Hey boys. Suzuki definetly knows about the problem. I ordered my 22 in 21. Im in SoCal and was able tobe #3 to receive my new Busa. Problem was almost imediate. I say almost because delivery was in April. By June the problem appeared. Warmer months. Bike running hotter. Anyways, long story short. Dealership called in the Suzuki rep. They were able to duplicate. Suzuki remapped the fuel. Didnt fix completely, but running much better with fewer probmatic starts. Another problem to be aware of. When starting in cold weather (40f) it starts and runs like its missing 2 cyl. Took it to the dealership. They cleaned the throttle bodies and resync. No more problems with that issue. Still waiting for an update to the starting issue. If you dont take it to the dealership, Suzuki wont know how bad the problem is. All my work was under warranty. No cost to me. Be safe boys. ✌️
If I’m looking at this I’ve got this problem! This started three days ago on a 2023 at 4500kms. Put the side down from stanfding stop, in first gear to bring it to a stop in gear in a hill which I never do. Then it didn’t want to start. Went through about three cycles, feels like a fired battery at first, and then turned the whole thing off and left it for about a minute and it started up fine. It’s happened twice since then always hot for example leaving petrol station.😢
Does it happen when the bike is hot and you stop for a short period like stopping for fuel ? If so when you go to start it just open the throttle a bit before you hit the starter and it’ll start without fail. It says to do this in the manual under starting procedure. My bike did this once so i always open the throttle when starting the bike when its hot and its never done it again
Happy to of found this video and albeit it sucks that we have new bikes that are having hot start issues, i have a brand new 23 hayabusa that i purchasex 12-7-23, within a few rides i started having what seemed like a dead battery at times, then i narrowed it down to it only does this when hot, what is happening on my bike is i’ll stop and shut it off, eitjer for fueling up, waiting at a railroad crossing, etc etc, i’ll go to start the bike and the starter acts as if it can barely spin the engine over and two of the times it would not turn the engine over. i’ll let it sit a bit and boom it will fire off with no issue. I have contacted the dealer and as usual they have never heard of such an issue.
Deals hip may not know, but suzuki reps know. I have a 22 and it would do it constantly. Hot or cold. Acts like a vapor lock. Suzuki remapped the fuel. Much better now. But fuel mileage has gone down. On my end, I change the air filter every 5k. This improved it even more. Be safe boys and rubber side down.✌️
Had a hot start issue last summer. Stopped for gas and when I pressed the starter button it was like the battery was dead. I waited 5 minutes and it fired right up straight away. Never happened again. Mentioned it to the dealer. They don’t know what it could be. Maybe I didn’t let the bike do It’s pre start routine fully.
Mine did the same thing 2023 Busa. Hoping it’s a junk battery from the factory. Going to change it out next spring for a good one.see what happens. Also, have a 2013 Busa. did the same thing at first. changed out the battery haven’t had a problem.
Ok Tested a few things on my Gen 3: 1- I added octane booster and it eliminated the issue 99%. Before, it had this issue at least 50% of starts but almost always when hot. Octane issue. As a mechanic, it doesn’t make much sense to me but I did a couple trials and it worked. When I do have an issue, a sure fire way so to give it 1/8 throttle on start. So, this was my result on a new bike that instantly had the issue almost all the time.
I’m having the same problem with my gen 2 I purchased in December of 2023 it’ happend like 3 times in the past 2 months it was hot yesterday I rode for like 45 mins stopped at the store to get a soda came out at 1st it sounded like a week battery then it was just cranking let it sit for like 2 minutes then it starterd rite up rode to my buddy’s house turned it off then immediately tried to start it back up and it started like nothing happend
Damn dude thats the shit i was thinking about in my head. I told u before i was going to get one from Moore Mafia and have them do all the work i dont want to do anymore, i said to myself im just going to put slip ons so i don't have to deal with complications like fcodes anything. U shouldn't have to go throught a new bike like that, ..dude post it when u get it figured out,. Ride safe
Thanks again for stopping by, I can see the dilemma you're in! But it is a new model, and like most new models even cars they have to fix a few bugs. Trust me this will all pass soon.
Did you ever find out what the problem was? Im going through the same issue right now and nobody seems to know why its happening. Im getting very frustrated. Please help if you can thanks@BusaDepot
I added this reply to a previous video but I wanted to give others what I’ve run into. The dealer told me to put 93 in it. Which I thought it had. Prefilled from dealer. Ran through the tank and refilled with 93. I no longer have this starting issue. Starts every time, no binding like issues. Hope this helps someone. If your filling with 93 and still have this binding issue maybe try a different station, not all pumps are created equal.
They checked my battery- all good. Also, if you turn it off and then back on, it starts just fine most times. It’s not consistent with battery issue. It’s consistent with a program issue if they run this start sequence through the ecu. Thoughts?
I've had a viewer that has tuned these bikes and he states that an ECU flash fixes this issue. I'm working on getting in my parts to get mine flashed and see for myself. But that's the only fix that I've heard about so far. Hope this helps, Also my son's new 2023 GSX-R 1000 has done this as well. That bike also has the auto start feature. But he is about to tune it.
I’m an aircraft mech. I need to know which route the electricity takes for the starter. This bike has this self starter thing. It’s gotta be the issue. My bike is brand new and has the issue from day 1. So, how does it know when to stop cranking? Time or sensor? I bet if I eliminate the fancy starter control it wouldn’t do it anymore.
The auto starting is by timer in the ecu, also there is a starter relay. This could be a thing, not sure yet. I'm thinking about replacing the relay. I don't think it's the battery because if you turn off the bike then turn it back on it starts right up. I replied to your last post, and talked about ECU flash. Hope this helps you out some
@@BusaDepot I’m 99.99% sure it’s not battery thing. I saw several post where they said to open the throttle 1/8 and it cured the problem. Maybe it has something to do with the mixture? at times is sensing something different and so it’s not giving the proper mixture to start? So, I’m gonna warm my bike up and wait for it to do it and then do the 1/8 throttle thing. My bike does it at least 50% of the time when it’s warm.
Just put a higher cca lithium baterry in it, i had this problem on my gen2 i greased the starter clutch pins, shafts and it worked, my gen3 is on 7k with no probs though,
Not positive but I am pretty certain it's happened to me after the flash. My intuition is that it's something in the electrical flow/command chart. ECU has two conflicting commands. Doesn't feel mechanical. Pain in the ass with cars behind you at a green light, but on the other hand I don't really stall the bike anymore...
So you have a flashed ecu, but can't remember the last time it happened. That's a good sign my friend, it seems like flashing the ECU might mitigate the problem. Thanks for the information, it helps more than you know.
Hello friend, Suzuki has stated they know this is a widespread issue. Also heard a ECU update is coming down the pipes. If Suzuki does push this update, you might want to check with your tuner and make sure it won't hurt your flash.
Gen 1 & 2 hot start issues were due to "gummed -up" gears, where the starter connects to the crank, correct? Is that not the issue with yours? Just when the weather is getting nice here in Houston 😢
That is definitely an avenue in which I've been looking at, But like I said in my video, it's too inconsistent to be a mechanical issue like that. The gen one and Gen 2's when they had the starter gear issue It was very consistent. We will get to the bottom of this soon. As for my bike, it's ready to go baby. We should hook up and ride soon.
I just got my Gen 3 I have the same issues with my 2024 Busa I can ride for about 15 min in the bike will NOT start I only have 56miles on my bike I will definitely videotape it the next time it does that. I Think it's the ( Battery) it's seen this bike has to much compression 12.1 for a stock battery...
I have received some feedback from shop owners and they are saying that flashing the ECU fixes this problem. Hope this helps you out my friend, take care and thanks for stopping by
I think your on to something, with the electronic control. I personally don’t care for the auto crank feature of this bike. I wish it gave me control not just blindly cranked away. Most cars with this feature have a safety built in that cancels crank it the amperage pull is to high. Either way one thing that I have found to “fix” the crank issue is to cycle the key. If I just hit the kill switch and try again it will do it over and over. I’ve had significantly greatly luck cycling the key and starting over. But my only hang up is the voltage drop at the battery when it’s doing it. It’s a lot. I’ve never seen a relay pull down a battery, unless it’s dead shorted and when that happens the smoke shows you were the issues at. So the only thing left that can pull huge amperage and not let out the magic smoke would be the starter itself. But that does automatically mean the starters bad, just means it’s mechanically working hard. I really appreciate you touching on this subject and tearing apart your bike to look. That cover you pointed at on the left side is the gear reduction and I’ve seen gen 2 guys with the support shaft that holds the idler gear in the cover had the machining a touch excessive which was causing the gear to pitch and slightly bind. I tell you what, if that’s the case that’s a big problem. That’s machined into the block. I’m really grasping at straws here but your right once the bikes started it’s really quite fun. Man I really appreciate you and your willingness to take this on personally. Even if this doesn’t pan out and the bike goes away you still got a sub for life.
Thank you so very much, low fans like you is what makes a small channel like this great. I'd much rather have what I have now with viewers like you who engage with me then have what like yummy noob has where it's just mostly trolling. You guys are the best!! That brings me to this point, Remember a few comments earlier where I said it's possibly a battery or a relay. I'm starting to think that's where the problem lies. I don't mind working on this, lol I'm too stubborn to walk away. 😆 I appreciate a good puzzle. I will test the battery draw this week as well, thanks for the Insight on that with your bike.
Have you tried turning it off by the key? Not the switch? I've been told that flashing the ECU or turning the bike fixes this. Thanks for sharing and let me know about the key.
What I've come to realize about the starting issue or how I circumvent it. I always turn the bike off with the key and turn the key back on it reboots the system before every start that way. Since I started this practice I have not had that problem again. I hope this helps, now I had a man reach out to me who owns a race shop. He said every bike he has flashed the ecu, no longer has this issue. Turning the bike off by the key, Every time always seems to fix the problem for me so I can save that money. Hope this works for you too
@@BusaDepotin my situation the starting engine issue shows only when it’s on the first gear and taking off my hand from the clutch by mistake.. it’s only started working after waiting for a minute-ish.
@@user-xq5xo4tf4h Ok so if you go to start your bike and it's in gear with the kickstand up, for any reason your hand releases the clutch what so ever. The bike will kill the starting process and go into safe mode (for safety). I've found that you can wait out the safe mode, which is like 20-30 seconds. Or turn off the key and then power the system back on. I hope this helps
Most of us have an aren’t getting anywhere. Like he said, you take it to the dealer and they can’t reproduce it so it gets a clean bill of health and off you go.
Was sup my friend, I did take it to the dealership but they were unable to recreate the problem. As you know, they can't fix what isn't broken. It's so random and so far between I mean it's only happened to me twice. But others out there are experiencing it on a regular basis. With any new model it's going to take them time to work the bugs out but I have faith this will get all sorted out in time. Thank you for jumping in, I really appreciate it!.
@@BusaDepot yes, I should have waited until the end of your video as I noticed that you did say you attempted to get the dealer involved. Fortunately I haven’t had any of those issues and hope I don’t. These are the type of issues you would expect a Harley to have, not Suzuki or most of the other imports.
I agree with you, my Harleys did stuff like this. But I'm getting word that Suzuki is working on this and should be pushing a ECU update sometime in the near future. Lets just hope this comes into fruition.

What if 91 is all that's available (most of california)
That’s not the issue. 93 compresses exactly the same. It just has a slower burn rate.

If its a heat issue, wouldn't the bike do this every time you turn the bike off, and then try to start it? The bike gets hot every time you ride it.

When it does it crack the throttle as it turns over will fire right up.
