GEN 3 starting issues
- Thread starter effyzx
- Start date
I’ve had this happen twice on my gen 3. Once the day I bought it I pulled over to call my wife and when I restarted it acted like it was kicking back on the starter, I kinda figured the battery might have been low from sitting on the show room floor, the second time is when I stalled at a stop sign and when I pressed the button it again acted like it was kicking back then it started, also when it’s kicking back you can’t stop it because the computer is trying to start the engine. I’m sure I can stop it by turning off the key but when a car is behind you waiting on you to proceed the pressure is on, plus it won’t start in gear so when I went for neutral I put it in second then had to go back to neutral and that’s when it had the slow start. It’s really hard to look cool when you stall your bike and it doesn’t start properly. Lol
Correction on my above post, the gen 3 will start in gear, I tested it today. It didn’t restart right away on the day I stalled it, I guess I couldn’t hear it because of full face helmet and like I said earlier the pressure was on with the traffic waiting behind me.

I have video of this happening!! Presenting to my dealer next week when I go in for the 7,500 mile service. Between now and then I'll try to get the video clip in a comment here.

For your viewing pleasure (or displeasure damnit)
Gen 3 Hayabusa fail start
Edit: may need to download if you want to see the video. Droplr being stupid. The bike is *not* overheating. This happens to me all the time. Cold start it fires up every time. However, I can cold start the bike and let it run for 10-30 seconds, kill it (key off), restart it (key on) and this will happen.
I make sure the bike is in neutral before I try starting the first time. Start failure.
I then roll the bike forward a little and try again. Start success.

The "starter flat spot" is not referring to an open-circuit on the switch which is to what I think you allude. It is an issue on the starter motor where part of the armature windings are damaged from heat. If the starter lands right on the damaged coil area when it stops spinning, there is no torque created by the field on that spot, so it will not turn at all on the next start attempt. One used to bash the starter with a sledgehammer to jolt the armature / spin the starter just slightly and get it off of the bad spot. Then the starter would spin right up.
The flat spot means no turning at all. Has anyone seen this on a modern motorcycle?

That’s EXACTLY what I’m not eluding to.

Hm... I always swapped the factory battery's in my all my bikes as first mod. I currently own a 2003 gsxr600, 2005 Turbo Hayabusa, 2006 Gsxr1000 and 2022 Hayabusa. Might want to think about a good battery upgrade, seems to be more than just weight-loss. More like properly running bike mod too lol

It happened to me too. Bike taken in January, now 10,000 km. Yesterday after 100 km at a "normal" gait I stop in front of a group of five young people, anticipating an envious interest. I turn it off with the kill switch, but I have to turn it back on immediately to move it half a meter. Surprise and Embarrassment. The starter runs very slowly as with a flat battery, which however marks 12.8 V. I try several times, turning the key, but always the same. After five minutes I try again, ready to ask the young people for a boost, but he leaves without problems. Then after several kilometers it turned on and off about twenty times without problems. Let's see what the dealer will say

So I rode the bike 4,000 miles from Cali to Texas. Lots of starts. I figured something out.
Before my trip and since I bought the bike new, I did the following:
1. Bike off.
2. In neutral.
3. Pull up kickstand.
4. Turn key.
5. Wait for gauges and display to load. (SO PRETTY).
6. Tap the Start button.
When the bike was warm or hot, the start would fail around 50% of the time. (Cold starts work 100% of the time for me.)
On my trip to the Big D and back I stopped for gas a lot. I got in the habit of leaving the bike in gear when filling up. I realized that if I left the bike in gear, put up the kickstand, pulled in the clutch, turned the ignition key on, and immediately tapped the start button (before the gauges and display stuff starts, the bike started every time (warm or hot).
It starts every time like that. I don't know why, but it does.
1. Bike off.
2. In 1st gear.
3. Pull up kickstand.
4. Pull in clutch.
5. Turn key.
6. (don't wait for gauges and display) Tap Start button.
I hope this helps other folks with the same issue!

I hope it’s something simple like that. I feel it’s something in the programming, either computer or sensor causing the issue.
I picked up a big CCA lithium battery yesterday to try and see if anything changes also.
I'll bet that's not in the owner's manual under starting....
Hot bike doesn't start | Gen 3 Busa Information
I ran into this problem yesterday after a 30 minute commute through the city (slow crawl 99% of the way), so the bike was quite hot (temp gauge was normal, but my legs were being cooked!). I went to park the bike on the street, so I normally turn it off first then back it in behind a car. I...
Mine does it on the side stand.
I also shut it off with bike in gear and usually use the side stand to kill the engine also, not sure if that has something to do with it or not.
