I very much agree with you because it seems that when 4 minutes have passed and the motorcycle needs to load more gasoline through the action of the vacuum it does not do it or it does not work and it stays dry, I will investigate to see what I findAfter watching your video and the fact that you had to put choke on to get it to try and start again, I am starting to think you have a vacuum issue. Here is a link to a page that helped me when I had running issues with the bike running terrible, plus revving up an down after a bit of warm up.
Go to the "1500 Carb page" and he takes you through a step by step process with pictures.
If I have already done it, cancel the pump and put fuel on it directly, also cancel the vacuum membrane and do the sameIt sounds like the fuel pump. Have you tried putting some fuel into the the carbs to see if it will start again? Possibly a shot of starting fluid.
How's your positive connection on the battery .... that happened to me on my 1986 goldwing aspencade, ..had to many things on the positive side , that wasnt working ....screw came loose , shut my bike right down ...blew fuses too , which i upped the amp on the fuse.I am the owner of a Goldwing 1500 from 89, a few days ago I had a problem when starting, when starting the motorcycle it did it at the moment without problems, everything works perfectly but after two minutes To stop
The day it stopped, it was circulating on a highway and it suddenly failed until it stopped completely, and reviewed carburetors, filters, vacuum circuits, tank cap, vacuum membrane and fuses, I did not find any fault for this to happen, Something similar has happened to any of you? thanks
