Picked up a 2022 GSXS 1k and it’s the best bike

Congrats and nice bike! I just saw one yesterday while out on my GT! You do need a tune anytime you change exhaust or intake on a bike if you want to realize the most potential and make sure it isn't running too lean. Chris Moore (Moore Mafia), Jason Karns (Karns Peformance), Two wheel dyno works, and Danos are all very capable mail order tuners.

Welcome and sweet bike. What windshield is that? I like it.

I have the same bike and same pipes. While M4 claims you don't need to tune, it's probably a good idea to do so. Even without changing the exhaust I would do it. I sent my ECM to Dano's performance in California and it's like a new bike. He removes all the crap Euro 5 restrictions, optimizes all the fuel maps, disables the O2 sensor, pairing valve and exhaust servo. He also gets rid of that annoying "fuel cut" on deceleration. It's like a new bike and he only charges $200.

Great pricing! I wonder how his work compares to Chris Moore and 2WDW?

I'm curious too because I was going to use Chris Moore. Ive been binge watching his YouTube channel.

From what I have read from other guys on here, Danos has a LOT of dyno time with the GSXS1000 may have been a personal bike of his, so out of anyone's when I send mine, it's going to him.
& mine being a 16 doesn't have a QS, so may also get that. $445 for flash & QS🤙🏼😎

I just looked at Danos website and it all sounds great except for the needing to reset the check engine light. He said it requires a diagnostic scanner and an OBD2 adapter. You can rent it from him for another $160 dollars. Do they all require to do that when you reinstall the ECU? I don't mind doing it, it just costs more than expected. $200 for the flash and 160 for the rent.

The reason I ask is the 22 and up bikes do not have the exact same engine internally, so they make power differently. You can buy a $30 OBD handheld and a $10 adaptor. That will also allow you to reset the maintenance reminder instead of using the wire/paperclip trick.

Ahh ok cool thanks!

I took the bike to my dealer and they reset the light for $25. It took them 90 seconds. Yes, with the 2022+ bikes any modification to the ECU will throw a light. This was not the case in the 2015-2021 bikes.

Your bike looks sick and have fun dude 😀

I was looking at buying from a dealer but happened to find one near me that was nearly brand new. Best part is the guy spent a TON of money on modifications that I was going to do anyways which was perfect! The full M4 exhaust is very loud so I had to put a silencer in it. I have a few questions though. On M4s site they mention you do NOT need to flash the ECU and said the bike runs fine with a full exhaust. Can anyone confirm that? All my old bikes I needed an ECU flash if you removed the cat.

My bad for not answering your original question earlier.
I have a 2016 with full M4 & have not done anything with the ECU. Zero issues & don't get the decel pop when normal riding. I can make it do it to an extent but have never has crazy popping/backfires. & my pair is still intact right now. Plan on removing once I get a flash. I'm sure I am slightly lean with the exhaust.

As stated you definitely 'should' #1 to get rid of restrictions and make it run as it wants to.
Like for years before flashing was a thing & everyone was putting Power Commanders on everything.
I really want the FTECU (2WheelDynoWorks offers) or Woolrich harness to be able to tweek on the tune on the laptop myself. Yes it's a little more expensive but you get unlimited tunes on your ecu. You change exhaust, can change tune, change air filter, can go in & tweek...

You don't need to spend $160 for a rental. You can (and should) buy the diagnostic OBD2 + adapter. Total cost is under $40. The OBD2 scanner will also clear error codes. Because I'm a cheapskate, I bought the $11 screen less OBD2 scanner which also clears codes.

There's also a bunch of user-changeable settings that you might as well reflash the CPU on your own. What if you think you like no engine braking and then realize you want a bit? Or if you move to Denver?

Be warned; the more modifications you do to your bike, the more fragile and unreliable it becomes. I estimate about a fifth of groups rides end up in a roadside fix from fairly minor things like tail tidy's/turn signals, EXUP/O2 sensor removal, cheap chain replacement, rotating handlebars, etc...

Motorcycles aren't THAT complicated especially if you have the shop manual, but having a single OBD2 scanner for all vehicles you come into contact with is pretty useful. You can replace the part and clear the OBD2 code. I just replaced one of two faulty TPS on a 2002 Nissan which would have been impossibly difficult before the OBD2 standard.

Yeah I don't think I would be screwing with much, but it does sound really good to have.

That may be true if you don't know what you're doing or if you're using low quality Ali Express/eBay/Amazon parts from China. Swapping in a nice exhaust system, a different set of handlebars, a fender eliminator, ecterea, will not automatically lead to a fragile and unreliable bike.

Also, removing the oxygen sensor, exhaust valve, and pair valves leads to a more reliable bike, IMO. Deleting those items means having less sensors, solenoids, motors, and other mechanical/moving parts to potentially fail. When done properly and flashed/tuned to account for the changes, these things being out of the equation equals an increase in reliability, not a decrease.
