Had the same issue. After 42 MPH it start cutting out and dies. Take it to the dealer and it was repaired and returned to me. After taking it to the road, immediately it repeat the problem. The scooter goes back to the shop and finally the mechanic explain it was a cable on the fuel injector. They ordered.
Will update when scooter is repaired.
Good find for your mechanic!
Hope that fixes it.
Cyclepedia.com technician suggested that injector wire might be the problem with certain Like200i issues we've seen here.
Kind of hard to do much more than a visual check for most of us.
And, welcome to the forum!
