yes they are
Does someone have the part number? ...
Your best bet would be to call a Suzuki dealer. Here's the link for testing the petcock.

I changed mine because of the stories on here about them failing but it worked fine. Plus, all of my other bikes use a manual petcock. They have a simpler design and are less likely to fail. I look at the Raptor 660 as cheap insurance.
