Hi all. Yesterday I was Riding my 83 Goldwing and it was running great. Next day though. I downshift to make a turn and my throttle has no power. My bike kept doing this. And now even with the choke on it won’t get any power. It has a new fuel and air filter. We changed the oil and put sea foam in and are running 93 gas in it. Also it has a new starter. Any ideas why it’s doing this?
