Mystery Fuel Leak
I just returned from a 4K mile summer trip. For the first time in 5 years and 70K miles my LT exhibited a problem. On several mornings during initial fire up my 2002 LT leaked fuel on the ground? I peeled the plastic on the clutch side and could find no reason??? The fuel leaks over the front timing chain cover and valve cover creating a 6 inch diameter spot on the ground. The leak stops after about 30 seconds? What's really weird is that it does it in hot and cold weather conditions and not every time I start it in the morning. Once the bike been running during the day it never reoccurs.
I suspect that the cold start enrichment fuel circuit must have a loose connection, cut in a hose or bad O-ring? But for the life of me I don't understand why it doesn't repeat at every start up. This problem occurred on my second day out of a 14 day trip. After not being able to locate the problem on the road, I simply rode it and noted the time it occurred. The bike runs beautifully as usual at all other times.
I plan to tear all the plastic off now that I'm home and try a cold start up test when I can see the fuel lines.
Any collective wisdom on this subject? Intermittent electrical problems I'm more than familiar with, but an intermittent fuel leak is just seems weird.
Anyone experienced this? Let me know, maybe you can save me some time and point me in the right direction.
It's a good thing I'm not a smoker, as lighting up a morning cigarette when starting the bike could have been fatal!!!
