Title: Gas-type liquid coming from Air Cleaner Drain Tube Post by bggjr on 07/12/12 at 14:38:33 So, I just bought a 2000 Savage the other day. It has 9,000 miles. The guy who sold it said he gummed up the carb. Anyway, I drained the tank and carb, filled the carb with carb cleaner and let it set for a while. Drained the carb, then put a little gas in it. The bike started but when it runs the cleaner drain tube expels liquid everywhere. I took out the air cleaner and it is definitely coming from there. Is this some sort of jet issue? Like, a dirty jet or something? Anyone have some ideas? I really wanna ride this bike! haha I've attached a pic. |

Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by splash07 on 07/12/12 at 14:44:00 Sounds like what just happened to me, bad petcock causes fuel to leak either into the airbox or into the crankcase. If its in the airbox just clean everything up, replace petcock with a raptor, and ride. If its also in the crankcase you will need to change the oil. |

Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by Savage_Rob on 07/12/12 at 15:12:38 Fuel is overflowing from the carb to the airbox and is draining out the drain tube. It could be the petcock or the carb itself (if the petcock was left on Prime), though the stock petcock is prone to such failures and the amount shown in your upside-down image makes me think it's the petcock. If the stock petcock is functioning properly and is not on Prime, even a faulty carb could only leak very little fuel. There's a post in the tech section on how to test your petcock. Please try that and, if it proves the petcock is bad, I would agree with the suggestion that you replace it with a Raptor. Personally, I'd change the oil after it's fixed just to be sure it's not contaminated. |

Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by bggjr on 07/12/12 at 16:09:34 Just checked the vacuum line from the petcock and there were trace amounts of fluid in it. I did not suck on it like the one helpful article suggested because I could not make myself do that right before dinner. Should that be 100% dry? |
|
Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by Serowbot on 07/12/12 at 16:31:32 Yes, it should be dry... Try the test in this link...Test your Petcock,.. don't just turn it to Prime.. (http://suzukisavage.com/cgi-bin/YaBB.pl?num=1251932429/1) (capping off the vac line and running on Prime setting)... if that fixes the problem,.. you have a bad petcock.. |

Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by mayor4u on 07/13/12 at 08:48:20 I would make sure your not overfilling the tank.. re: level above the ring at the filler neck, forces fuel to the airbox, I leave about a 1/4 " below the tube when filling my tank |

Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by Oldfeller on 07/13/12 at 11:00:48 That much gasoline in an airbox is dangerous -- it can come from the float valve in the carb not sealing off correctly, it can come from the vac petcock leaking fuel down the vac tube and back down to the air box. But in either case there is a whole LOT of it. One backfire through the carb and you could be sitting on a weenie roast (your weenies). :o ouchie ouchie ouchie Do the seal off tricks for the vac petcock mentioned up thread first, see if it stops the problem. You may be lucky and just have another of many bad vac petcocks. http://suzukisavage.com/cgi-bin/YaBB.pl?num=1251932429/1 :( However, if you poured straight Berryman's into your carb and let it sit, you may have damaged the float valve seat's rubber seal surface (and perhaps quite a few other things made of rubber as well). No carb cleaner should ever be put full strength into a carb and then let sit to eat things. |

If the tank was overfilled and the petcock was working properly then the gas would come out the filler cap as many have seen. If the petcock was not working then it does not matter how much fuel you put in, the fuel is going to leak out somewhere. |

Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by bggjr on 07/13/12 at 13:51:13 Okay. Changed the petcock. Glad I did because the vacuum thing just seemed weird to me. I like it the way my old Honda has it. Anyway, still did not stop the leak. I'll mess with the carb now to see if I screwed up something. I have no idea why the pic posted upside down. The file showed it right side up. |

Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by bggjr on 07/13/12 at 16:40:39 Took the carb off. The spring that connects the needle valve to the floats was at the bottom of the bowl. |
|
Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by Oldfeller on 07/13/12 at 16:52:14 That will sure do 'er .... no connection between needle and float. How did the valve seat and rubber needle tip look? |
|
Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by bggjr on 07/13/12 at 17:35:26 So far so good. Did not have time to tear it all down. The main jet was clogged with only half visibility. The vacuum slide was super slow , then I cleaned the jet and it was much better. |

Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by Serowbot on 07/13/12 at 18:16:59 Wow!... that's a lot of boogers... This thing is going to run great once you sort all this cr@p out... ;D... |

Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by Oldfeller on 07/13/12 at 19:28:43 This is a man who needs an in line fuel filter ..... |
|
Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by bggjr on 07/13/12 at 22:18:05 I did that too. I think the previous owner just bought cheap gas. It's lame because you can get 100% gas here in OK. And, seriously, why would you buy the cheapest stuff when motorcycles get such good gas mileage? |

Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by bggjr on 07/21/12 at 13:20:09 Replaced the float needle and the seat. Put the carb back on. Started up just great. Idled well. Then after a couple minutes, the leak came back. Makes no sense. Could it be that the float needs adjusted? Maybe it's not engaging the needle properly? I tested it before I put the bowl back on and it did not leak through when engaged. |
|
Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by bggjr on 07/21/12 at 17:57:12 Adjusted the float level and it seems to be okay. I just let it idle for about 5 minutes. I'm going to try again when it cools off. It's 103 today in Oklahoma. |

Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by bggjr on 07/21/12 at 19:29:35 Took it for a spin around the block. Started leaking out the air cleaner drain again. Ugh..... Any ideas? I know this has to be something super tiny. Like millimeter tiny. What are compatible carbs? haha |
|
Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by bggjr on 07/21/12 at 19:33:12 Also - I barely have any gas in the tank as I am trying to fix this problem. Like, less than a quart. That shouldn't make a difference, right? |
|
Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by Oldfeller on 07/22/12 at 05:06:22 Yes, if you don't have ample gas supply you multiply your symptoms with the "running out of gas" symptoms. PUT SOME GAS IN YOUR GAS TANK So far you have put on a fuel filter, put on Raptor petcock, cleaned the carb, replaced the needle seat. Next, go to the bottom of the carb float bowl to the drain nipple and its controlling screw. Put a piece of clear tubing on it and run the clear tubing up beside the carb body (use some tape to hold it steady in place) and do not cap it off. Unscrew the controlling screw by the bowl nipple some and fuel should rise up in the clear tube to match exactly the fuel level that is inside the bowl. Now you have a readily visible means of checking your fuel level in your float bowl. If it rises above the bowl joint, you have a float needle seating issue. When the bowl is first put back on empty, turn the petcock on and the fuel in the clear tube will quickly rise to the correct needle seating point. Mark this on your carb. Then, if you have a slow leak, it will slowly rise more until it gets way up over the bowl/body junction. The leak starts running gas to the airbox when it gets venturi high .... |

Do ya know what that spring/wire is for ? Didja know it will run perfectly fine w/o it ??..........or laying in the bottom of the bowl. Well, hell, I had to add something........as I am at a loss as to what is causing this leaking problem.. |
|
Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by Oldfeller on 07/22/12 at 08:46:22 The spring wire is intended to provide the positive RETRACTION of the needle away from the seat to make sure the fuel valve opens correctly each and every time when the float goes towards the "down" side of its life. Will it work without it? Yes, until the first time the needle sticks in the seat and doesn't follow the float tab on down ..... :) Actually, the words we get back from the poster about what they actually did reflect their understanding of what's going on and what our words meant to them. Lots of times I suspect they don't even read all the way through the links we provide and they either do not do the tests correctly or misunderstand what we are suggesting that they do. When one gets stuck, I go back up and read the entire thread and note the places there was not response to a suggested step or test -- to your point it isn't logical that he has done all that he has done and still has the problem. |

Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by bggjr on 07/22/12 at 19:39:19 I'll get to the needle sometime this week but do that clear hose test first. I do appreciate the folks who chime in. I wish I had the time to act on the advice immediately. This stuff has been super great. |

Title: Re: Gas-type liquid coming from Air Cleaner Drain Post by bggjr on 08/04/12 at 21:00:38 Okay. Cleaned the needle. Filled the tank with 100% pure gas. *Controversial move* Put 1oz of Seafoam in the gas. Started up well and I let it run for a really long time on idle. It did not die. After a while, I gave it some throttle. No leak. AWESOME. Took it for a spin. Died. Pushed back to the garage. Poked around and noticed the previous owner had jacked the idle settings and basically set it where gas was just pouring in (this is the idle screw that you have to remove the cap to adjust). Made some adjustments thanks to handy threads on this site. Long story short, I am going easy and only riding it a couple miles at a time just to make sure any "gunk" is gone. I've gotten it up to 50mph with ease. Acceleration is fantastic. The bike doesn't die at all. It does occasionally make a pop when I turn it off. I think that means it is a bit lean, right? Also, the bike has a Jardine exhaust and it looked like the carb was totally stock in terms of jets. Not really wanting to change them. Thanks for such an amazing site. The info here is incredible. |
