my bike is not registered....I have passed a few cops and shut the engine off, but again, i have passed one or two at full speed and just gotten a wave
It depends on the cop.
this is what i have found on DMV.org, i live/ride by this info,
1) Mopeds
State legislators define a moped as a vehicle fitting all of the following criteria:
* Pedals that allow you to propel the vehicle
* A seat for the rider
* Three or fewer wheels
* Motor of two-brake horsepower or less
* Maximum speed of 30 mph on level ground
* Automatic power-drive system
* Displacement of 50 cc or less (for those with an internal combustion engine)
Mopeds need to be registered at a county tax collector office. The registration fee is $19.10, and you must renew your registration every year. Thankfully, you don't have to pay the $100 initial registration fee.
You'll receive a motorcycle plate for your moped. If you're under 21 and the registration is in your name, your plate will have a distinctive design and color.
Moped drivers need to have at least a Class E driver's license, and be 16 or older to drive a moped on a public road. A motorcycle endorsement isn't required.
You will not be allowed to ride your moped on bike or foot paths. All passengers under 16 must wear a helmet.
Moped drivers aren't required to carry Personal Injury Protection insurance.
Be aware that moped drivers have the same rights and responsibilities as other motorists. And, yes, moped drivers can receive traffic tickets, too.
