The minibike isn't legal for riding on the street, which is where the smog laws come into play, correct?...so it really doesn't matter as long as you are riding off road. If you are on the street, you risk getting the bike confiscated anyway, so I would think that smog legal or not, you lose the bike. AFAIK, Harbor Freight sells 'CA Certified' engines in CA if I recall correctly. They usually have a different item number, but are basically the same thing. Then again, if you are riding off road, I doubt you'll get pulled over for a smog check. Hmmm, it is CA though... :wink: Hope it works out for you.
