FZ-07 Stock Exhaust Mod, Phase 1 - 3/16" Holes Drilled
Вставка
- Опубліковано 20 бер 2016
- Drilling holes has never been so nerve-racking. But this modification that anybody can do to their stock muffler is simple and effective for a motorcycle, especially at higher elevations. I will be adding an EJK fuel controller to smooth out the motor, revs, powerband, decel, throttling, etc. I will ride with these six 3/16" holes for a week or two and see how I like it and how the bike performs. I may widen those holes slightly to a 5/16 or even 3/8th of an inch for deeper tone and more air flow at this 6,200' elevation.
Just bought a 2017 FZ07 with no stock exhaust cover, and drilled holes in the exhaust. He made the holes a bit larger and a bit closer to that pipe. I haven't heard a stock exhaust on an FZ07 in person, but this bike purrs! If you're looking to get a better sound, but are a little worried about the loudness of aftermarket exhaust, this may be a mod to try first.
Very good video. I appreciate how you stated the camera you used, and the step by step prosses - very thorough and helpful. Haha good work on the exhaust Il be using this vid again!
If I was you, I would go straight to the 5/16 " holes. Ride for a week. Then go up to the 3/8" if you feel. After I've gone to the 3/8", I've enjoyed it the most.
Thanks for recording it. I was wanting to hear it. Not my taste. I prefer the stock sound. But you removed this idea from my plate. I appreciate it.
Hey no problem. Remember, I'm not finished. I'll be doing another video with medium holes and then again with bigger holes. The holes simply make the stock sound have a little higher volume. However there is no wrong doing and go with what YOU enjoy! Keep an eye out for the next video.
+ryde4ever Today after work I bored out the 3/16" holes to 1/4" and the difference is awesome. It's not too loud to piss off the neighbors, but it's holds the audio tune while riding around at all RPM's, whereas with only the 3/16" holes sound like stock when the motor revs higher than 3k or so. I like this MUCH better and will be hesitant to bored farther because it sounds THAT good. I'll combine a few video clips tonight and tomorrow after recording with the shroud installed and upload to my channel. Stay tuned if you're interested!

Holy shit dude that sounds pretty darn good
Ryan Bruneau yeah, if you enjoy a leaky exhaust sound.
Fun-Zone 07...your enjoying!
+don ervin Heck yeah duder!
look forward to hearing the larger ones. As I rewatched this, I got to wondering what that would look like if you left the end pipe exposed and then painted the ugly part with high heat black. Then leave the shroud off.
+ryde4ever When you have music or a Podcast playing from your phone, have you ever tried putting it into a cup or bowl to amplify it? The shroud that covers the exhaust does the same thing. I like it! If I were to leave it off, I would cut off the square mounting brackets for the shroud so it looks smooth. I probably won't do that, though. I like the look of the shroud. However, I did end up painting my shroud a high-heat "aluminum" color and it looks WAY better than that stock tan.
I have recorded and posted the new video of the 6 3/8" holes the other day. Check it out! ua-cam.com/video/aCz1EW9Dez0/v-deo.html
Hi, please tell me, the tip of the exhaust is overheated, I do not want to burn my shoe
did this do anything to change your top end performance?
what company did your flash? how much was it?
What does elevation have to do in regards to airflow in the exhaust ? Would this be more effective at lower elevations ? Or are you simply saying it is easier to get airflow at the higher elevations.. (Is the increased airflow adding to the sound / so technically bikes would be quieter at higher elevations?)
Google and read up on air density at different elevations. The lower the elevation, the more air pressure you have. At higher elevation, the less air pressure you have in the atmosphere. Therefore, any naturally aspirated engine will have more power at lower elevations then higher elevations. As far as engine sound, I imagine that having more air flow through the motor will be louder. I can a test to the fact that after you add a high flow air filter and exhaust system that your motor will have a louder howling sound to it as it sucks in a bunch of air. I actually preferred that sound over the exhaust note.
Hey man, good job. I wanna know about water.. When you wash it or when it's a rainy day, don't you have problem? Water does not accumulated there?? Doesn't enter through the holes??? What did you do???? Thanks.
Good question. I put the shroud (cover) back on after drilling holes which will help keep water out. But with your motor running you shouldn't need to worry about water getting in very much because of the pressure of the air pushing out. Somebody mentioned being concerned about rust, but I'm not too concerned about that because after I park the bike the heat of the muffler will dry everything off pretty well to prevent rust from forming. And even if rust does start, The stock muffler can always get changed out with a new aftermarket. So if you do this, I wouldn't be too worried about water getting in there. Your tailpipe is a lot larger and exposed to the elements then the six small holes are drilled and people don't seem to be worried about that catching water do they?
Hi, I'm here again. So, did you notice something wrong after some days or not? Did you feel your bike more powerful? Some vibration or strange sounds?? Sorry for ask but I intend to do it in my bike. Where does this idea? who taught you do it?
+de TUDO Please ask away - we're here to learn from each other! I've since then expanded the holes to 1/4" from the 3/16" in this video. I have publish a new video with the new holes in that you can watch here (ua-cam.com/video/6wZG-xtf8G0/v-deo.html). In it, I go over the sounds with recordings and cruise around town a bit. I am very happy with the six 1/4" holes. I am having a tough time deciding to make them even bigger at this point. But if I do, I'll go with a next size up on 3 of them and leave the other 3 at 1/4" just to test for a little while.
With the mod, I haven't had any strange sounds beside the change in the exhaust note. The bike runs at a comfortable 172 degrees when riding in normal conditions (3-6 RPM, 6200 feet elevation, 50 degree F air temp, 87 ethanol-free gas, K&N air filter) and the other day I took a ride over a mountain pass that goes higher than 9k feet and back down and then home again. That total distance was 72 miles. The bike had registered 70+mpg!! Remember, I have a windscreen and hand guards, too. So the aero-dynamics may help a bit with that. So far so good. Let me know when you drill holes and how you like it. Good luck! - Scott
What keeps water from accumulating through the regular exhaust pipe?
did you have any problem with water getting into your exhaust after you did this and causing it to rust ?
Hi I'm super late to this show but just bought an FZ-07. Just curious, how far apart did you space the holes? And overall were you content with the 6 holes @ 3/8"? Thank you!
Anna Martin Hey! I don’t know the exact spacing but I don’t think that matters as long as you have them all inside the third chamber area of the muffler. Since this video post, I put on an Akra Ti and would be willing to sell you mine in this video that I already drilled so you have options. $100 + shipping
@@jacksonwholeexperience409 Is that the full exhaust you're selling? I'd be doing it myself and so I'm not sure if I should just try drilling the holes. I don't have a stand to do more detailed work.
Anna Martin Ya it’s the full exhaust. Easy to change and can be done without a stand. Especially since the bike leans away from the exhaust side, making it easier to get to when it’s on the kickstand.
@@jacksonwholeexperience409 Gotcha. I may go ahead and try drilling the holes. Thanks so much for getting back to me so quickly!
@@Annabelle2486 You're welcome! Good luck and let me know if I can help. Feel free to send a direct message. But I think you got this - it's fairly simple. I'd go with the 6 3/8" holes for sure and skip the smaller ones.
I have the 2016 fz. my top speed is now only 120. lost 18 mph with 5 3/8 holes. 3 top 2 bottom. really smoothed out the bike though.
Thanks for reporting that Whitney! One thing you can do to really smooth out your bike and gain that power back, is get a fuel controller like the EJK, Power Commander V, or have your ECU remapped.
I have to call bs on that one. My bike is stock and it stops at 118.
How much do you weigh, fuel type used, elevation riding at, tire pressure.... angle of downhill riding at??? lol
Whitney Wigglesworth only 120? lol
lol smh fuckin trolls
Hey guys, just a heads up that I've changed the name of the Channel from Teton Riders to Scott's Adeventures. I'm Scott, some call me Scotty. I am doing this because I don't want to be limited to ONLY uploading motorcycle videos. I have more videos of other fun adventures like ice fishing, boating, elk and deer hunting, hiking and other ways of exploring around here in Jackson Hole, Wyoming. I hope you enjoy!
BIG Time Adventures Hey man I just did this to my bike and now it's not starting, any idea why?
Uh oh. I don't think drilling the holes has anything to do with your bike not starting. I've done extensive research and haven't heard of anybody having that problem. I would go through all of the typical and easy troubleshooting - make sure battery is connected and charged, key turned on, fuel, etc. Does it turn on and turn over when trying to start?
Did you ever get your bike to start?
Great
Thanks for watching.
Hey I did this to my bike, and now it's not starting, any idea what happened?
Did you happen to get my reply yesterday? Did you find a way to get the bike started yet?
lol doesn't make sense bud
How do you drill holes in your exhaust and then your bike doesn't start
one would think drilling one large hole would sound better then many small ones
the bike lost hp if i do it? i read it in others page
I haven't noticed a HP loss but I don't race and the bike has plenty of power for me anyway.
Make sure to check out the 2nd video of this series here: ua-cam.com/video/6wZG-xtf8G0/v-deo.html
How did you get the metal bits out?
Ed Kumar The metal shavings just blow out after a few revs.
Ed Kumar
does this void the warranty ?
more than likely
Thanks for the concern. I knew I was going to be getting an aftermarket exhaust at a later date and plan to keep the bike for a long time. If it does void the warranty, there are plenty of stock exhausts out there you can purchase for very cheap or some may even send you their's for free, you may just have to pay for shipping. But as of last Spring, I have installed the Akropovic Titanium full system and it's amazing. Drilling holes works as a temporary solution, but I suggest saving for a "real" setup, get the ECU flashed, etc.
Yes.
Can this ruin or damage your engine?
Naw... You're fine. It would help to add a fuel controller and keep checking up on your spark plugs. But others haven't reported anything going wrong yet.
I think with FI (fuel injected) bikes, the computer automatically adjusts for minor deviations, so with these small mods, the bike should still be fine. Only drastic changes would cause problems... I think.
Allowing exhaust gas to escape from two different places means that the bike now has two different backpressures.
Back pressure myth that exists as much as the dragons ..... stop with that shit
