Re: New 80 cc bike
"Baby steps grasshopper". Just like Cabinfever1977 said. Take it on a short ride, maybe just around the block. Then let it cool before checking all the bolts and connections. Let it cool so you don't strip any threads. Then go alittle further and a little faster. then check everything. You should start to see if you're gonna have any issues. Before you know it you'll be on trips for miles instead if mins.
Have fun. Be safe!
