Title: Stalling/won't idle/runs fine Post by Dragonfly on 09/10/10 at 14:37:56 Two days ago I started my bike as usual using the choke it was 60 degrees out. I went to the post office about 1/2 mile away, stopped got mail, started and drove about another 1/2 mile and my bike started to lurch a little with the throttle steady in 3rd gear at about 20 MPH (school zone) then about a 1/4 mile later I backed off the throttle to turn off and it stalled totally, I tried to restart but would start and die I held the throttle on and started it and basically drove it by pulling in the cluch and keeping the revs up whenever I had to slow down. It worked fairly well but I stalled it two more times the final time I switched it to reserve not prime and put more gas in it but the tank was 1/2 full already. So I turned the petcock back to on and it seemed to run fine after that. I started it again last night and it seemed to run and idle fine but never rode it. Then this morning I started it again 42 degrees this morning same thing keept stalling when I backed off the gas. So drove to work anyway (2 miles on highway no stops) some lurching early on but stalled when I pulled into my parking spot. Started it at lunch time seemed to run and idle fine. I dunno never had any trouble before fresh gas, fresh oil, 2500 miles on it. I have a ride in two days with about 400 other bikes and I don't want it to be acting up then. Does any one have any suggestions or similar experience? Ohh ya I have a 2008 S40. |

Title: Re: Stalling/won't idle/runs fine Post by spacepirates on 09/10/10 at 15:42:59 humor me: take it out for a 10-15 mile spin with the petcock on "prime". in fact, let it idle on prime. if it works just fine, then get a raptor petcock. petcock problems are exceedingly hard to diagnose and they always act in weird ways, but if it works on prime then that is what is wrong. another possibility would be a clogged idle/pilot jet, which would mean taking the carb off and cleaning it and making sure the jet is not clogged. seriously though, humor me about the prime. you might not think anything about it, but vacuum petcocks are strange beasts, and they have been a long standing source of pain and grief for dozens of people on this forum. |

Title: Re: Stalling/won't idle/runs fine Post by bill67 on 09/10/10 at 15:46:28 I would put some Sea Foam in the gas,Its a pretty new bike for the pet thingy to go bad,I've never had a pet thingy go bad. |

true, but it is also a pretty new bike to need cleaned out by sea foam. and that also needs a bit more riding to get through the system and clean the gunk (if any) out. still, wouldn't be bad to try both. perhaps at different times to see what fixes what. |

Title: Re: Stalling/won't idle/runs fine Post by circletree on 09/10/10 at 16:00:42 I havea DR350 Dualsport....mine did the same thing when it was fairly new, somewhere around 1000 miles. get the float height checked. DR 350 has the CV carb and vacuum petcock, I've been thru 3 petcocks since new...actually, replaced once, then I got another tank w/petcock when the original got dented. Not really an issue on road but these CV carbs benefit from a t-vent as opposed to the stock vent setup. flood one and you know what i mean! |

If you have the stock jets in it, 42 degrees is pretty cool,Its jetted lean anyway. |

Title: Re: Stalling/won't idle/runs fine Post by Routy on 09/11/10 at 06:59:19 I read no mention of any problems at hi speed,... when fuel delivery demand is at its highest. And it is an intermittent problem. That rules out,...... the petcock, fuel filter, float level adjustment, jet sizes, and any other part of the main fuel delivery. It has to be an internal carb problem, obviously in the low speed/idle circuitry some where,....maybe a sticky slide ?? Seafoam (if you believe in it) would be your best bet for the time being. |

Title: Re: Stalling/won't idle/runs fine Post by Dragonfly on 09/13/10 at 13:04:46 Thank you for all your recommendations. I did the run with no problems we were running pretty high speeds through most of it. When I went to come back home by this time was around 6:30 PM after sitting for 2 hours maybe about 60 dgrees with about 94 % humidity. It did some minor sputtering but managed not to stall. Only about 125 bikes showed up because of the cold and rain. I will run it on prime later to see if that does anything then try the seafoam towards the end of the week as we should have a few more riding days then. Does the gas cap only vent out? I was thinking there may be a little water in my gas. |

Title: Re: Stalling/won't idle/runs fine Post by drums1 on 09/13/10 at 13:19:38 Where does one aquire Sea Foam? I have seen it and used it in the tranny on my car and in the crankcase--I wouldn't put that in my gastank--stuff looks just like tranny fluid or oil. Is there a special one for gas tanks?? I think I'm having the same problem. What if it is the slide sticking? How to clean? I have rebuilt my carb several times--most recently about 3 months ago. |

Title: Re: Stalling/won't idle/runs fine Post by bill67 on 09/13/10 at 13:38:07 Sea foam will clean your slide and lube you pet thingy |

Wally world or any autozone or the like. This is a clear liquid. If you're having issues and have rebuit your carb several times... you might concider putting on a gas filter. But a ounce or two of seafoam every couple of months will help clean it out. |

Title: Re: Stalling/won't idle/runs fine Post by Trippah on 09/13/10 at 16:29:59 As an aside, don't you think 20MPH in 3rd gear is lugging it a bit? If running it on prime helps, replace tubing from tank to carb and see if this helps (making sure there are no leaks). I would hold off changing jets until simpler things are tried first.Then maybee seafoam.. ;) |

Title: Re: Stalling/won't idle/runs fine Post by Bubba on 09/13/10 at 16:45:26 I had cool weather symptoms like you until I switched to the raptor...none since...I did run seafoam through the gas a couple times to see if that would help...it didn't until I switched to the raptor petcock. Just my experience... I still use seafoam a couple times a year in the gas and also in the crankcase just before I change the oil out...definately pulls some crud out for oil changes... |

Title: Re: Stalling/won't idle/runs fine Post by Charon on 09/13/10 at 17:00:07 Did you notice where Bubba said "I did run seafoam through the gas a couple of times to see if that would help...it didn't"? We are still awaiting the report from the original poster. |

Title: Re: Stalling/won't idle/runs fine Post by bill67 on 09/13/10 at 17:06:14 Read his post he said he put on a new pet thingy,Sea Foam doesn't fix pet cocks and hoses with leaks in them. It cleans carbs and lubes them and cleans engines. |

Title: Re: Stalling/won't idle/runs fine Post by Charon on 09/13/10 at 17:40:19 Actually, bill67, I did read the entire post. I chose to quote the part where he said the Sea Foam didn't help, and he actually had to make repairs. That has seemed to be the case on other problems, too, such as the recent thread where the poster posted a picture of a clogged main jet that Sea Foam didn't clean out. As I said before, I am not going to argue with you. Believe anything you want, with or without any factual basis. And by the way, be it noted that YOU are the one who is trying to start an argument. The only thing I have been doing is asking people to post the results if they try Sea Foam. |

Title: Re: Stalling/won't idle/runs fine Post by Routy on 09/14/10 at 07:34:08 I have been an automotive tech for too many years. Auto techs are usually not that fond of additives, altho do believe in some OEM additives. But all this halabloo about Seafoam (not just from Bill either) has had my attention. And notice.... I have not badmouth Seafoam, and even recommended to try it in a case or 2. where nothing to loose. Well,.....ironically, (I'll make a long story short here) I came up w/ an intermittent fuel problem on my 50 hp 4 stroke outboard, that was going to require me to bring it to the Merc boys to (try to) fix......@ $100 an hr, so...........against my better judgement, I bought a can of seafoam. W/ the tank near empty, I mixed it w/ 5 gals of gas (very rich) took it out, trolled it for 5 hrs, cruised it for 45 minutes...5500 R's, and to my amazement, it didn't miss a lick. But it has gone tween 1-5 hrs before, while running good. I took it out again yesterday....trolled 3 hrs and cruised 15 minutes, (tank almost dry) and still it hasn't missed a lick ! Did the Seafoam fix it,...or at least do some good ?? I wish I knew for sure, but right now I still have hi hopes. I will now add 10 gals gas and another can of Seafoam. I will post on it if anything changes. Salmon season is on us here, so I will end up either loving Seafoam, or hating it. BTW, lighten up on Bill,.....for most times he only tries to help. He isn't selling Seafoam ! .......are you Bill ?? ;D |

Title: Re: Stalling/won't idle/runs fine Post by bill67 on 09/14/10 at 08:38:33 Routy try some in the oil on the out board.You will be catching more salmon than you ever catch. :) |

Title: Re: Stalling/won't idle/runs fine Post by jabman on 09/14/10 at 10:13:35 from this i think the concentrated/intensive use of sea foam is best to help solve a problem. mixing a little with a full tank of fuel seams more like a preventative measure |

Title: Re: Stalling/won't idle/runs fine Post by Boofer on 09/15/10 at 20:36:49 This may not apply, but I love Seafoam. I would drink it if it came in grape flavor. (DO NOT TRY THIS AT HOME!) I got mine at Tractor Supply for $7.00. Seriously, about 6 months ago, I started running 93 octane (With 10% Ethanol) in everything I own. My mowers and chain saws and weedeater improved dramatically. My bike has less power and top end dropped about 8 mph, but it, and my cars crank and run better. I did this on the advice of a small engine guy and a friend who uses chainsaws for his livlihood. Lots of people here go to the airport and use credit cards to buy aviation gas for about $4.00/gal. (The pump is unattended so credit is the way to go) I also switched to Rotella Dino at the same time. Just saying..it works for me. |

Title: Re: Stalling/won't idle/runs fine Post by Charon on 09/16/10 at 05:42:02 I used to fly a little, and of course talked with the guys at the airport. Every so often they had to drain gas from airplanes, and they were not allowed to put it back because they couldn't guarantee it had not been contaminated. So they burned it in the airport mowers and the fuel truck. All of them said the equipment didn't run as well or start as easily with aviation fuel. Also, the avgas is leaded, and it will eventually foul your spark plug and contaminate your oil with lead. Changing fouled spark plugs is said to be one of the most frequent maintenance tasks on airplanes. |

Title: Re: Stalling/won't idle/runs fine Post by bill67 on 09/16/10 at 06:07:55 You will have less power with 93 octane ,and with gas with 10% ethanol. and get less mileage,The 93 octane burns slower, same and retiring you spark. |

Title: Re: Stalling/won't idle/runs fine Post by groupus on 09/17/10 at 18:37:53 So ANYWAYS... it would be cool to get back to the original topic so we can help out the poster instead of hijacking it to talk about lawnmowers and airplanes ;D. (seriously, don't ever mention seafoam, tires, or oil here unless you want to sift through pages of opinions). you've heard some arguments for each; if you want to try seafoam, it couldn't hurt unless you need that $8 for smokes or beer. it looks like i'm in the same corner as Dragonfly. the bike doesn't want to idle on RUN, but if i switch it to REServe or PRIme, it seems fine. definitely a petcock based problem. it seems to run fine in RUN at higher rpm tho. Regardless, i'm going to try replacing the vacuum line, and if that doesn't work i have a spare pet to try. updates will follow. i hope this is helpful. one thing i can't figure out is why it works in reserve. prime i understand, but i thought reserve was vac controlled too. anyone know? |

Title: Re: Stalling/won't idle/runs fine Post by Oldfeller on 09/18/10 at 03:30:56 Stock petcock opinions are .... opinions. I can't count the number of "stumbling issues" over the years that have been seemingly traced back to the stock petcock not flowing enough gas for the carb's current demand. (my personal troubles noted along with everyone elses) Raptor petcock is .... removing all shades of this issue forever. |

Sorry Groupus, didn't mean to aid in a hijacking. I just noticed your quote,"Maintainence is as much an art as a science". I like it. We kinda got off the subject by talking about the voodoo (art) we use to keep our bikes running. Sometimes the placebo effect kicks in and we think we have helped, because that is what we want to believe. But when your wife or daughter comes in and asks what you did to make their car or 4-wheeler crank so much easier or run better a little light comes on. Usually when I recommend something like an additive to a friend, I'll give them an ounce or 2 or buy them a can. We all want to help. Sorry again for getting off subject. |

Title: Re: Stalling/won't idle/runs fine Post by groupus on 09/20/10 at 18:24:21 Art, Voodoo, i like it all. no harm done in giving opinions to try to help, I just think we were getting seriously derailed. I've tried additives, including seafoam, and would not discount them. worth a shot, but not exactly a miracle cure. i have not got around to replacing my vac line yet but i know my petcock is toast. i don't think these have been posted yet, but here are 2 helpful links on testing the petcock and converting it to manual: http://suzukisavage.com/cgi-bin/YaBB.pl?num=1251932429/2#2 http://suzukisavage.com/cgi-bin/YaBB.pl?board=tech;action=display;num=1113631600 good luck! |
