DO NOT RIDE WITH SPOOL'S IN WITH THE STANDARD EXHAUST
........I knew about this problem from a US forum so I usually take my exhaust side spool out before I go for a ride......But today forgot
......The result a big dint in the underside of the exhaust and the whole assembly is loose....Probably from being pushed up and outward's every time it compressed..... 
The people who designed the swingarm and exhaust must work in opposite sides of the kawasaki factory
