No..........the battery needs to have a good charge or the bike won't start, even with the Kicker...........
Need to identify your charging system.....And ignition system............The reason for ignition system ID is if the bike has factory Electronic Ignition, (TCI), then damage can be done to it if the wrong procedures are done while trouble shooting..............If your battery is going flat then it needs to be load tested and fully charged. The charging system needs to be checked.............
In the pics showing the Reg/Rect the wiring looks to have been modified..........Needs to be checked for proper installation. Again Pics of the parts/wiring.............Fuse box???? what do you have and is it factory or PO wired.........
.
Do you have a manual????
It would pay to do all the IDing of parts and systems before doing to much more other than getting your carbs jetted Synchronized and back on the bike.
Go to the "Tech menu", scroll down to "Maintenance and general Troubleshooting" read the 2 links "Bike wont start" and "Buying Guide" ..........These are a must read for someone with a new bike..........Probably raise a lot of questions but that's alright, just ask...........
