Why would you "put synthetic in it --no reason just what auto parts store had availble." ?
You should let it break in a bit first. Especially where you said it wouldn't do 70MPH. It
will still break in just very slowly. I had a truck once that took 40000 miles to break in
but that was because I put slick 50 in it at 2000 miles!
I'm very interested in one of these but wonder what top speed to expect and how
the mileage is...
They can get 110 MPG but that might be the 125cc with the auto stop. Not sure
why they can't sell them with that here. It adds about 10 MPG! I wonder if you can add
it back on?
70 MPH would be nice...
