Greetings all from West TX. I am brand spankin new to the motorized bicycle. I have been building hot rods and motorcycles all my life and stumbled upon a pic of a stretched beach cruiser and fell in love!! I just swapped a neighbor a subwoofer for a Schwinn Stingray so I'm about to build a new toy. So my question is this.........What is the best "engine kit" out there? I will be riding this thing alot this summer and I would rather have a pullstart engine due to the fact I am going to build a set of pegs that will replace the crank assembly. Its pretty flat land where I am. I would like to see 40 mph. I am new to the 2 stroke engines so how much life can I expect out of one of these little things? Thanks yall!!And i'm loving the site......
