I have 2007 Wee with 40k miles. Last week when warming it up for ride to work, smelled fuel, looked down, and it was dripping on skid plate from throttle body area. Shut it off, drip quit, road wife's bike to work. In the evening, lifted tank but kept connected, started up, no leak. I'm thinking that maybe tank was building pressure and not venting correctly or something. Assemble, go to warm up next morning, fuel leak again. I mean, it leaks probably about 1/8 cup while I am shining flashlight all around trying to find, no go. So, my mornings are in the 60's, evenings above 80. I disassembled again, removed aircleaner, look for fuel/dust trail, wet area, split hose, nothing obvious at all. I just ordered new injector seals & o-rings, plastic t-fitting, and 2 of the hose caps that are on the throttle bodies. Anybody have any ideas or similar problem? I did a forum search, found nothing at all.

Thanks
Dale

My 7K 650 dribbles, too!

I too, have the intermittant leaky fuel problem on my 07 650. Not surprisingly, I can't locate the source. Plastic, fuel tank, and air box are off now.

Following the advice here, I intend to replace the short fuel line and clamps. In addition I plan to replace the O-rings at the throttle bodies.

Might somebody here have the O-ring part number? Better yet, might somebody have the dimensional details for those O-rings?

Thanks to all for the gobs of information on this board!!!

Chances are new clamps will fix it. A new hose isn't a bad idea. The rest is almost certainly overkill. I know of only one report of an O-ring problem and it was not intermittent.

Thanks, Greywolf.

I was thinking along the lines of - Since I'm in there, I might as well do those, too.

Would be a real pisser to put it all back together and...

GW has your solution. Mine did it too. I bought 2 high pressure clamps and a 2 inch section of fuel injection rated hose.

Done. Fixed.

You can look up under the tank when its running and see the leak. It quits real quick so find the hose, start it, then look at the hose.

Yep, planning on doing that.

My Strom' is easily the best cycle I've owned. Done things to it, and taken places that would make the dirt boys smile. So it only seems right it should exact a little revenge on me...

Again, thanks to all (esp. GW) who take the time to help fellow Stromers!

Soooo - I installed a new hose, new clamps, new o-rings and injector seals.

Fired it up - bone dry. Leaks are history! Thanks again.
