Yes, sometimes we just have to love that search feature.
I did a search on California engine kits and came across Bairdco's monster thread about CA laws and how they pertain to the motorized bicyclist. Damn, that was a lot of reading. I must say that the state of CA seems real picky. Though I intend to get the plate and have my bike registered at some point in time, I will make a mental note to stay out of SoCal and Newport Beach in particular until I am legal.
It does seem that Venice Motor Bikes has an engine that they will sell to California residents so I may be going that route.
