Title: Another Raptor Petcock Convert Post by ATLjan on 05/14/11 at 19:32:09 Installed mine today and MAN what a difference. My 2004 w/nearly 8k had been stalling. Rode 100 miles after install and she ran like a dream!! Super easy install and I capped off the vacuum line ala Digger. Thanks everybody for the tips AND the Ron Ayer's link to the part. |

Title: Re: Another Raptor Petcock Convert Post by papi_ocho on 05/14/11 at 21:02:14 How much did it cost ya? My bike is a 06 but it just broke 1500 miles. Kinda thinking if I don't need it, I don't want to spend green on it |

Title: Re: Another Raptor Petcock Convert Post by Routy on 05/14/11 at 21:25:29 Good that it fixed your problems. For me, I'll always defend the saftey feature of the vacuum petcock, and I'd probably kit the valve if and when it gives me trouble. |

No, you shouldn't need one yet. It costs around $25 and is easy to install. Makes the tank easier to remove also. But Routy makes a good point about the safety feature. At least if the bike goes down the gas will shut off when the engine quits and if it's working properly you don't have to remember to shut the fuel off when you park it. |

Title: Re: Another Raptor Petcock Convert Post by papi_ocho on 05/15/11 at 06:02:49 I see ::) this is my bike http://suzukisavage.com/cgi-bin/YaBB.pl?num=1305220455 I like safety Routy: whats this kit your talking about? |

Title: Re: Another Raptor Petcock Convert Post by Oldfeller on 05/15/11 at 08:55:53 Petcock war again, I guess. Everyone agrees that the stock vacuum actuated petcock fails and causes trouble for the owner. Some (including me) say jest yank that durn stock petcock unit off and bounce it off the wall a few times in revenge for all the BS it caused you. Others jest love the little trouble prone vacuum sucking gas bleeding not reliably opening little thing, and they want you to spend time, $$ and effort to troubleshoot it and try to repair it. The reason that they give for this is "gasoline in the oil" which does happen when a carburetor float malfunctions. Funny thing, gas in the oil seems to happen more often with the stock petcock than it does with the Raptor replacement. ;D ;D ;D (why? I dunno -- don't ask me to explain the 1,001 ways a failed vac petcock can make your bike run rich -- and then run some of that liquid gas down the vac line to the manifold, then past the piston down into the sump) Now, if you go with the repair it folks, you will get another chance or two later on to reconsider and go with the Raptor replacment folks -- 'cause guess what happens to your rebuilt/repaired vac petcock given enough time and miles ..... ;D Guess which one is cheaper, a repair kit or a Raptor replacement .... And as an added benefit, when you go raptor you can take your gas tank off without having a big hassle. ;) |

Title: Re: Another Raptor Petcock Convert Post by verslagen1 on 05/15/11 at 09:18:46 so |

Title: Re: Another Raptor Petcock Convert Post by Serowbot on 05/15/11 at 09:19:20 Like OF says,... the vacuum petcock causes more gas leaks than it prevents. It is commonly thought of as a safety feature, but I have never read anything official saying so. I don't see it as a safety, but a convenience feature. Can anybody find some advertising or something from Suzuki promoting this a safety feature?... It's definitely not mandated, because many bikes don't have it. |

Title: Re: Another Raptor Petcock Convert Post by Oldfeller on 05/15/11 at 09:43:16 so? ..... is so too ..... you can hear them talk about the vac petcock hanging on to what's left of the gas tank if you wait patiently until the very very end of the video (firemen & people talking in background). ;D ;D ;D "Austin, you are a dumbass for using that stock petcock ..... " [media]http://www.youtube.com/watch?v=w5IWndghJWM[/media] |

Title: Re: Another Raptor Petcock Convert Post by verslagen1 on 05/15/11 at 10:14:54 Seems to me they were talking about the petcock not being turned off and the hose cracked. |
|
Title: Re: Another Raptor Petcock Convert Post by Oldfeller on 05/15/11 at 11:21:40 It was the thin vac hose that goes to the vac port on the petcock ..... Moral of the story is don't smoke while riding. |
|
Title: Re: Another Raptor Petcock Convert Post by verslagen1 on 05/15/11 at 11:43:40 He only mentioned 1 hose on the petcock so it must've been a raptor type petcock. |
|
Title: Re: Another Raptor Petcock Convert Post by Oldfeller on 05/15/11 at 11:49:03 Yep, he did say hose now didn't he? You got a fuel line and a vac hose, so he must be referring to that thin walled vac hose when he said the petcock failure caused the explosion and fire. After all, manual petcocks have been used for over a hundred years now with no unnecessary complications. ======================== Vac actuated petcocks, now --- well their very name is synonymous with complications and troubles of all sorts. |
|
Title: Re: Another Raptor Petcock Convert Post by verslagen1 on 05/15/11 at 12:06:19 If it were the vac line, there are 4 little holes and a rubber valve that it'd have to go thru. The fire there was too big to be from a trickle. |
|
Title: Re: Another Raptor Petcock Convert Post by 2whlthrpy on 05/15/11 at 12:24:06 ummmm.....to each his own. [smiley=vrolijk_26.gif] Great thing is, all the info to correct it is right here. So choose whichever side of the fence you wish to fall on. |

Title: Re: Another Raptor Petcock Convert Post by Oldfeller on 05/15/11 at 14:20:19 We are jest playing around a little bit on a slow Sunday afternoon, there is no direct evidence that that fire came from any exact thing in particular. Other than the gas tank that is .... Heck, once the little dribble from the vac line caught the vapor in the carb vent lines on fire there was plenty of exothermic heat from the gas in the float bowl to get the seat foam and then the whole gas tank involved, and from there the silly tree next to it decided it wanted to play too. ;D |

Title: Re: Another Raptor Petcock Convert Post by ralfyguy on 05/15/11 at 14:26:34 I bought a new stock petcock half a year ago. It runs flawless. Would it run faster with a raptor petcock? |
|
Title: Re: Another Raptor Petcock Convert Post by verslagen1 on 05/15/11 at 14:30:23 I know, just playin' along. Heck, itza squid, probably fuel injected, fuel pump one the bottom of the tank, and no petcock at all. |

Title: Re: Another Raptor Petcock Convert Post by Oldfeller on 05/15/11 at 14:35:33 No, not while your $80 new stock petcock is practically new anyway. But, given another 5-10 years (once the vac diaphragm gets stiff or splits again) then yeah, I think a 5-10 year old Raptor would still be doing excellently (the same exact same way a new Raptor would be doing) while the $80 spent on the replacement stock petcock would be acting about like the original one did, giving your similar troubles to those which caused you to replace it in the first place. Stock vac petcocks are unreliable -- you are tossing good money after bad performance in the long term. =============== I think they said the bike was a BMW, but the kids with the camera phone are idiots who very well might not know a squid from a beemer. |
|
Title: Re: Another Raptor Petcock Convert Post by ralfyguy on 05/15/11 at 18:32:38 I replaced it because it turned really hard. The new one turned nice, for about a month.And the new one now turns about as hard as the old one. ;D |

Title: Re: Another Raptor Petcock Convert Post by Routy on 05/15/11 at 22:50:30 Well, are you just kiddin around or are you's just a bunch of ignorant kids ? The reality of it all is that the diaphram in that petcock is no different than any other diaphram material, whether it be in a carb or a fuel pump, or any other component that uses diaphram material,....such as accelerator pumps in some automotive carbs, and therefore are not going to give any more trouble.....any sooner than any other of those fore mentioned components, and therefore will last anywhere between 10 and 20-30 yrs. Fact is in the first 10-15 yrs, most all the problems is from the vacuum hose deteriorating, not from a ruptured diaphram. So quit you're dam whinin and snibblin about the petcock, when in reality it is no more troublesome than any fuel hose on these bikes. And when the vacuum hose get to the age where it mite split ends, go buy a pc of fuel hose that will last for 20 yrs ! Along w/ mine I know of 3 other bikes from '04 to '07 that have never touched the vac line or much less the petcock, all are still original and working fine. Just amazes how any type of bad running problem out there right away gets blamed on the petcock, and most those times it turns out to not be ! 14 million of these bikes out there, some near 30 yrs old, and you kids snibble and whine about a petcock that fails now and then on a 20 yr old bike. Ok ok, I'm just kiddin around on a sunday evening too >:( |

Title: Re: Another Raptor Petcock Convert Post by Oldfeller on 05/16/11 at 10:03:25 I vote for ignorant kids, personally But at least you aren't bored any more .... .... and you got to play with your old WWI M1A1 to see if you can get it to shoot out as far as your more modern M2 will go spray. (old toys are always a lot of fun to take out and play with on occasion) And BOOOOO!! it's Monday, so we all gotta go back to work (no more fun) ;D |

Title: Re: Another Raptor Petcock Convert Post by ralfyguy on 05/16/11 at 10:11:33 I change the vaccum hose once a year, no matter what. The end near the cylinder head gets a lot of heat and starts cracking after a while. I buy 3/16" fuel hose at O'Reilly's and it's about a dollar per foot. Cheap, easy preventative maintenance. |

Title: Re: Another Raptor Petcock Convert Post by Boofer on 05/16/11 at 18:29:23 FWIW I am a convert. Just need to get a little money in the bank. It seems like I put most of my motorcycle money in the gas tank of my car or truck. But what someone pointed out on here is that my stock petcock is probably not flowing the full amount of gas it could be. Sometimes I need slapping, but common sense usually brings me around. ;D |

Title: Re: Another Raptor Petcock Convert Post by Gyrobob on 08/05/11 at 08:09:57 Oldfeller referred to "The reason that they give for this is "gasoline in the oil" which does happen when a carburetor float malfunctions. Funny thing, gas in the oil seems to happen more often with the stock petcock than it does with the Raptor replacement." While we don't want gas dribbling down into the crankcase, it ain't no big deal unless the crankcase is overflowing with the stuff. In arctic aviation, a "technique" used sometimes by bush pilots is to deliberately mix some gas in the oil before the motor is shut down. This lowers the viscosity of the stuff in the crankcase so the motor will spin over a lot easier in the morning. After the motor warms up, the gas evaporates off and leaves the oil pretty much like it was. |
