So I live in Arizona and bought my bike in Arizona and I just found out today that I had the cali model, seeing as how there was the big black box when u took off the left fairing. Now my question is does the reduce any performance at all in any way? I'm pretty sure I can't do anything about it seeing as how there are tubes running everywhere but just wondering

It's easy to remove, and no it doesn't really boost performance by removing it. It's bulky though and nice to be rid of :p
