is doohickey a problem with klr250

[homemadesin@earthlink.net]

A19, 1400 or so on the clock. The "overflow vent" on my gas tank seems to be fond of leaving a puddle of gas under the bike. It really did a number this morning after I filled the tank up, but I think I put to much in. However, it did it as well yesterday (not quite as much) and I had 150 miles on that tank, so it was nowhere near full. It was sitting in the sun and the temp was at most 85F or so here in Colorado. It has done it other times, and it seems to me that the gasket around the gas cap isn't sealing that well. I can understand venting the tank, but why leave a puddle? Is this normal? Z

At electric distribution we always made sure all the trucks were full when we put them in the truck bay for the night.

If the day was in the high 90's or 100's when we filled up and then we pulled into the hot truck bay closing the door for the night. Well see the gas coming up from the below grade tanks was at about 54F and when the temp of the gas in the tank equalized with the hot truck bay some of the gas wasn't in the tank anymore. I'm surprised we didn't blow up the whole building when the first person turned on the lights in the bay. You see this wasn't a problem when all but two were parked outside but when we moved to are new building and could put them all inside, boy howdy. So the new policy stated that the trucks tanks should be filled but left with enough expansion room so that they wouldn't overflow either day or night. Good night boys and girls.

Ok, thanks for the story. Like I said, I can see why when I filled it up too much. How about yesterday, when I was about 3 gallons shy of a full tank? I can understand the gas expanding, the vapor pressures and such, but ....would there be enough vapor passing by and re-condensing as it exits...I just wouldn't have thought it to be as much (between 4 and 6 inch spot on the ground.

Yah, not to many people let me tell stories after the first one. Do you have a California spec bike? If you have a spot on the floor you have a leak some place, just a little condensate wouldn't leave a spot you could still see after awhile. The vent in the 48 states model is up at the gas cap so pressure couldn't force fluid gas out the overflow if the level is down a couple gallons. But a California model with all the tubes and carbon canisters--- all bets are off. Have you tried leaving the gas cap open and seeing if there is still the spot on the area under the bike?

No, it's not a CA-spec bike. I will trace the culprit tube this weekend, but I'm sure is is the one that comes out the back of the tank, just under the front of the seat. I assume the metal spigot (at that point) is routed internally up to the gas cap, just outside the gasket? If I follow you logic, then there is a chance that internally routed tube may have a weep hole? I haven't seen this phenomena while it's been parked in the garage...just while at work (outside, direct sunlight, warm weather). As much as I'm in the garage and around the bike, I'd know pretty quickly. Hmmmm, should I get the tank pressure-checked? Z Yah, not to many people let me tell stories after the first one.

Instead of a leak down test you could just do a "is my tire leaking test". Take the tank off put a rubber stopper in the fill spout and apply just a little pressure,with a hand pump through the tube that you put through the stopper. Stick the tank in some water and see if anything bubbles. You're not directly pressurizing the vent tube so if a stream of bubbles come out your in trouble. Or just take the tank off leave the cap closed, don't have it full of gas sit it in the sun and see what happens. If gas comes out the vent tube down by the back mount you have an internal leak to the vent tube. Alan Henderson A13 Iowa

The KLR250 doesn't have an adjuster lever for the balancer system. Interesting, though, looking at the parts diagram on www.buykawasaki.com, it shows some of the multi-part balancer sprokets that the early KLR650, and KL600 had. Those have been known to either break, or shed parts and/or little pieces of metal.... The KLR650 can be upgraded to the later sprockets. All the best, Mike Eagle Mfg & Eng San Diego, Ca
