Got a Batteries Plus near you? you can pick up a maintenance free replacement battery. just give them the make and modelof the bike
Also as stated take fresh gas and pick up a can of Seafoam from Autozone, etc. Drain the tank by removing the fuel line.
All you will need is a pair of needle nose and a short piece of hose. Drain the float bowls on the carbs, small metric allen head. Button everything back up, fill the tank.
Add 3-4 oz of Seafoam.
Make sure you can see oil in the site window on the right side on the engine. Install the battery and fire her up.
The bike may smoke a bit from the Seafoam, that's normal.
Give him the cash and high tail it before he changes his mind. Get her home, change the oil and filter.
Rock and Roll!
