Looked at the picture several times and from what i remember on my 2007 boulevard, it looked exactly the same. Do not have my bike anymore as i decided to retire from riding at almost 82. Have had the wheel and drive including the brake off many a time over all the years when lubing the drive and yes it always looked the same to me after assembling. So i would not worry, but if you are concerned then drive over to your nearest Suzuki dealer and have them take a look. Or you may know someone else that has a boulevard C50. Take care.
So thanks everyone, from what I heard looks like this plate is normal, I called and e-mailed dealer but got no response back which does not surprise me after having bike serviced, bike came back with grease marks all over my bike, permanent stained turn signal from spilled brake fluid I had changed and more, what ever happened to pride in work and this is a dealer, glad I joined this site to get some straight answers. Thanks
