Title: Sputter POP and then nothing... Post by ratdog472 on 07/30/06 at 18:15:04 I was riding home this morning and I decided to take a little longer route just to let the bike warm up a bit and got about halfway home and the bike started backfiring, popping and chugging and then when I pulled in the clutch to make a turn it died.. I let the clutch out to make the turn and it almost went out from under me. there was a car next to me so I couldn't hear it running when I made the turn. I check the pettfuelvalvethingy (yes I know what it is called ;) ) and it appeared to be in the right position. After that it would not start. I ended up pushing it half way home. On the way there I figure that I would try a roll start as prescribed in the manual in 2nd gear. It popped over and ran all the way home. Later this afternoon I went out to see if it would start and it did and ran for a few minutes at an idle then the idle got slower and slower but it would still rev. Eventually the idle got so slow that it stalled and would not restart. I haven't tried it since. Any ideas? |

Title: Re: Sputter POP and then nothing... Post by necropsy on 07/30/06 at 19:02:36 First thought was low fuel. Those certainly sound like the symptoms. Cure - switch to reserve. Second thought was wondering if maybe you were driving with the choke out? Cure - don't ride with the choke out. Warm the bike up with the choke, then shut it off and ride. Third thought was wondering if the float/valve was sticking. Knocking on the side of the carb may loosen it up. Cure - clean or replace float valve. |

Title: Re: Sputter POP and then nothing... Post by ratdog472 on 07/31/06 at 05:25:34 Tank is half full of fuel and the choke was not on. I haven't tried tapping the side of the carb yet. I hadn't ridden the bike in about 2 weeks due to vacation and I come back to it doing this. Might be a little gunk in there I guess. |

Title: Re: Sputter POP and then nothing... Post by enophile on 07/31/06 at 07:04:29 Mine was acting similar to yours and it turned out being sediment in the carb that was clogging the jets. After cleaning the carb I had to clean the spark plug because it got fouled from the poor running. |

Title: Re: Sputter POP and then nothing... Post by MacAttack on 07/31/06 at 08:36:31 Along the lines of getting rid of sediment, it's not a bad idea to drain a bit of fuel from the float bowl every month or so. It's amazing what builds up in there. :) |

I'd forgotten that you can also get them at most hardware store stores in the lawn mower section. I like the clear type because younot only get to see when they get crap in them, you can see if there's actually fuel flowing. |

Title: Re: Sputter POP and then nothing... Post by Dynobob on 07/31/06 at 19:36:39 Drain the carb float bowl and add a couple ounces of Sea Foam carb cleaner to a full tank of gas. Is your battery in good shape? Maybe cleaning the terminals would help. |

Title: Re: Sputter POP and then nothing... Post by Brendan on 07/31/06 at 21:39:33 Checking the fuel supply is a great place to start because its easy and cheap to sort out.... But what you have described to us there sounds to me like a sterotypical electrical problem. It could be something as simple as a shot spark plug, or it could be a prob with the HT coil (the one the plug lead is attached to) or the Ignition coils inside your motor. You can check your spark by pulling the plug out, connecting it to the HT lead and grounding it on the motor somewhere. Then turn over the motor. The spark should be "fat", very bright, and regular. If it appears thin, dull and or is only occuring intermittently then thats your problem. Replace the plug, try again. If its still crap then its one of those two coils which is the problem. The cheapest way of finding out which one it is is by substituting them one at a time with one off a mates bike that you know 100% runs well. Note do this test at night, or in very low light. |

Title: Re: Sputter POP and then nothing... Post by ratdog472 on 08/04/06 at 17:10:09 Well I think I am going to start with the fuel system first.. WIth the backfires I was getting when it did it I am thinking it is fuel related.. I have never has a carb off a bike before so this will be a new experience.. Guess a Clymer manual is the next purchase. Is there a float bowl drain? |

Yes, on bottom of the float bowl. |

Title: Re: Sputter POP and then nothing... Post by ratdog472 on 08/04/06 at 17:30:18 Would it be sufficient to pull that and flush it with gas to get the gunk out? |

Title: Re: Sputter POP and then nothing... Post by Savage_Rob on 08/04/06 at 17:39:11 I really can't say because I don't know the condition of your carb but I know I'd want to at least have a look inside and make a judgment as to whether it warranted anything else. You can usually rejet and do the spacer mod without removing the carb (just loosen and rotate it slightly for access), so an inspection should be pretty easy once the seat and tank are off. |

You never mentioned the condition and age of your bike. From my experience you can accomplish several mods in one round. I'd be intrested in the condition of the bike and what you have done to the bike. What PM do you perform?? |

Title: Re: Sputter POP and then nothing... Post by ratdog472 on 08/05/06 at 05:25:03 The bike is a 2001 with 11,000 miles on it. It is in good condition with the usual slight oil leak from the plug. I've only owned the bike for about a month or so and really have done nothing for mods except relocate the rear turn signals being that the stock ones were trashed. |

I'd suggest a neutral starting point. Perhaps a new plug, air filter, and oil filter. New oil sounds nice as well. A plugged air filter will stop a bike as quicly as a carb problem. Ditto an old battery. Think synchonicity. All the systems must cooperate. Plan a round of mods and PM plan that will make the bike respond. Read the tech section and concentrate on the following systems: Intake, carb and exhaust. Make sure you have new filters, oil, gas, new battery and a decent spark. |

Title: Re: Sputter POP and then nothing... Post by SavageDude on 08/05/06 at 18:55:22 I sometimes get the same symptom (just die off), I have half tank of gas, practically brand new bike 2005. When I switch to PRIME, the beast run normal :o. I suspect that the vacum hose is the cause. Try change that first--very easy fix before attempt to do others suggestion. Its my favorite thing to do--PREVENTIVE MAINTENANCE ;D Good luck Dude. Keep us informed on your progress. |

I've wondered about the gas lines as well. I'm considering clear lines. Best to know what you are dealing with when the systems are basicaly singular. |

Title: Sputter POP and then nothing... (Revisited) Post by ratdog472 on 09/04/06 at 21:07:39 Well with all the thoughts on here I decided to pull the float bowl. In the process I pulled the battery just to make it easier and it needed to have the pigtail put on anyways. Much to my surprise one of the cells in the battery is BONE DRY! Most of the others are below the low mark. Ever have one of those AH HA moments? In the process I decided to pull the bowl anyways and have a looksee at the condition in there. VERY little sediment and decent fuel flow. I also pulled the lines and they seem to be running fine as far as fuel goes. The float is working just fine. It appears that the battery got so far down that it wouldn't provide enough spark to run the bike. The lights were always a little dim and also they would pulse with the turn signals. I should have looked there first. It also goes to think that the bike would start on a roll and run just fine when it was throttled up and not at an idle. It was getting enough juice from the charging system to run fine but not enough to charge the battery which was low. Ok I feel like a dope but let's hope this solves the problem. BTW Walmart doesn't sell a battery for the Savage anymore. |
