Title: idle trouble and plug leak Post by BurnPgh on 08/24/08 at 21:10:26 I know all about the plug leak deal so I'm set on that. Any quick idea what may be the trouble with the idle. It'll idle slower and slower until it dies then I've got to restart it while pulling on the throttle and it wont idle until it gets good and warmed up with me putting on throttle. |

Title: Re: idle trouble and plug leak Post by BurnPgh on 08/26/08 at 20:47:40 sorry. '95 about 12500 mi now. The idle trouble only occurs sometimes. Sometimes in the cool night, or on a really hot day it'll act up. Sometimes not. |

Title: Re: idle trouble and plug leak Post by Digger on 08/27/08 at 20:58:23 Does it happen with the choke on or off? |

Title: Re: idle trouble and plug leak Post by BurnPgh on 08/27/08 at 22:33:54 usually i'll idle it with the choke on, the RPMs will slow over the peroid of 30 seconds until it stalls after which time It wont start with the choke on at all. I'll close the choke and restart it. At that time it will idle very slowly and stall unless I have a wee bit of throttle on and keep it on until its thoroughly warmed up. Sometimes none of this happens. Its usually just fine with 30seconds with choke on, turn choke off and its good. But like i said, sometimes it'll act up for whatever reason. Seems to be more pronounced after I fill up but that could just be my imagination. |

Title: Re: idle trouble and plug leak Post by T Mack 1 on 08/28/08 at 06:33:56 Your idle is too low..... adjust it till it runs ok. It should be noted that the idle spec is a range not a set number (1000 to 1200 rpm) . This is due to the nature of the single cylinder air cooled carbureted bike. Idle speed changes a bit with operating temp and weather conditions. That's why there is a easy idle speed adjustment...... On a side note, it may sound neat to have a low idle, but at 1000 RPM the oil pressure is only 2 PSIG. The other day I took idle down to 900 and the needle on the gauge almost touched 0 psig...... |

Title: Re: idle trouble and plug leak Post by Digger on 08/28/08 at 20:46:30 If you continue to have problems, check the petcock vacuum line. It should have zero smell of gas. IHTH! |

Title: Re: idle trouble and plug leak Post by BurnPgh on 09/06/08 at 20:15:48 Okay, I upped the idle a little more than a week ago and it did fine...until now. I topped the oil off a few days ago and checked it today before i took off so I know Im not low on oil. I AM due for an oil change. I've been topping it off but Im at about 3k mi on it. Tomorrow I'll check the vac line for gas and change the oil. As long as Im changing the oil I'll check the oil filter and make sure it isnt fouled with plastic from the cam chain guides (please god no). I REALLY dont want to have to take the gas tank off and check the plug but i suppose it could be fouled. SO....barring gas in the line, old oil, clogged oil filter, or fouled plug what could I be looking at? |

Look at the weather. I am constantly amazed at how the weather affects the way my bike runs. Especially temperature. We've had a few cool days around here (39 degrees the other morning) and the bike is running like a striped-assed ape. I'm thinking it's a little too rich on warmer days, 'cause it sure doesn't jump away from stop signs like it will right now. |

Title: Re: idle trouble and plug leak Post by eanon on 09/07/08 at 07:54:55 Yup. My bike runs a LOT better when it's cooler outside..... |

Title: Re: idle trouble and plug leak Post by bill67 on 09/07/08 at 08:36:47 I've have mine a little lean,and it feels a little stronger at 85 degrees,than at 60 degrees |

Any black smoke at idle? Could be rich... Also the carb slide and diaphragm, could be sticky. But check the other stuff first. |

Title: Re: idle trouble and plug leak Post by BurnPgh on 09/07/08 at 12:32:08 No gas in the vac line. Oil changed. Oil filter good. Didnt check the plug. No smoke. Seems to happen usually right after I fill up. I fill with the bike on the sidestand up to the bottom of the filler neck. When the stalling happens The first thing I do is take off the gas cap and switch to prime. No whoosh of air in or out but the bottom of the cap is usually covered with gas so I suppose I could be submersing at least one of those little vent holes and creating a vapor lock. |

Title: Re: idle trouble and plug leak Post by T Mack 1 on 09/08/08 at 16:34:39 Hmmmm interesting pprobelm. I don't think it's the vent holes in the gas cap. they shouldsuck air in no problem, that is if they are clear & clean. BurnPgh, Where are you located?? I vaguely remember you telling us in another post but the mind isn't as sharp as it use to be. T Mack east side of PA. |

Title: Re: idle trouble and plug leak Post by BurnPgh on 09/09/08 at 13:44:59 Im about 10-15miles east of Pittsburgh PA |

Title: Re: idle trouble and plug leak Post by BurnPgh on 09/09/08 at 23:35:46 Filled up again today. Same deal. Im pretty convinced the cap isnt venting properly. I dont know why though. Ive always filled according to the same "ritual". Pull in, kill switch, kickstand, dismount, petcock to "on" from "res",key to "off", gas cap off, fill to edge of neck with bike still on the kickstand. It just started doing this a few weeks ago. |

You are over filling the tank if you are going to the filler neck while on the side stand. I'm surprised you don't have wet pants from fuel running down the tank. See http://suzukisavage.com/cgi-bin/YaBB.pl?num=1218765878 |

Title: Re: idle trouble and plug leak Post by T Mack 1 on 09/10/08 at 11:06:07 The bottom of the cap will be wet when riding a short distance after fill up. The gas sloshing around will do that. I've already OOP'S and overfilled because I was talking to someone about the bike. Then when the gas warmed up to air temp (verse the 58 deg F gound temp here in east-side PA), it dribbled out a little bit. I'm not convinced that is you're problem. BUT..... I've been known to be wrong. Get a can of WD-40 or Liquid Wrench and spray the little tube thing down the hole (they both burn so it will not hurt the gas). If it doesn't find a way out, you've got a clog. |
