Hey Guys, first off let me say what a cool forum this is. I have been on lots of other forums for other hobbies and this one is hands down one of the most informative and friendly I have found. OK so heres my story: Im a bike guy. Love my road bikes & Mtn bikes but mostly my old collectables( Stingrays and Cruisers). I always have a garage full of bikes in various states of restoration.I have had over 100 bikes over the years. I ride them all- no shelf queens that never get ridden. Im NOT a Motor Guy- never have been, but im not afraid to give it a try. I live in Huntington Beach Calif. and my daily commute to work is 10miles all along Pacific Coast Highway- virtually flat the whole way. Im 225lbs if I skip lunch haha. For my 1st Project I want something reliable and sturdy to ride to work a few days a week. If I get the "bug" I can for sure see myself building a board track racer or a cool Cruiser, but that's project #2. For this first attempt- Im thinking of a 4stroke kit and mounting it to an old KHS Mtn Bike I have. theres plenty of room Height wise, but im not sure about pedal clearance. From what I have been reading here- the 4stroke kits seem to more reliable out of the box and run at full speed for a longer period of time. So thats my story. Advice is always appreciated, especially if im way off base in my thinking. Thanks, Ed.
