I've been looking for a 4-stroke 50cc engine that doesn't look like it came from a weed whacker. Florida has some stupid laws that say displacement must be less than 50cc and it can't be a manual transmission, but I still want some speed and power (I'm a big guy and there are some steep hills nearby). Anyway I found an old thread here, http://motorbicycling.com/showthread.php?t=19630 but it seems like none of those suggestions are available anymore. I was wondering if anyone has used this http://www.monsterscooterparts.com/...EQ12qiYg_wHawlS1l3DHYIIjiOmNGqJOgMhoCP2Hw_wcB before or has any other leads on a good looking 50cc auto (sub $400). Thanks in advance.
