Hi John , after your post , I checked mine. And this screw is the same as yours , 5-6 mm distance .... I try to tighten, was already full tight ... So I think , maybe , when the bike accelerates , decelerates and with heat , maybe the Exhaust system need some "free moving space " , an error with this size could not be possible in my opinion , maybe some flexibility needed in exhaust system ? I don't know ... I will go to the service they can check it ... thanks for sharing !I was double-checking fit with the side case during Mistral exhaust install today and noticed that the main bolt which supports the CAT dead center behind the transmission was backed out around a half inch. That struck me as "odd." It also lacked the telltale yellow paint splash indicating recheck at the factory. I checked it (6mm allen and ratchet) and found that it was indeed loose. It screws into a blind threaded cast boss on the underside of the transmission case. This picture identifies the bolt, already tightened with as much torque as a prudent man would apply, and you can clearly see that the fastener is about 6mm too long for its intended job. (Rear of the bike is the left side of the pic, view from the right side of the bike
I will be removing and replacing it after shortening it appropriately, but it clearly had vibrated about halfway out in just 200 miles or so of riding, so y'all might want to give yours a peep.
