very cheap part, very easy to fix…most dealers should have the gasket…...did you self-install, or did the dealer install it? If the dealer installed it,t hen they should be back fixing it…..if you installed it, probably not. The thing is, on an XXV, the exhaust nipple is shipped loose, and the installer puts it and the gasket on, if needed (some XXV’s utilize the Top Vent Kit, in which you wouldnt use the exhaust nipple).....so, if the dealer installed it, its his fault….if you installed it, maybe had a torn or kinked gasket, etc…...I think this is an installer issue
