If I read your post correctly and you move to CA. you have to conform to their laws. If your just going for a visit and your home state where your bike is registered allows mods. you will be fine. CA. or any other state by law can only enforce their smog laws on vehicles registered in their state. Most law enforcement have no idea what other states require.Nothing to do with H-D, but just read Aprillia was fined $275,000 by the smog ploice in Ca. The article said Aprilia allowed dealers to modify the bikes.
Since my bike is modified if I go to Ca. could I be fined?
They won't mess with a out of state registration, They have no idea what your state requires.Don't plan on moving anywhere, just visiting, been to Ca. twice on the bike no hassles,the last time was 2010. Was just wondering if you could be pulled over and checked out.
I am pretty sure the laws in Pa. do not allow modifications to the fuel or exhaust systems, but no one bothers you, at least not yet!
