2019 Honda Monkey MNNTHBX Mtake Intake System Install

[@eastcoastish]

Thanks for the video, it helped me with my install - I think you missed a step though for mounting the breather filter - the extra plastic washer looks like it's for the hole on the breather filter to make it flush so that you can mount it on the 10mm bolt hole on the other side of the frame like the picture on the MNNTHBX site.

[@John5XR]

You’re 110% correct about the breather not being in the right spot, and the spacer being for it and not the bracket like I used it for. I wanted my breather hidden and is why I kept it that way, but the way MNNTHBX designed it, is how you say. Thanks for pointing this out!

I'm from Greece and i'm proud for the Greek DNA air filters

[@michaeljkasnter]

I just had mine installed along with the Yosi-RS3 and a Power Commander 5, had my Monkey Dino tuned by a professional. Bike sounds phenomenal , intake noise is cool. I notice a boost of mid range torque, well worth the money!!! That stock air nut sack has to go !!

[@John5XR]

That’s awesome! Where did your HP numbers end up? That’s basically the same mods as mine

[@MillersMotorcycles4994]

A perfect video to help me or anyone with the install and nice touch with the service manual. Ordering that will deff help, thank you John! Just waiting for the kit to arrive! Another perk of getting this kit is how it makes it so much easier to clean the bike.

[@John5XR]

Thanks Joseph! I appreciate the compliments! The service manual is a great tool, the most important in my opinion. I've learned a lot from just browsing it and uncovered some cool things about the bike (my Grom too). I think you'll love the kit, it's more impressive in person just like the Monkey itself

[@nspacetime]

I think it looks far better now. Hate that big black box. May have to shop around for the same. Thx again!

[@John5XR]

Me too! Only one place to get it, MNNTHBX.com!

[@janjoppe1]

John, Greetings from the Netherlands and a great thank you for this great video, really helped me a lot, had it installed with your virtual help in no time!! Next step is the Bazzaz ZFi EFI Controller, with only my Akrapovic my Monkey runs 64MPH on GPS on a flat road with no wind, hope to get some more after everything is installed...

[@John5XR]

Hi Jan! Thanks for watching and commenting, glad it helped! I found the Bazzaz added some top-speed on my bike in support of the intake and exhaust, and more importantly to me, will support future mods or allow me to fine tune the settings.

[@janjoppe1]

@@John5XR Did a test run this morning, runs 67 mph now. with Akra slip-on.... the rest of the Akra will come this week. Also ordered another camshaft,

Do you use the K&N filter oil and cleaner to service your air filter?

Great video my friend.. Used your other video to change the shifter and the sproket to a 14 teeth.. Thanks 👍😊

[@Rasputin_Fusher]

Hi John, Does this Air filter get rusty? I have Takegawa air filter, but it gets rusty very quickly, now I regret the purchase. Thanks

[@John5XR]

Not at all! I’ve had it in some pretty nasty stuff too

[@Nochillatall]

Adding my thanks John - all of your videos have been super helpful, or just fun to watch y’all mobbing around. You do a great job stepping through details. mnntbx can thank you for another intake and exhaust sale! Quick question - what brand is that yellow and black nut driver you use with the ratchet attached? That thing is awesome. Btw I ended up wrecking that screw on the band clamp on the stock intake..the one you change screwdrivers on. That thing is really in there. Thanks again and keep up the great video work!

[@janjoppe1]

same problem with the clamp here, had to cut the rubber hose...

[@John5XR]

Man, sorry I missed this! The nutdriver and ratchet are Westwood brand, but I'm seen this setup with other brands too. Thanks for watching!

[@digitallove421]

With a full exhaust and high flow intake. Did you tune/flash the motor with anything? power vision? Power commander?

[@John5XR]

Yes! I chose the Bazzaz system and it added the right amount of fuel needed to correct the air/fuel ratio after the intake. With intake and exhaust, there was no power gain without adding fuel

[@mikeherber8358]

@@John5XR just changing the intake to mmmnbx brand running stock exhaust do i need to do any fuel/air ratio things

[@mebobbygillis]

I like the way the existing filter looks more.

[@John5XR]

The big box?! Never thought I’d hear that said! Especially over this, it’s a great looking piece

[@mebobbygillis]

@@John5XR the replacement leaves too much empty space. The bike looks unfinished to me.

[@John5XR]

That’s fair, I can see your point.

Someone will make something to cover those items. It's only a matter of time.

[@baldilocks1914]

That Guy my thoughts exactly! But another wonderfully done video.

[@yvonnecarpenter2957]

Very helpful video, thank you! You made it look like a toddler could it, lol! And what a difference it makes not to have that huge black box “in your face”!

[@John5XR]

I do have a toddler that thinks he can do it! Thanks for that, I’m glad the video was easy to follow 🙏

[@rustwag32]

On a carburerated bike when you replace the mufflers and airbox, it's standard procedure to re-jet the carbs... What did you have to do, or adjust with this upgrade. Was there any remapping or electronic adjustments to make it run correctly ?

[@John5XR]

You are correct sir, and it’s the same with a fuel injected bike as well. To add more fuel, I installed a Bazzaz Z-FI fuel controller, which you can see in my Monkey build video library.

[@bluevalkyrie2517]

WARNING! 16:15 This larger tube is NOT a gas tank vent. It is the refueling overflow tube. When your refueling and the tank is over filled or if gas is spilled around the cap area it drains down a hole next to the opening and down this tube instead of over the sides of the tank. This tube is held in place by a split tube on the left side of the stock air box so that spilled fuel can drip to the ground. It does not go into the inside of the air box. This overflow tube should be routed down the side of the cylinder toward the ground. The fuel tank vent tube goes to the evap. can system and is not effected by this intake change. Not allowing this overflow tube to drain to the ground could be a FIRE HAZARD.

[@cwelliver1985]

Prove it

[@bluevalkyrie2517]

@@cwelliver1985 I know it's deceptive, even Honda's service manual misidentified the tube on one page and then correctly describes it as a drain tube in another section.

[@mikeherber8358]

I want to put that intake on my monkey and will be using stock exhaust my question is do i need to do any remapping fuel changes etc so not to lean out the engine, Appreciate your help

[@John5XR]

Nope! Adding the intake and stock exhaust will be perfectly fine with the stock ecu. It’ll sound great too! Check out my intake sound video from this past summer to hear it

[@mikeherber8358]

Thank you

[@burz]

Can you possibly post the part number for the Honda service manual. I cannot find them online so I assume I am religated to my local dealer to grab one. Also what did you pay for the manual?

[@burz]

@@John5XR Awesome thanks. Also a side note - the airbox will come out easier if you remove the front cover first as far as I have seen, vs. removing it complete as the fender will get in the way more. My kit is on order, I think I will be wrapping the silicon tube in some kind of race tape to hide it away more and then possibly look at making some custom side covers to hide some of the less amazing looking hoses that the Air box would normally cover up. I am going to link to this video on my site as a how two one I get it installed and do the site post. So maybe a few more views for you.

[@John5XR]

I can see where that makes sense. For this video I was following the manual, so I just yanked it out! I like the look of the off-white intake because it matches the bike well, but can see where it stands out. Enjoy!

John, Greetings from London UK. Thank you SO much for helping us with these videos. I have a black Monkey which I love. I'm going to do the same mods that you are doing. Do you have an address for the Company which supplies the air intake & the shocks please ? Kindest regards, Alan

[@John5XR]

Love hearing this Alan! I get everything from MNNTHBX (mnnthbx.com/product-category/honda/monkey-125/). Great company and they’ve helped me along the way to understand more about this intake and how to optimize it with tuning, which I’ll be doing next. If they don’t ship internationally, I can help you with it as I run a MX-5 parts company and we ship internationally. Cheers!

[@Big_Boulders]

I think sensor being mounted externally is a design flaw, it is not measuring the true air temp going through the intake pipe

[@John5XR]

I’m not in love with the sensor being externally mounted either, but also don’t feel there is a difference in temp between outside the pipe and inside. The intake is drawing in the same outside air as the sensor is reading

[@SK-lr2vs]

Thanks for the instructions. Much appreciated.

[@lukasvaughn2082]

I followed the steps but when I started it after the install it revs up but won’t dev back down… did I miss something?

[@John5XR]

Sounds like something with the throttle cable

[@John5XR]

ah, I bet you're anxious to keep it off this time!

[@funnyfudgeman16]

Does your bike have a fuel controller? These bikes can run lean with an intake and exhaust. Also be sure to oil the filter for an extra layer of protection against dust and debris. I also wouldn’t recommend riding through water or in the rain because as I’m sure you know water and engines don’t mix 😂. Great video as always

[@John5XR]

Yes sir! Check out my Bazzaz video to see the fuel controller I am using. And yes, the exposed filter is more maintenance than the OEM box, but it faired quite well during two days of rainy riding at the Barber Small Bore. I was impressed! Maybe I’ll get an outerwears pre-filter for it for my dirt riding

[@funnyfudgeman16]

John5XR Excellent. I will check out that video. Ride safe!

[@rorbber]

How does the filter perform in Heavy rain

[@John5XR]

I'd suggest adding the optional Outerwears pre-filter, which makes it waterproof. I've never had an issue as long as I've had the Outerwears pre-filter on it.

[@cctvspystore]

Open Air....bellissimo

[@jreid641]

Can I run the stock ecm with this intake and non stock exhaust system?

[@John5XR]

yes, but the fuel mixture will be even more lean and you'll lose power until you add more fuel via the ecm reprogram

I just payed a deposit for my Monkey, I will make a custom intake for mine.. I want an off the shelf one but this looks cheep and crappy to me.

[@John5XR]

It’s definitely not cheap and crappy, and the Monkey is tough to work with on intakes as there is A LOT going on beneath that tank for the fuel injection/throttle body system. It’d be a great challenge to build a tight fitting intake, and this intake is about as tight and tucked in as I can see it getting. Good luck, I’m curious to see what you come up with!

And whats the whole point of doing this? Does it go to 75 mPh now? ))

Not yet! Here in rural Florida the roads are generally fast, at or above 50mph, unlike a city, so I’d like to get the bike capable of a little higher top speed in case I end up on a fast road

@@John5XR I want to make it my main commuter but we have hills and 55mph limit and ppl usually go 65 or so. I wish this little thing was a little faster.

[@John5XR]

Exactly! It won’t go 75 now, but I hope to get closer to 70 with the Bazzaz tuner I am installing next

[@ridelive6249]

@@John5XR Do you think it can put too much pressure on that small engine and wear it out prematurely?

[@John5XR]

It won't add power in great measure enough to cause an issue. The nature of intakes are to achieve more airflow, which will lean the air/fuel mixture and with that, might cause the engine to run hotter (not much). The only chance for premature wear would be piston rings, and it would take YEARS at that. I have 1970 Trail 70's with original pistons and rings that have had ill carb tuning for the last 30-years and they still run fine. Also, this isn't a death sentence for a Monkey. I replaced the piston and rings on my Grom for less than $75. The work took less than an hour.
