Honda Navi (Air/fuel throttle stop screw Welch/freeze plug removal

[@petev.9357]

For a free D shaped tool for the pilot screw get a spent .22 LR or magnum case and dent one side a little. Once you remove the screw you can slot it for a screw driver.

[@jeffmartin6174]

What's the best way to dent the .22 shell without flattening the other side? It's a great hack.

[@haroldgomez7330]

Great video! I tried to mix the air and gasoline in the 2023 Honda NAVI, but the carburetor has a plug on the air valve that I cannot change because it is closed.

[@leokyla67]

Thanks for posting your video. I am having the very same issue on my 2013 Honda TRX 250X quad. Welch plug in the way of the mixing screw on Keihin carb. This might be a stupid question but I was curious why you recommended left fluted drill bits and used the drill in reverse? Aren't the Welch plugs pressed in? I started drilling my Welch plug out and it started spinning in the bore. Dremel tool to the rescue.....

[@jasonenglish458]

Same problem running really rich here in CA. 33 miles and burned 1/2 tank of gas. Stalls after 5 miles, wont restart till the next day. I have no mechanical skills. Maybe they had to do adjustments to carb for CA compliance and it's not working out well on 1st deliveries? Thanks for the tutorial

[@rideordie6886]

Yes I’m getting 60 miles to a tank right now. I finally got a chance to take it out but now it’s crappy out again so I’ll have to wait to get this thing dialed in, I’m going to change the jets. I have a 90 main jet in, if I can’t dial the carb in better with the richness I’m going to put the 88 main jet in and see if that helps.

[@SCMOTO]

Great video. I wish I had filmed removing mine. Have had a ton of people ask how. Gonna send them your way.

[@kilofrinzztv2370]

So the only reason to use a left handed bit is to get shavings out? Need to do this tomorrow and dont have those on hand just wanna make sure im not missing anything

[@mazenogbi5717]

Part 2 please cuz I have the same problem and I need to adjust it

[@mazenogbi5717]

And some times it dies when I turn the throttle real fast

[@rideordie6886]

hey Mazen! Yes part 2 will be coming... Thanks for watching.

[@rideordie6886]

@@mazenogbi5717 yes its running rich, if it was sputtering it would be running lean sounds like you have a project

Another great Navi video! I'm hoping someone comes out with an aftermarket carb that will have the screw accesible.

How are you going to tune it?? I don’t see a screw just a flat brass piece. Harley’s have a screw under there. Is there a tool

[@rideordie6886]

There’s another video of how I tuned mine Navi…

[@lordkimjungunbombmiggameri9490]

Whats the purpose of this?

[@sammisdaddy]

Any particular reason to use the left hand bits if you are not extracting?

[@rideordie6886]

It drills out instead of in If that makes sense

[@kyleholmes6391]

Serious question. Why didn't you take it back to the dealer? It should be under warranty?

[@rideordie6886]

My Navi has upgraded parts to it and would have to be tuned anyways so I wasn’t to worried about it.

[@kyleholmes6391]

@@rideordie6886 Thanks, for replying. My Navi is backfiring really bad when decelerating. I called the dealer & they said to bring it in.

[@rideordie6886]

@@kyleholmes6391 yes it’s definitely get either lean or rich. When you get it back from the dealer can you let me know how it went and what they did as I’m curious on your out come. And thank you for watch and if you haven’t already subscribed much appreciated Kyle

[@kyleholmes6391]

So the dealer re jetted the carb for high altitude. They also adjusted the air/fuel mixture. The backfiring is minimal now. Fuel economy is not as good as I hoped....60 mpg.

[@mkichu]

Why du have to drill ???? Pls... 🙏

[@rideordie6886]

To access your air/fuel screw for adjusting, Navi to run proper

[@jeffmartin6174]

RideorDie, I followed your video very very carefully this afternoon and successfully removed the welch plug and then was able to remove the air/fuel sceew with a .22 shell and Dremel a slot in it for future adjustments. What I totally forgot was to count the amount of turns and now don't know what factory setting was. Did you note what the af screw was set at from factory? Thanks again. There is no way I could have done this without your help.

[@rideordie6886]

Hey Jeff! That’s awesome and I’m glade it helped. I was thinking of doing a tuning video, but I think with how advanced it is for most of the viewers I didn’t think it was a good idea? What is your elevation where your live?

[@jeffmartin6174]

@RideorDie I'm about an hour and a half east of Toronto, so around 250 feet above sea level. I should be receiving my MNNTHBX intake kit on Monday, so looking forward to getting those jets in. I may go straight to the 90 main like you did and get a muffler shop to weld/fab something onto the stock pipe. I can't imagine holding out for a full system with larger header pipe would produce much/any more power than the stock with an open muffler. I would absolutely be interested in a tuner video. Have been noting your info on an O2 sensor. Don't know anything about that, but curious. My main ride is a '20 KTM Duke 790 so don't want to break the bank on my little Navi.

[@rideordie6886]

@@jeffmartin6174 I’m thinking these Navis are set up rich from the Honda so they can get them thru the dealership with no problems? I don’t know but that’s my thought. Also my guy that does exhaust said having the factory header pipe into the aftermarket muffler will push the gas’s out faster then jumping to a bigger pipe, he’s been in the custom fab exhaust world for 40 years. Also I don’t have a o2 sensor I’m going off sound and throttle response but mostly the multimeter Runleader is giving me my rpm reading… I have mine tuned I’m at 922 above sea level here in Minnesota. What I can do when your set up to turn some screws I can count mine and tell you how many turns mines at? But I would get an rpm reader/gauge, harbor freight has a tool if you didn’t want to have a gauge but the Runleader is probably cheaper

[@jeffmartin6174]

@RideorDie Great thank you. I just ordered my Runleader and will be shopping for a pipe. Did you say there were two step downs? 1/2 to 1 then 1 to 1 1/2?

[@mattpittman8307]

Thanks for watching Navian, I will be doing a second video to this on how to tune your your carburetor on your Navi…

where's the tuning video ?

[@rideordie6886]

Hey mizzmizz693! Thank you for watching and if you haven’t already thanks for subscribing. What would you know on tuning. You will need a tachometer tool or you will need to have a tach hooked up to your Navi so we can get your rpm set right… I have a Runleader installed on mine there are many different tips of tachometer the purchase. That’s your first step second is Welch plug and once you get to that point I will do a video;)

No don't do it like that.... That's not how they teach you at MMI. You just use a 3/16 or 1/8 drill bit... Lightly, force ... a coarse thread screw in the hole.... And use the slide hammer technique. ,. To pull the plug out....

Just upgrade the carb, the stock is terrible for this bike.

Hi ken. Thank for watching. What makes it junk? I have it dialed in no that the air/fuel screw is open for adjustment. Runs well no more running rich and head light tail light flicker has minimal now at idle. I’m at 1700 rpm to 1720 rpm. I’m sure there is other upgrades to the carb to make it better but this scooter is for the kids and I’m definitely happy with the air/fuel screw being acceptable now. But I would like to know on your input?
