klr naming

[jeepaviation]

I noticed that I had a fuel spill under my KLR this afternoon. It was not running. It was just sitting there on my front driveway in the sun (104 deg outside). After searching the fuel tank thoroughly I found no fuel leaks. I did notice fuel moisture leaking out of the header / engine connection and at the Header / muffler connection beneath the right side of the seat. It seems that the Fuel has leaked out of the Carb, into the exhaust. Any Thoughts?

It would be good to have more information on this one. Exactly where was the gas on the ground found? How big a gas stain was left on the driveway? Where could it have dripped off of? The "moisture" you found on the header pipe...was there enough to drip? Gasoline expands under pressure as it is heated, and some could have pushed past the needle valve but I don't believe it could have passed enough into the engine as to flow through the exhaust valves into the header. When you shut off your KLR, the spark stops immediately, but fuel continues to flow for every revolution of the engine. It usually is not a good thing to routinely shut off a gasoline engine at higher RPM's as the fuel will wash the cylinder walls of any oil film that exists. It sounds as if you did not find a smoking gun still leaking, and there is a simple explanation tot he leak if it is small. Capt. Bob in Durham, CT.

Is your tank vent line hooked up correctly (it's sort of under your crotch, under the front of the seat, and *should* thread down to end near the swingarm). I've parked my bike in hot weather and had a drop or two of fuel come out of there. I think it's from hot fuel vapor from inside the tank running through that line, cooling, condensing, and dripping. I've never seen more than just a few drops. Check to make sure your vent line is connected, and the next time you park keep an eye and see if the bottom of that line is moist.

Group, Fuel was found beneath the rear shock. Not enough moisture to drip from the Header/Engine connection. Although about a cup full had leaked from the Exhaust / split connection beneath the seat. I gained access to the fuel vent lines and found one line pinched at the forward vent canister. (This is a 50 State Bike with all emmisions mods). As soon as I straightned the vent line I heard the familiar gas tank whistle that I normally hear after a hot ride. Obviously the Fuel tank had been under a considerable amount of pressure. I am sure that this was the cause of the fuel leak. I find it difficult to understand how the fuel travelled into my exhaust pipe. Assuredly, the fuel was comming from inside the exhaust pipe. I could not find any leak above the exhaust. And, when I started the bike a generous amount of fuel came out of the exhaust. Thank goodness I did not have a tailpipe fire.

Jeepaviation, If the fuel was forced from the tank due to pressure buildup, and the carb float valve didn't seal properly, fuel could have found its way into the cylinder and subsequently out the exhaust valve. Check your oil for gasoline smell. It may be diluted with gasoline and need to be changed. Mike --- jeepaviation wrote:

I would change the oil. if gas made it through the cylinder into the exhaust, gas would have gotten into the oil too. Craig Kahler --- In DSN_KLR650@yahoogroups.com, "jeepaviation" wrote:

Group, Good point. I had not thought about the oil. I will stop by the Kawi Shop after shift and change the oil tonight. Thanks for the good posts.

Can you imagine that, a KLR with an afterburner? I wonder how much thrust would be gained from that accessory? I suppose the KLR is as advanced as the early '50's Naval Aviation with their electic mix of the Ryan FR-1 Fireball and the North American AJ-2 and AJ-2P Savages. And there were several other designs that never made it out of the test phase of developement. Buddy eckmac leftcoastklrsociety

Group, Well, Two of you hit the nail on the head. I performed the oil and filter change this evening. There was a clear odor of fuel in the oil. Thanks for the tip. 106 Degrees outside today and no fuel leaks. problem resolved.
