1986 VFR 500 has 2 vacuum ports on the fuel pet-cock, I'm hooked up to the bottom port and was running well after I cleaned it. NOW no fuel running from the pet-cock to the carbs. Do both the vacuum ports have to be hooked up to vacuum? If so, where is the upper port hooked up to? Thanxs
Thank you, will try that one. Am I mistaken that the top one is for the main fuel and the bottom port is for the reserve fuel? I started the bike last night and cranked right over but shut off a minute later real quick. I removed the tank and when I remove the fuel line I noticed no fuel in the line leading to the carbs at all. Is there a cleaner or solvent to use that will help the diaphram work easier or better?
