Title: Another Carb Question Post by Iono on 08/20/11 at 20:40:00 Here's the deal 1. Carb issue, turned out to be petcock, replaced Petcock and sealed vacum on Carb A. bike ran pretty good. 2. Problems with the carb again when getting up to or at speed not getting fuel sputtering engine, finally conking out. A. Took it to a machanic, he cleaned and it ran pretty good for a bout a week or so 3. Bought dial a jet seem to do the trick, took off down the road all was well for about a mile then BAM!!!!!, same issue, but worst. 4. Took the carb apart the main jet had become unseated and bouncing around. A. screwed back in and cleaned, ran like nuts 5. Finally got my set of Main jets and pilot jets in from Niche cycle supply I change to a cone air filter, I tried from 150-160 main jets, plus 55 piolt jet. A. 160 with 55 seemed to do the trick, the air mix screw was about half a turn out and idled fine. 6. Took off down the road, however in 1st gear getting up to speed it started to bog down, then conked out... A. Now won't start, took off carb put back smaller pilot jet, still won't start. Plenty of fuel in the carb, as every time I've taken it off it is full of fuel 7. LOOKING FOR MY GUN, THIS BIKE MUST DIE!!!!!!!!!!!!!!!!!!!!!!!!! Ok this bike is a savage 400, I want to buy a new carb, as I am located in Thailand they consider this a big bike and have issues working on it or getting me the proper supplies...i.e. I now shop on ebay for my jets and other needs I need some help in purchasing a new carb...I find MX thumper carbs for 250 and a Yamaha 500, but no single cylinder 4 stroke carb, and the only marking on the carb is 00RR... So can someone send me a link to a carb or point me in the right direction as this purchase needs to be spot on as I will have it shipped here..I want to ensure I'm asking the right questions and know what I"m buying or buying the right one.....thanks in advance. One more thing, it looks as if the needle is slightly bent, however slides up and down and needle depresses and springs back when pressure added...Fit new carb..... |

Title: Re: Another Carb Question Post by Serowbot on 08/20/11 at 21:49:37 400 Savages are not available in the US,... so we don't know a lot about them... I don't even know what the stock jetting is in one... but, a #160 main would be very large for our 650's, so I think that's way too much... the #55 pilot is large, too... I think you are likely flooding out, not starving for fuel.... |

Title: Re: Another Carb Question Post by Oldfeller on 08/20/11 at 21:50:44 Yes, in Thialand they abuse their carburetors by using the snot out of them and then having to work on them too much. You did note what the step #1 problem was, didn't you? Bad vac petcock .... very consistent with our step #1 problem here in the USA. If he had paper fuel filtered & Raptored and then had stayed out of the carburetor perhaps the carb would not have deteriorated so much nor so rapidly .... Carburetors take more damage getting worked on than they do by riding them. This one has been worked on a WHOLE LOT, by the user and by various mechanics -- worked on to death sounds like. But I also bet this may be primary transportation that runs a lot more rugged miles than my bike does here in the states. He needs a new carburetor, can he identify the Mikuni part number of his existing carb and maybe we can spot him an equivalent sized carb? 00RR isn't a Mikuni carb designation on any list I can find. From what he has said so far about jetting and model # -- may not be the same main body as ours. This is our carburetor http://suzukisavage.com/cgi-bin/YaBB.pl?board=tech;action=display;num=1098869040 Could he use one of our carbs? Difficult to say without knowing more as he wants it to "bolt up and be right". What size is his intake and exit flanges? How does his throttle cable work the carb? Odds of "bolt up and work right" are very slim using one of our stock 650 carbs. |

Title: Re: Another Carb Question Post by Iono on 08/20/11 at 23:34:32 My carb looks exactly the same, when I tested the jets I started at 150 and then up, yeah your right about to much fuel as now I think I've fouled the plug so it won't start...I will take a picture of my carb and post. Thanks, Kent Oh one more thing, yup this carb has been worked to death, when the one mechanic cleaned it he actually took a file to one of the arms for the float pin and went to town on it....man this is so much fun |

Title: Re: Another Carb Question Post by Iono on 08/21/11 at 00:14:30 The Carb is a Mikuni, however I cannot see the part number all it says is made in Japan on one side and Mikuni on the other, the brass at the bottom of the carb was for the dial a jet, which I plugged...I did close off the vac inlet and added a normal pet thingy, not a raptor...please see photos.

Title: Re: Another Carb Question Post by Oldfeller on 08/21/11 at 02:13:22 Kent, go to the marketplace and buy you a good used carburetor from one of the folks there. A stock Savage carb will "likely" bolt up and run, it looks like. It will be "within range" of what you have done to your old carb, actually a little leaner than the huge jets you have been running. Do you run a fuel filter? Have you replaced your stock Suzuki petcock with a Raptor yet? Doing these two things before bolting on your new carb will decrease the odds of you having to go into it again (it will last longer for you). |

Title: Re: Another Carb Question Post by Oldfeller on 08/21/11 at 04:14:47 Go to the general category heading of this forum, you will see Marketplace -- you can buy a carburetor there from someone breaking down a bike. Here is an ebay carb service that seems to be pretty pricey http://cgi.ebay.com/ebaymotors/SUZUKI-LS650-CARBURETOR-REBUILD-SERVICE-CARB-REPAIR-/360378085102?pt=Motorcycles_Parts_Accessories&hash=item53e8352eee That is not a fuel filter -- that is just a screen. This is a fuel filter. http://suzukisavage.com/cgi-bin/YaBB.pl?num=1211846392 |

Title: Re: Another Carb Question Post by Iono on 08/21/11 at 05:11:16 Thanks for the info, I'll look into a fuel filter here and research the carb issue. |

What I noticed was that replacing the pet thingy did nothing to help the carb problem. All you gotta do is add this one to the list. Apparently even Thailand has been reading all the posts here of how replacing the pet thingy fixes everything ! :o |

Title: Re: Another Carb Question Post by Oldfeller on 08/21/11 at 09:43:41 Routy, read on to what he had to say about having to replace his petcock twice before he finally got a simple manual petcock that worked right. He admits his current carb issues mostly stem from having people try to fix his carburetor multiple times (back when it wasn't necessarily the carb itself that was the total illness). Now, after the grinder man got into his carb, yes his carb is dead (tortured to death by Freddie Kruger and his file fingers) Routy, you still don't have a list -- you have never shown any evidence of the first Savage S40 or LS650 carb issue that didn't start out as a petcock mess to begin with. (this one started out as a petcock anyway, so it doesn't help you any) And, if you think this is one, you are simply mistaken. ;D Or else were mebbe all the rest of that non-list possibly non-650ccSavage examples too? I thought we were talking about 650 Savage motorcycles, not "other" cycles. ;D Heck, you'd be like Bill -- trying to justify his point with a 1966 Moto-Guzzi ================ Drums -- you got it in one. The persons he paid to fix it who took a file or grinder to his carb insides didn't have a clue what they were doing. After they screwed it up, he tried to get it going again and he now knows he need a fresh carburetor as he is fed up with the current one and considers it about worth a bullet. If someone sells him a good working condition carburetor off a running breaker bike, he won't pay more than an arm to get his 400 going again. |

Title: Re: Another Carb Question Post by Routy on 08/21/11 at 10:16:57 OF I don't keep lists, nor do I even try to use the terrible search here. But I have read of several that raptorizing did not help a messed up carb problem. Sorry if you missed them. So this one too,... he raptorized it, and it still had carb problems afterwards. IT DID NOT FIX HIS carb problem,......it NEVER fixes a carb problem,....and even tho it may have needed a pet thingy because unlike the Suzy, the china one are no good......???? I don't know about that. My point is,.......unlike you, I would never tell some to raptorize, just to elliminate a problem that mite happen someday in the very distant future, much less tell them to do away w/ a saftey device. In reality, the vacuum hose is most times the problem,....seldom the diaphram in the pethingy, but I'm sure you already know that. And yeah, because of all the politics here, the pethingy get blames for every float and float valve that malfunctions. No problem,....I agree to disagree,....not a problem. |

There are so many ways to screw up a carb. If someone isn't proficient on the type of carb he/she is working on, just taking it apart and putting it back together can make it worse. "I have rebuilt many carbs in my day, and have never had one turn out worse than before I started. " I wish I could say this. The first carb I screwed up was a Rochester 2GC on my Dad's 56 Chevy in 1959. Of course I was only 13, but I was "blessed" with the certain knowledge that I could fix anything. After all, I had been working on bicycles for years!! ::) Anyway, I can understand completely how someone could say that a lot of carbs are damaged just by working on them. You need the proficiency, the tools, the parts, and a good place to work on them in order to keep from causing yourself a lot of heartache and misery after the "rebuild." |

Title: Re: Another Carb Question Post by Serowbot on 08/21/11 at 11:01:49 Routy,... In my Tech post, How to check your petcock,... (http://suzukisavage.com/cgi-bin/YaBB.pl?num=1251932429/1), I show how to test a vacuum petcock... I also list all the options available to fix it... Testing the petcock first is just smart troubleshooting... (...if your TV quits, the first thing to check is the wall outlet)... otherwise you may be tearing in to something that ain't broke... You have two, relatively new bikes without a problem,... yet. They will,... at that time you will do the test and choose your preference to fix it... (probably buy an $80 vacuum petcock). Fine... Other people want a cheaper, simpler, sturdier, option (Raptor)... Fine,.. their choice... A vacuum petcock is not a safety device,.. it is a convenience... (you don't have to turn the knob)... If you are willing to turn a knob,.. a manual petcock is safer... (it has no vac line to leak)... There is the theory,.. that if you have an accident, a vac petcock will not allow gas to spill... (this assumes that your engine dies, the petcock stays intact, the tank is not ruptured, and the tank vent don't leak, and that the bike falls on the left side)... could happen,.. but does not have the makings of a safety device... The reason the Raptor is particularly popular on this bike,.. is that this bike appeals to the old school, simple, efficient, rider... No high tech stuff... air-cooled, one carb, one cylinder, no digital stuff... Simple mechanisms are more reliable than complex ones.. and are easier to troubleshoot and fix... At the time that a part needs replaced,... many people would prefer a cheaper, stronger, replacement... Especially since the original has just failed... When a manual petcock fails... it just starts to weep a little around the knob, instead of flooding your engine, and it is fixed with a $3.00 gasket... There are legitimate reasons for replacing a weak part with a more dependable one... even as a preventative measure... The day that you find yourself brokedown on the side of the road,.. these things will occur to you... Just like Versy's pinned cam adjuster,... I feel better knowing that it's in there... One less chance of being stuck on the side of the road... ;)... |

Title: Re: Another Carb Question Post by drums1 on 08/21/11 at 13:22:47 Gyrobob. My 1st carb also was a Rochester 2GV, off my old '68 Nova. I followed the destructions and never had another problem with it in 3 1/2 years. Sold it then. Subsequent carbs have included the lovely GM 4 barrel, several times on several different cars, something off an old Ford Gallaxy, the one on my '74 Ford van, and this one here on the Savage. It does take a degree of mechanical knowhow, but I'm also a stickler when it comes to following directions. Ya, if you just dive in half-witted, things are bound to not go right. |
|
Title: Re: Another Carb Question Post by Oldfeller on 08/21/11 at 15:40:03 Yup, I remember when car carb rebuild kits were sold at every auto parts store and they came with VERY GOOD STEP BY STEP INSTRUCTIONS on how to set the float level and every other little detail of the rebuild process. |

Title: Re: Another Carb Question Post by Routy on 08/21/11 at 15:49:06 Bot, When the vacuum line leaks, it leaks vacuum, not gas, therefore is NOT dangerous, but is a very good reason to starve for fuel under hi speed/WOT,.....ok,..... I give you that. Not to mention in the case of an accident, the vacuum pethingy IS a saftey device IMO. With a life expectancy of at least 10 yrs, (why not??.....other diaphram operated stuff last 10-20 yrs) I am guaranteed that no fuel will flow from my tank,.....overflowing the carb, and run gasoline on the floor of my garage, not very far from my gas fired water heater ! Now, can you say the same thing for your raptorized bike setting right alongside it,.....that you know you're not always (if ever) going to shut off the gas,.....no one ever does. I will always believe it is a valuable saftey device, especially for gasoline fires. And I will never believe it should be changed out just because it mite cause a problem some day. Same as I don't believe in throwing jets at..... or hacking a carb just because I changed a muffler or air cleaner. But like I told OF, its ok,....we disagree,......not a problem,....really, its ok ! ;) |
|
Title: Re: Another Carb Question Post by Oldfeller on 08/21/11 at 16:07:27 No we don't -- I don't think you should change your petcock unless you are having issues that drive you to do the Serobot test and you fail that "fairly easy to do" test. Having failed it, your choices are to replace the vac line and give her a whirl and see if you are good again -- if so then GREAT, you are fixed for right now ...... but .... but, then you know you got the second set and third set of vac petcock symptoms to look forward to down the road a piece (the one about the diaphragm getting so stiff a fresh vac line won't fix it and the one about the diaphragm getting a crack or pinhole and losing suction/passing gas to the sump through the vac line). Plus you likely need to replace your vac line yearly to make sure the vac line itself doesn't come back to haunt you as that will likely happen again a couple of times before stiffrubberitus or leakus maximus actually shows up to finish you off. :( ============================= Raptors don't have all this fun hanging over your head all the time. Vac petcocks cause people to get stopped by the side of the road or causes them to be signaled they need to buy gas when they have a half a tank or more. Raptors don't do these things. And so far no one has put gas into a sump because of a float needle failure when using Raptor either (although I am sure eventually that natural carb float/needle valve failure mode will occur and a Raptor won't stop it). Seems strange that a vac petcock won't stop it either but the vac petcocks are showing the gas in the sump failure mode at 7 to 0 right now compared to the Raptor. Perhaps this is because the vac jobbie has two ways to do it and the Raptor only has one? You don't mind me telling folks the above facts, do you? They are facts you know. ============================= Routy, anything up above not factual? |
|
Title: Re: Another Carb Question Post by Oldfeller on 08/21/11 at 16:39:07 Now, this is a question -- I don't know the answer. How do you know the vac petcock is really shutting off the flow of gas when the engine is off? Is there a test to see if the vac petcock is actually working correctly? If so, what is it and how often should you do it? I mean, if we have stiffrubberitus going on that won't allow gas to flow freely through the valve, is the converse possibly true as well? Diaphragm won't flex to allow the valve to close completely under the same little bitty weak spring pressure that it can't overcome to open things up? How would we know? :-/ Logically if one is occurring then how likely is the other? But how would you test for it? |

Title: Re: Another Carb Question Post by Iono on 08/21/11 at 16:59:23 Ok WTF, I found a LS650 carb on ebay for $25.00, put it on my watch list, then I followed the link for the carb rebuilding service...then this morning I go to look at the service and it now has LS650 carb rebuild for $100.00, then I go back to the LS650 carb for sale and it is gone....who on the site provides the service and bought the carb? Too funny |

Title: Re: Another Carb Question Post by bill67 on 08/21/11 at 17:09:46 Over 150000 miles in 40 years never had to take a carb apart,never had a pet thingy go bad,never had to replace a hose.Around 14 difference motorcycles.Nor has my brother with over 200000 miles.The only thing I can say they were all kept inside. |

OF, I really am surprised at this question coming from you. You really don't know how to check if the valve is really shutting off ?? Tell me you're kidding ! Well, how would you check to see if a raptor in shutting off :o Yes, I question a lot of your factual information about all these diaphrams failing in 10 yrs old and less bikes. But then, you have been here a lot longer than I have. And I won't ask for any proof of all your facts. It is plain to see that you are determined to pick away at every part of that valve, why I don't get, and don't care anymore.

Bill, how would keeping inside make the diaphram valves last forever. I'd bet the fact is that there is not near as many failures as this site pretends.

Title: Re: Another Carb Question Post by Oldfeller on 08/21/11 at 18:33:05 Routy, this is your chance to shine. You believe in the vac petcock and you now have a chance to develop a test so folks will know that the shut off vac return function still works correctly. I mean that is your main interest in the things, right? Safety first? Prove that the safety aspect still works. How will you apply vac? How much vac matches what the bike puts out? How much gas should it flow when it is "on" over what time? How quick should it stop? How many drops coming from a stopped vac petcock's carb bowl infeed line constitutes failure? How many drops coming from the vac line constitutes failure? Good luck there buddy -- until you propose your test and prove it out somebody might have license to say "Sorry, nobody really knows if a vac petcock really cuts the gas off each time or not." And that would be a fact. ======================== All the junked vac petcocks were taken off by folks who had very good reason to think the "vac on fuel on" function on their bike wasn't operating correctly. Their bikes stumbled and died. Then they did Serobot's test and the vac petcock failed it. Then they verified this lack of correct vac petcock function by replacement, and the bad stuff stopped. Symptom, Test then Verification. Pretty solid method there. |

I agree. When I do a carb, I spread out a large clean cloth (an old sheet maybe) and do everything as if I were doing brain surgery. It keeps things clean, helps to keep a visual on tiny parts, and it slows down things that like to roll. Snack sized baggies are handy too. Compressed air is VERY helpful,... and if you don't have a compressor, just use one of those pressurized cans (Dusters?) sold for blowing the dust out of computers. I've also learned to keep a digital camera handy,.. taking a zillion pics as I go along to make sure I can put it back together exactly the way it came apart. That camera has saved my gluteal protuberance many times. |

Title: Re: Another Carb Question Post by drums1 on 08/22/11 at 06:54:17 For OF and Routy...I had petcock problems once. Bike was stumbling, dying, and flooding the carb. First I replaced the needle and seat. I had to go back in and recheck it as it was still flooding. Once I fixed that problem, I did Serowbots test and determined it was, indeed, the petcock that was at fault. I got the rebuild kit and installed it. Bike did the exact same thing. Yes, I replaced the vacuum lines too. I didn't have the $ for a Raptor at the time, so what I did is I removed the vacuum line altogether, plugged the carb end and the petcock end of vacuum line connection, and I put it on prime. I have been happily (almost) riding this way ever since. No flooding, no stumbling, no dying. And I don't shut it "off" when parked. (so I know the needle and seat are working properly) I may get a Raptor someday, if I have the bike long enough. |

Ok, if the carb was flooding while running, it is not coming thru the diaphram. It had to be coming thru the float valve. But you fixed that. Then the diaphram really was bad ?

Title: Re: Another Carb Question Post by Oldfeller on 08/22/11 at 08:57:01 Troubleshooting them durn vac petcocks sure can get confusin' ..... You works on them and works on them and they still let you down in some new way that you thought you had stopped. Poor Routy -- tell the nice Drums1 man how to test analyze and fix his design & materials flaw free vac petcock, Routy. Succeed without a total kit rebuild and I'll eat my bite of musty crow meat and spit out the rest of the mouthful of greasy black feathers .... He's willing to work with you -- man, what an opportunity !! Once you admit your total defeat however, then it is the Raptor Party's turn at bat. And if we succeed where you failed, guess what you get to eat? :) fair is fair after all ..... he'd insist that I eat it |

Title: Re: Another Carb Question Post by drums1 on 08/22/11 at 18:21:30 OF, I did do the total rebuild kit on the vacuum petcork. With new vacuum line, petcock rebuilt, new needle and seat, and fresh gas, it still ran like yak poo until I put it on prime and eliminated the vac hose. (plugging both ends, of course) It made no sense to me at the time, but it's basically running the OE petcock as if it were a Raptor. It works, at least for now. |

Title: Re: Another Carb Question Post by Oldfeller on 08/22/11 at 18:25:26 Then you've have done everything Routy could ask for (and the rebuild kit did't fix it ??) Wow. Running it like a manual petcock did work though. Interesting. Well then, wanna eventually try a Raptor so you can get your reserve function back? |
|
Title: Re: Another Carb Question Post by drums1 on 08/22/11 at 18:30:24 I thought the Raptor had no reserve? (on-off) I haven't run out of gas yet running it this way. I check that before every ride. And I never go far enough to use the whole tank, since I bashed the motor in. I don't miss having reserve, I just remain aware that I don't have it. |

These have a vacuum actuated decel valve (it gives a squirt at high vacuum during decel to ease backfires)... ... an accelerator pump is usually mechanical, and gives a squirt when you gas it... (for less hesitation at launch)... Almost opposites... ;)... |

Title: Re: Another Carb Question Post by Iono on 08/25/11 at 20:03:06 I've been in contact with Niche Motorcycle supplies, they have looked into a good replacement for my 400cc engine, the best bet looks to be TM36-68 pumper carb...I'll look into the throttle hook up, I don't know what the difference is, but will make the inquiry. Thanks |
