I bought a Lance Duke Touring 250 new, and it overheated with only 13 miles on it!! It would appear that the dealer either didn't put enough coolant in it, their was air in the system, or probably both!! Though my northern California dealer has been working hard to get this engine or scooter replaced, Lace Powersports doesn't even seem to be able to support the dealers they have, and it has been three weeks with no engine or replacement scooter in sight!! I believe this system is not adequetly designed, and will cause problems for their owners.
