I love the fact that you do all this work on Honda Shadows and not Harleys. I like Harleys, but own a Honda Shadow and love it. Your videos are great and keep them coming!
This series is exactly what I needed 🙌🏽
TJ, I'm still in process of building my VLX and I for one appreciate all that you do for the Honda community! I got my jets from you months ago and I'm just now tearing into the carb. Gotta replace a broken choke line and both of the diaphrams I found out. Previous owner did a Mickey Mouse fix-it. Anyway, thanks for these videos. It's always good to be able to reference an experienced experience. ;)
Exact tutorial I needed. Thank you for putting this out there.
Actually, the reason for the two different main jet sizes is because the rear cylinder runs hotter due to less air flow around the head. Running the rear richer keeps it cooler...
Easy to confirm with handheld thermometer. Thanks.
Ahhh here we go! That might also be the reason why the smaller sister, the VT-125 has two different main jets! My 2000 has this set up. Starting 2002 they changed something and the kets then were slightly bigger and the sam efor front and back.
Best Carb video. Thanks, been struggling for a while and this will be very helpful.
Nice work on the videos guys! Has helped me immensely!
So helpful! Thanks TJBC
I'm not touching this!!! I'm a carpenter and there is no wood in there
Just the video I was looking for, thank you
great vid!! cant wait to get my order man!
Awesome videos! Thank you! I bought your rebuild kit for my 97 vlx600. Do you have a video or pics of how/where to slit the diaphragms?
Hey man thanks a ton for making this video. I just finished my carb rebuild and so I was watching to make sure I did everything right lol I saw your tear down videos. Great stuff!
Now when I turn the choke off on my bike it kills the engine tho...I'm curious, what would your process of elimination be to figure out the cause?
Wish he would do a installation vid on the velocity stacks
How nice having a VLX guru to make life easier!
🙏
Hey TJ! I understand the need to rejet after installing a new exhaust. A have 2000 750 ACE and I love the stock air filter it has on it, and I just want to add the backdraft exhaust with the performance tuning kit. Will running the stock air filter be a problem with this, or will I just need to adjust as needed?
Great Video:) I have 01 Shadow Ace 750 - After changing jets and Adjusting A/F screws, do you have to synchronize carbs?
TJ Thank you. Excellent video
You're awesome man! I'm a fan!
Thanks for the videos! I just got an 83 vt500c...and have been struggling to find carb kits. Is this the same carb across the board for 500, 600, 750, etc.? Excuse my ignorance, I'm fairly new to these bikes
god DAMN this helped a lot. Picked up a 94 vlx and I have no idea what the guy did to it, but it has zero power at full throttle. Sputters a lot, almost like it's starving for gas or air. I figure it's either a ratio issue, the jets or just shit built up in the carbs. Gona be looking for a universal kit and just clean/rejet the carbs, then dial in the ratio screws. This video helped immensely.
Hi Tj,
My bike is a 95 Honda shadow 600. I put your velocity stacks on and I chopped the heavy stock exhaust tips off and welded some turn down tips on it. I wrapped the pipes and installed the big jets that I got from you that were recommended in the instructions. The bike runs great except for when I get down on it real head or at exactly 65mph. Should I mess with the air screw or does it need diff jets? Please help!
Great video! I will do this myself using your video. Thanks
Hey, your vids are really great and entertaining! I was wondering if you would know, what model of Keihin those carbs are?
thx for all the great info I'm def getting a kit from you guys
Just to add, when you put the carb back on the bike (VT750DC in my case) the airbox usually gets in the way of reaching the air/fuel mix screws and the choke gets in the way on the other side. Im using a watch makers screw driver to adjust it of course. I may get the custom stems but its a bit pricey for my blood at the moment. However the custom adjustment screws would make it way easier. Keep in mind without the airbox/filter in place you are sucking in air as is and if its dusty you may suck it into your carb. So I would try to do this in a clean area and if you dare ride it up and down the street to test you adjustments be sure to just put the air box/filter back on. Its an extra minute or two hassle but if you spent all the time rebuilding a carb, might as well treat it right.
I remember you from the VLX usergroup. Good work. I'm on a 750 ACE now. Glad to see you doin well. Thanks for the tech advice.
Shite. Sorry friend.Wish I had known. I just bought a jet kit from Sigma on ebay. That's how I ended up finding your video. Picked up some used slash cut pipes for $100, Doing the 4 - degree timing mod, gutting the snorkle from the stock intake, adding K&N air filter, 39T sprocket. Should do it all next Saturday.. What else would you recommend? I bought the 750 ACE because it is 50 lbs lighter than the 1100 and is chain drive. I like getting a lot from a mid-size bike, instead of just buying displacement and extra weight.
Thank you brother for a great video. I have a 1996 VT 1100 Ace that I recently bought a set of Cobra exhaust for. I haven't put them on the bike yet I was waiting for after the winter. How do I know what size jets do I put in. I was planning to also put a high-flow air intake from K&N.
Great video, thanks for the info! I just ordered a jet kit from y'all.
thank you sooo much! this video was quite informative!!!
hey great video but i got a quick question... I have a 1995 honda shadow 600 vlx and i recently bought it and noticed that when i was going through 3-4th gear my bike started to bog not bad at first and only sometimes, then i ran out of gas cause bike has no gauge and i wasnt paying attention filled tank started but now it bogs out so hard that almost dies loose all sorts of power. i havent cleaned the carb out yet that was what im going to do this weekend but could that be the problem for whats going on. thanks
I understand how to put them on. I’ve had the carb apart a time or two. I guess I should have clarified my question. If I leave the air box and all of the original equipment on the bike in that area, will it be hard to get to the choke knobs that you sell? I seen on one of your descriptions that the shorty chokes work better if you take the extras off and use the velocity stacks.
Great Video, Very Informative! But you went very fast on showing where the Airfuel Mixture screw is? I still have the welch plug? and don't know which is the right plug to take out? there are 2 on each side I believe?
Wow. This might have just saved my bike. Great video
What do you charge to stock rebuild a single versus dual carb setup? How does one arrange the service? Love your videos! Thank you!
Alot of people say to use 2 shims per needle should i copy them 2002 vt750 ace cobra slash baffles out stock airbox k&n filter? Or only use 1 like you stated in this video?
Awesome video picking up a shadow this week.That needs carbs done.Do you have link for jet kit?
Hi TJ any tips of right jetting for dual carb honda steed 400, just want to get rid of the airbox. Its pain in the ass when it loosen out cause of the vibration, the bike malfunction.
Appreciate your help. Thank you in advance 🙇🏻♂️
GREAT Video, Thanks for the information
I have a question about proper re-jetting those dual carbs. I've got Vance&Hines on my Shadow and big aftermarket air filter (modified car air filter actually stuck to the pipe in the front) so it has more than enough air. The bike has been bogging down on full throttle so I suspect the main jets need to be replaced as well...which one do you think would be better 120 or 122 ones? Cheeeeeers for the reply bro!
Question: what size jets do you typically use for a 91 vlx600? I want to get the kit you have on your website but don’t know which size to use?? I know it comes with two different sizes.
nice video!
mine is a vt750ca. and just installed the cobra lo boy shotgun pipes.
i believe i am running to lean now :) ...
thxs for the video very well done.
can you remake this video please? i couldnt see much in this one and on my 2006 shadow spirit vt750dc i couldnt find some of the ports to plug that you showed. like they werent there. thanks for the jet kit and other stuff im yet to try them on.
hi I have a honda 750 ace and I will change to an open air filter and to cobra exhaust pipe. which jets do you recommend in your kit?
Hi TJ..
Do you have an idea of what i will gain from a rejet in hp ? i got a 96 vt 600 and the only mods so far is a K&N air filter :)
Best regards
Rasmus From Denmark
In this video you say to shim the needle with 1 washer, but when I was doing some reading on your blog it says to use 2 if it is a stock needle. Just wondering which is correct?
Your the reason I started working on bikes broke at 17 this video turned my 200 dollar shadow 750 in to the bike I still ride today
Do you have to adjust air fuel Mix with both sides of the carb? Or does 1 screw adjust both carbs?
cleaned and re-jetted carbs idles good won't rev without dying..but I'm replacing airbox yo see if that helps
If I were to buy a stage 3 jet kit for a bike that has a stock intake and a unbaffled aftermarket exhaust would I have any major issues with the bike running? or do I need to start with a small jet no matter what?
hey tj man I just bought a 2000 shadow 750 that's been sitting up for a few years and when I looked into the tank I seen white dryed up gas. I haven't tried to crank it the bike has 15 k miles on it and was a good deal I plan to clean the carbs today and the Jets too. I'm thinking I need a new tank too. what eles should I be on the look out for
Hey TJ, how much does a Carb Rebuild go for a VT750 DC and what does it entail/include?
Is it necessary to shim the needle when replacing the jets? or can you just replace the jets without the shim?
Hows it going....I just ordered your backdraft pipes and wanted to know what jet kit would I need for a 1996 Honda Shadow ace Vt1100
TJ I’m having a problem with my 97 VT1100C2 ACE that you might be able to help with. I replaced the coils with Accel Super Coils and went from stage 1 jets to stage 3 jets. I got everything button back up and started it up but she has a very bad backfiring at idle and when I give it throttle. I have checked for vacuum leaks and played with the mixture screw with no change. It’s louder when you give more throttle. Can you give me any advice?
If got a question... steed 400 dual carb... I’m running straight pipes but extremely rich I baught the bike like that from the guy... any ideas ? Maybe aftermarket air filter? Or should I rejet 🙈
So I was wanting to know if I put a stage 3 kit on it would that fix my problems?
May not relate but I would like to know if the shorty choke knobs on your website will fit a dual carb system on an 1984 vt700c
What’s your thoughts swapping a single carb to dual carbs on a 03 vlx600
I didn't clip the centre of the yellow plastic that hold s the spring. Can this alone cause my bike to bod on full throttle after re-jetting?
After reassembly of the carb I have gas coming out of a vent tube I believe? Gas was also coming out
of the rear side exhaust. @7:10 your finger with the D is pointing to the port the fuel was coming out of... Thinkn I need to check the float? Any help would be appreciated !!
Hi, I recently bought a 2002 750 shadow spirit bobber that was running like crap. It was running two pod filters so I bought the stock intake/air box system. Now it runs great but looks like crap. If I install this jet kit, can I then go back to running the two straight filter pods again?
Hi, Ive got a 1998 Vt 600 dual carb shadow. Ive put on your stax, and there was already a jet kit installed. Ive adjusted the air fuel mixture screws all different ways. Im having Running issues, It starts and idles fine when stopped. But when i go down the road it hesitates, pops. Any thoughts? Also( It may need a different jet kit) Im not sure.
really appreciate your expertise.
Hi , I have a 1999 vlx600 . My fuel pump keeps sticking and won't let fuel pump out . I have to put air pressure in the inline hose going into the pump till I hear a pop sound . It sounds like a rubber piece getting un stuck one it pops the pump works good . If I leave the bike unstarted for a week it sticks again and I gave to blow it free again . If I stat it every day it works fine . Okay here is my question can I just get rid of the pump and go right from the tank to the carburetor . This is the first bike I have ever had that has a fuel pump so I'm having a hard time figuring out why its there in the first place .Thanks for your help in advance .
What is that third jet looking stem? It has a tiny hole on top but has no way to remove it? Was just wondering. Its shaped like a jet but doesn't seem to do anything? Thanks.
I have a v twin the front cylinder the main jet is rich 90 and the back is 100..... Do u keep the front rich and the back more lean or match the jets or what?
Hey mam ordered the performance kit, velocity stacks, and backlash exhaust for my 750.. I'm here in California east bay area.. which jets should I put in?
Thanks. I would like to know how choke works in these carbs, if sometime you may like to talk about.
Google says vlx600(stock) can reach 160km/h tops. So can it reach 180 or 200km/h when rejetted? Or would it need more other tune ups such as port polishing, agressive cams, etc? Really looking forward to build one for cruising and for some "fun". You know what I mean.
Cheers from Phils.
Tj, how do I know what I can plug off on the carbs?
Can you tell me what can i do with my fuel tank, i got some stacks and they fit great but the back one hits the fuel tank. Now the back side of the tank won't go all the way down.
Do you know the model of the keihin carbs used on a vt750 ace 1998? And also the stock needle size? I need to get a needle that's a size or 2 smaller in diameter. Thanks.
hi TJ my name is Kenny from Ky on my carb honda 1994 600 VT is there a setting on the Emotion Tube and how to change Diaphragm that come in your kit . thank u
Do you have any videos on how to remove and replace the carbs?
Hello Im Going into your website to order the jet kit today, i need to have the drill bit so I can get to the air screws. I have a cobra exhust and Im ordering a cone shape air filter. what jet kit should I order???
Awesome video bro where can I get the jet kits. I recently took my baffles out. She seems to run fun but better safe than sorry
I put stacks on my bike and as soon as I throttle it sputters and shuts off
Or if I get it moving every gear is massively underpowered
Will rejecting with the dual carb performance jet kit coupled with a rune potentially fix this issue?
I have a 97 and removed the baffles...does it NEED to be jetted?
Typically, anytime you make a change to your intake or exhaust, you SHOULD re-jet accordingly, since your exhaust is now more free flowing, you probably should re-jet.
I apreciate these videos so damn much about rip thorugh my old 95 600 carbs and hoping a good cleaning will do the trick bike idles great seems have no main jet under load though
TJ, no adjustment for the float?? thanks
I have a 93 Honda shadow vlx 600 dual carb. I'm trying to take both carbs out to clean and possibly rebuild but I'm having trouble finding a guide on how to remove them without damaging the bike. I would like to do it myself as I don't want to spend the possibly $275 to have it done at a shop. Any recommendations or advice would be appreciated.
Any vids on a shadow vt1100 shadow for rejetting bud?
Thank you! It's the same carb that is in this video.
Damn, didn't go crazy tight, but may have tighten my jets a little too much after watching your video. Bottomed them out, then gave a controlled snugging.
hi love your vids man is this carb the same as shadow 125cc /
/?
I just have a maintenance question regarding idle issues as well as running issues. When I ease the throttle bike bugs, when I gun it the bike hesitates for a split second and then will get up and go. My fuel air mixture is turned 3 turns out please help
It's for a 1994 shadow vt1100c dual carborator. I do have larger jets in it as per guidance from one of the other videos due to the fact I have open pipes.
What size jets do you recommend for straight pipes on a vt1100t
Ok i have a problem with my shadow 750 ace when i turn throttle past 25% it cuts out and no longer accelerates what should i do to fix this?
Hey, I dont know if your still replying to these comments, but... I just purchased a 1992 Honda Shadow vlx600. I am planning on chopping out the stock air box and putting in air pods. Will this kit be everything I need to provide the proper air flow? Thanks!
In the dual kits you sell, what sizes are the pilot and main jets
I have a honda shadow 750 I rejetted it with a stage one dyno kit . It's not running correctly , could I have switched the main jets? Do the main jets differ from the left to right side of the carb? It was running then shut off and now won't turn back on. I put the fuel needle clip on the 2 slot and added two bigger Jett's and debaffled the stock exhaust . The bike was running perfect stock I justed wanted to debaffle it but now I wish I would have left it alone . Any ideas?
Do you have a video on how to balance or sync these carbs?
I recently got a 02 Honda shadow spirit vt750dc working after my chicks X left it sitting fro two years. It had 18k miles. I got a lot of stuff changed and cleaned out and got it running. I completely rebuilt the carb and replaced the jets. Its OEM. I have gone over a ton of videos and how to's on adjusting the idle and air/fuel mixture. What would help would be to hear an OEM Honda Shadow with duel carbs. A video with a bike properly tuned and hear how it sounds. Maybe a brief explanation of the stock settings which most of us know already but would have helped newbies like me. I am having trouble adjusting it and the factory setting seem to not be working. Still get a slight back fire and/or some hesitation on throttle. I know its idle should be around 900RPM give or take a hundred. I know how to adjust the screws etc. But I think if I had a good baseline sound to go off of I could get it closer to perfect. Maybe do a cold start with the choke open and then let us hear how it sounds if you rev it cold and then as it warms up and from maybe a standing position opposed to leaning to one side which I noticed makes a difference. Maybe its just me but I think hearing a quality recording of the sound at its best performance OEM will tell me if Im way off or not. Just a thought. Love the videos and parts. Cheers.
Tj i was riding around with my exhaust chopped off and my bike was riding messed up so i put a 50 jet in and my bike will not stay running what is the problem its a 2000 honda shadow 600 vlx thanks!?
I have a 1998 shadow ace 750 I had a shop put a stage 1 on the bike because the guy before me took out the baffles on stock pipes so it was popping .so now I bought one of those crome spike air intake & cover and now popping and running like crap so I took carbs off and put a 114 jets on it because that's what the spike filter came with and it still runs like crap and popps
i bought a 83 Honda Vt 750 shadow got it running but like crap i was cleaning the carbs i found on the air fuel screws one side had a small washer and o ring the other side did not have ether is this right or has some one been in there before me
Have you recorded a tutorial on how to sync these carbs?
Don't know if I've already asked you that.
Cheers
i got a 2007 honda shadow 750 carb was damaged in accident it leaks gas i believe its cracked runs good but leaks gas got another carb off a 07 shadow areo but it has extra ports where can u buy caps is it ok to cap will it work?
I have a 98 Honda shadow when I try to start if I disconnect the gas pump the Honda stay idle . When I connect the pump again the motorcycle over flow the carburetor and shot down. Any sudgestions?
