So... first post here. Bike: 1980 cb750f dohc. Have a 4 to 1 kerker megaphone exhaust. pod filters with the jet resized to 110? i forget had it go 1 size up from stock. But onto the problem. Bike runs rough(pod filters i know) but power is there when Im on a straight and I give it some gas to get up there when I'm in 5th gear and hit 5500 rpm this horrible screeching sound happens i always back off the throttle never try to go past it. never tried hitting 5500 in any other gear either. but as soon as I let off its gone. Ill be happy to answer any questions that may help with ideas on what it might be.
