Title: Carb Screw - Which Direction? Post by Chris Tipton on 08/02/12 at 11:21:07 I read on here to prevent backfiring on the Suzuki Savage, you should remove the copper plug to get access to the carb mixture screw and adjust that accordingly. I was able to do that with no problems and have adjusted the screw to where my motorcycle runs fine in really hot and dry weather but now that it's getting a little colder, which way do I turn the screw? I am asking which way to turn the screw when it's hot, humid weather and which way for a little colder weather? Yeah, I have no clue! LOL! Thanks! |

Title: Re: Carb Screw - Which Direction? Post by babyhog on 08/02/12 at 16:19:06 Glad you saved me the trouble of looking this up, but I'm still confused. I finally got to ride to work today. I'm popping alot more than I used to. Going to work was about 70 degrees, coming home was around 95 degrees. Popped a little less coming home. Its very humid here. Since Since it popped more when it was cooler and less humid, I thought I should go richer, but then it still popped alot when it was hot and humid. Help? :-? |

Title: Re: Carb Screw - Which Direction? Post by Serowbot on 08/02/12 at 18:18:13 Piglet, Have you checked your header bolts?.. If they come a little loose, you'll pop all over the place.. :-?... |

Title: Re: Carb Screw - Which Direction? Post by babyhog on 08/02/12 at 18:21:56 Good point. I'll do that, thanks. I've also felt a little surging/gasping occasionally but its so inconsistent, I can't pin it to anything yet. I'll go check those bolts. :-* |

Good call Sero! ;D I did the oil change on mine tonight(Rotella 15-40 dino,by the way) and noticed one of the header bolts was a little loose. I've had a bit more popping lately and when I did my "after oil change" shakedown run things were much quieter 8-) ;D. Just proves that it pays to take out the wrenches and check all the nutz and boltz on a regular basis. What do the pros call that...???.....oh yeah! Preventitive Maintenence ;)! |

Title: Re: Carb Screw - Which Direction? Post by Chris Tipton on 08/15/12 at 07:06:42 So, this morning I rode my 1998 Savage to work and it was VERY foggy out and whenever I stopped...my poor motorcycle died. :( I thought I had it running pretty good when I was a little colder in the morning and hotter on the way home but now with the fog...nope! It there any way to fix it so it just runs good without having to fiddle with the carb screw or am I SOL? I've got it where it doesn't backfire at all where it is now too. Thanks! |

Title: Re: Carb Screw - Which Direction? Post by justin_o_guy2 on 08/15/12 at 07:11:37 Remember, a low idle speed kills the head. |

Title: Re: Carb Screw - Which Direction? Post by Routy on 08/15/12 at 07:27:17 I cringe whenever these threads come up about messing w/ carbs for the sole purpose of trying to stop backfire, mainly because it usually ends up w/ little to gain, and a lot to loose when you start hackin the carb ! Just learn to control the backfire w/ the throttle, its easy ! About the time you think you stopped it, it will be back under different conditions. These bike are known for the backfire,.....it means they are running as they are designed to run. All this IMO only ! |

Title: Re: Carb Screw - Which Direction? Post by verslagen1 on 08/15/12 at 07:44:20 sounds like your idle speed is too low. |

Title: Re: Carb Screw - Which Direction? Post by Chris Tipton on 08/15/12 at 08:28:32 @ Routy...all opinions are welcome to me! :) The backfiring I know is normal for this type of motorcycle but it was pretty darn loud though, even when I was trying to control it. So, I figured I'd give it a shot and got it working with no backfiring and just this little issue. It's really cause where I live in Ohio, the weather has been CRAZY! We really had no winter....maybe 2-days of light snow and it's been SUPER DRY this summer! I'll figure it out but it you know the carb screw turns to get it to the factory settings...I'll try it and see what happens. ;) |

Title: Re: Carb Screw - Which Direction? Post by Chris Tipton on 08/15/12 at 08:31:29 @ justin_o_guy2 & verslagen1 - yeah, I was thinking of that too. I know when I first got it, the idling seemed a little fast but it didn't stall but backfired. So, I'll adjust the idling and see how it works. Thanks again all for such FAST and GREAT suggestions! You guys ROCK! 8-) |

Title: Re: Carb Screw - Which Direction? Post by justin_o_guy2 on 08/15/12 at 10:16:48 If it boofs & growls, thats okay, if it goes off like a gun, you may have a leaky exhaust. If the idle is low, pops or no pops, get the idle up. The cost of a low idle speed is way serious. |

Title: Re: Carb Screw - Which Direction? Post by sjaskow on 08/15/12 at 11:22:21 My brass plug is still intact and I can make mine bang like a gun pretty much on demand but I've learned to control it. I've checked all of the exhaust bolts and they're nice and tight. You may want to change gasoline brands. The amount of bang seems to depend greatly on brands. For example, Marathon makes mine pop more than Super America does. |

Title: Re: Carb Screw - Which Direction? Post by Chris Tipton on 08/15/12 at 11:51:54 justin_o_guy2 - I thought it was a leaky exhaust at first and I had it checked out and it was all good. I took it out for a drive at lunch and upped the idle some. It sounds like it's running better and no back firing. :) The real test though will be when I ride it to work in the morning and see how it does. |

Title: Re: Carb Screw - Which Direction? Post by Chris Tipton on 08/15/12 at 11:54:26 sjaskow - I've actually tried different brands and even differnt grades of fuel but it still would backfire like a gun. So, I opted to try to adjust the carb screw and idle screw. Since then, I've had no problems until this crazy weather came about. I'll get it running good without adjusting it soon enough. :) Good suggestions though on reasons it might be backfiring so bad! I appreciate all the help! |

Beag, Are you still rocking the OEM petcock? The reason I ask is that, IME, poor running in cooler wx can signal a sketchy petcock vacuum diaphragm, assuming you are using a vacuum actuated petcock.... |

Title: Re: Carb Screw - Which Direction? Post by Beagle on 08/16/12 at 18:51:50 Yes, I am still using the original petcock but it seems just a small 1/4 turn of the idle screw and I'm doing good. :) |

My position exactly !! [/quote] To eah their own my friend. It seems to running good now, even in the foggy weather in the morning and the hot sun on the way home. So, we'll see if it keeps working well. I really can't go back to the "factory specs" unless I take it to a Suzuki place though and I won't do that as long as it's running good. :) As always though, I appreciate the many suggestions and opinions from everyone. It's nice to have so many people who has experience and advice on this motorcycle! |

[/quote] Interesting, living with a defect to preserve the god like status of the EPA.[/quote] Yeah, you'd think Suzuki could have this fixed so it wouldn't backfire and run good but it's all good. We have so many people on here that have tried different things for anything and everything, so someone will have a solution for whatever ails our bikes. ;) |

Title: Re: Carb Screw - Which Direction? Post by Arnold on 08/17/12 at 09:20:20 Has anyone experimented with different carbs on this thing? |
|
Title: Re: Carb Screw - Which Direction? Post by Boule’tard on 08/17/12 at 09:32:28 I think the most common alternate carb is the Mikuni VM. That one has an air screw instead of a fuel screw. In general, a brass screw upstream of the slide is an air screw (righty richer) and a brass screw downstream of the slide is a fuel screw (righty leaner). |
