Fnq just in case the thread pitch on that fitting is wrong i took your idea and ordered five 90 degree grease nipples @ 5mm x .8mm pitch thread.As soon as i get them i can run the line outside the cowl and test run the fg57 in it's new home.Should sound good with the shotgun pipes.People reckon it's gonna sound like a harley but i've got my fingers crossed and hope it sounds more like my ducati
