Title: Daily commuter stalled and won't start Post by Johnnyblade on 09/23/15 at 05:17:47 Hi guys, I read a bit here about the petcock issues and wondering if this qualifies. I have a 2007 s40 that is new to me. No service records with it. Bought with 6400 miles on it. Had an oil change and new tires. I put about 600-700 miles on cruising around and driving to and from work in heavy traffic. Yesterday when I got home I noticed a few drops of possibly gas comming from the black tube that comes down near the battery tube. Some black gunk at the end of the drain tube as well. This morning I went to commute. I let run 5-8 minutes as I geared up. Went about 1 mile and stopped at a stop sign (second stop sign). I noticed the engine sputtering and then...stall. I checked my gas. Plenty. I had trouble starting it. I was able to start it with the choke all the way on and then went another mile and it lurched and stalled again. This time I can not start it at all. Any ideas? |

Title: Re: Daily commuter stalled and won't start Post by Dave on 09/23/15 at 05:33:38 First of all....don't let your bike sit and idle for 5-8 minutes. It is better to start up the bike, run it for about 30 seconds when you are sitting on the bike, then ride off gently for the first few miles. At idle the bike has low oil pressure and is not pumping a good amount of oil around in the engine....and we are also beginning to form an opinion that while the bike is leaning on the sidestand and tipped toward the left....the right side (exhaust) cam lobe and rocker may not be getting enough oil. The lack of air flow over the exhaust also tends to turn the pipe blue. This rocker damage may have been from excessive idling while on the sidestand and/or the use of car oil in the engine. http://i61.tinypic.com/10ymec3.jpg Second......the black tube at the bottom of the bike is supposed to have a cap/plug on it. It is not supposed to be open all the time - you remove the plug when you change the oil, and drain the tube and replace the cap. Running with the tube open can allow unfiltered air to enter the engine. Third....if you are getting fuel dripping out this black tube, it is an indication that either your petcock is failing, or your carb has a needle/seat in the float bowl that is not sealing properly and overfilling the float bowl. Fourth.....do the test on the Raptor and see if it is working. Here is the link to the test. http://suzukisavage.com/cgi-bin/YaBB.pl?num=1251932429/1 |

Title: Re: Daily commuter stalled and won't start Post by Johnnyblade on 09/23/15 at 07:51:17 Thank you very much. I will do the tests when I get home today. Where can I find the plug (is it?) For that black hose comming down? |

Anything the plugs the tube fairly well and doesn't fall out would work. It is not under any pressure. Golf tee, shaved dowel, bolt/screw. Secure with hose clamp. |

Title: Re: Daily commuter stalled and won't start Post by Johnnyblade on 09/23/15 at 10:33:36 I called a dealership looking for a cap before I saw the response. The tech there said I shouldnt cap the hose because it's the "fuel tank vent hose." He told me he wouldn't put a 660 raptor on the s40 because it will cause the crank case to get flooded if I forget to turn off the valve? Is he crazy or did I misunderstand him? I haven't worked on motorcycles at all and cars very little (except a 1975 Plymouth fury, which is a little different by today's standards). |

If your float sticks, yes the excess fuel will spill into your crankcase. I turn mine off but have forgot on occasion. I check the oil before I start the bike to be sure that there is no "extra" oil that I have not put in the bike. Also, if your OEM petcock fails, the same thing will happen! The "puke tube" sticks out below the motorcycle close to the ground a bit before the rear tire below the battery. |

Title: Re: Daily commuter stalled and won't start Post by Johnnyblade on 09/23/15 at 11:29:21 So the "puke tube" is what I shouldn't cap right? |

the puke tube, which comes out the bottom of the air box should be capped otherwise you get oil on your tire, not good for traction. There are 2 carb vents that shouldn't. these are no where near the bottom. your tech may have been thinking of squid bikes that do have overflow tubes hanging to the bottom, but they are small. and our vent tubes are stuck up into the frame above the carb. |

Title: Re: Daily commuter stalled and won't start Post by justin_o_guy2 on 09/23/15 at 19:05:36 Another example of why we don't take these bikes to dealership mechanics. How can a mechanic be that ignorant about how stuff works? |

Title: Re: Daily commuter stalled and won't start Post by Johnnyblade on 09/24/15 at 20:09:15 I tested the vacume hose. Man that was hard to get off. No leak there. Checked air filter seems fairly clean. Before I do the cap and prime test is it possible to take only the carb fuel cup off to check for dirt? Would I have to completely drain the tank before doing this due to not being able to turn off the stock vacume petcock? Thanks |

Title: Re: Daily commuter stalled and won't start Post by justin_o_guy2 on 09/24/15 at 20:31:17 IF it's working right,, it only passes fuel when vacuum is applied. If you haven't opened the drain under the carb, dump it in a clear container. If it's empty, the bike won't run,, that's why there is a Prime position on it. Put it on Prime , maybe the petcock is messing up. Any It won't start issue requires giving it a known fuel. A squirt of ether at the Air intake. Just a bump, hit the starter And all problems that are Won't start wear the battery down,, so, know what the voltage is, try to make it bump, anything, just a promise, a tease, and look at the fuel from the bowl. |

Title: Re: Daily commuter stalled and won't start Post by Johnnyblade on 09/25/15 at 05:03:15 Also...my air filter seems dry. But... stinks of gas |

Have you checked the oil? They can sure get gas in the crankcase. I don't know how old the filter is or how long it would smell,, One thing that Is known, the stock petcock is a common source of oddball problems and cheap to replace. If the gas got in the oil or if you are concerned that it did, an oil change is cheap compared to peace of mind and pieces of engine. |

Title: Re: Daily commuter stalled and won't start Post by Johnnyblade on 09/25/15 at 13:44:01 Doing an oil change today. Gonna do the oil test on a bussiness car won't have an oil filter available today. Drain the gas now to change to a raptor. Is it normal for the gas to only come out in the prime position? |

Title: Re: Daily commuter stalled and won't start Post by verslagen1 on 09/25/15 at 14:08:38 Yes it's vacuum controlled |

Title: Re: Daily commuter stalled and won't start Post by Boogie_with_Stu on 09/25/15 at 19:37:19 Funny story ( not really)...when I got my 2003 she had been basically sitting for 4 years. Started occasionally and driven around the yard, thats it. Petcock was in OFF when I picked her up. After a few days driving her, I couldnt figure out how my oil level went UP. I checked it each time that I rode and on the 4th or 5th ride it was covering the whole observation window. I figured I just didnt have the bike level enough. Bike was having idle issues so I just moved the petcock to RES, no harm no foul...right? ::) Luckily, I found this forum while looking for info on the idling problems. Long story short, I had a bad petcock. there was well over 10 oz of gas in the crankcase. Air filter also stank of gas. Replaced with a Raptor and new air filter, then changed the oil. The first of many "wins" from the family here at SuzukiSavage.com. |

Title: Re: Daily commuter stalled and won't start Post by Johnnyblade on 09/26/15 at 03:35:08 Update... I changed the fuel line. Replaced petcock with raptor, plugged vacume port, changed oil. So far starts and sounds fine. A little "wooshing" noise though. Gonna ride it today and see how it feels/responds. Couldn't see anything faulty with the petcock. Hard to tell with out a vacume pressure gauge. Will keep you all posted. Thank you guys and gals for the patience wi th this newbie. |
