So I am having this while riding lately having oil on my rear exhaust near the top whenever I ride I have sat there and revved the engine and watched every little spot but can't find a leak. But every time I ride it's on the exhaust pipe. Can't figure out where it's coming from. Any ideas? Probably just gonna take it in to the shop....also it's not carryover or blown from the airfilter. Bothering me because it can sit stationary being revved and no leaks then I ride 3 miles and it leaks.
