I just watched Tremontes' video where he installs block off plates.( good video by the way) He went a little deeper than the air filter to install the plates. But I'm a little surprised that so much stuff has to be removed just to get to the air filter. I own an HD Sportster and it takes 2 screws to get to the air filter. Probably a 5 minute job total and that includes several swigs of beer. So I guess I'm spoiled. I had a Honda Magna that the tank had to be removed to get to the air filter, but it didn't have any extra body panels to take off. Just something I never thought of when I bought the bike. I guess it's done this way to keep the bike compact.
