The result of me leaving my scooter to sit for four months

What I'd do... charge the battery, check the voltage on both sides of the starter relay when trying to start it. Check the voltage at the starter connection. You need full battery current to the starter this includes the grounding system to the starter. Use a wiring diagram and a multimeter to find the problem. Never has it been so easy to learn to fix things as it is now. The internet, Youtube and forums like this, it's all at your fingertips.
