Does the headlight not illuminate when the engine is running?
Does this scooter not have a spec plate showing which oil to use?
Regular 15W40 works fine for GY6 break-in, but change at around 50, 200, 500 miles to keep the suspended glitter flushed out. One option is to change to
Delo at around 1,000 miles, which has a little more
slick stuff (Zinc & Boron).
