Re: Hi, I'm planning a huge adventure, please help!
hey, almost anything is possible, right? The Briggs motor would be plenty strong enough and up to the task, but the build and setting it up would be a lot of work. There's a few experienced builders here who build Briggs bikes, and their work isn't something you can put together quickly. That's full-on custom stuff for masters of the game, IMHO. Legality-wise, a 148cc is right under the 149cc moped limit in California, just FYI.
Dunno what timeframe you have to build this bike. I'm not qualified to say how long a Briggs build will take. I'll let the masters chime in on that. All I can say is, a kit will install in a weekend if you thought it out completely and have the right parts up front.
