- there is way too much to get into on a forum and you should get some face to face help from a local or take it to the dealer.
