Yoshimura R77 exhaust system blowing?


New member
Hey guys so i was checking the bike over today and noticed it seemed to be blowing from somewhere on the manifold once i checked the bolts connecting to the engine there was no air i could feel from there, checked the pipes and the connecting piping that wasn't welded seemed to be blowing, when blipping the throttle thou it didn't throw out more air, only when i really blipped it past 7k it pashed more air normal??>
