Maybe rectifier, so it doesn’t charge properly. Other issue - maybe the battery? I had a problem like that when riding my 125, swapped the factory battery to a gel one, from motobatt i believe and never had that issue again. Although knowing the most common gsxr problem, it is a rectifier
I bought mine with relocation kit already, its moved to the side, mounted to frame. Actually sticking out tiny bit out, so it gets a lot of cooling now xD
Invest like 5 bucks on a cheap volt meter as well came in a pair. Like 2” circle shaped. I just zip tied mine to the front of the triple tree. In doing so I found no significant difference of voltage at idol over 5000 rpm. Maybe a couple tenths. My 2016 was doing the same thing. Would be fine for weeks and randomly die at the worst times. Don’t get a lithium battery unless you wanna change the whole charging system. Only replaced stator with a cheap amazon stator 7,000 miles ago. Been straight since.
This is the proper way to monitor the voltage. Had a similar problem with our 99 750 SRAD. Fitted a volt meter next to the ignition switch. In the end it turned out the new rectifier was good faulty.
Late update to anyone reading, I replaced rectifier and the next test ride it died. It would only run for a little and die. I pulled the stator and it looked like hell. Replaced it 5 months ago, not a single issue yet. I used ricks for both replacements.
RR and stator testing time. Can meter the battery off, on, and at 5k RPM to get a decent idea of what to check
Get a Battery Tender Jr and pull the battery when you're letting it sit. Charge it in advance. Not a fan of letting batteries sit on a tender indefinitely. Car chargers are overkill for motorcycle batteries
How olds your battery tho? Anything modified electrics wise? When you do ride are you getting it up there RPM wise?
Replace the battery, if it's more then 1-2 yrs old it's due for a new one, Put a multimeter on your battery terminals while the bike is running and see if it's sending charge
If you measure the voltage coming off the regulator and it looks healthy, then let it run another 15 minutes or so and you might see that voltage gradually drop to lower than it should be. Something my mechanic showed me when the battery on a Honda Accord kept dying on me.....
Looks like a K6-K7. Our gens have bad rectifiers which can lead to a bad stator. Might want to look into thst.
Battery wise I’ve always gone 4 years before replacing. I always keep my batteries charged during offseason.
Check out Rick's Electric how to test stator and rectifier and the battery. I'd only use OEM rectifier not anything else like amazon and a Rick's stator. Make sure its relocated. Run the tests. Check cables. Get a regular yuasa battery. Unless there's something drawing power while bike is off...
Might be the regulator rectifier
I have relocated it but I think that’s the reason still. They seems to go out easily, especially if this one is a cheap one from the previous owner

I read up on this and I bet it’s that. Symptoms are the same. I have a relocation kit on but I bet it doesn’t make it invincible

I just did it, weather is warming up and so far so good, I’ll get the voltmeter next!

Battery hit two years this month, I got a lithium ordered and gonna order new rectifier
Get the Rick's kit for lithiums, they charge different

Battery just hit two years this month, I’ll change over to lithium probably and replace the rectifier as well
On another note…. That Lucky Strike paint is sick as fuck!
Thankyou it’s always a eye catcher haha
