Hey, I'm looking to buy a 2007 xb9sx from somebody. The current owner says the last owner gutted the exhaust, but he doesn't know if the inter-active exhaust system is still there and working. How can I tell? This will be the first Buell I own, so I don't exactly know what to look for. I do have a good amount of experience with motorcycles though. By the way, I'm actually really looking for a xb12s to purchase, but can't find any. Any offers?
