I have a '00 Kinetic Magnum with almost 700 miles...it was hard to keep from going over about 20mph during the break-in period...but be patient! Actually, I cheated and went full throttle at the 296 mile mark!
I use Amsoil in my moped---2-1/2 oz. per gallon, which is the amount that Cosmopolitan Motors (importer) told me to use. If you are unsure of how much oil to add to your gas, call Cosmo and tell them what type you are using and follow their recommendations. Also, Cosmo is very helpful should you encounter any problems.
I bought a locking gas cap from Cosmo after hearing about people adding crap to gas tanks and/or stealing the gas.
My Magnum will go about 30mph or so (25 uphill).
Enjoy your new Kinetic----I think they're one of the coolest looking mopeds around!
