hi all, i yust had a new gas tank installed in my '95 s2 last weekend; i was told that the leaking i was getting when the petcock was in the "on" position should now stop. no such luck - any idea what's causing the leak? thanks, doug s. (last saturday, it was beautiful riding weather; today, there's 2' of snow, and it shows no signs of stopping.) | ||

Without being able to see your bike I would say the float needle in the carb is letting fuel leak by and your carb overflow hose is where the leak is coming from. A simple cleaning of the carb should cure the problem if this is it. | ||

The only recall related to an S2 tank took place in 1994 and was unrelated to the petcock. | ||

Doug, did they swap the petcock from your old tank to the new one??? I want to say there is a small O ring in that area you may want to check (my memory fails). I had this problem before and I cannot remember what I used but it was a sealant of some type. Make sure that is were it is coming from because like Edv said it could be a dirty carb or just need new gaskets. Some times that float bowl drain screw can cause a pretty good gas leak as well when the petcock is in the "on" position. I will check a spare tank tomorrow to see what the deal is with the petcock. I do remember I had to really tighten that sucker..... If I forget shoot me a pm... Frank | ||

the new tank came w/a new petcock - the whole thing was replaced all at once. (curious how a '95 could have a recall in '94. and all i know is the dealer said there was a recall on it and replaced it for me at no charge last week.) there is no leaking at all, w/the petcock in the off position - same as before the new tank & petcock was installed. the bike started leaking about a year ago... re: dirty carb/float/needle/screw/breather suggestions - keeping the petcock in the "off" position stops all these types of leaks? i'd think i'd still get a little leakage, what's in the carb anyways. maybe i am, but i am not noticing it? thanks all, for suggestions. doug s. | ||

Get the recall number from you dealer. I think he is in error. We'll find out with facts. The 1995 S2, just like the 2010 car I drive, was produced starting in 1994. The only fuel tank reacall I am aware of was in 1994. Eager to learn what the dealer is talking about. | ||

Doug - did we do it? I've been out for a bit due to surgery...but if you post some info from your receipt it could help us figure out what was done. My best description of the petcock-open leak is this: There is a needle and seat in the carb, connected to the float. When the float is up (bowl full), it pushes the needle into the seat, closing the 'entrance' for fuel. Float drops, fuel is allowed in from the tank. Think toilet tank, if you will. If it's leaking from the carb, you could have an issue with the needle/seat, keeping it from closing. Could be debris stuck in there, or a bent needle, or a gouge in the seat, or a mis-adjusted float. My guess, since it "started" on its own, is you have some debris in there. Having the petcock shut off keeps the weight/volume of the tank itself off of the float needle, so no "more" gas is pushing its way into the bowl and overfilling it (all that will go in, is what's already in the hose). If the valve is open...well, you have 5 gallons pushing against that needle and seat, and it will eventually overfill the bowl and leak. | ||

I could be as simple as a bad or damaged fuel hose.... | ||

If the carb has never been rebuilt you are a few years past due. That rubber does not last forever. If you need any help with anything Doug do not hesitate to post. Frank | ||

ya, joe, your dealer did the work. (sorry to hear about your problems; i hope you are doing fine!) from the receipt: sc#802: rcl 95 buell s2 fuel cell asmb - (6/9/1995) - bulletin b-005 10014 - clamp, hose p0110.8q - fuel tank assy it sounds like i have a carb float/needle issue; i should pull it apart and see what i can find. could be debris or deteriorated rubber; the carb has not ever been rebuilt, tho i rejetted it some time around 2001, when i installed the race hedder/muffler. thanks all, doug s. ps - frank - here's my vin: 4mzrt11h2s3000569 | ||

Thanks Doug. Here is the recall: http://www.badweatherbikers.com/buell/messages/384 2/B005-263552.pdf | ||

Looking up the recall sheet on H-Dnet, it specifies that the petcock stay with the fuel cell, and a new one be installed with the new fuel cell. So....if you were having a petcock issue, it would have been fixed or at least changed with this recall. Still guessin' it's a float needle... | ||

A way to check the petcock and also clean the float bowl is to drain it using the drain screw in the rear of the float bowl. Locate the over flow/drain hose usually running behind the rear cylinder pushrod covers and down around the trany sprocket put something to catch the gas where it ends (note alot of times it comes out on top of the shock) Using a long straight slot screwdriver lossen the drain screw with the petcock off it will drain the float bowl....You can flush the float bowl by just turning the petcock on... |
