Title: Gas puddling below bike Post by nodnarbing on 01/30/12 at 06:24:04 Haven't driven my 98 in 3-4 days, went outside to crank it up last night. Pulled the choke out, fired up...so I walked away and let it run. Came back to push choke back in and let it idle and there was a puddle of gas below the bike. Shut it down, inspected where it was coming from....couldn't really pin point the problem but it's somewhere in the area of the meeting of carb/air filter. Took everything I could off, check the airbox, no gas in there. Started bike back up with things off, no gas leak. Went to start it for work this morning (daily driver, btw) puddle of gas again. Didn't move the choke this time. Started looking on here saw someone mention tapping the carb and moving the petcock. Did both and no gas leak again. Rode into work, and could definitely tell a difference in the way it was riding, A LOT more backfiring than normal. Any one have an idea? I thought about just rush ordering a new carb, as I work a ton, and have no other transportation. |

Title: Re: Gas puddling below bike Post by arteacher on 01/30/12 at 06:29:18 Any gas in your oil? Does it only leak when running at idle? |

Title: Re: Gas puddling below bike Post by nodnarbing on 01/30/12 at 06:35:51 Not that I saw off hand, will check more in a few mins once I'm settled at work |

Title: Re: Gas puddling below bike Post by verslagen1 on 01/30/12 at 06:43:18 Can't say exactly what the problem is... but your leak start after start up... so not petcock I'd say you're in need of either a new float valve or your float needs adjusting. Or may just need a good cleaning. carbs are way too expensive just to replace at least IMHO. a $20 or $30 carb kit and a can of carb cleaner is all you need. and check you vac line for gas. |
|
Title: Re: Gas puddling below bike Post by nodnarbing on 01/30/12 at 06:50:51 I didn't see any gas when I just went and checked by opening the oil fill. I'm hoping that I can get away with just the carb kit and the cleaner. Problem for me is, it has a harley pipe, and a K&N airfilter, so I have no idea what size jets were used or anything. I can fix most anything, when it's fuel injected...never worked on a carb. Where is the best place to find a carb kit? And do I need to worry about what size the jets are for that? |

Title: Re: Gas puddling below bike Post by bill67 on 01/30/12 at 07:35:50 Run some Sea Foam in your gasoline it will clean and lube your carb. |

Title: Re: Gas puddling below bike Post by Serowbot on 01/30/12 at 07:56:14 Do the easiest test first... Check the vacuum line going from the back of the petcock to the right side of the carb for the presence of fuel.. (should be absolutely none in that line)... If you find gas in there,.. read this thread... http://suzukisavage.com/cgi-bin/YaBB.pl?num=1251932429/1 If there is no fuel in that line,... it's definitely your carb float system... NOTE... even when the fuel leak happens only when the engine is running,... it can be the petcock... small tears in the diaphragm don't leak until vacuum is applied... then they gush.... |

Title: Re: Gas puddling below bike Post by thumperclone on 01/30/12 at 08:20:18 both vent tubes attached up the backbone of the frame with no cracks or holes? |
|
Title: Re: Gas puddling below bike Post by nodnarbing on 01/30/12 at 08:25:55 Yes, from what I can tell it all looks pretty intact. Was just talking to a buddy and he said the choke may have pulled out too far and caused excess gas to flow through. May just have to take it to a mech in the morning to see at this point. But I will be trying the petcock and pulling it down to see exactly where it's leaking from |

Title: Re: Gas puddling below bike Post by spacepirates on 01/30/12 at 09:51:11 my guess is a float level issue. depending on how in a rush you are to fix this, you can try the easiest method first, which (and i hate to admit this) would be running through the carb with some cleaner like seafoam. i had a similar issue with one of my other bikes that resulted in my girlfriend's leg being doused in gasoline at 50mph (and she hasn't been back on since :( ) and it turned out the floats had sprung a leak. carb kits... i'm not sure where to pick them up or what comes in them. gaskets maybe? maybe a float valve? anywho, if you can spare the time, i wouldn't buy one until you know you need one (e.g. you've discovered beyond a reasonable doubt the source of your problem). if you have more time, you could rig up a float level checker (clear plastic tubing tied up to the bowl drain) and see what levels are while the bike is running (hint: they shouldn't be higher than the bowl is itself). i've never heard of a choke lever causing gas to run backwards, but who knows, i'm not the most experienced one here. all i can say is that the choke has never been suspect on these forums before. petcock, floats, and clogged carb orifices have been. shoot us some pictures and maybe we can help out a bit more. |

Title: Re: Gas puddling below bike Post by nodnarbing on 01/30/12 at 09:56:18 I will do just that after I get home from work. I see a long night in my future, but at least I will know what the issue is (hopefully). Thanks everyone for their help and info, I promise to repay it somehow. except with carb questions.... ;D |
|
Title: Re: Gas puddling below bike Post by spacepirates on 01/30/12 at 10:12:09 no worries. I forgot to mention that a carb rebuild kit shouldn't include jets (i don't think) and you can just re-use your old ones provided they aren't damaged or clogged beyond repair, so knowing your current jetting isn't a big deal. |

Title: Re: Gas puddling below bike Post by nodnarbing on 01/30/12 at 11:01:45 oh awesome, thanks vers!!! |
|
Title: Re: Gas puddling below bike Post by Savage_Rob on 01/30/12 at 20:08:59 As suggested, I'd check the vacuum line first. |
|
Title: Re: Gas puddling below bike Post by nodnarbing on 01/31/12 at 06:06:55 seems to be the culprit as of now, weird thing is that it doesn't leak when on the reserve position...so that's where it's staying until my new one comes in. still going to rebuild carb with a friend so I can finally learn those things. also, thanks Bill, sea foam worked great, def. could tell a difference as soon as I put it in there. |

Yeah, I hate relying on the vacuum and hoping for no problems that spill raw fuel into the cylinder. Simple install, easy/reliable operation - and it doesn't scrape the frame every time you remove the tank. |

Title: Re: Gas puddling below bike Post by nodnarbing on 01/31/12 at 06:32:26 ah, very cool stuff, this will be ordered shortly...thanks guys |

Title: Re: Gas puddling below bike Post by nodnarbing on 01/31/12 at 08:21:39 haha yea, I was looking at that and wondering until I read a bit further down.. |

Title: Re: Gas puddling below bike Post by nodnarbing on 01/31/12 at 19:42:22 ordered: raptor petcock, a carb rebuild kit, new oil filter and iridium spark plug. now I'm sitting at the front door waiting like a kid ;) |

Title: Re: Gas puddling below bike Post by nodnarbing on 02/06/12 at 09:38:01 all parts are in, but darn the luck if it isn't my late shift tonight. stuck at my desk until 9...oh well, working on it tomorrow after work. do we need pics of spark plug change, oil change or petcock replacement? |

I'm not sure I ever saw a raptor petcock replacement picture. Either way, if you're willing, not a bad idea to document them anyways. you might capture another "simple" step or angle that makes it easier to understand to a newbie. |

Title: Re: Gas puddling below bike Post by nodnarbing on 02/07/12 at 18:54:12 so here's my fun night: Changed out petcock, easy quick, awesome. Go to change out spark plug while I'm at it, since the tank is dry. Take everything off, and it seems to me that my spark plug cap isn't made to take the newer Iridium style....so uh, what can I do? Searched the forum to no avail... |
|
Title: Re: Gas puddling below bike Post by Savage_Rob on 02/07/12 at 19:35:00 I don't know what you mean by newer style, so maybe you got a different iridium plug than I did. Mine was just fine (i.e. not a different form factor). I am using the NGK DPR8EIX-9. It looks basically like this. http://www.ngksparkplugs.com/images/profile/NGK7803-1.jpg |

I think you might have been tripped up by what got me when I got new plugs. you see, some plugs have added on little caps to the plug cap end. the end of the plug that sticks out to the air (as in, doesn't fire in the bike) should be threaded. if it isn't, there is an adapter cap thingy on there that you have to pull off. see plug here with the thingy on it: http://upload.wikimedia.org/wikipedia/commons/6/6a/Sparkplug.jpg see plug here with out the thingy on it (threaded end): http://upload.wikimedia.org/wikipedia/commons/thumb/b/b6/Sparkplug3.jpg/170px-Sparkplug3.jpg different plugs, but you get the idea. it is just some stupid cap thing to make you go: DOH! |

Title: Re: Gas puddling below bike Post by nodnarbing on 02/07/12 at 19:49:41 Ngk..and I don't get it either. Old spark plug has a skinny metal stud on the cap end, iridium one has a much thicker cap end. Won't fit into the cap |
|
Title: Re: Gas puddling below bike Post by spacepirates on 02/07/12 at 19:52:31 maybe you missed my post, but re-read and take some pliers to those ends to see if you can't twist off the adapter thingies. ... i really hope i'm right and don't cause you to maul up your plugs, but it has been this way with my last eight plugs on three different bikes. |

Title: Re: Gas puddling below bike Post by nodnarbing on 02/07/12 at 19:59:36 Trying that now |

|
Title: Re: Gas puddling below bike Post by Savage_Rob on 02/07/12 at 20:19:03 Doh! The wife knows! Okay, so it'll take a while to wear off. How's the bike now? |
|
Title: Re: Gas puddling below bike Post by nodnarbing on 02/07/12 at 20:24:10 Ah, it's 11;45 here, Will install tomorrow after work and update. I had her taking pics for me, so yea..she knows. Then again she's owned a VR-4 and a Miata with an LS1 in it. She knows her stuff. |
|
Title: Re: Gas puddling below bike Post by Savage_Rob on 02/07/12 at 20:35:44 That's actually pretty cool. My wife would probably be hard pressed to pick out which was a spark plug from a half dozen various parts, so it's not something we can share. Good for y'all! |

Title: Re: Gas puddling below bike Post by spacepirates on 02/08/12 at 05:11:04 i'd bet you'd be hard pressed to find any of us on this forum (or any mechanic anywhere in the world) who didn't have one of these moments. |

Title: Re: Gas puddling below bike Post by nodnarbing on 02/09/12 at 08:29:07 Yes, and it cleaned up the weird "stuttering" at about 50-55...new plug helped a ton too. This weekend will be rebuilding carb and oil change time. |
