Title: Caeb problems. Please help!
Post by mkirch on 04/12/16 at 14:54:13

I recently bought an 06 s40. Happy with it so far but at first it was backfiring and wouldn't stay running without choke half way out. I ordered a carb kit and changed out jets and cleaned it all up. Problem is the jets I got and took out were different. U did some look I g and matched them as closely as I could. Now it runs a little better but still backfires and stalls when I go full throttle. Seems to only do this a mile or two down the road. Runs great in garage.

The muffler has its baffles cut out so I can assume that has something to do with it. I should get my stock replacement muffler Thursday and I want to re jet to stick. Can anyone tell me exactly what jets I need? I have two sets right now. As far As I know the Caeb is stock. Bike has 1900 miles on it and I'd like it to run like it!

"Seems to only do this a mile or two down the road. Runs great in garage. "

Might be a vacuum petcock problem or a leak in the vacuum line to the petcock. When under the load of driving, low carb vacuum might not be strong enough to hold an old, stiff petcock diaphram open. The result is not enough fuel supply as fuel is used faster than the carb float chamber can refill. Check the vacuum line from carb to petcock for leaks, then go for a ride with the petcock set to PRIME and see if there is any improvement.

Ok I'll have to try that when I get it back together. Do you know anything about the jetting? I have 4 jets and every diagram I look at doesn't seem to match what I have. Unless I'm just not looking at it right

What did you pay for the muffler?
Letting it idle on the sidestand is not good for the cam.
A low idle doesn't make enough oil pressure to keep the top end alive.
A Dyna muffler is cheap, sexy looking and sounding and is easy to tune the carb to.
Leaks in the exhaust make backfires.

I got some muffler off eBay for 200. Probably paid too much but I wanna get it together. I just took the exhaust apart and it all seemed great. I'm just gonna put it all to stock so it runs good. I'm going to try the petcock trick and call the dealer tomorrow for jetting

You would be ahead to calm down. Ask here before you talk to the dealer. Jets are available here, sometimes Dyna mufflers, too. You spent at least $150.00 too much, and, didn't get the best muffler.

Title: Re: Caeb problems. Please help!
Post by cheapnewb24 on 04/12/16 at 17:34:46

Justin has a point. Think through this. You can get a Dyna muffler for less than 50 bucks (more around $20-$35.) The jets are a few dollars a piece+ shipping. If you can find the right place like I did, they're liable to give you some little #4 washers for the white spacer mod. Get 5 of them, though you'll usually use 2-3 of them. You can get a carb kit for around $16.

I recommend a 147.5 main jet and 4 #4 washers for purely stock setup with stock muffler. I personally haven't tested that setup, though. I am running even richer with a 150 main with 3 washers, and it runs great, and the noise level is reasonable, but gas mileage isn't what it used to be. :-/ I plan on installing the Dyna muffler, though. The fewer washers, the richer, and 5 of them is close in thickness to the white spacer (possibly a little thicker :-/). It is known that the stock setup tends to be too lean, to the point of being a little dysfunctional for some. Don't be afraid to go 1 click richer. In fact, the Savages from the 80's ran with a 152.5 main jet, which is 3 sizes larger. That is with pretty much the same setup. The experts here are free to correct me if I'm a little off here.

Don't fool with dealerships. It is well known that the Savage is a very simple bike and is relatively easy for a newbie to work on (like me ;))The Savage carb isn't that hard to tune. I've had mine apart (at least partly, if not mostly) a time or two. You may not know what every little passage does, but it's not brain surgery. There is only one carb, and my bike has been very reliable and easy to start, even in the winter. These bikes are not tempermental in my opinion. Dealerships, known as "stealerships" by many here, will suck you dry. You can spend more money at a shop than the bike is worth. If you need a part now and can get it for a competitive price at a dealership, then fine, do it. Otherwise, you need to learn to fix your own bike. Of course, if you like spending money more than working hard to save it, then feel free to burn it. ;)

If you want to know something complicated, try a Honda Shadow from the 80's. ::) Twin carbs, electric fuel pump... And I have the duty of fixing my Dad's carbs. ::) And that thing is tempermental! Run the battery dead just trying to crank it. ::)

I didn't know that about the muffler. I don't know much about this bike or bikes in general. This is my first bike. When I tire my carb apart there were no washers or anything. I replaced what I had new and it fired right up. I may have a knock off kit then and not genuine parts which would explain the wrong size jets.

Where can I go about getting a new carb kit?

Title: Re: Caeb problems. Please help!
Post by cheapnewb24 on 04/12/16 at 18:35:17

The important thing is that you have jets with the right size opening, regardless of the number printed on it.

Under the main jet is a brass washer. You want to make sure that that washer is still there. Don't want to lose it.

Furthermore, you might be able to replace the main while the carb is on the bike if you're careful and know what you're doing.

First, get a screwdriver (I think they are not technically phillips, but that other one like a Phillips. I use whatever I can get hold of. Reminds me of the name of that movie with Clint Eastwood and the orangutan Any Which Way You Can. ;D Anyway, get those screws out of the float bowl. The point is to be careful as you may have difficulty getting in there to get a grip on the screws. Don't strip 'em.

Don't tear the gasket, or you'll have to buy another one of those as well. Put a thin layer of petroleum jelly on the gasket so it will be easy to remove for servicing. Maneuver the bowl carefully away without damaging the float. It may take a little moving around to get it off and on again.

I don't think you'll have to remove the float for this. Take a good flathead screwdriver of an appropriate size and get it in there securely to remove the jet. It's brass, which is soft, so you don't want to risk stripping it. Again, make sure you get the brass washer and make sure you put it back on the new jet.

Here's the tricky part. I tried and failed at this frustratingly. It took awhile to figure out what happened. The first challenge you will have is threading up the new jet without dropping it into oblivion several times Not cool! Secondly, and perhaps most importantly, be very delicate when threading in the new jet, for the main jet actually threads directly into the needle jet ([b]not the carb itself) This needle jet is moveable and slotted. There is a little nub or pin over which it's slot aligns. If you are not very delicate here, you will push the needle jet past past where it can catch the threads of the main jet, and then you will inadvertently turn the needle jet past its proper alignment. [/b] This means you'll likely end up removing the carb to get everything back together.

If you don't know what's going on, you may end up trying painfully for hours to thread that thing up in there, but it'll never take. :(

Understand? Clear as mud? ;)

K&L makes a good carb kit which is fairly well received. It is the one I have used. It is #18-5064, and it is readily available on EBay and Amazon for around 16 bucks or so. I have not needed to use all of it. I reused my old float valve; even though it is boogered up, it still works. ;)

You may not necessarily need a carb kit. You need what you need. :-? Jets are not even included in this carb kit.

Go to the section in this forum labeled Marketplace. In it you'll find Jet sets sold by Lancer who is a member here. He puts together and sells the sets and other items as well. Many of us have bought his jet sets including me. He also provides tips on which jets to use. My forum signature notes my current jetting but I do use a Harley Dyna muffler which is slightly more free flowing than the stock muffler. It sounds as if you probably have an adequate collection of jets already, maybe it is just a matter of selecting the right sizes.

Also, go the tech section of the forum, there is an index of the contents. You'll find a thread concerning the "white spacer mod" for the carb which is worth doing if you have it apart. Good luck.

I'm becoming more familiar with this bike as I've torn the tank off more times than I can count. I've removed the jets a few times now to clean them out without removing the carb. 8-) thanks for the advice. I'll check into the jet kits

Title: Re: Caeb problems. Please help!
Post by cheapnewb24 on 04/12/16 at 19:18:31

To understand how the jets interact (how the carb basically works)...

The upper portion of the carb consists of cylindrical slide with a spring-loaded needle at the bottom which is controlled by a vacuum-actuated diaphragm. I am a little fuzzy right now as to how it exactly works, but, basically, the cylinder blocks the carb body and acts as a second throttle plate (or perhaps even a venturi :-/). Anyway, when the throttle is opened, the slide lifts with its needle, the slide allowing in more air, and the needle allowing in more gas.

Remember I said that the main jet is threaded up into the needle jet? The fuel comes up through the main jet, then has to deal with the needle jet, The needle rests down into the needle jet. The needle acts as a fuel restrictor. When the needle is lifted to its maximum, the main jet is the main fuel bottleneck.

The main is supposed to make the most difference at full throttle.

The needle jet (needle position is what we're concerned about here) makes difference off idle and part throttle. Richening that up a bit (compared to stock) will help response.

The idle jet (the only quickly adjustable one) makes the most difference-- DUH!-- at idle. :D Adjust this one as follows: With idle speed reasonable, turn counterclockwise to richen, clockwise to lean, if I am not mistaken. Aim for the midpoint position where the idle speed is the greatest for the same idle speed (throttle plate position). Very easily understood hands on. Set the idle speed adjustment (you know, that little spring-loaded fingerscrew on the throttle cable cam thingy. :D) Then, turn the idle screw one way till it speeds up and runs best, but keep going until you've gone a little too far. Go until it slows down slightly. Stop, then go the other way until it reaches its sweet spot, then passes it and slows down slightly Then go back halfway. This should be the sweet spot for those conditions. Remember that this should be done after driving the bike and getting it nice and warm. In summary, the idle mixture should give the highest idle speed for the least amount of throttle (or the highest vacuum, as some would say).

Now, you're brain is fried, and you're still wondering about the spacer mod? It works like this. There is a white plastic spacer on that spring-loaded slide needle which pushes it down into the needle jet. Shaving down this spacer (plastic washer) or replacing it with a thinner equivalent of #4 washers will allow the needle to lift up a bit and allow more fuel in at part throttle. This is accessible from the top of the carb. Lift the diaphragm slide out. Note that the screws on the cover could be difficult to remove. Do not strip them! Way down there in the slide are two little screws which hold a plate. Remove these, and you'll find the spring and needle with it's white spacer. Here's where you can replace the white spacer with washers or grind down the spacer. A magnetic screwdriver will be helpful here to get the screws back into place. The plate, spring, spacer and everything goes on a certain way. I think there's a little metal washer in there as well below the stationary e-clip that the spacer rests on or something like that. You'll know what I'm talking about when you get it apart. ;)

Got it? ;)

I don't think you usually buy them as kits. If someone has prepared them into kits, they tend to be expensive. Find someone on EBay that sells Mikuni jets for cheap, buy a bunch, and combine shipping.

You may be able to do the spacer mod without removing the carb as well if I'm not mistaken. You'll need to remove the tank, though, I believe.

By the way, it may be helpful to count the turns on your idle mixture needle. 1.5 turns out from bottom is ideal, and 3 turns out is the upper limit for that jet. Richer than that will need a bigger jet.

Niche Cycle Supply on EBay is where I got my main jets. It took a little while for them to arrive, but that may have been a fluke with the trucking. Anyway, they seemed to be a good deal.

Good point! When you bottom the idle screw, be very gentle. Don't torque it. Just go far enough to see about where it bottoms. Then count the turns back.

And, regarding carb kits, I gather these things aren't like those old Briggs & Stratton flatheads with the Pulsa-Jet carbs that needed rebuilding every 5 minutes. ;D Better keep a hundred fresh fuel pump diaphragms for those old things, right?! ;D

Probably the most vulnerable parts are the bowl gasket and the float valve, I would guess. On the other hand, I boogered my float valve, and it still works! ;D

The general attitude about carbs around here is to clean it up, replace what's broke and don't worry about it. Am I right? ;)

Post by cheapnewb24 on 04/12/16 at 19:56:23

In my experience, the clutch will slip before the tire does. ;D

Not saying you can't do a burnout, though, especially if you hold the front brake. I think I've slipped the tire on concrete a bit and on spun some on dirt. I've had the bike kick sideways when goosing it on damp pavement, only after the clutch slips a while. ::) Honestly, though, I don't have much experience with slipping my tires. It's not something that the Savage does so easily. I've never even popped a wheelie that I know of on a motorcycle, least of all on my Savage. Burnouts on motorcycles can be rather hazardous, as they can quickly cause highsides and lowsides I would say.

However, there's a huge difference between what these guys are doing and actually burning rubber off the line from acceleration. When you actually sit your weight on the bike and don't hold the front brake, the weight shifts to the rear and causes the rear tire to grip HARD. Takes quite a bit for it to break loose. Ain't that right, Justin?

That doesn't even include balancing issues. You have to go from holding the bike with your feet to suddenly having your feet on the pegs applying sudden maximum acceleration and torque to the rear tire. A recipe for finding your face on the pavement.

Tricky stuff that takes skill. Ain't that right?

I am replying to the original post. A bike that won't run right when you open it up usually just neede a carb cleaning. The main jet is usually clogged and a good sonic cleaning works wonders. Running in all directions at once and paying your way out of a problem doesn't work as well as slow, deliberate action. Ask folks on here what to do before you do it. Don't tell them what you did after the fact. This is in answer to the FIRST poster. ;)

Pilot at 52.5
Needle is in middle groove out of three
Main pilot air jet at 230
Secondary air her at 70
New mac performance muffler with baffles
Seems to be still overloading no matter where adjustment screw is. Took it for a ride and it won't rev up and can't break 45 mph. Accelerator pump and top rubber doo hicki is in good shape and petcock looks good. Ran on prime with no difference. Starting to irritate me so much I'm bout to take it to shop.

Those numbers don't sound right. I don't think the stock carb has an accelerator pump either. Are you talking about the silide? The-big-rubber-diaphragm-topped-cylinder-needle-thingy?

Not sure about the air jets, but we don't normally use 130 main jets for the Savage. You sure you didn't misread it? Did your bike come out of California? What is your location in the world??? The pilot jet is right for regular US models though. :-/

Yep...

You might get it fixed.... And you also might have a stroke from the mechanic's bill... >:( and you then might use what's left of your brain to set fire to your bike... >:(

...then, finally, topping it off with a self-inflicted gunshot wound to finish the job. >:(

Don't jump off the deep end. Everything is going to be fine. ;) Calm down. Take it easy. This stuff can be tough, but, from what I gather, a Savage is ridiculously easy to repair compared to other bikes. The stock carb, in my experience, works great. Do the fuel flow test. open the float bowl and see how fast the gas drains out. Simple as that. Once you know that, you'll then be able to reduce the number of possible causes. If you feel you need a carb kit, which, unless I'm mistaken consists merely of a couple o-rings, a float valve, and a float bowl gasket, you can get K&L kit 18-5064 off EBay for around 16 bucks.[b] Now, that's no guarantee it'll fix anything. Unless the problem has to do with those 2 little o-rings (possible, don't know, but I doubt it) or the float bowl gasket is leaking (inconvenience, not applicable), the only thing that is likely to cause you a problem is the float valve. It can stick open or shut or fail to seal properly. This means you will have either flooding or starvation, and it can be intermittent. If it's not the float valve, buying a kit won't do a darn thing. On the other hand.... it might do something. :-/ You just won't know until you try it, and it either helps or it doesn't. The dealership will do the same, and they'll charge you for labor.

Listen to Justin. Take it easy. Let it go. You can't ride your bike right now. Even if you took it to the shop, chances are, if they have to install any parts, there's a high risk they'll have to be ordered, which will take time. [b]If you want to take the easy way out and hire it done, that's fine as long as you're going to be happy with the consequences. ;) You won't learn, and you'll blow money. Running to the dealer won't help you. You'll get your best support here, both technically and emotionally. Dealerships seem to lack both somehow. :-?
Take this opportunity to learn how to fix your bike and potentially save a lot of money. One shop (not dealer) I talked to charges $75 per hour for labor. If you're not careful, you can dump as much as the bike's worth in repair costs. Worse than that, you'll be dependent upon the costly assistance of the mechanic. The more you work on your bike, the better prepared you will be to work on it. ;) You'll have the satisfaction that comes with accomplishment and learning, and you'll save money. Burning money on the bike is liable to drain your pockets and your morale.

Working on your bike as a newbie can be a tough job, full of frustration. Are you ready? 8-)

So, your initial post, when you suggest that the problem only occurs when you grab a handful of throttle, along with my understanding that your main jet is small combined with a performance exhaust, makes me suspect your main jet is simply too small. However, you are also saying that you need to use the choke on top of that and that you can't get past 45 mph. That seems way too slow for a main jet issue. :-?

There is something you need to know. That slide (big cylinder thingy) needs to stay very clean. If there is the slightest substance on it to make it sticky, the bike will act crazy. Also, a vacuum leak will cause problems.

If nothing else, take the carburetor apart and clean it thoroughly. And I mean take it off... take it all off. :D

Post by cheapnewb24 on 04/15/16 at 22:54:33

As far as jets for a straight pipe... Genuine Mikuni 155 is a good one. Go no smaller than 150. 152.5 is in between. You can go as high as 160 supposedly, but 155 is usually as high as people here go. If you want to split the middle, do 152.5 If you want some choice, buy one of each size: 150, 152.5, and 155. Use whatever combination you want somewhere in that area. You don't want stock jetting (145) for a debaffled muffler or any reasonably well-performing muffler. You might want to try a 55 pilot jet as well. No guarantees it will help, but with your muffler, it might give you an improvement. You see, if the pilot is too small, your idle circuit will be too lean no matter how much you turn the screw. If it's too big, however, you'll have a hard time leaning it down without bottoming out the screw.

Now, that needle on the slide should be set to whatever setting that lifts the needle the most. Again, that's kinda funky, and I don't know whether the air jets and whatnot are what they're supposed to be, and I cannot say it will necessarily fix all the problems you've been having, but it should set you up to get it in the proper order. It may help; it may even fix it. It's very chancey, even doubful, though. Right now, who knows what's in there? :o Confusing. :-?

Here is what the stock needle is supposed to look like. Pathetic, ain't it? There is a white spacer above the e-clip. Adjusting that spacer is the "white spacer mod" everyone talks about.

Hmmm... If it's fouling the plug, isn't that a sound you're getting too much gas or too much oil? Can you lean foul a spark plug?

Rather than try to tune to the pipe, why not put one on that's easy to tune To? Get better performance, mpg, not piss off the dead, AND, nearly everyone here knows just what jets work. Tuning to an open pipe is guesswork.

The notches in the needle made me say Huhh? too..
And nobody decides a carb needs a kit faster than someone who hasn't a clue.
Even fingerprints on the slide can cause it to stick. Clean and dry, like you're handling a halogen bulb.
I doubt a shop will even try to jet it with that muffler, if it can be called a muffler.

You can get a Harley Dyna muffler off EBay for cheap. Are you really wanting to run a straight pipe?

What someone wants and what they are able to do may be slightly different things. If he just WANTS a straight pipe, but can't get it running,then at least Buy a Dyna, PROVE that the bike Will run, then swap out the pipe and jet until you get it.
Right now it's a bucket of variables. Eliminate some unknowns.

The fact that your slide needle has alternate grooves for the clip, and the odd number on the main jet - indicates that somebody has installed a Dynajet kit in this carb. Somewhere there is a conversion table to see what that that main jet converts to in a Mikuni number.

Thanks Dave, you may have found the problem.

Dynojet may have crossed my mind, but that smaller number kept confusing me. I kept thinking that maybe Dynojet would show a bigger number. :-/

I looked on EBay for slide stuff. There wasn't anything really definite, though I saw some kits with adjustable needles, I didn't quite find something definitely for the Savage. I guess I just overlooked it, simple as that.

Overlooking.... it's right there in front of you. You think of it, oh so lightly... with such subtlety, and then you go on looking and then you never really find it. Get's you every time.

Then again... :-/

http://www.jetsrus.com/FAQs/FAQ_mikuni_vs_dynojet_vs_keihin_sizes.htm

I was right; Dynojet shows bigger numbers than Mikuni. A 130 Dynojet is equivalent to a 122.5 Mikuni, which is even worse. That's leaner than California. With a straight pipe, it might just die out under a fistful of throttle, don't ya think? :-?

Or... he could buy some proper jets for a straight pipe. ::) Might be a little cheaper than a muffler. Either way may help. Regardless, If he's got a 130 main or smaller, assuming the air jets are stock, he needs a rejet anyway.

Just make sure you wear earplugs. ;) And don't make the dead (or the living) too mad at you. :D ;)

Oh, and by the way, a straight pipe will generally cause you to lose power in the most practical portion of the power curve due to exhaust reversion. Our bike isn't cammed hot enough to take advantage of much top end that might be gained (if any is gained at all) from running a straight pipe.

You'd better be looking solely for sound, 'cause that's all yer gonna get.

Here's another interesting video.

I've been learning with these two videos. :)

Not everything applies to our bikes as they're talking about Harleys. Our carb doesn't have an accelerator pump.

I set off the alarm on someone's truck once cranking up my bike with a stock muffler. ;D

You're liable to cause a public disturbance with a straight pipe. ;D

Must've been a WalMart alarm system.
