I bought a Lance Duke 150 and had nothing but problems from the get. I had purchased it from Scootersfactory.com last year which came with what they call a PDI(predelivery inspection). The pdi is what they do at the Lance Power Sports warehouse before they ship out product. Well, it did not help at all. When I received my Duke150 which looks great but a lot of good it does when you can not get it started after there was a "" PDI done on my unit. I called up scootersfactory.com and did try to help me trouble shoot the issue. Well come to find out it had a bad CDI on the unit and they would have to send out another replacement CDI. I received the CDI after waiting 2 weeks, and when I put it on, I started the unit up and it ran for about 5 seconds and then blew the fuse on the battery. I called them back that same afternoon and said that they would send out another replacement. After receiving a scooter that apparently did not even get a PDI which was extra$$, it took 5 weeks to receive a part that apparently should have been in stock since talking with other scooter manufacturers stating that the CDI is a part that must always be in stock.
