Motorcycle Stalls when Clutch Released - how to fix

[@popsxbox]

Thank you! I have a 2005 Vulcan VN 800 A all original stock bike. Just started having this problem. Followed your video process and boom there lied the problem. I have a Jack so I used it to hold the bike up and cleaned the part, it was stuck as well, so after all that and reinstall the bike works as it should. Thanks again! Safe rides to all from Texas!

[@ryanbowman8708]

Oh man, thank you so much! I was checking oil, checking clutch plates..scratching my head...and the darn stand just wasn't all the way up..my friend, i appreciate your knowledge and that you shared it with the public..thank you

[@postedinthecut1565]

same thing just happened to me , glad I found this video lol

[@OzonoOzono]

I can’t thank you enough for this video, I’m a beginner biker so I had this stalling problem, I thought it was just the lack of practice but then when a friend tried to help and explain me how to do it he notice that the bike died if no gas was pumped while releasing the clutch and told me that was a problem, (he’s not a mechanic though) we ‘been checking the internet for two or three days searching for tutorials and after we saw this and try it on the bike everything works like a charm, I can finally ride in a way I fell safe and confident, no more drag race starts nor stalling

[@guttagutta420]

Drag race starts 😂😂😂😂😂 Same here brother, same here. New rider and having this exact same issue. If I don't give it at least a 1/8 inch turn on the throttle it stalls as clutch is being release. Can't wait to try this in the morning.

[@fromthebackseat4865]

Great video man, I'm ashamed to admit I spent the last two days scratching my head at this problem. Ended up completely rebuilding my carbs before I found your video and solved the problem. Thanks a lot!

[@Crouton_6]

I ordered a whole new carb because of it.. 😪

[@aragotoblythe]

This was the exact problem with my bike. Cleaned my switch off with some alcohol, threw some oil on it, problem gone. Thanks Spelunkerd!

[@politicalprisoner6632]

Yes, I was inspecting the kickstand switch as suggested, and I cut the wire leading to the switch determined to bypass it and move on. As I did this about half a cup of thick muddy liquid oosed out, nice. No wonder it didn't work. Ok, rewired a connector bypassed the switch and got back on the road. Thanks for the love, jack.

You're welcome, I feel the same way.

[@MrFunster125]

Thank-you! Adding in the ground wiring diagram really made a difference for me to help understand what's going on

[@spelunkerd]

Today I received a question posed through Google plus about the adapter I used to tie into the circuit in this video. I'll record my response here in case anybody else is wondering. Hi, Joshua. I don't often use Google plus, I hope this reply gets to you. The leads you were talking about were part of the Lisle 69200 kit, a bare bones adapter kit for a common terminal. You can find it on Amazon if you want that one. Lisle sell others that are more complete, Lisle 69600 is a little better. The one I'd really like to have, one used by Scannerdanner and Eric O is made by AES Wave, titled uTest Advanced Terminal Test Kit, AES Wave part number 16-200. However I don't have the cash to buy that one, it is far more complete with a few hundred male and female connectors of various sizes. All of them try to meet the goal of attaching to a disconnected connector, and you want a pretty good match if you are probing the female end of those connectors because if you spread the female connector it may not give good contact after that. You noticed that I attached to the male end of the connector piece, which is at lower risk for damaging the connector. The other way to do this is to backprobe with a needle or pin into the rear of the connector, and the two advantages of that are you are less likely to damage it and also you can leave the connector hooked up. PICO make a universal breakout lead kit that has a female end, a male end, and a third end to attach a scope so you can bridge the whole connector while it is in use and measure current, voltage, waveforms, etc. However all of those are pretty expensive and there is usually a work around using a simple back probe T-pin for what you want. Thanks for visiting!

[@elcheapo5302]

Always a great vid. This procedure applies to many similar switches...door jamb, parking brake, brake light, etc. Thanks for sharing!

[@spelunkerd]

Yeah, absolutely. The best technicians make these kind of diagnostic tasks look very simple, which they often are. However I don't envy how those guys have to constantly work against the clock. Probably a seasoned tech would have just sprayed down the switch with lubricant, although it might have taken a while to get it moving in that awkward position. It takes longer to do the diagnostics accurately although I find the real reward is the insight from learning how that ignition ground system works. Insight like that makes future problem solving so much easier.

[@spelunkerd]

When you put a timing belt on an engine, some manufacturers provide a little key to hold the belt tensioner closed until the device is mounted. Once the belt tensioner is bolted into place with the belt in line, it's easy to pull the key (or drill bit, allen wrench) and the tensioner springs into action. Those tensioners can be quite tricky to bolt into place after the spring is deployed. Similarly, at the end I was trying to put the spring loaded switch into place while the bike was up on the stand. So I wrapped the switch with tape to temporarily close the switch, which allowed me to more easily bolt it into place. Then I cut the tape away to allow the spring to release, after which I torqued the screws down. In retrospect It might have been easier to do that with the bike on my lift, so I could fully extend the switch while mounting it. In the end the repair worked out fine.

[@stuzman52]

Nicely done Dave especially with the wiring diagram to see the grounding paths for the ignition circuit. Glad to see that it was an easy fix for you.

[@spelunkerd]

Thanks, Terry, Happy New Year!

[@carlfritz9496]

Great video. I just had this issue with my Kawasaki Vulcan 800 when the engine dies when I let out the clutch. I was baffled about why this was happening. Can't wait to try out this fix. I didn't even know that there was a side stand safety switch but it does make sense to have one.

[@billys2416]

Great video. Well done. Not that you've asked for suggestions, but a soft box or two would be all I would add to make this video even better. My 1976 DT175 does not have a side stand switch. I'll pull the clutch basket and probably get new friction plates. I think the cable is a bit stretched too. I had to stick a bolt at the bottom stay to get more play at the perch so I'll replace it with one from e-bay.

[@spelunkerd]

[@guttagutta420]

Great vid man! I'm new to bikes and just bought a used cbr 1000f. I know where my "friction zone" is so when I'm at a light and I know it's about to change, I'll find the friction zone and sure enough...if I go past it without throttle, it stalls. When I took the MSF, the bikes they gave us were nothing like that. Once you found the friction zone and got some speed, you could completely release the clutch and be fine. My bike puts and stutters and eventually stalls 😪 I thought it was maybe the chain since it was loose so I bought another one. Still having the problem. Thanks to your vid, imma try in first thing in the a.m. Wish me luck man. Let's hope this solves it.

[@guttagutta420]

So I checked and my kickstand is different. I didn't see the push plate nor the plunger. I did however see the wire connecting to the module. Any help would be appreciated. I sprayed wd-40 all over the thing tho (not the wire) so we'll see what happens.

[@spelunkerd]

One of the things that really helps is to have a dealers repair manual. For cars, there are aftermarket providers who sell access to dealer manuals for about $50/5 years. Unfortunately neither Alldata nor Mitchell seem to be interested in bikes. I bought my manual from the dealer at the time I got the bike, but a cheaper way to get one is to do a search, you may be able to find a pdf file or DVD that isn't too expensive. All that said, if your bike is similar to mine then the switch is a simple access to ground, in which case tying the two wires together cuts the kickstand switch out of the equation entirely. Your story is suspicious for something other than the kickstand switch, in which case you may notice no change in the problem when you do that. Don't forget to put it back the way you found it before moving on to look for other causes. Carb problems and vacuum leaks are really common in old bikes, that's where I'd be looking.

[@HarlemFingerboards]

Having a similar problem but mine might be more of a gas issue. Bike hates getting into first gear if it does at all, and I need the choke up half way to all the way for it to idle. Did an entire carburetor rebuild and cleaning and still can’t get it to idle properly. Still assuming it must be a jet issue but your video gave me some knowledge nonetheless!

[@pappaspence]

Thank you. about 3 seconds into the video I realized that my issue was kick stand down. I was sure I had miffed something in the last oil change and tune up.

[@RobertNicholas-k6e]

I traced out the kickstand switch up under the gas tank there's a connection there I'm going to spray that with electrical contact spray see if that might be the problem .if not look into what u suggested. If that's not it I'm putting it in the shop wensday let them deal with it thanks for the info on ground on the clutch handle I adjusted the clutch cable down below to.And bypassed the kickstand switch to..so I put what I already did back to were it was thanks appreciate the info.

[@BuFFMotO]

When you faced this issue, were you able to ride off by giving extra throttle? Im having the same issue but I can still ride off with extra gas. Also, when my kickstand is actually down, the bike shuts off as soon as it shifts into gear. Doesn't your kickstand switch work tge same way?

[@spelunkerd]

Fuel won't help a kickstand switch problem, since the mechanism is lack of ignition. The bike with a bad kickstand switch shuts off because there is no spark, regardless of fuel delivery. You're the second person to describe your bike shutting off immediately when being put into gear with kickstand already down, even with clutch pulled in. I wonder if your bikes (newer?) are wired differently, or perhaps the clutch switch isn't working the way it should. My old Vulcan will definitely continue to idle after being put into gear while the kickstand is down, as long as the clutch is being pulled in. I would start by getting a wiring diagram for your bike. I'd be looking at other issues regarding your response to throttle. Most likely it is a carb or fuel delivery issue.

[@leonarddavis9298]

Good video. I had this issue several years ago on my 2001 Vulcan Classic FI. I now have a new issue that you may have seen. My 1500 fi was having after firing "backfire". I replaced the plugs and it solved the problem. It cruises well until I pull the clutch in and throttle down to down shift and the motor quits. I have Cobra pipes and one of those fuel command modules which I have adjusted into multiple configurations. I have to pull the idle knob out about half way to keep the bike running when sitting. The bike sit for about 2 years without any extensive running. Ran it at times while sitting in the garage but very little riding. I've cleaned the throttle body openings and flaps well. Any ideas?

[@spelunkerd]

Water in stale fuel accounts for the vast majority of problems like that, so I'd start there. If that doesn't work, I'd remove and clean the carb.

[@julianbodnar3591]

How do i fix it on a atv at has no kick stand

[@spelunkerd]

It won't be the same diagnosis but the logic is similar. I'd get a wiring diagram, try to prove you are losing spark when letting clutch out, then look for what is missing. For example some ATV's have a seat pressure sensor that won't let you move if weight is off the driver's seat, etc.

[@nickwilson1476]

Those little testing connectors are great! Much better than alligator clips :)

[@spelunkerd]

Yeah, those are from a little kit made by Lisle, though they would be easy to make with a couple of female connectors, shrink wrap, solder and a bit of wire. They have covered male banana connectors that fit my multimeter leads perfectly. Thanks for watching, Nick.

[@DeiseRebel]

I’m having this issue while out riding, seems to be only after the bike of well warmed up, seems like it gets overheated in some way, when I downshift it just suddenly dies, I’ve check the power to the kick stand but I haven’t taken off the plunger to test it so I’m going to try it. As a beginner it’s fairly unnerving that to just dies when I’m downshifting coming to roundabouts. Fingers crossed it works. I’ll reply back. I’m riding Suzuki GZ125

[@spelunkerd]

That sounds like a fuel delivery problem, I'd clean the carburetor. When the throttle snaps shut, fuel delivery happens through tiny alternate passages that are easily blocked off with debris. Gumming up of the air passages also causes air turbulence that can interferes with the Bernoulli effect, necessary to draw fuel up those tiny passages.

[@DeiseRebel]

[@mrjaywalter11]

Thanks for the video brother I have a 650 and it's been dying on my when I have the clutched pulled in at a red light or a stop sign is that a clutch problem or a carb problem?

[@spelunkerd]

Carb issue, vacuum leak, bad gasoline, water in fuel. It wouldn't be the stand safety switch since the clutch handle is pulled in. As you say a clutch problem might present with a stall, but in that case the bike would try to creep forward even with clutch handle pulled in. So you should be able to identify a clutch problem because of other symptoms.

[@alopandur]

Hello Spelunkerd - Fellow BC rider here, think you gave me a right direction to look at my bike's problem... Thanks for the video. I ride BMW k1300S and it started giving me troubles when it is a really hot day, or if I catch heavy rain. As soon as the clutch is pulled the engine dies, especially in riding when I downshift from third to second, or second to first... It is not all the time but starting to do more often now... Pulling the clutch while the bike is rolling and starting the bike works, or if I am stopped starting the bike works too, but I have to be alerted all the time. Debating is it a clutch switch or the kick-stand switch... Do you mind sharing your opinion? Thanks a lot!

[@spelunkerd]

I'd be looking at other issues, especially vacuum leaks and idle control factors. Newer bikes have more complicated control and even some ability to read diagnostic codes (and maybe even get live data on a scan tool). I don't know anything about the BMWs. It would be fairly easy to test both the kick stand switch and the clutch switch by backprobing the wiring, then measure voltage drop across the switch with engine running. However given the symptoms I'd be looking elsewhere. All motorcycles are prone to vacuum leaks, which mostly cause idle issues, improved when throttle is applied. To look for a vacuum leak, I would inspect the intake manifold between the throttle buterfly and the cylinders, and spray water onto suspicious areas while the engine is running. If the engine stutters you've found a vacuum leak. A dirty carb can present with the same symptoms, so that too is worth considering.

[@alopandur]

@@spelunkerd That's awesome man, thanks a lot, that could be the next step to check. Went to my bike and checked both the clutch and the the kickstand switches and found the entire kickstand assembly, held by two bolts, was loose and freely moving shaking 5mm back/forth... And that is attached right to the stand switch !!! Of course, the stand is not moving when the bike's weight is on stand, but when the bike held up and stand retracted it was pretty obvious... I tighten it and will ride her tomorrow to see if that was the fix (if it is not raining again... 😀) THANKS A LOT!!!

[@supersonic3588]

Currently having an issue with my ZX-7R, the bike idles and starts fine, I put it in gear and put the kick stand up, when trying to pull off it cuts out exactly the same as your video. I bypassed the clutch switch and the bike runs and pulls off fine. Replaced the clutch switch and same issue. Now I’ve bought a new kick stand switch to see if that’s the issue but I’m running out of ideas. Are there any other switches that could be causing this issue? The neutral switch for example? Great quality video by the way 👍🏼

[@spelunkerd]

As tempting as it is to throw parts at the problem, a couple of minutes with a multimeter and a dealers repair manual will help verify the diagnosis before you play the swaptronics game. You can get inexpensive (~$40) PDF copies of Kawasaki bikes on their website, and in fact parts manuals are available for free download. I'd be focused on the kickstand switch, but if the switch is good then I'd look carefully at the wires and connectors for corrosion or rodent damage of wires. Trace those wires all the way back to the igniter, it wouldn't be uncommon for a lead to be broken or accidentally removed. If the problem happens when in gear, it is not the neutral switch, which should cut out when shifted into gear. The reason bypassing the clutch switch worked was because it bypasses the whole ground circuit all the time. A good clutch switch cuts out when the clutch handle is released. Looking at the wiring diagram, you can see the only pathway to ground in my bike while driving is through the kickstand switch, so I think you're on the right path to look there. Good luck!

[@supersonic3588]

spelunkerd thanks, yeah I bought a new clutch and stand switch and it didn’t work in the beginning. I must have dirty electrical connectors or something because I was wiggling a few things around and now it works fine 🤔 problem is when you are riding the bike is bouncing around so the problem will likely come round again. Thanks for the response anyway! Top man 🤙🏻

[@MOUSEBOWEN]

So I just bought a 2006 Yamaha Royal Star Tour Deluxe. So in neutral with the clutch press in will start but will die if I release the clutch OR if I put it on gear . Even with the kick stand in or out . I was thinking was the kick stand switch or the clutch switch now I don’t know. If I try to start it on 1st gear with the clutch press in won’t start only on neutral with the clutch in if I release the clutch will die . Any advices ? Thank you so much

[@spelunkerd]

I'd approach it the same way I did here. If you jump the kickstand switch with a short jumper wire the problem should go away. If it does, then fix it correctly. You'll want to get a dealers repair manual for your exact bike. Start with a search for a pdf version, try ebay, and if that doesn't work go to the Yamaha site. Hopefully it works out for your, good luck!

Great job! What if the motorcycle does not have a kickstand? I am having the same problem with my can am. Every time I press the clutch it cuts out on me. Any suggestion?

[@spelunkerd]

Oh, you mean those 4X4 quads? My garden tractor has a sensor in the seat that will kill ignition if the weight of the rider is gone, as might happen if the rider falls off. Same principle. It also has is a kill circuit if the power takeoff or mower is engaged when trying to start. I'd be searching out a wiring diagram for your vehicle, and look for that. The other way to approach this would be to look for loss of spark when you release the clutch. Use a spark tester to demonstrate spark, slowly release clutch and see if the spark disappears. Then look closely at the ignition circuit and see where ground comes from, looking for alternate grounds. When the pathway through the clutch switch disappears, it needs to find another route. For diagnostic purposes you can bypass those switches and see if the problem resolves. However I wouldn't do that permanently, those safety mechanisms are there for a reason. Good luck!

I have the same bike model. What’s your diagnosis on why my start button won’t start the bike?

[@spelunkerd]

No starts are usually fairly easy. First you ask whether the problem is inability to crank the starter motor, or inability to start when cranking fine. If the starter motor turns we call that a 'crank no start', and if it doesn't we call that a 'no crank no start'. There is a whole algorithm to follow, too long to lay out here. The most common cause of the first situation is bad fuel delivery, and the most common cause of the latter is a bad battery. You need some basic understanding of DC power, you need a multimeter and simple tools, and you need to understand how these engines work. If you decide to put the effort in, you'll find the net is full of simple explanations.

What could be the problem if a dirt bike stalls out when you put it into gear? The bike is a 96 rm125 2 stroke.

If you've ruled out the kickstand switch I'd start from first principles, look for what's missing, spark, fuel, timing, etc. If spark drops out it might point again to the kickstand issue, I'd be looking for a wiring diagram. On the other hand if the engine chokes up under any load I'd be looking more generally at compression and fuel/air delivery, etc.

The previous owner could never get it to run.. -said the problem was something electrical but didn't know what to look for. I am guessing the owner before him hacked the kickstand switch out. The leads for the wlswitch are there and i never thought to disconnect them (yes the kickstand switch leads were neatly connected with banana plugs) to see if that would do any difference.

Just came across this video , my 2001 800a with start fine idle perfectly, nut as soon as I give it throttle, in neutral or in gear it dies , could the kickstand switch do that?

[@spelunkerd]

If it is fine with clutch in, but as soon as you release the clutch it dies, check that kickstand switch. If the engine dies with clutch in as you turn the throttle, it may be dirty jets in your carb, dirty fuel or water in fuel.

Good evening. My bike is a 95 KLX650 and i am having issue with getting it moving. It idles fine in neutral with kickstand down. Manual says this bike has a side stand switch to keep (stall out) the bike from rolling in gear while the kickstand is down but i dont see a switch anywhere near the side stand. Makes me wonder if the previous owner hacked the switch. My bike has the clutch switch as well under the clutch lever. When the bike is running and i put in in gear and begin to let go of the clutch it stalls. I can start it right back up if i hold the clutch back in; but then dies when i start to release the clutch. Any help will be greatly appreciated

Good question! If you can get a wiring diagram for your bike, maybe off Ebay or elsewhere, it will make this job and future tasks easier. A quick way to see if you're on the right track is to use an ignition spark tester to see if spark drops out as the vehicle fails. If spark continues as the engine dies, it is not the kickstand switch! The kickstand switch provides ground for the ignition module, so if you provide the ignition module a bypass test ground then the problem should disappear. I wouldn't use that to fix the problem because it is unsafe, but you'll build more evidence that you are on the right track. Other things, like the neutral safety switch, or maybe even an aftermarket DIY antitheft device, could do the same thing. Check connections, maybe start at the ignition module looking for loose wires or corrosion, then trace back. Good luck!

@@spelunkerd thank you very much for fast response and sharing your knowledge. I have a spark tester i will look at spark. How is a bypass test done to the ignition module? You mentioned a neutral safety switch. Could this be a problem if the bike starts fine in neutral without need for clutch? And starts fine when it's in gear with clutch pulled in

Spelunkerd great vid. My bike is stalling when releasing clutch in first. I am able to take off in 2nd gear though. I will check this, but would you assume cause is something else?

[@spelunkerd]

For sure, it's not the sidestand switch. I don't know why it would stall only in first gear. Perhaps a transmission issue, a mechanical problem?

[@SGrant-ww9zp]

1978 GS 750, Suzuki, and when I let the clutch out in first gear the bike loses power and wants to die so I have to feather the clutch and throttle so that I can get it to catch first long enough for me to get going ...then switch to second and so on with no issues. Any idea what I need to do?

[@stevetanksley1960]

It's something I'm gonna try tomorrow, I thought it had something to do wilh the kill switch. Fix tomorrow and maybe take a short brisk ride

[@cesarmartinez8982]

My man thanks a bunch !!

[@paulk5311]

my kickstand switch has never had contact with the stand as long as i have had the bike. someone previous to me pivoted the switch out of the way so the plunger stays out. today i ran into this problem with the dying when i released the clutch. it happened about 5 times so i wiggled the connection at the clutch lever and the bike worked fine. when i got home i disconnected the switch and sprayed it with contact cleaner. i hope that does the trick. i think you are incorrect when you state the switch at the clutch lever cannot be the fault. a bad connection can be the same as no connection and we know if you just disconnect the switch the starter will not engage.

[@spelunkerd]

It can be a headache to work on a bike with no wiring diagram and unrecorded work done by other owners in the past. With my bike, the wiring diagram shows that a sidestand switch that is frozen in the closed position will provide a ground for the ignition, regardless of whether the clutch switch is open or closed. It sounds like your bike is wired differently, perhaps by a prior owner who was trying to get it running again. As you say, the diagram shown in the video does not include the starter motor wiring, which includes the usual neutral safety switch requirement to prevent the bike from being started in gear, possibly throwing the rider off balance. Good for you to solve the problem, and thank you for recording your thoughts here.

My '81 400 almost stalls when shifting into 1st gear. RPM's go from 1200 to 800?

[@gregschweitzer8478]

Thanks!!! Fixed in 8 minutes

[@danielrudd7661]

Good explanation 👍

[@austinhedstrom9532]

I will try this today

[@adskoyee]

Huge thanks for this!! Problem solved thanks to this video🙏🏻

[@aaronchadwick2682]

Friend has a motorcycle that seems to match this description and I'm hoping this works for him :)

[@OneAuto]

Thanks Dave, interesting to see the Ignition ground paths. I’m not usually into bikes, if my customers ask, I tell them they are missing two wheels 😀Happy New Year!

[@spelunkerd]

Ha ha, you got me laughing already this morning, Rob.

[@darkshadowsx5949]

I dont think my 1977 Honda has a kickstand switch... but I'll look tomorrow. pretty dang sure i had the stand up.

[@trippsetdivine5677]

So I’m dealing with the exact same issue but this doing fix the problem what else could it be?

[@spelunkerd]

I would go back to basics of fuel, spark, timing. If one were to measure spark in my case, you'd find that spark disappears when the clutch is released, causing the stall. It's possible that the ground connection that feeds this connection to the ignition module is faulty, which would be easy enough to diagnose and fix. Wiring diagrams and dealer repair manuals are critical for this kind of diagnostic effort. In my bike, if one of the diodes along that wire were to fail open it would present in the same way.

[@KlingonCaptain]

Okay, I'll see if this works... Thank you for the advice.

[@stephenjankowski7672]

Yoo! Thank you this helped soo much! Bike is on the road again thanks!

[@BuckNakedProject]

So my bike does the same thing but never when going into first. It’s usually going into 2 or third. When I release the clutch it just dies. I can fire her back up and keep on rolling but this has happened to me in an intersection before when down shifting and made me pretty nervous.

[@spelunkerd]

Hmm, I'm not sure. If the stand is up, you shouldn't have any issue with the engine cutting out because of loss of ignition ground, even if the neutral safety switch is bad (because when the stand is up you already have a pathway to ground for the ignition. I'd be considering other issues, maybe a carb issue when low end torque is needed after an up shift. All kinds of problems can happen at low rpm, including vacuum leaks, air intake compromise, bad gas, compression, ignition, etc. The last time I had that problem it was a dirty carb....
