1. They are stored on a covered lift
FANTASTIC

2. He doesn't know if they were winterized or not.
NOT REALLY NECESSARY IF THEY ARE NEWER MODELS

3. Do you even need to do that to those?
NOPE, BUT I LIKE TO CHANGE OIL & FILTER, PUT BATTERY ON A TRICKLE CHARGER AND FOG THE CYLINDERS

4. How could we go about getting them ready for a test ride if they were winterized?
PUT THE KEY IN, CHECK FOR GAS AND PUSH THE START BUTTON

5. Is there an hour meter on them like boats?
MOST NEWER MODELS WILL HAVE THEM. DIGITAL READOUTS WITH A MENU THAT YOU CAN SCROLL THRU TO SEE HOURS, RPM, MPH, DIRECTION, TIMER, ETC
