ZX-4R ECU - SAFE TO FLASH ?

[@MotoMischiefs]

I bought two 4RR's , one for him and one for her as featured on my channel. In my case, I have been pondering the issue as well and decided to use the bike as intended in factory form until the warranty runs out, AKA make it sing at 16k. If the problem has not presented itself by then, I am assuming it should be safe to flash the ECU. At the moment, like you said, it is a UNICORN and there is nothing like it out there.

[@tsdmoto]

Appreciate the feedback and I hope you have two good ones!

Greetings from Australia. I recently bought the 40th anniversary edition. Smooth sailing so far. We have the full power version, as does the rest of the world i think. No engine issues reported here so far although most riders are aware of the issues. As you rightly say Kawasaki needs to make a statement on this as so far, as far as i know nobody has crashed when the engine has let go but the thought of the engine letting go while powering out a corner and back wheel locking dont bare thinking about. As you said & i agree, i didnt buy a 400cc four to potter about under 6000rpm and Kawasaki surely knew and expected these would be ridden hard at very high rpm. I just hope they address the issue before somebody is spat off, injured or worse

As a factory car mechanic and getting TSBs for stuff like this. We don't fret at all about the issues. If a customer is an insomniac over the machine. He's half the problem. Machines are machines and we make money even when they break. I knew of these issues on this motor but bought it anyway. I went with the 5 year oem warrantee. And trust me HONDA has problems too. In their car division, warrantee is RARELY used. "Hey ITS A HONDA'. YOU BROKE IT. We're not warranteeing it. Relax. Tip the service writer and ask for the best mechanic in the shop. A box of donuts won't hurt. Jeez.

Currently i am not worried, i do wonder if this is maybe related to people blipping down and over revving the engine but I am happy with my zx4r and currently confident with using it, but I am definitely keeping my eye on this issue.

[@openscholar9908]

It would be nice if you could just order the foreign ECU that will make power to 14k.

[@tsdmoto]

That would be amazing. I had a Ducati Streetfighter a while back and the upgraded exhaust came with a performance ECU that didn't void your warranty. If Kawi could only do that.

[@Clayton.Wilson]

Love the zx4r content!

[@berttompkins9096]

I need the part #for the foreign ECU. ANYONE? PLEASE!!!

[@pawneetsingh6448]

I have family back in India, if I get an ECU from India will it work here in US ZX4RR?

[@openscholar9908]

@@pawneetsingh6448 It should. If they are not to expensive it would be worth a try.

For all those who have a zx4r or rr, after 13k miles I noticed the low oil problem. I am in the process of doing the 15k service as I have more than that. The oil leak seems to be the valve cover and the gaskets on the bolts that hold the gasket down. Also make sure that the alternator cover isn’t leaking as that recall involved a gasket as well. Hope this helps.

[@tsdmoto]

Thanks for sharing that!

[@Elvis_not_Presley2]

@@tsdmoto No problem. Like you, I may do the CBR400 because I just love Honda but I really love the Zx4rr . It does absolutely everything!

[@msromike123]

Option 4. Buy a second ECU and flash it.

[@tsdmoto]

I wonder if you can pair a second ECU with the bike

[@msromike123]

I don't have a problem with taking down a post after I get a warranty repair after a flash. That's the way things work in America.

[@tsdmoto]

Feels like we should explain what happened and that it all worked out in the end. Feels more transparent that way , no?

[@msromike123]

@@tsdmoto No problem with your approach. I respect it! Just not sure Kawasaki is doing anything too shocking here. :) I appreciate your vid, immensely! No matter how much I wanted this bike, your vid helped me decide. It's on to the all-in cheaper Tuono 660 Factory, lighter, better handling, more hp, better electronics, IMU, and can ride it stock just fine. After researching the things you pointed out, came to the conclusion option 0 is my route. I mean that Kawi 16k redline is amazing, and the sound, but...

[@tsdmoto]

@@msromike123 Tuono 660 Factory , I totally get it, that's a SEXY bike and has it's own epic sound with the 270 degree crank. I mainly bought this bike out of FOMO but starting to regret it.

[@VictorRaycroft]

i love my 24 zx4rr i couldnt get through your vid because of the incessant whining , hand ringing and worry, dam bro.

[@hokogan]

I think the “very vocal individual” is having warranty problems because the bike was fully track prepped. Racing breaks parts. Seems other people are getting warranty coverage even with a flash.

[@tsdmoto]

Fair point, but I'm glad someone started a group for the issue.

[@hokogan]

@@tsdmoto Yep. I’ve been planning on picking one up next year, but I definitely want to know why it’s always that same rod punching through the case.

[@msromike123]

@@hokogan Well no consolation to current owners, but I would wait for a 'These kinds of things typically get fixed without much fanfare. Kawasaki doesn't want to keep fixing motors under warranty, and they don't want to signal there is a problem. It will be addressed by engineers and/or on the assembly line.

I have 6 days to buy the extended warranty on my zx4rr. Not sure want i want to do. I have 1900 miles on my bike in the past year.

Gimme the ECU part # from Down Under please!! Dealer cant access it. I dont want a reflash to keep the other parameters intact. Like converter and idle injector cut out.

[@abyb1923]

I noticed you bike is black but it say “rr”. Is it possible to get the rr in black ? Is your a r or rr? I want the rr but cant stand the bright green “look at me” spec.

[@tsdmoto]

Mine is an RR and it's black. I'm not sure where the rumor came from that you can't get an RR in black.

[@slyman0057]

​@tsdmoto The only black for '23 was a ZX4R (single R). The '24 ZX4RR then also became available in black.

[@berttompkins9096]

This is just like the worry warts over the KLR "THINGAMAJIG" PANIC OVER internet squalk.

[@tsdmoto]

At least there is a cheap fix for the KLR DooHickey, nothing has been ID'ed for the ZX4R platform.

[@imrin4059]

I heard zx4r has lower power then zx4rr

[@tsdmoto]

😄

[@ironzombi]

This is not true no difference in engine performance.

[@turbonoise]

No engine performance difference between the R and RR- the RR gets fully adjustable suspension and a quick shifter, no engine differences.

[@imrin4059]

@@ironzombi i just searh it was like smaller piston bla bla. But in sweden were i live is like full effect 77 hp stock

[@jenqq8514]

if youre not living in US is it still worth it to ECU or nah?

[@tsdmoto]

Maybe someone outside the US can weigh in, but if it was me, probably a nah unless it enhanced throttle response
