Suzuki Bandit - Troubleshooting Air/Fuel Issues Checklist

[@oembol]

I've been watching your videos about your bandit issues since 2 weeks now and I'm glad you uploaded this video just now to recap it all. Thanks for putting all the videos out there, it's been a huge help! I'm on a mission to fix my own bandit and with your help I think I might just be able to do it.

[@matttriestodothings]

Glad to hear they're of some use. I hope you get your Bandit issues resolved swiftly and get that bad boy back onto the road!

[@Belgariot]

nice info for the bandit user. One thing I must say as a bandit owner and bike has over 100tkm on the Meter. I had the similiar issues as you had, I replaced the actual needles(and all the seals needed) To the carb and installed a little bigger jetpilot and issue was solved.

[@matttriestodothings]

Awesome to hear you've gotten that much life out of your Bandit. Hope you get another 100,000km!

[@Belgariot]

@@matttriestodothings sure is running good and is reliable as New one. 👍 I love the bike becouse it just is a good motorcycle, it has a good character built In... And the sound is awsome 🤩kzbin.info/www/bejne/kGrYf6Vrd6pkj8k

[@charlesscottkelly]

This is so helpful, thanks , iam fed up with my bandit going to the bike shop and coming back as bad as it went in. Time to do it myself.

[@matttriestodothings]

It can be both frustrating and rewarding to do it yourself. There's just a lot of different parts of the whole system that need to work in unison. As an amateur tinkerer like myself the diagnosis is often the most difficult thing to do--figure out and isolate what's actually wrong. None of the individual tasks are that difficult on their own. It's when you're unsure of what the problem is so you just start throwing solutions at potential problems that can be exceptionally frustrating. So always start with the simple things first.

[@stevenwarner7348]

Reviewing again. Thank you so much for this. Got the NIghthawk running yesterday. The "Little Bandit" is on hold and a fuel tank/petcock overhaul that I'm not in the mood for right now. So the cb750 is a "choke only " run at this point. It has been 10 years so I take that as a win. The carbs look like they haven't been touched but with on and off all day, (new oil, air filter, oil filter, new petcock, new gas with an additive boost). idle idle idle. ~ seems to run well.~~~ 4k on the tack is the best I could get with full choke and then with a half choke at 2k. So it's the carbs. I knew that. ~ Your post here is very very valuable to me ~ Thank you (again) so much for this. 👍. (Maybe I need to send you some $$$) not sure. All good. 🙏

[@matttriestodothings]

Good to hear you're making progress Steven. Sounds like you've got your hands full juggling so many projects! I can totally understand the "not in the mood for it right now" regarding certain tasks. I'm in a similar situation with a Harley Sportster I'm working on for my Dad. I've done just about everything that needs to be done. The bike fires up easily, choke is off after less than a minute, bike revs great, and then the bike gets to hot and I can watch it start to get hyper rich on the carburetor. It doesn't make any friggen sense to me. It's just kicking my ass. I'm dragging my feet on that project and just prioritizing my race bike SV 650's right now, but it's always driving me nuts a bit that I'm tons of hours into this Harley, as well as $1400 in parts and labor (I wasn't changing OEM tubed tires myself on spoked wheels, hence the labor). It feels like it's sooo close but yet so far if I can't figure out what's causing me to go hyper rich only once the bike goes hot. So it sounds like both of us have some more carburetor fiddling, tuning, and testing time in our futures. That's alright. Gotta look at the little wins and remember progress is progress. It can be super overwhelming taking the 30,000ft above view and seeing the mountain to climb. Thanks for the update man.

[@agentofnecessity]

Amazing vid, lays out a bunch of wrenching that I'm looking forward to learning as i work on my own bike in the future. Delivered at redline pace too 😂

[@matttriestodothings]

Good luck on the wrenching! Focus on the simple and easy things first. That's a lesson I learned the hard way, hah.

[@yveslegrand9826]

I absolutely agree about the PAIR stuff. All the rest is also making lot of sense! As far as the TPS it MAY change a bit the ignition timing. Openning throttle means higher intake pressure and this requires a later ignition time. However, as all electronics devices, the builders suppose we are to dumb to understand and provides not information on how it works and no tool to adjust.

[@matttriestodothings]

I'm of the mind that the TPS doesn't do anything. I'm leaning more and more that way. I have come across absolutely no mention of it on any of the racing discussion on SV650 forums--and those people will get into detail on anything and everything that could give an advantage. And the superbike builds will remove the stock carburetor completely and drop in Keihin FCR flatslides. I really should have tried unplugging it on the Bandit when I had it.

[@yveslegrand9826]

I had this stuff on a 2005 Suzuki GS500, removing it is easy and causes no harm. I also disconnected the carbs pilot tubes. Both are just for emission testing. What they do is lean the mix when shutting the throttle off and sending air in the exhaust. Nothing useful for the bike performance nor the environment....

[@volymard]

Thanks for this video very useful and informative. I'm currently wrestling the low end rpm on a stage three intake/exhaust runs fine past 3G, it's got #155 mains but runs shite below

[@matttriestodothings]

Honestly, similar type of issue that I fought with my dad's 1990 EX500. It had a dyno kit in it with bigger mains and (unfortunately) they had already drilled the slide holes out, so I was stuck trying to make the dyno kit work as opposed to stock tuning. Does it get better as the engine heats up? I've found that a lot of the sluggishness goes away once the engine is hot. Not like idle it for 10 minutes hot--I mean go run it on the street for 15 minutes hot. I wish I could tune that out.

[@nitramh24]

That’s awesome! I did most of those steps on my Kawasaki 98 ZX9R. You should get the Japanese screwdrivers to avoid stripping out the screws. I only had to buy new float bowl rubber gaskets for the carbs and replace a few of the rubber pipes and hoses. The bike is good as new. Fyi, I removed the tps by accident, and have been running without it for four years. The bike is a tad rough at low rpm, and a bit hotter around town. But once above 3-4000 rpm, I notice absolutely no difference👍

[@matttriestodothings]

Can't remember if I mentioned it in this video--yea, definitely use a set of JIS screwdrivers to avoid a lot of frustration. I have a set of Vessel drivers I keep at home and travel with a more portable set of JIS screwdrivers at the track. My experience on replacing rubbers is similar to yours. Float bowl gaskets, the tiny oring on the A/F mix screw, and fuel pipe orings are usually all that needs to be replaced assuming that the jets haven't been destroyed previously.

I am now a subscriber. This video I will be very very close to. Review Review Review. And I think I've made the decision to move the bike into the kitchen. Yep. Gonna work on it there. But then Alas, it's Springtime for me here in New Hampshire. So many other projects. My 02 Bandit GSF 650 EXACTLY like yours. And so I guess I'll start with a new battery. Whoop Whoop Whoop!!!

[@rticDriver]

HI, The throttle censor works by cutting engine of like a switch when trying to pull away if side stand is still down , its there to save lives. Done it a couple of times on my gsf600 2002 Bandit.

[@matttriestodothings]

There's a separate switch for the kickstand (kickstand switch). For sure those come in handy since I've once drove away on a bike without one and found out it was still down on a left hand corner, hah. But I'm talking about the Throttle Position Sensor (TPS) that's connected to the carburetor and has arguable effect on fueling.

[@ROOSTY_EMX5]

Thanks for the information love the channel full of cool bikes n great tips! Btw think of the tps like a maf + fuel flow for the engines ignition timing, Why they call it a throttle pos sensors made me scratch my head 😂

[@matttriestodothings]

Absolutely man--hopefully some of them are useful. I've spent way too much of my life worrying about that damn TPS... haha.

[@BanditK]

Don't have to take my tips but if you really want to get the most out of a bandit start with a holeshot kit, then afterwards follow up with a sync and colortune the idle mix. Run it this way for a week or so before doing valves and repeating the sync and colortune once more. ( unless the valves are noisy from the get go leave em be)

[@matttriestodothings]

The bike runs well enough now that this is about all I'll ever do to it. It's reliable, starts right away, warms up a lot quicker than it used to, doesn't foul plugs, and I'm not afraid that it'll leave me stranded. But you're right--you could definitely go a lot further towards further fine tuning this bike.

[@juans3728]

Get a set of cv carbs from a bike with more power, i struggled with a 550 Zephyr unil i mounted a set of mikuni 32 cv from a us 86 gsxr 750 they worked perfectly and engine gained at least 10 hp and rewed 1500 rpm higher, carbs from a 100hp bike on a 50 hp bike with no other mods than turn outside manifolds upside down for different spacing, had to connect carbs to stock 550 filterbox 😅

[@matttriestodothings]

Could be. The Mikuni's in my SV650 are awesome. I never fought with a carburetor more than I did with this Bandit.

[@OccultEngineering]

The fishing line tip was genius. Subbed. I just got my b12 running right, but have a tranny issue. Having trouble finding any in depth reading material beyond exploded view diagrams on the shift cam assy. I can shift into 2nd, and back into neutral... but have no other gears. I can roll the shift cam over manually with the oilpan off and engagement is the picture of perfection. The shift pawl on the shaft has perfect engagement with the shift cam gear. It rotates the gear but does not engage the cam itself. Trying to get an idea of what I'm likely dealing with prior to pulling the clutch basket if at all possible... Any ideas?

[@matttriestodothings]

Oh I got the fishing line trick from someone else--though the better line would be a guitar string. I wish I could be of some use on the transmission issues you're having--I just don't have any experience with them. My SV650 is way harder shifting than either my GSF6 or DL650, so I think there's something wrong with it, and I was planning to change the shift star. But your issue sounds way different than that. I see that you recently posted a video saying the shift issues you have may be "Fixed!". I'm at work, but i'll mark it for when I get home to watch.

[@OccultEngineering]

@@matttriestodothings I figured out the issue. Shifter pawl was off center 2 teeth with the shift cam engagement gear. Recentered it and now I have all gears. As soon as the sun finishes burning off all the morning dew I'm heading back up to Blood Mountain!! I would discourage using steel guitar string as it will gall the aluminum carb bodies. The slightest scratch in those tiny venturi tubes can cause turbulence issues that will drive one mad trying to sort out.

[@EpicAdamMotovlogs]

Great informative video. Any issues I've had on my 96 Bandit have been fixed by either changing the spark plugs or changing the battery. I always start with the simplest things. I remember one issue I had where it would try to start then backfire and stop running. I changed all the spark plugs, filters etc & I think it was as simple as I accidentally swapped 2 ht leads over 😅 because after I changed the spark plugs I noticed I was putting the 3rd ht lead onto the 4th plug and I wondered if I previously done that. I just put on a mint condition tank and plastics. My petcock and rubber hoses could do with being replaced. I didn't even think about replacing the hoses until I saw this video

[@matttriestodothings]

For sure man. My brain always jumped to the most complicated solutions when really it makes things so much simpler to rule out the easy things first. I have done a similar thing with the backfire on a different bike! Honda CL350--had the points hooked up backwards and was firing out of phase. Just shot some flames backwards through the carburetor, hah. I just replace vacuum lines all the time because I bought a roll of like 50' of the stuff a few years ago and I'm on a mission to use it all before I die. Not sure if I'll be able to. I replaced the short fuel line just because it gets stiff and I used to be taking the tank off/on so often it made it easier to manipulate. Ahhh so you got the new fancy bits put on? Looking forward to seeing how it looks!

The tps does very little to the ignition curve and it's a completely un noticeable difference. Off idle and cruise is affected. Obviously cause main and idle are pretty much decided for you, by the bike.

[@matttriestodothings]

Gotcha--thanks for the explanation. I've been meaning to just unplug the thing someday and see if I can even feel the difference. Now I at least know where to look.

Thanks for the vid. Did you have a chance to compare the stock windshield with the aftermarket as far as wind noise goes? If so much improvement? Cheers,

[@matttriestodothings]

Wind noise, I really couldn't tell you. The only time I ever rode the bike in full fairing was well over 5 years (maybe 8, lol) ago when I rode it home for my friend when he bought it. I can tell you that the little fairing does give some wind relief by taking it away from your chest. I prefer riding it with the small windshield vs without it.

Hey Matt, just watched your video on the Intercepter 500 carb rebuild. Awesome video. Would you consider doing mine for an Intercepter 1000 I just bought that's been sitting for 15 years?. I know my limitations fir stuff like that.

[@matttriestodothings]

Are you in the states? I don't think I'd be comfortable working on somebody else's equipment given my limited experience; however, I absolutely have a recommendation on somebody that will do a fantastic job. There is a guy by the name of "squirrelman" on the vfrworld.com forums that has probably rebuilt hundreds of carburetors ranging from the 500, 750, 1000 and every permutation between. I've recommended him to people before, and I haven't heard a bad word about it yet. He's active on those boards constantly (I can see he's actively chatting, lol). The advantage to using somebody like that is that he will know right away if something is amiss or wrong. Say like a missing thrust spring/washer. I don't have the experience yet to just sense when something is missing. But I'm certain he has a box of spares and probably near 40 years of handling the carburetors to know exactly what needs to be done. If you want me to reach out to him to get contact information, let me know. Additionally, if this is a new bike for you, I'd absolutely recommend signing up at vfrworld.com and starting a thread in the Intro forums and then the 1st/2nd gen forums asking any questions you have. The VFRWorld forums are, BAR NONE, the most helpful motorcycle-specific forums in the world. I am constantly on different bike boards, but nothing compares to the knowledge of the collective on the vfrworld forums. Especially the older generations. I constantly feel like I owe somebody money for the amount of knowledge I get from reading those discussions.

I've got the same bike but my issue is the vacuum system, the plunger in the petcock isn't getting any suction from the carb, hence no gas going anywhere, any tips?

[@matttriestodothings]

I shot some video I haven't edited yet... but I just replaced mine with a standard petcock from a Yamaha. No more vacuum. But besides that, there are three things to try of varying difficulty and cost: 1. Replace the vacuum line. Maybe it's got a small tear/fray. 2. Take apart them vac-petcock and clean it. 3. Rebuild it If I'm taking it apart already, I'm rebuilding it with new. I did this myself and it lasted a few years--but it still ended up failing. which is why I just replaced it with a manual one.

[@jacknicolson2597]

What does gapping the spark plugs mean? I’m also troubleshooting trying to get the elusive 4th cylinder working

[@matttriestodothings]

So spark plugs have a gap between the electrode and the ground. That gap can be modified by bending the ground. Spark plugs usually wear with time, and the gap increases. If it has increased too far, you'll have too weak of a spark or misfires. If they have come together, you may have too small of a spark. Usually the spark plugs come fairly close from factory, but bikes specify different gaps dedending on the manufacturer. It's usually not the difference between a bike running or not, but you still want to know you're within tolerance. If it's way off, you've got problems.

[@jacknicolson2597]

I shall investigate that then also, thanks for getting back so fast, your videos have helped a lot in the last week, bike is running smoother just that one temperamental cylinder/carb but I’ll get there. Big up from Scotland 👍

[@matttriestodothings]

@@jacknicolson2597 You'll get there for sure. The other thing you'll want to be certain of is that your Air/Fuel mixture screws are all in spec and where you want them to be. I was recently following a thread for several months where a quite bright guy (sincerely) was struggling mightily with a 90s GSXR carburetor. He'd done everything including buying a secondary carburetor to troubleshoot the primary trying to figure out why one single cylinder kept on giving out. Went on for months. Finally a single post basically saying "Re-did the air/fuel mixture screws, and everything is perfect" finished the thing off. So, do the simple things first, and then start brainstorming the tricky bits. You're on the right path by checking spark plugs right away. I spent many many months chasing running problems just assuming my air filter was clean. Swapping in a new one made things so much better. Good luck. And cheers from the midwest US.

[@mariuszmeyer6711]

Hi there I've got a question, perhaps you can help me. My bandit 1200 started cutting out so I thought maybe the spark plags needed to be changed so I changed them. They were very dirty. For the first 10 miles no problem but after that it started cutting out again. Mechanic told me that could be the coils so I changed them but still is cutting out. When I open the throttle the bike goes but eventually cuts out completely. What do you think that could be? Do you think that could be carburettors? If so what should I do? Thank you for help

[@matttriestodothings]

It could be the coils as they heat up, but I would suspect your pulling dirt into the carburetors--especially if you tried swapping them and the issue persists. If you have an inline fuel filter, I would check and/or replace it. If you have rust in your fuel tank, you're fighting an uphill battle until that's resolved.

[@UA10i12]

I have a 1998 SUZUKI GSF 600. It was parked for a long time, I am not sure how long thought. It had a rusted tank and the fuel valve was rusted through. I replaced the fuel tank and valve. I put in fresh fuel, cleaned the carbs and replaced some parts, like floats, (my first time messing with carbs). It won't start unless I use starter fluid. It starts and revs high with starter fluid and then dies, unless I keep spraying starter fluid. I followed guides on adjusting floats and adjuster screw. I'm pretty sure I got the floats correct, but I am not 100% sure about the adjuster screw, I tried messing with it but no change. I opened drain plugs on each of the 4 carburetors to make sure that the carbs are getting fuel in the first place, and they are. I am not sure how to proceed. Can anyone help?

[@matttriestodothings]

Before we go any further-- you mentioned that it "had" a rusty tank. Did you replace the fuel tank or de-rust the current one? Rust in the fuel tank is going to make its way into the carburetors one way or the other--especially if you don't have an inline filter (which I never got to work due to the lack of space on the mk2).

I have issues with throthle response mainly downlow under 4,5k rpm. is that normal for a bandit lol? my SRAD has a lot more agressive response.

[@matttriestodothings]

Is it actual throttle response (how quickly revs responds to throttle input) or is it issues with power delivery (weak) at low rpms? I've found the Bandit to be rather lazy compared to other inline 4's of the time period I've ridden. It's not a bike you're going to accidently lift a wheel on. I've got my throttle response pretty quick but the actual power delivery takes longer to come on than I'd expect. The Bandit is also heavy as hell. It's nearly 90lbs heavier than an SV650. Your SRAD also has at least 50HP more and weights 50lb less than the Bandit (assuming you have a 600).

[@lulhoofd2]

@@matttriestodothings yeah lazy would be a better description tbh. But sometimes it feels like it kinda bogs and then picks up. But only under 5k rpm really. edit i hvae a srad 600. it probably is a mix of a lazy engine and bogging down a bit. guess I'll have to take a look at the carbs.

It would be cheaper and easier to convert it to fuel injection by selling your carbureted Bandit and buying a fuel injected bike.

[@nihonkokusai]

@@matttriestodothings wtf

[@matttriestodothings]

@@nihonkokusai hah, I'm being blunt but I'm not lying. I don't know if I could do it if you gave me $2k and a year. It's a fairly common question for sv650s and the common advice is to trade it for a fuel injected one.

[@nihonkokusai]

@@matttriestodothings is the old engine fuel injected possible if I get another ported injected and wiring ecu etc?

[@matttriestodothings]

@@nihonkokusai I have no idea if the 650's injectors line up with the 600's intake manifolds (or if there's a plug and play solution). I really doubt there's an easy solution. I'd assume someone that could do it would need to have pretty intimate knowledge of both the source bike and the destination bike. I've watched some videos of people attempting similar projects. This guy is currently doing one on a VF500F Honda. He's a hell of a lot smarter than me; however, there hasn't been any updates in a while so I'm wondering if he's hit a road block. kzbin.info/www/bejne/oWekhpWkadZ_bNk Truth is I don't know enough about fuel injection to even give you an educated guess at what's all involved. I just know it's not something that I would be able to take on without serious resources, time, and (ideally) connections to people that have done it before.

wow what a basement

[@matttriestodothings]

Thanks Go Jira. That was last winter's project--diamond grinding and epoxying the floors as well as painting all the walls. Took a few months shifting everything around, but I think it was worth it. Doesn't look so much like a damp dungeon anymore.

[@cynthiaowings8301]

anyone know why a Suzuki bandit 600 would only rev to 6000 rpms

[@matttriestodothings]

I had an issue with an EX500 recently where it was perfect up to 7000rpm then starved out. Vac petcock wasn't delivering enough fuel. Swapped to manual on/off and problem solved. You could test this by truing to run the Bandit on PRIME instead of ON which would be the same thing. If that's not the issue, 6000rpm is when the needle valve should really be kicking in vs the pilot circuit and the slides may not be lifting properly or one or more of your main jets may have something blocking the orifice.

Wake me up.👍🇬🇧

Tps turn clockwise to advance timimg, and more fuel,counter clock to retard,less fuel, 4.5 about right

[@grabir01]

From my understanding, the TPS adjusts the timing. Very important function. Here is the only video I have found that shows calibration. Hope this helps. kzbin.info/www/bejne/oZqXp4Ktrplnnpo&ab_channel=TheEmeraldBandit

[@matttriestodothings]

How does it adjust the timing though? I know how to calibrate and adjust it--I just don't think it does anything. In fact I'm almost certain it doesn't. The SV650 uses the same TPS sensor and when people fit Keihin flatslide carbs to superbike builds, they don't retain the TPS. I've seen that video and I'm not really convinced the TPS adjustment was responsible for the changes in riding behavior.

[@grabir01]

@@matttriestodothings TP and engine RPM determines spark advance. Not saying that is an axiom, but it would be how I would engineer it.

[@matttriestodothings]

@@grabir01 yea, I get that. But the way this one specifically is setup is (my understanding) is to make a tiny adjustment during constant throttle conditions to slightly improve mpg--it has no discernable change on how most people ride them. Which is why they're mostly just disgarded by a lot of people that know these bikes really well. I wish I still had the bike to test it. It's much harder to get at my sv650 tps connector and unfortunately that bike is track only now.

[@grabir01]

@@matttriestodothings That would be interesting to know on a dyno to look at the graph with and with out. Now that you mention it, it actually sounds plausible that it is to lower emissions=mpg improvement on a test loop. Right now I have mine plugged in and using it. Just bought my 1200s a few days ago. Been wanting one for years. As of now, this bike delivers the mail!! Runs superb!! Also. Love your garage!! Love it!!

[@matttriestodothings]

@@grabir01 fantastic--congrats on the purchase. I would love to know what riding a 1200 is like. I gotta imagine it's all the fun of a 600 and double the smiles when you crack the throttle. Hope you and your bike have a lot of fun miles in front of ya!

[@marksaunderson3042]

My problems were bacteria. Yes, bugs. One carb bowl was full of blue/green goo. Water + the ethanol in modern fuel = bacteria heaven. 🌳 The other 3 were a bit slimy.. No wonder it kept flooding, the float could not float, it was covered in shit.

[@matttriestodothings]

Damn, really? what kind of extremophile organism was able to live in a gasoline/ethanol environment? Or maybe it had just become a water environment by that point. Yea, that'd explain why the valve wasn't closing though, hah

[@marksaunderson3042]

It’s a real thing. The carbs had probably not been opened since the day they left the factory in 1998. 26 years later… Hydrocarbons occur naturally in nature. Bacteria have evolved that can live in/on them. Bacteria are eating the wreck of the titanic..

[@khaledkaissar5263]

It's good bike to buy it?

[@matttriestodothings]

That depends. If you're buying one that has a good running engine--then I think you're fine. I think most people would enjoy a Bandit. It's super fun and comfortable, and it has a good personality. It can be a bit of a bitch though if you're having to troubleshoot some kind of aftermarket air/fuel mess someone else started and is trying to pass off to another buyer though.

[@ArmyOfThree1000]

I wish I saw this before I got mine probably would have not gotten it and looked around more

[@matttriestodothings]

@@ArmyOfThree1000 yea, I'd say a test ride is more important on this bike than any other I've experienced. Once it's setup right, there is nothing to worry about so long as it gets regular basic maintenance. It's when people let them fall out of order for years that you run into these finicky and annoying situations. There are other bikes that are less stubborn.

[@ArmyOfThree1000]

@@matttriestodothings yeah I’m now working on it with no garage and little tools it ran before then I had to take a break on working on it and now I started working on it again and now it backfires but won’t start and I have a kit to rebuild the carbs since I know they were getting clogged and now I’m going to clean the tank as best I can and see if I can get it running but I got the bike from a trade so I didn’t really know what I was getting myself into

Piece of shit carburetors 💩🦣 I have to perfect motors for sale cheap
