Title: Fuel in air box? Post by TheProduct2007 on 07/23/13 at 13:37:41 I recently bought a 1996 suzuki savage as my first bike. I was told it was sitting for a year before they started riding it a month ago. I took it home and tried to start it but the battery seemed weak so I tried jump starting it. During certain times I would pull on the throttle to see if might help and it would fire but never start. After a few tries we noticed gas coming from the exhaust so we stopped and let it dry out while we checked other areas. The air box was filled with gas so we emptied out the air box and noticed it was still filling up two more times before I turned the fuel valve all the way to the left. I believe the issue may be that some old gas got the valve or float bowl stuck. How do I fix it? Is there a way to fix it without taking off the carb? |

Title: Re: Fuel in air box? Post by WD on 07/23/13 at 13:43:18 Try tapping the fuel bowl with a screwdriver handle. |

Title: Re: Fuel in air box? Post by justin_o_guy2 on 07/23/13 at 13:44:39 Float MAY be stuck, check oil,, if over full,, may be loaded w/ gas. If I Ever dont want mine to start, all I have to do is twist the gas,, it wont,, First, make absolutely Certain the battery is Hot & healthy, |

Title: Re: Fuel in air box? Post by Dave on 07/23/13 at 13:49:14 It sounds like the vacuum diaphragm on the fuel petcock may be leaking. Do this check.....all of it.......don't skip anything. http://suzukisavage.com/cgi-bin/YaBB.pl?num=1251932429 |

Title: Re: Fuel in air box? Post by TheProduct2007 on 07/25/13 at 22:11:04 I got the bike started. I thought it was the carb at first but it was a much easier fix then that. It was the spark plug. Since it was cranked three days prior I didn't think it could have been that. I dried out the airbox and got a new battery. I put the battery on earlier today and tried to start it and after trying a few times I noticed that fuel was still spilling out of the exhaust again and filing up in the air box. So I took a look at the spark plug just to see and there was carbon residue build up on it. Replaced the spark plug and it works fine. I would like a few recommendations on fuel treatment and something I can put into the fuel that can help keep the engine smooth running and clean. |

Title: Re: Fuel in air box? Post by TheProduct2007 on 07/27/13 at 15:41:29 Ok so there was a fuel leak still but it was because the float bowl was stuck from excessive buildup. We cleaned that out and now the bike chooses when it wants to run. We primed it up then set it up to run the tank and it cranked great a few idling hick ups at first but when it idols now it's fine. The issue I'm running into is the initial start. I will start if the engine has been cool for a while then put in either half choke or full and you have to apply a little throttle but if the engine cuts off after it started you have to wait until it cranks up again. It will turn over but it just doesn't want to fire after it starts and then chokes out |

Title: Re: Fuel in air box? Post by Serowbot on 07/27/13 at 17:09:57 3 people have already told you what to do... and you haven't done it... It's time ... Test your Petcock,.. don't just turn it to Prime.. (http://suzukisavage.com/cgi-bin/YaBB.pl?num=1251932429/1) Do this test,.. do all of the test.. not just one part... |
|
Title: Re: Fuel in air box? Post by TheProduct2007 on 07/28/13 at 08:53:37 But the petcock was not caused the other issues, are you sure it would be the reason why the engine will only fire if its cooled? |

Title: Re: Fuel in air box? Post by Serowbot on 07/28/13 at 09:17:56 Nobody here, will be sure of anything until you do this test... It will take you less than 10 minutes... Then, we all know... Professional mechanics have spent many hours and $100's of dollars doing unnecessary repairs and carb work, before finding the bad petcock... We don't do that here... Fuel problem?... Check the pet...First thing... You came for advice?... Take our advice... If it ain't the pet, we can continue... but, we have to know... |

Title: Re: Fuel in air box? Post by TheProduct2007 on 07/28/13 at 09:32:28 Ok I will check it |

Title: Re: Fuel in air box? Post by Steve H on 07/28/13 at 09:34:44 Think flooding. If it's sucking fuel through the diaphram into the intake, after it sits, the fuel evaporates. When you restart, you have a nice rich mixture to start but it's too rich once you get vacuum up because of the leak. It floods the engine out. You wait a few and the fuel evaporates, bike starts...cycle repeats. It only takes a couple minutes to check it and you'll have eliminated a BIG source of fuel related problems. Do the check...all of it. Mine started occasionally getting slobbering rich when I stopped and flooded out one time when I stopped. I did the check first based on advice here. Found I had an intermittent leak in the diaphram. It was very small but it was enough to cause problems sometimes. These guys know their stuff. They've seen it happen so many times. They know right where to go to find the problem. |

Title: Re: Fuel in air box? Post by justin_o_guy2 on 07/28/13 at 09:50:27 The mechanics "out there" see all kinds of bikes. Only rarely do they get one of these. You are in a group of guys who have loads of experience with these bikes. We have seen at least 2 engines destroyed at Dealerships just getting an oil change. When a suggestion comes from several sources here, man, do yourself & us a favor,, jump on it.. so that problem can either be eliminated or repaired. Thats a real common issue with these. The next thing that bites newbies is a battery hot enuff to spin the motor at a decent speed, but,, even tho it sounds like its spinnin fine, the load on the battery will often pull the battery voltage juuuust low enough the spark wont fire,,&, to make it all the more confusing, you can pull the plug & check spark & THERE it is! BUT, the battery isnt driving the piston against compression,, so, the load is much lower.. so,, if its not starting but its spinning over, check voltage, sitting & while spinning the starter. Need alligator clips for your V-meter or a friend |

Title: Re: Fuel in air box? Post by TheProduct2007 on 07/28/13 at 19:23:01 Ok, I just need to ask a few questions about this test first because I don't understand the prime and cap test. After checking the hose that connects to the rear of the petcock for fuel and sucking on it to see if it is sending fuel, I need to do a prime and cap test (that is if the rear hose isn't sending fuel). Disconnect the line that is connected (in the picture) and block the piping. After I block the piping set the petcock to prime and see if it runs better. Ok if it doesn't change I still have to run it for about two gas tank loads to make sure correct. Please correct me if any information is incorrect. Also, if fuel comes out of the line I disconnect that I am suppose to block, does that mean the petcock is bad also or is it normal. |

Title: Re: Fuel in air box? Post by justin_o_guy2 on 07/28/13 at 22:32:05 if fuel comes out of the line I disconnect that I am suppose to block, does that mean the petcock is bad? Test is over if you suck on that & get gas. It fails. Its not supposed to ever get gas IN that hose. That hose is supposed to draw a diaphragm & open a passage. That hose is supposed to only deliver vacuum to the petcock & not supposed to suck gas. Im not winning,, |

Title: Re: Fuel in air box? Post by Oldfeller on 07/28/13 at 23:47:20 No Justin, you fer sure certainly ain't a winning on this one. ;) All 3 active moderators have told the boy to do the test. He got a PM from me telling him all he needs to know about the why's behind the test. He's done with the explaining part ..... NOW HE NEEDS TO GET HIS HANDS DIRTY AND DO IT. (jest suck on the silly tube, if you get any liquid gas, even a drop it's a fail) Pending him posting back what happened, he's done. Only other possible step would be to find out where he lives so we can try to send him some help him because if he can't do Serowbot's Test he isn't going to be able to do anything else either. ============== Now this here ditty is supposed to be a joke, son I think ... ::) well, mebbe not The Simplified Serowbot's Test Step #1 Do you have a stock vacuum petcock? If "yes" go to Step #2 Step #2 Replace with Yamaha Raptor petcock pt. no. 5LP-24500-01-00 Considering how many stock vac petcocks fail the existing test lately (like all of them) vs the like zero that pass it, perhaps the shortened test format can be substituted for those mechanically challenged people amongst us. This would certainly save time and aggravation all the way around it would. |

Title: Re: Fuel in air box? Post by justin_o_guy2 on 07/29/13 at 00:31:51 Yea, under $30.00 & Remove all question.. pretty simple., |
|
Title: Re: Fuel in air box? Post by TheProduct2007 on 07/29/13 at 18:40:37 I followed the instructions for test and tested the vacuum line on the rear end of the petcock. It didn't like any fuel nor did it show signs of leaking fuel. No deposits or anything. |
|
Title: Re: Fuel in air box? Post by Oldfeller on 07/29/13 at 19:52:11 So now you go to the plug and the tee and you run it prime for a week or so, then you can say if it ran better or not. |
|
Title: Re: Fuel in air box? Post by TheProduct2007 on 07/29/13 at 20:55:46 So block off the line that I checked for fuel and set the petcock to prime and see if it runs better? I will start this tomorrow. Do you think this would help with it not wanting to start when its hot? |
|
Title: Re: Fuel in air box? Post by justin_o_guy2 on 07/29/13 at 21:06:25 Youll soon find out,, |
|
Title: Re: Fuel in air box? Post by TheProduct2007 on 07/30/13 at 08:51:14 So what do you recommend I cap the line and the carb with? |

No, but what you describe IS one of the main symptoms of a failing vac petcock, which is starving your engine for gasoline periodically until your engine just quits. We can't count the number of times a failing vac petcock has stalled someone's bike in traffic and then wouldn't let them crank it back up (trickling gas in soooo slowly the bowl took forever to fill back up) |

You have read the test right? What does it tell you to use? :-? I'm beginning to wonder if you have even read the test ..... much less even tried to do it. (I'm done here .... he's obviously just here for some idle conversation) |

Title: Re: Fuel in air box? Post by TheProduct2007 on 07/30/13 at 09:10:58 You know what I did read it. It said take off the vacuum line from the rear petcock and suck it to see if you pull any gas and no gas came through the line. Then it says to take pull out the line and block it. I asked you what do you recommend blocking it with, not how more of a smart ass you can be. You have been recommended this test from the beginning of the conversation and it wasn't the cause of the first two issues. I no longer need your help because I will take care of it on my own I spent 500 on the bike and got it running and moving without doing a petcock test until the issue with it not wanting to crank after being ran for a while which sounds like the ignition coil is getting too hot or has a bad ground. I understand y'all's reasoning as to why it can be the petcock and I have done the initial test part and I'm starting the prime and cap test but I no longer need any smart ass remarks to help me fix the bike I will do it myself. So moderator please end this conversation and delete my account. |

Title: Re: Fuel in air box? Post by justin_o_guy2 on 07/30/13 at 09:45:15 Pretty uncommon,, owell,, |
