Alright, I was checking craigslist and I found this bike for sale. It looks like it would be fun to get it going but I don't know much about 4 stroke engines. The thing is, I already have 2 bikes, what do I need another one for? Still, what a cool frame, that alone has got to be worth the $250 asking price. The ad says "Four stroke custom motorized bike. One of a kind gas tank and modified frame. Top speed 35 mph, no pedaling required to start. Runs but needs some work." Hmmmm, it seems like a super good deal. Will someone please talk me out of this.
