GEN 3 starting issues

The nightmare returns! After three perfect months, yesterday I had another problem turning on at the traffic lights and not even too hot! Started after 5 minutes and never did it again. I had changed the starter motor and gears. I'm desperate, even out of warranty

That would be most frustrating......I'm sad to hear this...
 
Had this issue on gen 2 everytime with hot start. My guess it is something to do with internal of the engine expanded due to heat so i changed battery to Lithium with higher output. Never had hot start issue again for the next 5 years of ownership.
 
I’ve had the issue from day one on my 24 Gen 3 Busa, described it to my dealer at time of first service, they did a software update and it has resolved the issue for me.

I was recently told by my mechanic there is definitely no software update, and to prove it he showed me the SDS2 when he connected it to my bike. This may mean my bike had the updates installed at the factory?? As for the hot start issue, he checked with Suzuki's head technician (in my country) who confirmed the fix is to replace the torque limiter assembly.

well, if youre reading this entire thread apparently the 'software update' was not true.

Interesting as I waited at the dealer for the first service and “software update” to be performed as they had indicated was being done and the bike has never had the hot start issue again vs it had the issue every time it was started when at operating temps for the first 600 miles whenever I forgot to open the throttle a little upon starting which would always solve the issue.

I know the issue went away for me after they did whatever they actually did in the service bay and what they told me was that it was a software update so not sure what to say if others are claiming this is not the case and given the issue did go away in its entirety I have no doubt something was in fact done and don’t know why the dealer would have made something up vs just saying what was done to rectify the issue.

In either case my apologies for any misinformation if what I was told was incorrect and I hope anyone still having the issue gets it resolved on their bikes as it was a little annoying to say the very least.

My gen2 presented the same 'heavy cranking' when hot. But, never, when cold. Considering the viscosity of the oil being higher when cold, it 'should' be easier to crank when hot, not the opposite. So, the battery wouldn't be the cause. One day I heard a plausible explanation and a corresponding solution : the presence of fuel in the chambers, and their untimely ignition. To avoid it, open the throttles just a little and hit the start button. Yes, it works 100%..
