- CanyonChasers Question: Is it important to have your motorcycle tuned when you add a slip-on exhaust system and/or a free-flow air filter to my motorcycle, or is it only necessary to have a bike dyno-tuned when I fit a full exhaust system?

Wow I'm flattered! I really appreciate the information coming from your channel I find it highly professional and accurate! Note taken about the dyno tune! Thanks!
I dunno about cars, but motorcycles are tuned from the factory to meet emissions requirements. They are not tuned for performance or fuel economy. That means, they are typically set up lean from the factory. By adding high-flow air filters or freer flowing exhaust pipes, without compensating for those changes, you are making the bike run more lean than it already is. Most - if not all - fuel injected bikes do a good job of compensating for one thing or another, but not both. So, if you add only an air filter, you likely won't have to do anything with your fueling. If you add only a slip-on, you likely won't have to do anything with your fueling. However, if you add an air filter and a slip-on, you're probably going to have to retune your bike or you risk a meltdown from running too hot from an overly lean condition.
All that being said, even a bone stock bike can benefit from a tune, one way or another.
i know this is a noob question. but for carbureted motorcycle do i just adjust the air and fuel mixture by screw? no need for a dyno?
Thanks for explaining! What would you do if you installed a full exhaust and an air filter ? A ecu flash or a Dyno tune?
@@happyraider815 you would buy a different "jet kit" or what is called "rejetting" the carbs
@@Champion2Manager you can adjust your ecu without a dyno. The dyno is important because no 2 bikes r the same, and a dyno is the only real way to squeeze everything out of your bike. An "off the shelf" ecu or fuel map will help and be better than stock, but a dyno will allow even more fine tuning for that specific bike on the dyno.
My *R7* is in for tuning tomorrow..
I wasn’t sure exactly what I was looking for until you said “wanting the bike to run as good as possible rather than chasing BHP & Tq” 👏🏽👏🏽👏🏽
this totally explains why my bike kinda sounds shitty after adding the graves slipon to my 2015 636 it does exactly what he said
Omg this is what happen to me today and scared the crap out of me. Found it so quick thanks to you guys !!
Very good information here! I was about to do an ECU flash, but I guess now that it’s best to do a Dynotune for better fueling and throttle response.
An ECU flash would effectively do the same thing for you. The thing is we need to retune the FI system to account for different amounts of air coming and going through the engine.
Thanks for the info, time to look up a tuning facility.
But it's best to do it after an exhaust and air filter..why waste money on 2 dyno tunes?
Often heard people said why get a fuel controller when your bike is running with a stock exhaust. I installed one on my Z1000 with stock exhaust and hell yes i felt the difference in power immediately, because most doesnt know how the factory tune their bikes according to regulations set by whoever.
Exactly! The manufacturer has to meet localized EPA standards, which will not be the optimum air/fuel ratio for your exact location, your exact fuel and your riding style. Just like in the old days, the very first thing discerning riders did was purchase a Jet-Kit. Modern Fi is certainly more adaptable that carbs, but they can always be made better. :)
really appreciate your videos!
So what is the purpose of the 02 sensor in the exhaust? Isn't the sensor responsible for how lean or rich the fuel is?
boxz1984 this guy is full of shit. Next if u add air to your tires going to need a dyno tune
Thumbs up. Thank you for this vid.
Very useful information thanks. I am not too much experienced with powerful motorbikes. Recently bought a brand new Yamaha FZ-10 2017 model. 3000 miles done so far, Quite enjoying the stock version. I do not do track days or push the bike to its limit.
I really wish if my bike is bit more louder. When I say louder heavy bass beat. I am planning to go for the American made value for money option Delkevic exhaust with middle pipe. That makes the bike lot cleaner IMO.
From the comments and answers I understand I have to do the following in the same sequence.
1. Get the exhaust installed myself
2. Install a better air filter like K&N.
3 take my bike to flash my ECU and the dyno tuned.
4 not planning to install any power commander.
Question: I live in Tennessee, with the above set up done, does that mean I have to revert back to stock condition before smoke test while renewing the plate ?
Please advise.
It depends on how rigorous local emissions testing is in your area. Legally, yes. But you may want to contact your local race club/motorcycle group to see what they say as there are so many variables here.
Smoke test? I'm next to deal's gap (dragon)..... you must be in the wrong part of tennessee lol, need to be in Maryville.😁
Thought it was illegal in most countries for engine manufacturers to lean out the engine in the specific spot where emissions testing is being done?
Have you seen the VW episode of dirty money on Netflix. It appears all car manufacturers do what they can to pass the tests
Why doesn't the O2 sensors compensate and adjust the fuel trim when they see the bike going too lean? That's what cars do...O2 sensor sees too lean at a given RPM and tells the injectors to add more fuel..bring the level to where it should be. If that's the case why don't people get reflashes on cars when they add an intake and exhaust?
Motorcycle systems are simpler, and motorcycle engines are more sensitive because they run in a higher state of tune. The O2 sensor basically just operates within the parameters of a pre loaded map based of a certain fuel type, temperature, humidity, and a certain elevation. This is why a lot of European bikes struggle when they come to the US; because the base-map was built using European fuels (without Ethanol).
@@CanyonChasers some ecu are self adjusting aren't they?
Would removing the O2 sensors and installing fuel dongles be enough, when adding a road legal slip-on and a high flow K&N air filter ?
I still don't quite get what a lean spot is
Theguyunderyourbed are you being sarcastic?
What’s the difference in flash and remapped
Some good info.
So he mentioned with changing air intake yes u should because it changes the airflow coming in the engine. But what if its JUST THE EXHAUST WITH STOCK AIR CLEANER/ INTAKE??? Would u still need to dyno tune it since all u did was change the airflow going out but not change the airflow coming in
The faster the air goes out, the more air that can come in.
Looking at a Honda CB500X, it is A2 friendly, but after a dyno tune, do I need to restrict it, will it say the increased power on its log book or other papers ?
The problem is dyno tune is expensive
Pedro Santos and unnecessary. Hence the slip on for $129.95. It’s a piece of metal man.
@@maxell6782 👍👍👍
You can get cheaper dyno tuners but you get what you pay for. I know I'd rather spend more to have it done correctly than another dyno tuner that's cheap and will make your bike run even more shitter
Is it mandatory to have a fuel controller once a full system and high flow air filter is installed?
El Profe Depending on your motorcycle you may need a fuel module like a Power Commander, or you may not. Some motorcycles can have the ECU reflashed. Check your motorcycle specific forum for details, or contact your local DynoTuner for information specific to your motorcycle.
+Steven N. Some systems, and some methods allow them to change the air/fuel ratio's. Not all of course; which could be part of your confusion. So it depends on your motorcycle more than anything else. For example, on my personal Multistrada, I can have the ECU reprogrammed to adjust air/fuel ratio's as well as even add cruise control. But on my old SV650, the only way to update the air/fuel ratio's was a piggy-back system like a dyno-jet.
Hi dave,i wondering how we can read dyno graph?how do we know if the AFR isnt in proper tune?how to make throttle respond sensitively?Im from malaysia
So the dyno tune is custom for the location of air density MSL and barometric pressure of that time? Should have a custom map for every season then.
A A ridiculous unless you are a pro racer.
@@zipper978 Do you need to retune for wear?
A A what do you mean wear?
@@zipper978 like, when the rings start to wear and other things wear you should retune for the changes or setup a tune for when it wears this way you can have the right tune between the average of where it is now and it's entire life than set to set the best tune for now then when it gets older the negative performance differences become greater?
A A if you are losing enough compression to need a new tune you have bigger problems my friend.
very good explanation. never really understood what this thing is. question though. in your experience how much power is left unused (in percentage of total improvement) if you are aiming for improved ride feeling? Also am i right to think, that whatever gains you get from remapping, on a stock bike, they would not really make a huge difference in hp numbers?
You can sometimes get as much as 15% improved power based on what the state of tune was where you started. But the key factor is to improve drivability and protect the motor for longevity. But if you measure in lap-times and not just hp/torque numbers, most riders will see an improvement in lap times because a good tune makes the bike easier to ride. The throttle ramps into the power more smoothly and bike will pull strongly in a wider ranger of RPM.
Thanks for the tips. Will keep watching your vids for education purposes :))
I can confirm at least for cars. My STi had an "off the shelf tune". Had pretty bad turbo lag, you could feel the car throw you back after going wide open throttle, and then a few seconds later it throws you back even harder when the boost kicks in. After I got dyno tuned by one of the best in my tri state area, it's much much smoother, the lag isn't as extreme and honestly I have to keep looking down at my boost gauge to see if I'm even getting out of vacuum.
Do you need to change air filter or air intake when installing slip-ons?
Not necessarily. You may want to ask others with your same bike on a forum to find out what others experienced by only doing one and not the other.
OK, so is dyno tuning better than a fuel controller?
Yes. Dyno tuning is the only way to ensure your bike is running correct. However you may need a piggy-back module like a Power Commander depending on your bike.
Does this include on smaller CC bike? I have a CBR150r 2014 and i just recently bought a stainless steel elbow to mid pipe and SC Project canister.
I'm curious too! I have a 2023 CBR150r and wondering if I need a tune for a slip-on exhaust.
Do i need to get a stock motorcycle with CC & bhp as low as 200cc & 25 bhp dyno tuned to make it run better or this only is practical for higher cc bikes??
Got a 2012 Honda cbr 1000rr put on a new slip on took out the old one and now on 3rd and 5th gear starts to cut off like hikes up should I tune the bike or could be something else? I’m in Connecticut too so I don’t know about the elevation shit😂
I got a dyno tune and Hp improved everything improved except the range for gas ⛽️ dropped I went from 255 range to 145
Thats a little unusual. Could it be the bike is so much more fun you are just giving it the beans a lot more frequently?
My 05 Hayabusa dropped mpg considerably after slip-ons and PowerCommander with a dyno tune. It was slightly lean at lower revs stock. In stock form I could get over 50 mpg when needed and averaged 45 mpg touring. After slip ons and dyno tune, I lost about 7 or 8 mpg from what I was getting stock. I only gained less than 10 hp but had a cooler sound ha. So my 5 gallon tank lost around 40 miles in range.
Do you need a power commander to dyno tune the bike although it's just a slip-on?
Traditionally yes. A Power Commander or Bazzaz or something similar. But it seems like anymore, there are more and more alternatives that don't require a piggy-back module. You may want to check forums for your specific bike to learn if a piggy-back module is required in your situation.
How much does it cost for a Dyno Tune?
Should I wait until the break in period is over to get a Dyno tune ? My bike only has 30 miles on it.
Actually the very best way to break in an engine is with a "dyno break-in"
What should I expect to pay for a Dyno tune after adding on Rinehart Racing slip-ons and K&N high air flow filter? The bike is a 2007 Harley Davidson Ultra Classic
It depends on the level of tune, and the quality of the shop. A full, top to bottom race tune may be as much as $400, but a base tune may be as low as $75
Thanks for the info..i think i need to get one..im getting the popping when decelerating and then ultimately stalling at a stop. Thanks again👍👍👍
Rob Rios did you ever get your dyno and if you did !!!! Did it make a difference !!! And if you did was it done at a dealer ship ????
what if dyno tuning is not am option where you live?
A dyno tune will always be your best option, but PowerCommander/Dynojet makes a device called an "AutoTune" that will do a reasonably good job.
take a day and ride to the dyno-guy? :)
if I dyno tune my bike after putting on a slip on custom endcan will I need to do it again when I switch to stock can, also if I take off the custom can solely for mot and put back on after will that effect anything
Technically, you would need to dyno-tune any time you make a change to the bikes intake/exhaust system. However, if it were me, and I just put the OEM can back on for MOT, i'd not get it dyno-tuned since I'd just be putting the aftermarket can back on anyway.

Wonder if it works on 125s?
Please help answer my question I have anyone please.. i have a 2015 yzf-r3 and had the aftermarket m3 slip on it for a year now and never had my bike tuned or under a dyno. I don't want to mess the engine up by not getting one (if it even could), but I havent had any problems at all without having it never tuned up since I installed the slip on. But I kinda don't get the same noise as when I first put the slip on on I guess maybe it always sounded like this and my mind just thinks it sounds different now but should I get a dyno tune up? It cost a lot and don't want to spend money on it if I absolutely don't need it. I'm planning to trade this bike in 6 more months so should I get it tuned or w.e?
I live in Colorado Springs about 7100 feet above sea level. Should I get my stock Indian Scout tuned? Thank you.
A tune never hurts. Here in Salt Lake, I basically get every bike tuned and we're only at 4500 feet.
Hey i have fullsystem exhaust and already tune now i wanna change my slipon do i need to retune it?
Probably not. It shouldn't make that much of a difference.
Is it true newer motorcycle could calibrate itself it your let it run for a period of time after putting a slip-on?
Yes, to an extent, but it's typically outside of the range of the stock systems. A tune will always be better.
@@CanyonChasers Thank you
Is it problem if i don’t tune the bike after adding exhaust system ?!
It might be. You may be running lean with just an exhaust system, and lean conditions may damage the motor.
Great info, I did an upgrade full line Termignoni on my Multitstrada GT 2014. The bike doing a lot of Backfire. Is the dyno tune should be done to even if the up-map is provided by Ducati ?? i feel that even with the UP-MAp update the bike seems backfiring a lot ( not really great when being in a petrol station). Did the Ducati UP-Map should align the Air/Fuel Ratio on all riding mode or only sport mode. i am switching a lot between the Urban mode to to touring mode moving to 100 HP to 150HP low. Is their any way on the Multistrada to double check that Map is properly updated. Thank you in advance mate for you answer i really try to understand how the MTS upgrade work. ( just for Info the Baffle has been removed from the slip on, is the UP-Map is set with baffle on or should have a different map for baffle out ? )
pen tux It sounds to me like the map didn't get updated to your ECU. I'm not super familiar with how the ECU's work on the new Ducati's. But, if the ECU was switched to the new map, you shouldn't be having any problems like that. So I'd start there first.
Hello ..i have a question.. i have a 09 zx10 whit power commander. K&n air filter smaller sprocket and a scorpion slip on..i want my bike to be faster..do I go for more horses or fastes response?..
Get it properly tuned - but it won't be much faster. Then buy lighter wheels, it'll be a bit faster. Then have your motor rebuilt with lots of very expensive parts and by a quality race engine builder like Randy at www.themotostation.com
what if u got a full system exhaust and did't get it tuned.. whats the worst that could happen?
You'll run extremely lean, and burn a hole through the top of your piston.
@@CanyonChasers thanks mate
I was thinking of getting the firebrand exhaust tip for my 2015 and new to the bike world, so can i just add this without doing a tune?
By tip do you mean slip-on? Then yes, you should retune the bike.
Question, I am thinking about installing Akrapovic headers and a Leovince LV slip-on on my Kawasaki Z900. According to the Akrapovic website no remapping is required ut is recommended to gain the full benefit of the headers i.e. HP, torque. I'm not necessarily worried so much about power gains as I am doing it purely for sound and I just want to make sure that I don't damage my engine. Thanks..
Most of us are not necessairly looking for the most power, but a pipe _with_ a tune can make the bike run worlds better. Smoother off the bottom, more linear power delivery and in many case, you will see an improvement in mileage as well.
Hey man i just bought a z900 with an sc project slip on. Im reasearching weather to decat my bike without tuning it. Did you end up getting the system? And was it worth it?
@@Zeryyn I ended up using the Leo Vince LV pro with Akrapovic headers though I had to do a little modification to make them fit together. Doing that swap shaved off 20 lbs from the bike. Still running the O2 sensor. The cat, bread box, etc is gone. I just need to do the block off plates and a get a tune on the ECU eventually. Love the sound of it. SC project makes some great exhaust sounds once you get headers on it. Slip on doesn't do much for sound but it does shave some weight off.
@AZ_PIT_VIPER yeah the slip on is pretty quiet unless i give it some decent gas, so i really want it a bit louder but im just worried that if i end up decattong it and not tuning it that i end up making my engine run lean and the bike doesnt do what its supposed to
@@Zeryyn the only thing I can suggest is calling Kawasaki and ask them. They should be able to tell you. If you bought the bike new y I u should have gotten a card for the factory warranty. If you don't have that I can get you their number
hi sir i got a question, i just put on a slip on exhaust for my 2017 honda cbr1000rr and its really jerky down low rev and i feel like its running lean... my question is , getting my bike dynotune to make it run smooth is good enough?? and do i need to get an ecu flash with it??? does the tuner include the power commander add on to get it tune ??? i only use it on the raod 99% and no track. thank you sir
Yes. You need to tune your bike to account for the changes you've made.
@@CanyonChasers thank you sir 😁
do you need a power commander to get your bike tuned or can they reflash the stock computer
Depends on the year and model motorcycle. Some can. Some can not.
what about 2017 victory octane ??
I have a 2018 Yamaha bolt 950 and I will like to add a straight pipe and a new air intake...what will be your best recommendation for me to do the job right? Thank you
I wouldn't do it, honestly. Most modern airboxes are tuned to flow more air faster than no airbox at all. When you cut open an airbox, a lot of times you go backwards. Pod air filters often times work on older, simpler carbureted bikes, but unless you have good information saying otherwise, with modern bikes you usually just make it run worse.
@@CanyonChasers Thanks for the info well appreciated.....so that been said it means that no straight pipe either...keeping my o2 sensor!!!!
@@CanyonChasers Thanks for the info well appreciated.....so that been said it means that no straight pipe either...keeping my o2 sensor!!!!
Well if your goal is to be loud, then throw a straight pipe on it realizing the bike will never run as well. But if you want to make the bike run as well as you can, get a tuned exhaust from a reputable vendor, a free flow air filter, a power commander and a dyno tune. The Bolt only makes 42hp, which isn't a lot. Thats like Ninja 400 territory. In my humble opinion, If your goal is a faster, more powerful bike, then I'd simply purchase a faster, more powerful bike.
@@CanyonChasers Thanks again.....I just want it a little louder.
What does a dyna tuner do exactly? I thought they just gave you information about your bike after running it through a series of tests. Or will they do the adjustments you need as well? I'm new to motorcycles. Recently bought a 75 CB750 that doesn't have the OG exhaust. Trying to figure out how tune it correctly. It runs good, but I want to make sure it's at its most opitmal tuning.
A Dynomometer has a bunch of sniffers that can read the exaust to know if it's rich or lean. So in the case of your CB, one dyno run will tell the tuner that it's running rich of the pilot jet, lean off the needle and really lean off the main jet. So they take the bike apart, change the jets, needle and needle height. Do another run and it says it's good everywhere, but a little rich on the main jet (or whatever), the make one last change and you have a perfectly tuned bike.
Vs doing it yourself, where you make your best guess based on what the bike does at different thottle positions, go out and ride, its worse, so you guess again, take everything apart, make changes, put it back together go for another ride; it's better here, but worse there. Go home take it apart, make changes, put it back together, go for another ride, now its worse where it was better and way worse there and you fouled your spark plugs, so you go home... and so on and so on and so on.
If your bike has FI, the Dyno interfaces with the ECU (or a piggyback system like a Power Commander) makes the changes in real time, and the tuner can see and make adjustments at, like, 100 different points.
How much does a dyno tune cost?
jacob Hellmann $400-$500
Do I need a dyno tune if I had my ecu flashed?
Ideally, yes. But an ECU flash alters the air/fuel ratios without actual data about exactly how your bike is running. An ECU flash is better than not doing anything, but a dyno-tune with an ECU flash is the best option.
Did you get your question answer ed i was taking my 2015 in for a flash tune and see if it makes any difference
Is a dyno tune a 1x thing?
Mostly. If you change the pipe again or make other changes , like move to Denver, you'd probably want another one.
$900 bucks for a dyno tune? Wtf that’s what HD wants for less than two hours of fiddling around with your motorcycle.
Wow!!
This makes me hate the EPA even more.
Yeah, who needs fresh air and clean water anyway?! We all have to die of something, it might as well be lead poisoning or lung cancer!
Buy a cheap ass good sounded Chinese slip on exhaust and tune it 😂
Hi,im planning to modify my exhaust on my fz6r by removing some pipe inside the exhaust,so if i did,do i have to install power commander 5 or just dyno tune without PC5?
Any time you make changes to the intake/exhaust system of an engine, you will need to adjust the air/fuel ratio to accommodate the difference amounts of air that are coming and leaving your motor. Some changes may seem to be really small, but could have a significant impact on how much motor your engine has to work with. An exception may be if you live at high-elevation where there is less air to begin with.
Geoff Ramsey anyone???
I have a Yamaha R6 05 i added a brock’s slip-on exhaust and k&n filter do i need to tune it ?
Yes. You should have it tuned.
BS!!!!!!!
Of course he’s going to tell you that you need to tune your bike with a little processor that cost $500. He’s a representative of a company that makes a lot of money advising you to “be on the safe side” and take measures to guarantee that nothing will never, ever, happen to your bike. Slip ons are a piece of metal slightly altering the sound of your exhaust, seems a bit extreme. You think people are buying a programmer for $500 after buying exhaust on eBay for $129. Give me a break. Ask this question away from a representative to get a reasonable answer.
Very misleading!!!
Road King Glider why?
Do I need a dyno tune if I add air to my tires?
If I put an m4 Street Slayer on my 2023 Ninja 636 RR with a servo buddy do I have to get the bike tuned or is that good enough?
Slip on
