I am looking for ways to get a few more MPH out of my Beach Cruiser with a 49 CC raw china girl. I know this is probably a subject that has been beaten to death but I am curious what I can do as far as add ons that will get me the five more mph so I can ride in the right lane and not feel like I am holding everyone up. I already have the better spark plug and wire and expansion tube from sick bike parts. I thought I read somewhere here that one can buy a different head from Treatland in San Francisco, a place that sells parts mostly for motor scooters but they also have many options for motorized bikes as well. I wrote to the guy and he said that the Puch 50 and 70 mm heads are the ones most bought and that I should check here in the forum for folks who have actually installed one. The idea is they raise the compression and therefore more power equals more horsepower equals more MPH. Does anyone have any experience with this? Is it worth it? How much do things improve? Is there a downside to doing this?
Look forward to hearing anyone who has tried this.
