gas smell

fired up my 03v tonight for the first time in three months and had a strong gas odor. I ran it only a minute or so and turned off. pulled the plastic engine guard off and could see a stain there but no puddling, checked but couldn't find any leaks. started the bike up again ran for 5 minutes then let it set for about an hour. no gas leak and no odor. could there be gas odor without having a leak after sitting so long? the stain in the engine guard could have been coolant I suppose.

Often, not running for a long time will cause the short hose between the injectors to dry out and shrink, allowing a leak when first starting up. After it gets wet, it will swell and seal.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

Next time you have reason to remove the tank and airbox, I'd go ahead and put some better clamps on that fuel hose. Get the screw down type that are specifically for fuel line.

Here's where that hose is:

Exactly. My '07 does this since it sits a lot; my wife rides it way less than she should. It's a bit unnerving at first but the leak and odor go away quickly once the bike is started and ridden.

"How rare that we can point ourselves inevitably west and go, go, go. Run out the highway and the hills. Slide our fingertips over the creases and the valleys of the impossibility that is America. You canít grasp its vastness from a plane. Itís diversity from a map. You have to put your feet on the ground. Your hands in the dirt." - Zach Bowman

It will get worse. Mine started to do this intermittently and I put 100,000 miles on it in 6 years. You need to replace the hose (in GWs picture) with a new one and get fuel injection hose clamps. Pretty soon it will leak all the time. It is not a hard repair.

Just replace the little hose using fuel injection rated stuff, good fuel injection clamps are key. I'm amazed the sucker is holding fuel at all if its original.

US ethanol blended fuel kills fuel system components. I check my bikes before any big trip, found 2 year old hoses cracked and leaking. Buy the good high pressure rated fuel line for fuel injection systems.

While your in there, replace the old vacuum lines too, replace the crappy coolant hose clamps, good time far a valve check etc. Preventive maintenance keeps you trouble free!
