A 99 honda magna has 4 carburetors. Is this possible on 4 carbs? Can u get to all 4 plugs?
Sounds like it's starving for air
Good looking bike but I'm not a fan of those style pipes. They make nearly every bike no matter what it is sound like a 250 rebel
Sounds like new.
As a long-time mechanic it was a pleasure to watch a much younger mechanic work his magic. The video was well explained and thorough. Thanks for sharing your knowledge with others.
Tubby Greyed Thank you for the encouragement/compliments Brother. Speaking the language of fellow riders and techs allows me to bring more value to viewers. 🤙
Tubby: My words sir!
Love your presentation...by far the best explanation of the way the machine works i have ever heard.I recently acquired a 750 shadow spirit and am hungry for advice.This was spot-on advice for me...Thank You!!
Kool guy man yes great video
Great vid, you explain the adjustments well. The vid can help people who need to get their bike running correctly. Thanks. Subscribed.
Young man I've been in motorcycle business half my life and you remind me of just a small few that has the enjoyment from performing such a simple operation for everyone to understand like a pro. No music no clattering on about how your day went with your dog and you got a flat tire on the way home just straight to hey pay attention grasshopper pause the video any section of the way if you get lost you're right there with us thank you your career is for us to enjoy the training thank you
Thanks for having the balls to try imitating the engine sound. It actually helped understanding. ❤️
It’s a big thing music people do too with certain sounds 😉🤷♂️

Cody, Just applied your video Deceleration Backfire: Tuning your carburetor. I have the same exact 2003 Honda VT750 you did the video on... It took care of the problem and actually sounds great. I just want to thank you for taking the time and posting it. I followed it to the T and all went well. Thanks again. John
John Masell Hey John, so glad that you were able to apply this video directly to your own bike! It is very satisfying and encouraging to hear this!
Cheers brother!
Just wanted you to know, I did take your advise seriously the other day about having screws turned out to far. So today... I took both Pilot screws and turn them both in till I could feel them seat. Did that two times ever so lightly. Then backed each screw out 3 1/2 turns. With cold start I pulled choke out and bike started right up running nice and smooth at fast idle. Pushed choke all the way back in. Motor idled back down running smoothly. Then turned idle screw down, went for a short ride decelerating in first gear and guest what? No more back fire!! Yea I feel so blessed right now. Thank you soooooo much!
+JBHobbyist That’s what I’m talking about man!!! Nice job 🤙
Im a master HVAC mechanic and I can tell you, This Dude is a really good mechanic! Take note.
Im not trying to be rude im actually curious what is an HVAC mechanic.

@@larryclarke7793 oh ok cool. thanks
cool, tell me more about how gasoline engines are similar to air conditioning again?
@@keeganlangford5580 Well, sarcastically, I'd say "mechanical" ! ! ! !
Good stage presence and "flow" to the video with no wasted moves. Clearly visible view on each part of the procedure with accurate and concise explanations and even a little theory behind it all. This video is a solid 10 on the Richter scale. I already knew it all and worked at a couple of shops in the past actually. . I watched it because I'm planning to do a TH-cam demonstration myself.....if I can do one 1/2 as good as he did on this one, I'll consider it an unmitigated success!!
That means a lot man thank you!
i owe you an adult drink mixture or 2 for all the knowledge you've shared, and time, money and sanity you've saved me
Hey Cody, boy am I glad I found this video. I bet you saved me a bunch of money! I have an ‘06 Shadow Spirit and I just finished the reassembly and test drove the bike. Based on your procedure for removing the Welch plugs and adjusting the carb settings, I am very, very satisfied with the results. I bought the bike with V&H Straightshots but had a problem with backfire during deceleration. I didn’t know if the bike had been jetted and the only way to tell was to inspect the jets. I needn’t tell you what that entails but I really didn’t want to go there. After finding this video, I decided to duplicate what you demonstrated and it worked perfectly. Backfire is gone and the bike runs great. It even increased the idle just like the video and I was able to dial it back down. Thanks for a job WELL DONE!!!
Don’t you just love it when a solid plan works out?! So glad you got the result you wanted man. Enjoy it brother!
So far you have helped out a lot. I have the 1979 Limited Edition CB750K that you did the carb sync on. I had removed the baffles to discover incredible power waiting. After restoring her in Spring 2021, I had a Vintage Motorcycle co, tune so to get it past inspection.
Things were okay for about a week although some deceleration backfire.. Yesterday after highspeed driving on the highway for about 5 min's, the lean symptoms showed up. I had enriched the mixtures since before. Still some deceleration backfire - so further enriched. and deceleration backfire became minimized.
But after exiting the highway yesterday, when winding down to a stop, engine shut off, and idle simply would not sustain, and would need to rev her. It seemed like a manifold leak, and also the Carb No 1 was having loud backfires during idle suddenly.
After limping home, with engine case @ 240 F Temp, and after cooing down, drained float boil one and injected carb cleaner directly into the Boil via its drain hole. This improved things somewhat. The Manifold Boots had been replaced, and new hose clamps tight for a screw driver but not firm for a ratchet.
Just got back after some further testing, Im using STP Ultra to clean the fuel/ carb systems.
Just a little back fire to watch on Cylinder 1 -
Thanks again for your help and for reading this -
I've got a 2000 Honda Shadow Sabre 1100cc, and thanks to this video, I was able to enrich its lean mixture and increase the idle speed. It's running much smoother. Much appreciated MD! My next step will be to install a K&N high-flow air filter.
I just popped out my baffles out of a set stock harley slip ons on my honda vtx1300, and I'm back firing, too, on deceleration. I'm glad I found this video. Thanks.
This guy is a god!! I'm running aftermarket Vance Hines Longshot exhaust and ever since my bike has been running lean and I never knew it till I watched this video. 97 shadow 1100. Couldn't thank this man enough. I been running like that for 2yrs now.
Hey Nicholas, I have a '96 Shadow 1100 Shadow as well. So was it just those two screws which solved your issue? I'm getting slight backfiring
That last minute of advice you gave is exactly what I needed to hear, your an excellent teacher brother.
Your a gift that keeps on giving. thanks. Time to fix my Virago. Had a 1977 GoFor with 900 org miles and sold it to a perfect owner. I got a 1994 XV750 w/5000 miles. I definitely will does this.
I bought a 03 shadow with cobra pipes and after market air filter. Kid said it had been jetted. Back firing like crazy. He said its always done that. Thanks to your video this old timer is good to go. Keep them coming. Thanks so much.
Actually seeing the carbies getting a tune up and hearing the result, is brilliant thank you
The jet kit changed the main from 112 to 118 and slow jet from 35 to 38. Who knows if larger or smaller due to scale differences. Stock needle with a washer to lift. no drilling done. I rode and put the choke 2/3 closed and it improved, minimal popping. Ill add another washer to the needles and turn them out and test with service tach to get higher idle. I have an inline fuel filter with a clear outer cylinder so I can see it is getting fuel. I checked a plug and insulator was white, electrode dark. I do have the K&N air filter in stock air box, so I am getting more air so, definetly need more fuel. I rebuild the petcock recently so it seems to be ok.
Love the thumbnail! That is my bike. That oil line under #2 make adjusting it a PITA. I really appreciate your time and expertise.
Ken
Thank you for all that info! Indeed both the K&N and new pipes increase your flow through the motor quite a bit. Adding another shim may be a good choice, I just hope your able to get the retainer back on to hold the needle in place. Definitely give the mixtures a turn out as well, if it it's not enough going up two too 3 sizes in the mains may be the next feat. Glad you like the photo, that my 750 that I'm trying to get dialed in! You are absolutely correct that oil line is a headache especially when you have been fighting with it for long enough for the motor to get hot! Best of luck! Keep me posted we need to solve this!
Bro, I just did this on my bike and si far so good. It already idles muuuch better!
Good video! I own 25 bikes and have done this with every one with good results. I truly believe it is the ethenol in the fuel now that is causing the lean idle mixture condition.
Scott Miller Nail on the head Scott! So easy and so practical!
I just want to thank you for your video it's the reason my Yamaha r1 is now fixed. the previous owner for some reason had all the fuel mixture screws closed all the way in I didn't noticed and thought the carb was clogged I took the carb off multiple times to clean and couldn't figure out why it was running so lean the bike popped on deceleration and ran like poop after your video it now runs like a beast and no popping
Yamir929 This is music to my ears! Great job for figuring it out brother. Glad this video was able to point you in the right direction! Be careful out there!
XworksTV Dude my 2000 R1 is running like poo. I'm now convinced this is my dilemma, based on your comment. I hope this solves the issue.
Bullock Wagon good luck it's an easy fix if it is just a turn of the screws in each carburetor
XworksTV I can't seem to locate the proper screws. Any chance you can send me a PM with a picture of the proper screws. The frame is all in my way haha.
Bullock Wagon there is one per carburetor it's on the bottom of each carburetor by the float bowl it's a copper Flathead screw
dude, holy shit... Where have your videos been my whole life? How did I just now find your channel? You need to be known, Subscribed!
+idkman 🤙🤙
Hi there Doc, well I been wrenching for over 50 years taught 9 and you did a great job explaining the mixture adjustments and getting it done.
I always have used dorky sounds to explain the engine working or asak for them in diagnosing a customer complaint. Keep up the good work!!!
It’s a great pleasure watching a great motorcycle mechanic
I paid a solid 3 digits for my bike, because it would not run. $7 worth of plugs and i was riding, got to drop my first ever bikewave lol. looking forward to your videos as i turn my POS into a very nice first bike. thank you
Been having issues getting my 75 cb 750 running clean. This and other video on syncing carbs has been more helpful than any other videos. And I've watched them all.
Whats up Cody, just wanted to thank you. These videos have enabled me to bring my father's bike back to life, and I'm looking forward to getting it fine tuned. Keep up the good work bro.
You dont sound like a dork you sound like a genius, i have just fired up a bike carbed car for first time and gona have a go 2moro gettin it running right, the tip on throttle linkage was a big help in gettimg my car pedal returning right and your vocal guide of what the revs are doing are so helpful, i struggle with understanding written info in many ways but you make total sense, thanks braaah!
Previous owner had destroyed the screws heads and any movement i could achieved didnt do much so switched to a cbr600 set to have them fill the floats then conitune to piss fuel over the starter out the bottom haha i think theres some double back hoses missing, more rnd might be time to invest in a refurbished set, have you ever tuned a set on a car engine? That would be a sick video seems less common knowledge more only set people know how, the principle seems the same, but be cool to learn the difference in application
@@flybikesbmx6242 cars are a little different but I can help. Feel free to contact me. I'm an old car wiz man. When I grew up we fixed our own and I'm more than happy to pass on what I know.
An additional tip I would give is at 4:02 to make sure to turn your fuel line to OFF before you remove the fuel line, otherwise you will have gas spilling out of your tank.
What up Cody,
Watched all your videos regarding carburation and jetting.
I've been bought up on 2 strokes 😁.
I'd like to say thankyou dude for guiding me to set up my Honda cbr1000f , she's now running like a Rolex watch now😉💪.
Best regards dude ,
Rich in the UK 🏴🍺👍
I agree, this is the best video about adjusting your carb. Thanks bro
+Anatolie Murug Thank you!!
If you dont know how to do carbs this vid is great
Thanks man!
Dude you have so much patience. It's a shame that they make these adjustment screws so difficult accessible. They should be very accessible.
Nice Video thank you for your time making it.
I've watched a lot of videos in the last few days and by far this is the best I've seen yet, great work my friend
wow my bike is running better then ever. now ur the man thank you not a single pop I got it dialed right in boom thanks again
bart groves So pumped to hear this brother!! Good job man. Enjoy 🤙🤙
Thanks. I decided to show my wife I can fix a 02 Honda shadow spirit VT750 that her X left behind. It sat for nearly two years because it had a problem three "Bike" guys couldn't solve. Im an I.T. tech and I got it working. It wouldn't start before. I got it started but had to do a lot of small things like replace the battery, fuel pump relay and rebuild the carb. It runs and I can ride it but I am having many of the carb problems you described. I have adjusting it and am still getting some pops on the decal and funky hesitation on acceleration. Been having a hard time pinning down the perfect mixture. I wanted to hear the sound of a good working carb and im hoping that now that I hear the sound and your explanation of what certain sound like long BRAAAA! indicate, I am going try another adjustment today when I get home. Problem is its so damned hot here in San Antonio and the sun hits right into the garage so after five minutes im dying in my pool of sweat. lol. I have never had a motorcycle license or really drivin a bike. I drive a stick so learning to ride the bike up and down the street as I fix it has been easy. Im going to buy the bike for $300 from my wifes X and learn and eventually ride it so this video is a big help on just how it should sound with mostly OEM parts and no mods. Cheers.
No mention was made of the fact that a vac. Leak will cause b f on decel. Very good tutorial.
This is what I have been looking for the last few days. Just got my carbs put back in after a clean and looking for an example on how to do this. Awesome
For newbies when drillig the carb mae sure your drill chuck isnt burning or cuttig your wires hanging in your way. Its easy to focus onwhat youre drilling and not see wiring harnesses getting damaged.
Amazing video, just what I needed for my Vstar. Thanks! EDIT - I just did what you instructed and my Vstar now runs like a dream. All back firing gone. Thanks!
When I pulled the plugs on my bike, I used a sheet metal screw. I ran it in the first hole, and grabbed the screw with a pair of pliers to work the plug out
You're a great teacher. You explain the hows and the whys equally well. This helped me so much. Thanks!
Hi Cody, great video and the explanations you gave near the end were very clear and will be very helpful in trying to tune the GSF400 I'm resurrecting!! If possible, it'd be great to see a video of this procedure on an inline 4 to hear the sounds diference between a 4 and a v-twin.
A tip, I do film lighting for a living, wear long sleeves when you arms are so close to your light source. The reflection from you bare arms is bouncing back and messing with you camera's focus so the area you're working on isn't as clear as it could be. :):)
+Chris Chalk This is actually a fantastic tip! I did not know this!! Thank you for your feed back!
After the first drill bit you can always use a short wood screw and screw it in a few turns then use pliers or vice grips a pull that plug out. Saves time.
This is cool I wish I knew about this prior to selling my vstar for practically nothing I couldn’t fix my self and didn’t want to pay more out of pocket to try and get fixed this tech is very honest other would’ve charge me for carb cleaning and all that and they want 300-500$ for that alone.
Thank you
$300 for carb cleaning? Bloody hell thats only like a 1/2 hour job and $2 of carb cleaner used.
I see what you mean though, two of my freinds ran their 2 stroke scooters out of oil and soft seized them, the local shop wanted to charge $1500 aud to replace the whole engine. I fixed both of them in an hour doing nothing but injecting oil into the cylinders to get the rings seated and sealing again and both ran perfectly afterwards.
Fantastic video. Im doing this to cure my popping on decceleration. Thank you.
Thank you for this. I am about to pull my carbs off to check for clogged jets. If that doesn't solve the issue, I will try this.
great work as always Cody. I would like to give you one of my tips for plug removal. instead of drilling out to such a large size I drill a small hole in the plug and than insert a screw and pull the plug out. it has worked great for me for years.
acerider2005 Absolutely. That’s been my dads go to since the 80’s. Use a small bit then a pick to pull it out to keep everything clean and undamaged. Sometimes they can be in there pretty good though.
OMG! You are the man!!! Thank you so much! Factory had my air/fuel mixture screw only a half turn out then covered it up with the Welch plug. Absolutely no reason to apologize for sounding like a dork with the engine idle/rev sound effects. When I rev it takes a while to come back down. Now I know that's too lean, will open up the mix screw some more so it drops down faster. Thanks for showing me how to tune my bike. Performance 100% improved and will only get better with further adjustment. Feel bad for the guy who owned the bike for 13 yrs and didn't know about that welch plug. I'll bet that bike has always run like garbage until now.
Thank you man ! I’ve had a backfire for over a year now hopefully this helps me out tomorrow !
great video im sold after reading just a couple coments . cant waite to try this i have 03 shadow spirit 750 having same problem pipes were cut baffles gone same air box popping on deceleration exspained in detail n right to the point and im glad i did buy the rejet b.s. kit thanks
Just picked up a 99 with the same issue today for 1500 bucks thanks for the assistance
I’m pretty much addicted to this content.
Cody….damn I wish we lived in the same area. I am beyond thankful for the info packed videos. I pulled my carbs last night and installed a jet kit and used these videos to make it a hassle free install.

Go Ride :)
Hey Todd! You installed jets? Were they Cobra jets by any chance? That's what I'm running and posted a question to Cody to see if he can listen to it and see if it's running ok.
@@mr.recruiterp3583 Dynojet jet kit, Cobra Slip Ons, K&N air filter.
on my VT500C copper chopper, i have low backpressure harley slashcuts, on extended pipes, and have a over run backfire but mine im sure is from a tiny tiny amount of oil that seeps past the exhaust valve guide...yes i forgot to change the valve seals when i rebuilt the engine..BUT I LOVE IT, as the bike is done in a vintage look, see the videos copper chopper, it pop like an old car or many vintage engines..she uses a tiny amount of oil but that just means she gets an egg cup of oil every 400 miles
that's ok for a 1985 engine... and my screws have been ajusted just under 3 turns, and i have bellmouths with easy breathing filter inside the belmouth. and she has the same 800rpm tickover when cold or hot. she needs choke when cold and that gets pushed in as she warms up, and if i stall the engine hot, she likes a tad of choke to start, so is still very lean.. I will try a further 1/2 turn out and let you know if this changes anything.. but burbling along in 6the in town at 800 rpm, and a lovely backfire if i go downhill and close off the throttle, she gets attention with loud pops from those pipes...awesom .
I just Wanted to say thank you so much for this video. I have a 2000 Yamaha R1 and have been struggling with the exact symptoms you talked about with backfires while idling and Narly decel pops since the ex-up delete and Graves ais delete. I'm gonna adjust my pilots tomorrow and make sure there all still in sync and then RIDE!!!!! So thank you again for all the pro tips and help on clear step by step instructions on your videos.. 🤙✌️
How did your 2000 R1 like the settings? I have a 2002 fzs1000 with exup deleted and it's doing the same thing.
My fzs1000 has the same motor as 98-01 R1.
Great video..have the same sounding popping in carb and backfire on newly aquired 1985 sr500.Found the fuel mixture screw (near engine ) so will start at 2 turns out and go from there..
i learnt from forums that we cant make much additional horsepower simply by allowing more air to flow in the carbs... we need to provide a larger pilot jetting to allow more fuel to flow with that added air intake and have a better unrestricted exhaust pipe to allow quicker dissipation of the burnt gases..
intake
jetting
exhaust
With a long drill bit i was able to do this with my tank and throttle still on. thank you for your video it gave me the curage to do it myself and my 05 shadow sabre 1100 has never sounded so good.
You are a Genius...thank you so very much . God Speed to you and all you love . Thank you
-Michael Cunha
Thanks for this great video and all the explanations. I have a 2006 Honda Shadow Spirit - have some acceleration backfire, and at idle as well just like in this video.
Now I at least know where to start next weekend!
+Andre Kadibelban Hope it cures the issue!
While you may think you sounded like a dork, you accurately described exactly what my bike was doing after I fiddled with the pilot screw. (The taking longer to return to idle problem) So now I know it is running lean and I need to open it more. (I have the "D" head screw on my carb so it's not so easy to adjust.) Thanks for your time and making this and all the other videos. Kudos.
aquaman0167 So glad I was able to "speak the language" in a way that makes sense! I think you hit the nail on the head with turning the mix out for the fix! 👌🤙
btw - for the shavings - try placing a magnet near by
With all the videos I've watched for research, this one is the most understandable. I will work as you advise, man! Thanks!!
You sir have received my first subscription
WHAHOO! Thanks!
Thank you My 2003 Honda VT 750 runs much better I also checked for Vacuum leaks before doing the procedure and I knew the carbs were clean I had them apart a few years ago also I replaced the Air Filter and the Fuel filter before doing the adjustments. Again Thank You :-)
Good point-of-view photography. Use a diffuser on the light to avoid hot spots.
Excellent explanation...! You have open my eyes. :) best wishes for you! Straight from Warsaw in Poland!
This was really a great video. It's the actual management of the circuits working together you covered and that is on the fly super advise. Thankyou so much!
Great demo of tuning the carbs and explaining the desired result
Plus... the tune on that 750 sounds immaculate
After a few videos watched, this one earned my sub!! Well done.
I agree
I didn't really think of that because the bike was running before but I'll give it a shot
Exhaust poping/banging is not backfiring. It is actually called after firing. Back firing occurs in the inlet manifold.
After firing , is also called after burn. Thanks for the info 👌
@@TheMotorcycleMD You showed me how to fix my vlx600 that a ?'mechanic' ? destroyed a year ago. Refused to go back to him. He gave me bike back after 8 months, with a zip tie on my chock. He even showed me how to slide it up and down. Unreal. Thanks Cody, I have a bike again. I also replaced my brake fluid and bled, with needle nose pliers, like you showed in your video. Better than ever, great tip. I'll be replacing coolant next, thanks to you. Hope all is well with you.
Thank you compadre! ✊
Who knows how much money you save me.
I had the exact same problem. it's fixed now. 😎👍👍😎
Best video I have ever seen on this procedure. Well done.
Thanks for taking your time to make the video!
This is the best video I've found on TH-cam for proper adjustment of the fuel mixture after changing jets, pipes or airbox. Plus, you are an excellent teacher.
Thanks a million. Tuned my carb in under 10 minutes. Great video man!
Thank you for the video and education. I'm working on vt1100c carbs now and this has been very helpful.
Oldguydoingthings
I'm about to work on the same carb on my 97 Honda Shadow Spirit. I took the bike out of storage, and the crankcase filled with gas. I think I have a stuck float. I'll clean it all up, and apply the adjustments in this vid and hopefully be all set.
I learned a couple of lessons that might be helpful. The major reasons my carbs gunked up was due to the petcock leaking continuously into the carbs while turned to off position. Had to buy a new one. Also, i had been using gas with some ethanol in it. i now totally avoid ethanol contaminated fuel in bike and cars generators, etc.
Hi there,you can certainly work magic on carburetor's ,that was serious tuning,I've never seen anything as advanced as that ,WoW well done & Excellent Knowledge friend😊😊😊
I can't even tell for how long I've been searching for this idle mixture tutorial. My XRV had issues, and no one seem to know how to set it properly, previous owner had gunk in tank and broken vacum line so he though " Im gonna solve this with totally messing idle mix and carb sinch." well didnt work so he sold the bike, i noticed broken vacum tube right away when buying. so i fixed that, thend cleaned tank, and after that bike started runnig better, but weirdly at idle, so i tried to set these so they are the same at both carbs. Now I know how to identify the sweet spot so I'll get to tuning. :) thanks!
Great video. I was having problems with my shadow. All fix now thank you man you saved my bike!!!!
Best video you published.
This is the exact video I’ve been looking for. Awesome and clear
Hi Cody. have you ever made any videos on switching from airboxes to pod filters and the pros and cons and modifications needed to do so? Be really cool to hear your views if you ever get a chance. Great videos!
+olrenison Great question! I'm actually working on one now! Be sure to subscribe and turn your alert on so you get a notification when the video comes out!👍
That's great! I'll look forward to your words on it. I'm not so sure it's a great idea for us UK riders where we see a lot of rain but it looks so good.
You're a frigging genius mate. Wish I had a quater of your knowledge. Thanks for sharing it.
Awesome video, thanks!
That really cleared it up for me, my bikes are running too lean. Tomorrow is going to be a good day. Subscribed.
Drill the plug once, then screw a sheet metal screw in until it bites, pull out with a pliers.
+steve moriarity That technique works very well!!
Exactly, Drill 1 hole, use sheet metal screw to remove - That's the way the Honda service manual says to do it!
@@kaboblewis1333 Suzuki says to do it the same way (old GSXR 600). They also say to use a "3.2mm-inch" drill bit.
i got a little rig like a little dent puller works good
This is what I was thinking. Use a screw. But it works either way.
After you put a hole in plug you can thread screw in and then grab with some pliers and pull em out too
thank you so much it had a bad vacuum leak on the right carb boot
Thank you so much, I watched two of your videos today and it helped me understand what's going on and hopefully I will be able to fix my decel popping.
Cheers!
BRO! replacing the thermostat this week to get my bike back up an running, and was contemplating messing with the A/F mixture, gonna do it for sure. still a little nervous about drilling into the carbs but i should be able able to pull it off. looking forward to my "new to me" bike running well again.
Dude thats a great video . explained so well . I struggle with the cable adjustment i like how you explained it will put it to practice
+yulaw5110 Awesome man, glad I could help!🤙🤙
Very informative video, doing this to my 05' VT750 this weekend! Thank you for this
That's really funky compared to my CB750
Hola Jhon No se tu idioma ingles, entiendo un poco el texto en ingles, pero como dice el dicho: mas vale una imagen que mil palabras. Asi que trato de entenderte lo que explicas en tu video en cuanto al carburador de la motocicleta, por la cincronia de las explosiones emitidas. Eh visto varios de tus videos muy buenos por cierto. Te has ganado un suscritor mas y manita arriba. Gracias por tus conocimientos. Saludos desde el sur del pais Mexicano.
Hey Cody, just saw your video on "Deceleration Backfire: Tuning your carburetor" and found it extremely helpful. I just finished the clean up of the dual carbs on my 2000 V Star 1100 but have been having a hell of a time getting them adjusted. Since it appears that you work primarily on Honda, I'm hoping that a lot of the information about tuning transfers over to the Yamaha carbs. Chances are they both use Mikuni carburetors so the responses mimic one another. Right now as a starting point the OEM adjusting screws are set at three turns out but the engine response sounds very similar to the lean setting you illustrated in your video. Uneven idle, backfire, misfire and idle stop. I've ordered new thumbs screw style adjusting screws because it is next to impossible to adjust on the fly with the mixture screws inset and under the carbs with little to no space allowed to get any tooling in to adjust. Thanks for the video and I'm feeling positive that this will be an answer to my carburetor problems.
Great video!! I have a Vstar 1100 that I bought and have the deacceleration backfire as well. It has custom aftermarket pipes that I believe caused the problem or the bike might have been stored too long with old gas. I was going to get into taking the carbs off and cleaning, but after seeing this video, I will go with the adjustment route first. Again, GREAT VIDEO!!
