Hi,
This darn bike. After a trip the crotch of overalls stink of gas - and when entering the shed its parked in, also gas smell. Have felt gas under engine - but deler cant find leak. Road grit sticks to top of tank in two streaks.
Any ideas how I can find where leak comes from - without using a match?
what fixes this?
Any all help app.

| Maybe the seal on the cap?? It's the only way I've ever gotten gas on my crotch riding. | |

EFI model? The first thing jumps to mind is your overflow hose is pinched or blocked - vapor pressure may be pushing gas out cap seal. Seems I've heard of petcock leaks in previous threads also. Not many thngs will cause gas to migrate back into your lap.
Don't smoke. Please. Your fuel problem will be mild by comparison. | |

| That would be my best guess as well. Had it happen on a 89 Goldwing once. Can't believe the dealer could not find it.  |

Actually, I do believe that the dealer did not find the problem. Some of the horror stories that I hear about the under trained, too young, cant find the left-handed screw-driver Harley-Davidson Maintenance department personnel now-days.  | |

| you could pull the seat and the dash on the bike and see if the hoses are hooked up to the overflow, they may not be connected and if that's the case when the tank is full you may get a little slosh down uner the dash panel and in your lap, if the holes are plugged or the lines are pinched you may get some blow by out around the gas cap. I know mine are ok because I'm forever trying to top the tank off and when it warms up a little the fuel expands and sure enough I get a little puddle underneath the bike...bad for the environment and tha wallet..we pay around four bucks a gallon for the stuff. | |

| Bob, speaking of gas the price of Regular in a few stations around here is running 1.99.9 to 2.09.9 now. What a drop in price from our trip. Remember the almost 5.00 a gallon place. | |

I'm glad gas is cheaper tho... | |

| Bob, I don't remember the clutch issue you had. What happened?
Even with the problems we all had it for sure was a great time.  | |

I can't believe I brain farted this! There is usually a dye in all fuels that identifies it. It is a UV dye and by using a black light in a dark room you could trace the leak. Clean the entire area with something like S100 or something that will not effect the paint. You do need to get the existing dye off or it won't work. Us the UV light to verify it. Then, go for a ride and when you come back, use the UV light to trace the leak.
If, by chance the gas does not have dye, you can get it easily. http://www.shop.com/op/aprod-p208024...ver?sourceid=1
We used to catch the Koreans stealing MoGas using the UV light. | |
