    Newbie with a fuel leak

    Hey Everyone,
    I'm new to the group. I've ridden bikes for almost 20 yrs - even had a R1100R years ago but that bike didn't fit my long legs very well. I recently bought a 2002 R1150RT with 30K miles on the (the bike I should have bought years ago). I love the bike but when I got home from work on it yesterday, I smelled gasoline. I didn't see anything so didn't worry about it. This morning when I cranked it up, it started immediately dripping gas off the bottom of the engine so I shut it off and left it there. It will be this weekend before I can strip off the plastics and take a look. What do you think I'll find? Just trying to prepare myself mentally

    Probably OEM plastic quick disconnects that have finally given up the ghost.

    Replace with metal QDs.

    First off welcome to the MOA Forums.

    Some guesses and things to check:
    - cracked fuel quick disconnect
    - cracked/split fuel line between tank and plastic inlet tube
    - loose fuel line clamps
    - O Rings at fuel injector inlets leaking

    You might have to turn the ignition on to pressurize the fuel rail and lines to find the leak but don't start the bike until you fix this.

    Thanks...sounds like that might fall under my "doability". Should I pull the plastics off the right or left side to access this (please don't say both ) ?

    Right.

    NOT worth your time or money to replace with BMW parts - go aftermarket and all-metal for both fittings.

    I felt the same way as you when I got my RT last year. When you remove the side fairings, be careful with the tabs near the cylinder heads. I learned the hard way: Broken RT Fairing.

    After a few times, pulling the fairings and fuel tank have become a core skill to maintaining an RT. Once you get in down it's only about 15 minutes work ... plus two days to repair the broken tab.
