So I did a search and couldn’t find an answer to this. I have a 2002 1800. Just got the tank back on it today and went for a ride after filling up. Ran fine. I got home about 50 miles later and parked it. Came back to the garage 30 minutes later and noticed the gurgling sound coming from the tank and a puddle of gas under the tank vent tube under the bike. After looking I saw it suggested that the gurgling was fuel returning to the tank from fpr. It is definitely not cooling system as the sound and the drip goes away as soon as I remove the fuel cap. Any suggestions?
