only thing i miss is before and after sounds! great vids mirius !

[@MotoMirius]

Thank you. Sorry about that but she was a bit excited about getting the bike back and taking it for a ride to see how loud it was! Skäl. David

All exhuasts should be like this.. can be a pain in the backside with the exhuast paste sealants with the other ones. Good video buddy.

Thanks 👍Skäl David

I was waiting for you to start her up and let us hear!!!

[@MotoMirius]

Well that was my plan too Rob but dealing with the O2 sensor took time and I gad to give the bike back! Skäl. David

[@MotoMirius]

Headers are sized to engine size. Going bigger doesn’t automatically translate to additional power. Power losses are typically in the emissions control parts of the exhaust.

[@Stoqten]

is the exhaust the same for gsxs and gsxr?

Hey David, excellent step by step as always brother . Peace and love buddy 🤘🏻✌🏻☮❤👍🏻

Hi @Moto Mirius I got this same bike and ordered myself a Yoshimura GP Magnum Cyclone complete exhaust system. I noticed some comment that a exhaust gasket may be needed. Is that right? If so where does it go? Between the engine and the exhaust header? Thanks! Great video!

[@MotoMirius]

Yes, it's normal to replace the header gasket when changing the exhaust - if it is a brand new bike such as here you may get away with it.

[@AceRocketLeague1]

Hey mate! Great video :) You say in the video that you prefer to unplug the O2-sensor but do you have to do it? or can you complete the exhaust install without unplugging it. When you unplugged it, did you remove the motorcycle cover that is covering it or did you do it without putting it off. Thank you!

[@MotoMirius]

Thanks. Much appreciated. Yes you should always unplug the sensor otherwise the wire will get twisted. Trace the O2 sensor wire back from the exhaust and you will find the plug which is easily unplugged. Designs vary between bikes, but its just a standard plug - you just have to figure out where to push on the plug to release the lock. Since this isn't my bike I don't recall exactly what this is on this one but it is obvious if you look at it.

[@AceRocketLeague1]

@@MotoMirius Thank you for the answear. Have a great day sir!

[@surfer-meister1867]

i have this same exact bike, and i have a question about the engine/transmission; I have noticed that when i shift gears (especially 1st-4th gear) that the transmissioning is not smooth, even though i am at the correct speeds and try rev-matching. It's like the engine braking is so powerfull, like if there is a huge energy loss to friction that causes an abrupt uneven transmission that feels like when you are accidently going into a lower gear with too much speed, however it still happens at low speeds. And i know this bike is not made for only transmissioning at 2-3k rpm, i should be able to make a smooth transmission at 6k rpm with ease (forexample when going from 3rd to 4th gear).

[@MotoMirius]

You should be able to change gear at all rev ranges with this bike. Either there is a fault with the bike or you have not yet mastered changing gear - this is a skill that needs to be learned. If you are experiencing engine braking mid shift then you are not correctly matching the revs as you change. Gear changes at high revs do need to be done quickly. Good luck with this.

[@surfer-meister1867]

@@MotoMirius See I get what you mean. However I have ridden other 125cc's both commuter cycles and other sports, and haven't experienced engine braking quite like mine have. And it usually only have it when it's cold, and then it gets a little better after 30mins. However I do know how to shift gears (not a pro, but average knowledge). I already know hot many RPM's the engine will run on the next gear when I shift at a given speed, and rev match it, where my worst is still only off with like 10-15% of the right RPM (at most), yet it still tend to feel like there is a lot of friction loss within the engine (or whatever), causing it to engine brake more than what feels natural. And sometimes when I accelerate I can easily slip the gears within 0.5s without feeling engine breaking, but when I do it slowly (2-3s) (like slowly changing from 4th to 3rd at 35km/h it feels uncomfortable. And I can't even drive in 1st and 2nd gear while slipping the gas, then it engine-breaks so damn hard even tho it is below 20km/h. I have to note, I bought this specific motorcycle with 6500km on it, and haven't tried a factory new one. So without 'knowing' how it should feel like, I can say it still doesn't feel right. But I can definitely ride it, just VERY annoying in traffic jam at low speed or roundabouts, since the sudden change in gear causes immediate engine braking

[@surfer-meister1867]

@@MotoMirius If you read that long @ss reply I just wrote, please leave some advice. I don't know a lot about the bike's engine or if there is some simple service to be done in order to fix/better the issue

[@Danbrown504]

Trying to get my exhaust off but its seized into the engine. Any tips for removing? all bolts are out but it wont shift. tried 3 diff penetrating oils and "freeze off spray" with no luck

[@MotoMirius]

Unfortunately this is quite common. It will be stuck in place with the gasket, rust and built up carbon. You can try using the exhaust and heat to try and lever it out but often the exhaust will break off and you end up carefully chiselling the remains out but being very careful not to damage the soft aluminium of the engine. Good luck!

[@Danbrown504]

3 weeks later and its still stuck in place lol id cut it off but there quite expensive to replace @@MotoMirius

[@MotoMirius]

And stuck it will stay until you apply enough force to remove it. Not at all unusual to end up cutting it off then chiseling the pipe remains carefully out of the cylinder head. @@Danbrown504

Good tutorial👍 I have a Gsx-s 125 myself. I am looking for an exhaust system, what are your thoughts on black widow?

[@MotoMirius]

Black widow seem to have a good reputation. Should be ok but it’s hard to judge from online what any exhaust really sounds like. Skäl. David

[@jakobkonradsen1248]

Hi, Moto Mirius. I am thinking about buying a tall tidy for my Suzuki gsx-s 125. I can’t find any good videos online on how to install one. It would be very helpfull if you could make a video on how to install one. Thanks!

[@MotoMirius]

@hoops 1888 Fuel system always has the ability to make some adjustments because this is normal in riding - altitude, temperature etc. It isn't possible to say 100% because some people live in more extreme places for an engine. Check the installation instructions - one big reason why using a mainstream supplier over a cheap supplier helps. Generally, if it has all the baffles in and isn't much louder then you are fine, once you start removing baffles or you buy a loud system then you start taking risks.

[@Shortbikerblondie]

Cool video 👍🙂

@@MotoMirius thanks for the link, sorry about that, after I posted the comment I saw the title and it had the name of the exhaust, I felt like such an idiot 😂😅

[@vetle9132]

When you install a new system, do you have to adjust anything like gas intake or something?

[@MotoMirius]

It depends what system you fit - read the instructions before you buy because any reputable manufacturer will tell you. This one with all baffles fitted does not need any changes, but of course once you start removing baffles to make it louder then you start to reach a point where you will need to fit a fuelling device.

[@vetle9132]

@@MotoMirius Ok Thanks!

[@JDMz]

With this exhaust. No it's just plug and play. Just use the paste that comes with it. Let it idle for 10 to 15 minutes. Then go for a test ride using the gears vary the rev range. Let it cool down and re inspect. Job done.

[@jikseri5065]

Hey! I have the gsx-r125, did you need to put a power commander or something similar so it won't run too lean? I'm looking at buying this exhaust and I was wondering if I need to adjust my air/fuel ratio because this is a full exhaust, I would keep all of the baffles in.

[@MotoMirius]

If you are running with all baffles it should run on the stock map. Skäl. David

Changing the system can result in an engine light, but often will go away as the ECU updates the map.

hello! i have the same exhaust but the muffler inside seems to be loose, so it makes a rattling noise, any help?

If it is rattling inside the muffler then you would need to take the muffler apart to fix it.

Do I need to tune it ?

[@MotoMirius]

Direct from the manufacturer, no. If you start to remove the baffles or do other work on the bike you might need to. Typically removing one baffle is OK

[@ziggecigarr6150]

Can you buy a slip on instead of full system?

[@MotoMirius]

If you were willing to cut up the existing system you could probably fit a slip on to it, but the stock system is one piece. Skäl. David

[@MotoMirius]

@James KP As I said, there are none. You would need to cut off your existing end can and then find a slip on the right size to fit the pipe and make up brackets to hold it in place

[@demonpython7217]

Your going to have to remap the bike dont you

Depends on the exhaust fitted.

Is this legal
