Re: new to motorized bikes
Welcome to the forum, jerk (one of my favorite movies). We have a quite a few members already that check in around 3 bills. Being your first build, I would probably go with a two stroke kit with a jackshaft/shift kit to allow you to use your bikes multi-gears to climb hills and fight headwinds. There are also some very durable rack mount kits like the Staton. There are plenty of members on the site from CA that can help you make the motorbike street legal.
