everytime i had leaking exhaust when it was idling and i give it some throttle i could see a bit of exhaust coming out of the exhaust port were the head pipe is.I guess you could have a leak but it would be pretty small not see any exhaust coming out atleast thats what i noticed every time i had a leak
I never saw any exhaust coming out. But those gasket look to me like they were leaking, at least at some time. I have less than 2k on the bike. I did go over the bike after the less than stellar 500 mile service. I did snug up those exhaust nuts, a fair amount. The lloydz gaskets seem to be much better.
