2022 Busa Overheating

[kim windsor]

Likely the bike came dry (no fluids onboard) to the dealership. Their service department probably f***ed up when they were prepping the bike.

I believe yours is the first we've heard of a lemon potential re: Gen 3's

That’s my guess also never serviced properly when arriving at dealer, I checked
mine as soon as I could and dealer did not mind at all.

Rocket, do you have the bike or is it still at dealership and do you have the tech manual for the bike yet?

Bike is still at the dealer. I do not have the tech manual. Only the owner manuals it came with.

Well, we’re all guessing but I’d like to know how it ‘stalled’? Just die idling or stall when you let the clutch out to go? As for the heat on your legs, you shouldn’t have felt any in just 500 yards in normal weather but, w/o any riding gear, just jeans over skin? like many Harley riders wear, the heat can feel excessive. Compared to most big twins our motors are actually small and being water cooled, generally run much cooler.

I think I mentioned, I shut the bike off via the starter. I was in 1st gear. It was off for about a minute while I was showing my ID to the sentry to enter the base I work on. When I went to start the bike, in first gear, clutch engaged, the bike would not start. Think of hitting the "start" button on the bike, and hearing the engine trying to turnover...but not. I tried multiple times. Ultimately, I let it sit for a minute or so, and it eventually started, but at that moment, I did not look at the temp gauge, nor did I know the bike was overheating. It wasn't until I parked, about 5 mins later, when I recreated exactly what I had just done, looked at the entire bike, and noticed the temp gauge.

I was able to physically view the fluids (coolant, oil) during delivery, so it wasn't dry.

I had similar issue with engine shutting off or not starting on my bmw and it turned out to be a bad crank position sensor after lot of back and forth with the dealer. Just sharing

I still think it had/has air in the system causing it to overheat and shut down..

I guess the report from the dealer will tell us....

So...Took home my 2022 Busa after Labor Day. Rode the bike daily to acclimate myself. After a <10 mi ride to work one morning, I shut off the bike temporarily while showing my credentials to enter the facility. When I hit the start button, the bike stalled. I didn't know why. I "walked" the bike out of traffic to the curb, waited about 30 seconds, hit the start button, and the bike started. When I got to my parking spot, about a mile away, I recreated exactly what I'd done previously, and the bike stalled again. This time, I took a look at the entire bike, and noticed the temp gauge needle was about to burst through the glass!! The bike was overheating like crazy! The needle was past the red zone!! The bike sat outside the entire day, and when I got on around 3:30 that afternoon to go home, the moment I started the bike, from cold BTW, the needle shot up to the 3/4 mark! 500 yds down the street and the needle was back in the red zone! I rode the bike home, called the dealer, and they picked up my bike the next morning. It's been at the dealership for 5 days and they have no idea what the issue is. Did I get a "pandemic lemon"?

Take it back to the dealership, its still under warranty, may be a faulty engine temperature sensor? Does the fan motor switch on ?

So slight thread jack, found myself going down a rabbit hole yesterday and for anyone interested the bottom mark on the coolant temp gage 811ohm is ~50c (122f), the middle mark 142 ohm is ~100c (212f), and the top 111 ohm mark is ~120c (248f). The radiator cap begins to lift at 15.7 psi which at a 50/50 ratio and all things being normal would be about 135c (275f).

There you go, now you've got some test data to work with. Great information. Thank you for doing all of that.

It's already at the dealership brother.......we are just waiting with @Rcktsientis99 keeping him company until his baby is returned...

For what it is worth, I replace my coolant every two years and never burped or rocked the bike or did anything special. Just added the coolant to the radiator and the coolant bottle, let it warm up and sort itself out. No issues ever.

I would check two things, first you may have a faulty thermostat, most probable if the bike is not throwing codes. If that is OK, check your electrical sensors.

Ah modern technology...

(...) I do not have the tech manual. Only the owner manuals it came with.

get here the gen2 manual
for free
because technically around motor and chassis, incl. the abs, the gen3 is equal to the gen2

at main electronics the gen2 differs completely from gen3

Dealership replaced the temp sensor.

Did that fix it?

I don’t know. The dealership still has it. Haven’t heard from them today.

They probably logged on here at the ORG and started reading your posts and thought what the hell I'll give it a try. Lol!

I actually sent my service advisor the link to this thread. LOL!!

Well if it helped then, "Way to go ORG !!!".

They're either going to say, "man there are some really smart people on that Hayabusa board, we should check back periodically", or they're going to say "those folks are crazy".

This info is worth saving:
