2005 KLR approaching 30,000 miles. I noticed the engine speed was not dropping below about 1800 rpms at idle on my last ride. When I arrived at my destination and parked the bike I noticed a lot of fuel dripping from the bottom of the bike. The fuel flow stopped when I shut off the fuel valve, and at first glance there is no sign of leaking fuel lines. I trailered the bike home, and unfourtionatly we just got dumped on with snow, so I have not been able to take the bike apart yet.
Any ideas?
I had a similar problem years ago with a 1963 Ford Falcon, where a diaphragm cracked in the fuel pump, and it pumped the fuel out the side of the fuel pump, all over the engine block. Fourtionatly the hot exhaust manifold was on the other side.
Hopefully things will thaw a bit tomorrow and I can get out and take the bike apart to find the problem.

rapid fuel loss
Howdy,
I get fuel leaking from the carb from an over-delivery to the carb-bowl from the tank. This seems to be due to a malfunctioning of the valve that controls the supply of fuel to the carb. It may be sticking open due to junk (dirt, bug legs, chunks of "varnish") and can be addressed by cleaning or sometimes just by draining the carb bowl. I have also noticed that this seems to happen in hot conditions and wonder if it is not caused by the fuel in the hose to the carb boiling and as it expands being forced into the carb. I wonder if anyone has tried some kind of heat shielding, even just sticking reflective tape on the fuel hose itself. This flooding of the carb with gas and the leakage of such gas has been associated with the engine refusing to idle and repeatedly stalling. Are you noticing this? A short term fix, for me, has just been to shut the petcock valve "off" for a minute to allow the valve to re-seat, maybe?
In another vein, that was a great article on an analysis of causes of motorcycle accidents. Very informative.

looking for former owner of 2004 wrecked klr near sacramento, cak
I'm considering buying a motor from a dismantler near Sacramento CA who has a wrecked 2004 KLR. Does anyone know who might have owned this bike? According to him, the motor is in good shape and he started it up before parting out the bike. However, I would like to see if I can get any other info. I also want to know if the previous owner did the Doo replacement.
The wrecker doesn't know who owned it (probably got it from the insurance company)
