Review and Cold start on Ivan’s tuned z900rs

[@Iatolaazzahola]

Finally, a sensible guy that doesn't rev his bike to the moon to give a sound clip. Good info.

[@MChappysGarage]

She was cold too lol no high revs when the bikes cold

[@wrenchrat]

The best is when they stick the mic right next to the exhaust so it immediately clips out XD

[@85stangster]

Installed my Ivan's tuned ECU yesterday, along with airbox mod and Akro header. Sounds a little deeper. Chomping at the bit for a ride today!!😁

[@stratolestele7611]

Man, I love it! My '23 café isn't even broken-in yet, but it's still got a great cold start. I love hearing the ecu do its thing. It sounds like a 'works' bike even stock - to me at least. You're right, about the chop. Very cool. I'm looking forward to tuning mine. Thanks!

[@stratolestele7611]

Wait..."gets rid of decel popping."...? Man, I love that popping!

[@mikejohnson9118]

For a reference...go listen to the older carbureted performance bikes. They have a "Cammed" sound to them. The idle kinda rolls back and forth.

[@elvis_chen]

Sounds wesome! Please share more after putting more miles, do you still recommend it?

[@claytonlh]

Great setup. Sounds amazing. I really want to get one of these. I had a 84 GPZ 750 with a Vance & Hines exhaust. Vid on my channel. Man i miss that bike. Should have never sold it.

[@jared-mz7kv]

I have questions I also have the Akro header with stock can did you have to put gasket silicone where the stock can connects with the akro header mine leaks/has blow by. Just wondering if yours did the same?

[@dmenaced]

Got my ecu back from Ivan and now my exhaust is quieter. I’m not happy about that. I paid good money for a louder exhaust then I paid Ivan to ruin the sound. How does your exhaust sound compare after the tune?

[@creed426]

Thank you for sharing the video-it was a wonderful sound . I'm considering getting the same myself and have a couple of questions if you don't mind. 1. Are there any aspects of the bike that you regret? 2. How do you decide what settings to choose on the ECU for better performance? 3. After tuning the ECU, does the bike's warranty remain valid? Thank you again.

[@MChappysGarage]

@@creed426 hey thanks for watching, to your first question no there is absolutely nothing I regret with this bike. It’s an amazing bike, quite comfortable for cruising around town and having some fun. As far as the ecu flash when you send the ecu off to the tuner you tell them which modifications you have in the bike if any and they do most of the adjustments on their end. The Ivan’s tune greatly improves the throttle response on the bike so it’s not as twitchy as the stock tune on the bike along with turning on the radiator fans earlier so the bike doesn’t run as warm and a bunch of other things. And yeah tuning the bike will void the warranty however I wasn’t too worried about that.

[@creed426]

I must own that sound! :) Thanks for the upload

[@MChappysGarage]

no problem, everytime I start it, it is music to my ears

[@wrenchrat]

Have you ever felt the need for a steering damper on this bike? I'm coming from a ZX10 that has one and I'm wondering if its necessary for the Z900RS

[@MChappysGarage]

So far no, I’ve had it to 140mph and it’s pretty rough with the wind but the front is stable

[@ccools626]

What did you have your rev limiter set to 9800 or 10300

[@MChappysGarage]

10,300. Sorry for the late reply

[@jtwu8931]

Bro, I timed the cold start and I stopped at 3:30. That is very long to warm up a nonexistent cat. My Zed will only return to normal idle with 2 bars on the temp gauge. I have the same setup like yours: Akra headers, stock can. I am not sure I want the Ivan flash after watching you because it still has high idles for very long time to warm up the cat. My GS only takes about 1 minutes to get up to operating temp and it has a huge 1200 cc boxer engine. Can a lower thermostat be used to let the coolant warm up faster?

[@MChappysGarage]

Every bike is a little different, it ramps up to the higher idle to get the motor warmed up before ripping on it. The gs has a completely different motor than this bike

[@gtrs4ever]

Is this the latest ECU tune from Ivan? I had mine done in Sept 2020, and just sent off my ECU for a 2nd update (May 2023). Hope it's a much improvement, had too much engine braking and too much fuel shut off at low speeds. Scheduled to receive it tomorrow...can't wait!

[@MChappysGarage]

It was tuned around the time of this vid, i am not sure if it is the most recent

[@ahbalone]

Sweet tune❤

[@Max-kh9do]

Michael, how is the exhaust sound when cruising? Is it so loud that you get a headache?

[@MChappysGarage]

I don't think it is too loud, that all depends on the person though. The tune actually made it sound deeper so its not as high pitched without the tune. It definitely drones on the highway though around 75-80mph

[@Max-kh9do]

@@MChappysGarage Thank you!

[@iFumoffu]

Hey mate, did the ref lash solve the choppy/snatchy/jerky throttle completely?

[@MChappysGarage]

Yes I would say it got rid of 90 percent of it

[@MrMoto948]

In Oz we have winter and summer fuel. Runs against the grain for me to do a tune without doing any tuning. Just wonder if a PC5 would clean everything up. I have a summer and winter map on my PC3, I added an AFR and TPS gauge and video'd the runs to tune my V twin. I then put it on a dyno and the tuner said it was running a tad lean all the way through. The RSR AFR gauge has two leds that indicate 13.5:1. I tried to get it in the middle, after dyno it is now on the yellow led closer to the rich side. In winter it just runs rich and have given up dragging the laptop out. I will stick a self tune module on my rs with a PC5 as I cant get used to riding a bike without a quick shifter.

Hi Michael. I enjoy your videos and am a subscriber. Do you have one on tank removal and air cleaner replacement? Thanks

[@MelloYellow510]

What do you think about the seat? I hate mine! I’m 6 ft tall it feel’s too wide and hard. I’ve put in 2200 miles it still hasn’t broken in.

[@MChappysGarage]

I am 6'2 and I dont hate the seat after about an hour it is not super comfortable. I will eventually go to a better aftermarket one

[@seriousandy6656]

I have a '22 with the Akro header and Muffler. I haven't sent the ECU to Ivan yet, but this bike sounds alot smoother than mine. I have a KN and will remove the divider. Not sure about the V stacks, definitely will not be drilling the holes. I don't need the extra 1 HP.

[@MChappysGarage]

Ivan actually recommend for me to not do the stacks because it effects low end torque and only benefits you on the top end. I didn’t drill the holes either. Just removed the divider and k&n drop in

[@radiffff]

Hey, what’s the model of your stand?

[@jefframirez4820]

beautiful!

[@jasonmeador124]

Is the Akrapovic header also a cat delete? How much louder than stock is it?

[@MChappysGarage]

Sorry for the late reply but yes the headers delete the cat, it is much louder compared to stock. however once you tune it, its quieter somehow lol

I did not drill the holes in the airbox or change the air stack things. I wonder what the difference is. I now want to do it but don't know if the ECU needs to be re done. Still, massive improvement. It's a new bike

[@MChappysGarage]

I didnt drill holes either, I just cut out the divider and did the k&n filter

[@jameskeathley7244]

having done it a bit ago have you been able to determine what impact it has had on your mpg?

i get around 35 but i really dont care about mpg on the bike

[@jameskeathley7244]

@@MChappysGarage Thanks. I have one and I have veen debating doing this but 35 is a bit low for me.

[@pattate67]

I picked a 2018 up with the brocks full system and ECU tune already done , I just did all the Ivan's air box mods , it already had the sprint filter from Brock but I did the divider mod and the stacks and the 7'8ths holes in the front .. I'm not sure I like what it's done to the acceleration response so I've ordered the 7'8ths rubber plugs to start winding back on air in the box. Idk it just seems it's over reving on the power band now , lost a bit of torque maybe or it's the clutch slipping .. maybe

[@zachv8286]

Swapping back to your stock v-stacks will help restore low-mid range power as well. The short stack benefits are mostly seen at 8k+ RPM - you’ll get slightly higher peak numbers with them, but at the expense of a hit to your low and midrange grunt.

[@onerider808]

Cool looking bike.

[@aggyslacker]

Great work on the bike! Are you planning on swapping out the stock can?

[@MChappysGarage]

I’m not I love how it sounds with the stock can

[@aggyslacker]

@@MChappysGarage I do as well! It’s one of the best looking and sounding stock cans ever! I purchased a 2022 Z900rs a couple weeks ago and want to follow some of the steps you’ve done in upgrades, but I’m a little worried about the warranty on the bike if I do. Any thoughts?

[@seriousandy6656]

MPG is dependent on how you ride it. If you're super easy and spend time up in 6th gear, you can average close to 50. If you are into the throttle all the time, you're going to be in the high 30s.

[@damacknificent151]

50 mph is with the ecu being tuned? Or we are talking stock? I currently have a 2020 Z900 did 60 mile trip on the freeway with elevation gain of 3000ft. I did 51.3 mpg doing 70-78 miles per hour. Not really opening it up.
