Why no jet cleaning the crap will come bk soon,like someone else said you do amazing work but when doing a job it need to be done right,(but you already know that)
Surprising that you didn't clean the jet's, that's where I have found most problems with dirt blocking them. I think you were lucky with the air filter not falling apart before now.
I want to sincerely thank you for your videos, I am not an expert mechanic but I have managed to dismantle and clean carburetors and change the air filter of my Adventurer 900. It has been a fun and stressful experience in equal parts.😅
I also did the cleaning recently. He was in a much more mournful state. Needle valves needed to be replaced, but even the gasoline tap had to be refurbished. It's synced and works great! Thanks for the movie, it was great!
Most welcome mate, I've taken carbs apart that are just a block of filth, every single component was horrible, but thankfully these were spotless and even before they came out, the bike rain like a watch, so a lot of time and grief saved!
Hey mate! If you took the carbs out it is just a small job to clean the jets and pilot passages. Or at least let it have a run in an ultrasonic cleaner! Noce to see where that darned throttle clip was originally. Never put that back on my bike :)
I have no objection what some reviewers says but it’s pretty clean in the bowls, no buildup in there as floats moves. At least you showed how it’s taken out, mentioning gas vapor ruin foam type filters ( I hate those!) absorbs oils too.
Many owners of these 'spine frame' Triumphs (like me) modify the airbox by cutting the back part just slightly to one side of the curved part. Then you can remove that half of the back and then take the rest of the airbox out the other side, without removing the carbies... It doesn't affect carburation as the cut is 'pre-filter'. Also, OEM Triumph air filter only comes as a complete airbox assembly. Or at least they do for Trophies.
No ultrasonic cleaning? After years of low miles ethanol fuel residue in the carbs could well have gummed up jets, fine air & fuel passages etc. As it’s such a faff to get the carbs off I would have done it for peace of mind even if the carbs did look in good nick.
Good to get the carbs out if only to change the filter. The jets could have been removed and cleaned having gone to all that trouble. Still an interesting watch though.
What trouble, I keep wondering what people are on about, it took 10mins to drop the carbs out and the jets were spotless like the rest of the carbs, why is everyone so keen to do work you don't need to do.
Carbs were spotless mate, didn't you see! The main concern was to check the diaphragms hadn't perished and that the needles were not worn, but as you saw even in the base of the float bowls, there was barely a scrap of dust and before I took them out, the bike ran like a watch, so no need to dig any deeper, I've enough jobs on the list still to do!
@@Moonfleet41 First Hose is at 1:52 and 3:26 which i assume is an air vent hose , 2:32 another air vent hose on the top going from the carb over the air box? 3:20 fuel hose from the gas tank?
@@Moonfleet41 thanks! So i can cleaned the carbs , put them back tried to start the bike but nothing. Carb bowls are full of gas, we have a spark but it Doesn t ignite . The bike starts then dies on starter fluid. Am i right to assume a vacuum leak is next? Is there a way i can private message you?
I work on an 01 Legend regularly. It really doesn't often need much. Next time I take carbs off I'm going to take the cable off the twistgrip. Have always wondered how to change the throttle cable. Now I know. That air filter is a pain. Used to be very expensive. Changed filter a couple if years ago. Carbs themselves don't give much trouble. My buddy quit riding in November when it got cold and started it last week (March) when there was a warm day. Started and ran perfect. Bike has about 80,000 miles
Wow, that's impressive!... I had the feeling when I bought this bike at 20yrs old with a lot of corrosion neglect, whether it would be ok, but it ran like a watch, smooth as silk and as you can see by the cams in the next video, it's not even run in, internals are like new! Truly a well built bike.
It's been 40+ years since I've taken CV carbs apart. Enjoyed the video. I miss Jim and your fro videos. Glad you're still making them. Tell the misses hey
My filter box was replaced with three individual cone shape air filters for each carb. Vacuum lines were plugged up. I think this is the cause of it backfiring. I got new plugs on it I might can check the coils the air fuel screw is two-and-a-half out still and I think I should have more fuel to the air that's going in it now. What do you recommend. Please help
I love these gritty videos Del, they take away the overwhelming feel to any jobs on a bike and educate the self confidence to have a go yourself. Within reason ofcourse 😌
Del, Since you're leaving the stock air box in place and having made a custom exhaust, do you expect to have to rejet the carbs with the change in exhaust? Keihin carbs on Triumphs tend to be really finicky and any change in either intake or exhaust and they don't seem to run properly. I have a 2000 T'Bird std and while I don't mind the stock airbox, other than it looks really clunky, I would like to change out the peashooter exhaust for both look and sound. But, I really don't want to have to rejet and resynch the carbs. Thoughts?
I won't know at this point mate, I may do, I may not, I'll find out when I get it back together and run the engine, at the very worst there might be a faint possibility I have to fit a dyna jet kit, which is no great shakes aye!
I’ve just been through the carbs on my 1998 Thunderbird Sport, ended up replacing the stock air box with individual pod filters and rejetting the carbs.......it runs a lot better plus removing the carbs is a 5 minute job.
Hi Delboy, great video, I have a Triumph Thunderbird Sport with Keihins, the throttle slides do look a bit scored on mine, but all three do move easily enough when assembled,. However they do seem quite loose in the slides, and bike misses like hell, more so at low revs, and not too bad if throttle kept still. But as soon as its turned, big misfires and flat spots.. year 2000, 36k...any suggestions.. thanks
Del good vid. I was a carb fitter many years ago, did cars, boat, bikes, and specials. You will find on most occasions it,s the rubber parts that will give you trouble. ie leaks air and fuel. In high mileage vehicles excess throttle spindle play will cause poor running and impossible to set up. we used to re bush the body of the carb, nowadays it will probably have to be replaced. As for jets very rare for them to block as most vehicles have a fuel filter, more likely that a crankcase breather will cause carbon build up on a slow running valve or similar device that uses crankcase vacuum. You did worry me as you had the float chambers off and didn't replace the RUBBER seal/gasket,You will probably get away with it as low mileage bike. Chances are if gasket is slightly proud of float chamber you will get away without replacing. Also did you check the needle valves ? Not good Practice LOL! Please don't think I,m having a go at you. I love what you do and you helped me with disc bobbins, so trying to help you back. Cheers .
I'm sure you saw how spotlessly clean those carbs were mate, and I do feel that listening to the blather from some people, that they're not satisfied till you tear everything single component apart but the simple fact is, this bike is barely run in, like you said, low mileage and a fuel filter in the line, they were spotless, just a little oily build up on the back of the slides which washed straight off, as you saw too the diaphragms were perfect, like new, and the bowl gaskets were nice and proud plus quite soft still.. this is a well cared for bike and when I rode it in, it ran like a watch!... so like the old guys say, if the cart ain't broke, don't fix it! Thanks for your insight mate.
Nice video Del & Penny. That air cleaner has seen better days and I can see why, not the best bike to do a a fast filter change on lol. Penny and you have a great week. Cheers
Very good video as usual, there are two things I would have added. Like some other comments say, I would have taken off the floats and cleaned the valve seats also have checked the jets. It's easy enough and while you are in there??? You also sprinted past the need to synchronize them with a quality gauge. Secondly, I have found that with CV carbs it's important to check the diaphragm for any sings of old age. I usually pull them out and hold them up to a strong light source and look for pin holes or any cracking or brittle areas but other than those two pet peeves of mine I liked the video. I find myself hooked and once I start watching I can't stop! Thanks and keep up the good work.
Did you maybe skip through the video by any chance, did you not see me remove the diaphragms, check them close up one by one for cracks and perishing, check the needles for wear?? I'm curious as it seems bizarre that you would criticise something I did in detail and showed in the video, check again 7:03
@@Moonfleet41 I recall you cleaning the needles but I didn't hear you say anything about the diaphragms...sorry if I missed. I do have a question......I have a HD customer who also has a Trimuph. A 2013 America complaining of rough idle at start up, and long warm up times before it will be happy with no choke. He said the last shop just had to clean out the little hole???? And that helped. If I do decide to pull them clean an sink em do I need a special fitting on the vacuum access, or is it just hose to vacuum port? I think they are Kehins I aint had it in yet though. Any info on that model would be helpful though.
@@Moonfleet41 ok you did say the diaphragms were perfect, but you didn't say how you came to that conclusion. Think if that was your only MC and you never cracked open a CV carb...you see what I'm getting at.
@@Moonfleet41 Ok! Thank you😊 another question. Are the carburettors on your triumph thunderbird the same on my triumph adventurer 1998 maybe? I'm thinking about to clen my carburettors and dont know what renewal kit to buy. They look similar to yours. On my bike there is keihin cvk carburettors.
Your methodical step by step approach will surely have given those previously "afraid" of attempting such a task the confidence to give it a go Del - in my opinion exactly what TH-cam is all about - great job - thanks as always for sharing!
@@garethross6258 - I am an auto electrician working on HGVs - my biggest challenge is always "getting to the fix" - especially considering they way in which modern trucks are put together - what Del has done here is equip people that don't pull bikes apart on a daily basis to "get to the fix" - it's then down to them in how far they go - dependant on the issues they find - in my humble opinion - a valuable and informative video - and it would appear that as it stand currently - 836 people agree with me? Thank you however for giving your consideration to my comment - I look forward to watching your video showing how it should be done - please feel free to post a link to it when it's ready to view. God bless you and stay safe!
@@mikeopenshaw9128 not my vid no... but one of the better ones and very much more in depth and informative towards cleaning and rebuilding carbs... all Del did was clean the bowls and slides lol... Was a video necessary for that? And he said he was going to be cleaning out the jets? He did not go near them? You best read all the other comments and watch this video yourself th-cam.com/video/95nlrP-yn2I/w-d-xo.html
Hi Del- after a long, tough day it was quite nice to put my feet up and watch this vid. Hard to believe that Triumph designed such an odd aircleaner mechanism. Indeed, no wonder the original filter was still in there! Good to see Penny 2:29! Hope you both are doing ok. 🏍👍🏍
Hi Gary, always good to hear from you and we're glad to hear the video gave you a little lift after a stressful day... you both take care there and keep safe, D&Px
Not sure that is the origal air filter. From memory the air filter and box are sold by Triumph as a 1 piece unit (ie, to replace the filter you replace the box). Hence most people replace them with aftermarket filters.
@@Moonfleet41 , think ours was paper as standard, inside the box. Replaced with a K&N because I object to throwing the airbox away to change the filter!
Recently bought a 99 Legened as a do it up as I go along job. So unfortunately can't go full project bike. These videos are invaluable so thanks. I'm from Hinckley originally so always wanted a Triumph. My only criticism of the Legened is the Air system! I mean WTF! As I am going to have the cards of to sort the air filter will give them a dig out. Seriously thinking of putting pods on to 1) save the hassle and 2) free up a shed load of under seat space! Anyone an idea of the jetting for pods? (I know it depends on the pod, but a ballpark would be nice).
Loving the legend but I have to agree with the other comments about not cleaning the jets. I hope you also cleaned the duckbill filter in the fuel line which must have picked up some crud over the last 20 years. And if you're going to run a less restrictive exhaust than standard, you'll want to take the idle mixture screw 2.5 turns out or you will get excessive pops and bangs on the overrun. Once the carbs are back on the bike, they're nigh on impossible to adjust.
My old Ninja 250r would get what I called "carburetor slide slap" after 5-10K miles. The slides would rattle back and forth, making a rhythmic tapping noise at idle, but disappear when throttle is applied. I eventually isolated the culprit with a mechanic's stethoscope. As far as I could tell it was harmless, but it happened over three different carb sets (kept buying more when I was young, dumb, had OCD about every new noise, and threw money away). I'm assuming this is pretty common... ever hear about or experience this?
I don't know what carbs they used on that bike, but the Mikuni flat slides I put on my old GSXR years ago used to clatter like castanets on tick over and it was quite normal, and like you said, went away with a tiny bit of throttle, basically they were just bouncing off their seats on idle!
Hi Del, the carbs don't look to dissimilar to the ones on a GSXR 1100 from the 90's. i used to race F1 sidecars and used the 1127cc suzuki motor, a dynojet kit will transform the fueling if your budget allows. Another tip with this type of carb is to check all three float bowls all sit at the same height as the brass holding arms can weaken over time. If I was still in the UK i would buy this bike off you in a heartbeat.
Hey buddy, you are very perceptive, those carbs are exactly the same as the CV flat slides used on the 1127, just one less obviously! And I was surprised how clean they were inside, as for sale when the time comes, be happy to ship it, already had a couple of requests so it may be well worth considering?!
Not sure what your name is but, I’m glad I found your Channel. I think you’re awesome Bike mechanic. Your attention to detail is awesome! Now if you can just come to Oakland, Ca and help me with my 2000 TBird Sport that would be great 👍 Thanks..
Very nice video! I am considering using Triumph carbs on an old Yamaha triple. I noticed there are two tubes for fuel near the bottom of the carbs but what are the two tubes near the top of the carbs used for? Are these vacuum lines or just vent lines that exhaust to atmosphere?
Hi, maybe you know, maybe it's mentioned in the comments below, but; a lot of people make a side entry on the airfilter box to simply remove/clean/ replace the airfilter. Cheers from Holland. Sold the bonnie, but it was a blast working on it with your tips and tricks as back up :)
The tbird carb removal is a little easier than the other models of that era. A bit more clearance? I would've changed the o rings as a precaution? They harden,and crack over time,and readily available on eBay,and not really expensive 👍
Del... Another awesome video. I would say you are lucky. I have never had the screws come loose that easy especially the float bowl ones. They are usually all striped out and I have to come up with clever ways to get them out.. Great job!!
I think you're right mate, I did feel blessed at how well that went I have to say, I think it's a testament to the fact that they've probably never been apart, so the screws weren't pre-chewed!
@Shed Life Yes indeed mate, it is often a little smoke and mirrors in some places, and many techs will know the sinking feeling of having to get work done on a stopwatch when there isn't enough allowance to do it properly!
Did you see how clean those carbs were mate? Absolutely spotless, like brand new inside and the bike ran like a watch, like they say mate, if the cart ain't broke, don't fix it...!
@@Moonfleet41 True ......BUT.....the carbs should have been built for the NEXT 17 years of service. Carbs should have been properly cleaned and new rubber parts installed. That's like saying that you never have time to do it right but always have time to do it twice?
thx a lot for share , this is the vid that i was waiting for , i have a legend tt , with the carbs out of the bike , i will cleaned and wait for the sync video , i had a lot of problems with this carbs with and without the air box , currently i have just the airpods due i lost the air box , but anyways , thx a lot !!!
I cant believe how rotten that filter was and the engine was running ok, the motor will certainly like a new filter. Great video and nice to see some carbs. Kind regards mate.
Cheers buddy, you're right, I think that filter was made by Mr Kipling, but the new one has arrived today, so all good to go... hope you're enjoying the Harley mate!
Thanks Del, I’m really enjoying the Harley, I’m astounded how comfortable this one is, I’m only in running in mode and on small milk runs but i can feel its pretty quick. I love it.
Hey Del, terrible air filter box design... I thought my bandit was a PITA because I have to remove the gas (er, petrol) tank... Next time I do it I will think of Triumph. Thanks for the video.
Sure thing mate, think of the poor old Suzuki GSXR that inspired the Bandit, the early 1127 models you almost had to take the engine out to get the air box removed!
So I'm also intrigued that you didn't clean out the jets... however, since you've installed custom headers and since you're installing a new air filter, I'm going to hazard a wild guess and predict that we'll be seeing a cheeky little K&N number going in that airbox (or possibly even a sweet set of pods and an airbox delete) with a naughty little rejet in the carbs to finish things off! I've got a similar thing on the cards for my ZRX1200 (which appears to use the same carb bodies) later this year so this video is perfect for seeing how the necessary bits come apart. :) Thanks Del, I'm looking forward to the next one! :D
That filter arrangement is a really bad design, you would have thought that Triumph would have designed a small removable cover on one side of the air box to slid the filter out, it takes me 30 seconds to change my 1976 Honda 400s air filter, I was amazed to see how clean the carbs were, good thorough job as always, cheers Del ⚙️🔩🔧👍
Hey mate, loads of useful parts on Wemoto, service kit and consumables, also a few options on TEC Bike Parts for accessories in their 'universal section', other than that it's random search online as with any 20yr old bike!
If you mean separate pod filters, then they're always backward step, ask any tuning shop and they'll always agree that an air box is king... it's actually not that hard to undo a dozen screws and pull the carbs out, it's just laziness, because it's a little harder than normal and yeah, I'd kinda like to keep the engine standard, just freshen it up and upgrading to coil packs!
Del, I've been subbed to you for several years now and just wanna say how much you help, the little tips here and there are so useful and help so much, I've learned so much from you over the years and I just wanted to show you a bit of support haha, love you man great vid as usual :)
Thanks so much buddy, that's very kind, we just upload the stuff we do here and if there's a few tips and tricks in it you can use, that's great! That's the great thing about You Tube we can share what we know and help each other out, so glad to hear you've made use of it and appreciate your feedback!
I have an Adventurer (1999) that I'm working on now. The slides seem extremely worn on the wings. It really seems like a poor design to me. Also, my bowl float cutoff seats are stuck as well. Arrrgh.
I've been loving the design of this Triumph, right up until this air box.....what a terrible design! Clean air, clean fuel, and regular oil changes seem like the very basics of maintenance, and if a builder makes that difficult to do for the owner, then it just seems like they're setting themselves up for a poor reputation! Good to see you got it sorted! I can tell you that at my basic level of skill, getting that Carbi service done correctly would have had me sweating!! Cheers D & P....ride safe!
Hi Allen, good to hear from you Sir!... and yes, it does seem a bit daft, but looking at it, with a bit of history as your background, you can see that the bike is basically trapped in time!... We have the spine frame design to echo the golden days of Meridan where that spine tube held the engine oil, but with modern carburation, they need a big plenum type air box so had to design it in around the historic frame... with the result, they built a bike around the air box lol Have a great week, keep safe there, D&Px
You know it mate, the most backward piece of design I've seen in a long time and no doubt the exact reason why it's been left in there 20yrs to fester, but got a new one on the way!
70% of these comments are just moany, unobserved and ill informed.... did you not hear him say it ran like a watch? Floats where spotless and the diaphragms where too! Oily build up washed of with minimal effort and the pins where mint..... instead of watching these great 'Have a go' educational breakdown videos, try watching AND listening, at least these guys are doing it to help other's try. Always a great reference for these type of jobs and IF you discover your jet's need a clean....crack-on!!! He obviously said " it ran like a Watch and had barley been ran in at just 17k. Great work Del & Pen...thanks!
Thanks buddy, appreciate you saying that, personally, I got a bit tired of saying it myself cos it sounds like they're not listening anyway, but you know how it is, everyone has to have something to criticise and as soon as the next video goes up, they'll start on that one and this one will go silent... Glad you enjoy the videos, we both appreciate it.
The air box has crank case breather hoses fed in to it in order the re-breathe engine discharge vapour through the exhaust, and over the years, this poisonous mix of oil and fuel vapour eventually breaks down the foam, plus it's helped by pure age, just look at the foam in a seat if it's 20yrs old!
Makes you Yearn for the Oldies EH?? .... Apart from the reliability of course ... But wasn't that the fun? ..... Having to get the Tool-wrap out at least once a week :-)
I would have blown out the jets but you probably did. Ultrasonic cleaner was great for my old Kawa GT 550 jets. Highly recommended. Sometimes jets look clean but aren’t. Hope you find a decent filter to replace the crap that came out. What a poor design from Triumph.I hope today’s design is more customer friendly. Keep up the great work.
Now, in the land of hydrocarbon bar flies, that's what I call an optic rack of worthy intent. None of your 'airy fairy perfume counter test sprays with some Amal-rejective 'puter saying 'enough already' all the time, these guys are the full Olly Reed, three most worthy decanters for a customer driven frenzy at anyone's opening time . . . but that 'crouching Doctor, hidden hamster' airbox does smack of a 'just fit it & get it out the door' sense of demand for the finer details of development. Thinks: Could the motor swing forward a tad with a top mounting off - or didn't the dealers have a 'cunning plan' either? 'Kinked headers Sir? - yeah, they all go like that . . honest' : ) xx
Another educational video, thanks. In the near future, I hope to buy a 1981 Suzuki Katana. However, this bike hasn’t started in 18 years, so this and the next videos are very timely.
Excellent video yet again it's been that long since i had clean a carb I'd forgotten what they looked like on the inside lol looking forward to the next one enjoy the rest of your week as always ride safe both of you
Cleaning the jets? Ok... maybe not but what I can say after rebuilding my own carbs this past fall... to all those quoting aftermarket carb rebuild kits?? Do NOT buy aftermarket kits. I did this and after almost three days of installing cleaning and reinstalling and inspecting etc I finally had to take it to a mechanic to find out why it wasn’t running on all cylinders. I had checked EVERYTHING. He looked into it, replaced the aftermarket pilot jets with the originals and voila. Problem solved. Told me this happens all the time with aftermarket kits and the pilot jets not being correct pitch and so forth. Cost me $500 to find out that my $100 rebuild kit was scrap. So... word to the wise. Ante up and buy the OEM jets.
A valuable lesson there and so many times it is important that if something's working just right to leave it alone, so many people insist on stripping and fiddling and making them worse for it, like some kind of OCD, but in the real world a perfectly balanced and well functioning set of carbs is a rare thing and if they're all good, like these are, then leave them alone.... and you're so right, pattern parts can often be the route of further problems in so many cases... take care there buddy, keep well, D&Px
@@Moonfleet41 Agreed with the leave it alone concept. My needles on #1 and #2 cylinder we worn so had to replace some components. The needles were essentially the only thing that worked out of the kit.. oh... that and the new screws. I never replaced the main jets as they came from a dynojet kit.
Nice one Del! The std Triumph air filter for the TT is all one unit. I had some customers split them and fit an aftermarket filter, but they did not always reseal properly and ran poorly as a result, requiring another strip down. I think it was to be replaced every 12k or two years but gen filters are now £60+ so a few take a chance.
You didn't clean the jets???
I like everyone else are surprised you didn't do the main and idle jets and needle and seats as well as the air mixture screws!

I love these gritty videos Del, they take away the overwhelming feel to any jobs on a bike and educate the self confidence to have a go yourself. Within reason ofcourse 😌
Del,
Since you're leaving the stock air box in place and having made a custom exhaust, do you expect to have to rejet the carbs with the change in exhaust? Keihin carbs on Triumphs tend to be really finicky and any change in either intake or exhaust and they don't seem to run properly.
I have a 2000 T'Bird std and while I don't mind the stock airbox, other than it looks really clunky, I would like to change out the peashooter exhaust for both look and sound. But, I really don't want to have to rejet and resynch the carbs.
Thoughts?
I won't know at this point mate, I may do, I may not, I'll find out when I get it back together and run the engine, at the very worst there might be a faint possibility I have to fit a dyna jet kit, which is no great shakes aye!
I’ve just been through the carbs on my 1998 Thunderbird Sport, ended up replacing the stock air box with individual pod filters and rejetting the carbs.......it runs a lot better plus removing the carbs is a 5 minute job.
I did the same. The intake noise was worth the effort alone
Hi Delboy, great video, I have a Triumph Thunderbird Sport with Keihins, the throttle slides do look a bit scored on mine, but all three do move easily enough when assembled,. However they do seem quite loose in the slides, and bike misses like hell, more so at low revs, and not too bad if throttle kept still. But as soon as its turned, big misfires and flat spots.. year 2000, 36k...any suggestions.. thanks
Del good vid. I was a carb fitter many years ago, did cars, boat, bikes, and specials. You will find on most occasions it,s the rubber parts that will give you trouble. ie leaks air and fuel. In high mileage vehicles excess throttle spindle play will cause poor running and impossible to set up. we used to re bush the body of the carb, nowadays it will probably have to be replaced. As for jets very rare for them to block as most vehicles have a fuel filter, more likely that a crankcase breather will cause carbon build up on a slow running valve or similar device that uses crankcase vacuum. You did worry me as you had the float chambers off and didn't replace the RUBBER seal/gasket,You will probably get away with it as low mileage bike. Chances are if gasket is slightly proud of float chamber you will get away without replacing. Also did you check the needle valves ? Not good Practice LOL! Please don't think I,m having a go at you. I love what you do and you helped me with disc bobbins, so trying to help you back.
Cheers .
I'm sure you saw how spotlessly clean those carbs were mate, and I do feel that listening to the blather from some people, that they're not satisfied till you tear everything single component apart but the simple fact is, this bike is barely run in, like you said, low mileage and a fuel filter in the line, they were spotless, just a little oily build up on the back of the slides which washed straight off, as you saw too the diaphragms were perfect, like new, and the bowl gaskets were nice and proud plus quite soft still.. this is a well cared for bike and when I rode it in, it ran like a watch!... so like the old guys say, if the cart ain't broke, don't fix it! Thanks for your insight mate.
Nice video Del & Penny. That air cleaner has seen better days and I can see why, not the best bike to do a a fast filter change on lol. Penny and you have a great week. Cheers
haha yes indeed, I don't think that would be a race pitstop item! Good to hear from you mate, have a great week, D&Px
Very good video as usual, there are two things I would have added. Like some other comments say, I would have taken off the floats and cleaned the valve seats also have checked the jets. It's easy enough and while you are in there??? You also sprinted past the need to synchronize them with a quality gauge.
Secondly, I have found that with CV carbs it's important to check the diaphragm for any sings of old age. I usually pull them out and hold them up to a strong light source and look for pin holes or any cracking or brittle areas but other than those two pet peeves of mine I liked the video. I find myself hooked and once I start watching I can't stop! Thanks and keep up the good work.
Did you maybe skip through the video by any chance, did you not see me remove the diaphragms, check them close up one by one for cracks and perishing, check the needles for wear?? I'm curious as it seems bizarre that you would criticise something I did in detail and showed in the video, check again 7:03
@@Moonfleet41 I recall you cleaning the needles but I didn't hear you say anything about the diaphragms...sorry if I missed. I do have a question......I have a HD customer who also has a Trimuph. A 2013 America complaining of rough idle at start up, and long warm up times before it will be happy with no choke. He said the last shop just had to clean out the little hole???? And that helped. If I do decide to pull them clean an sink em do I need a special fitting on the vacuum access, or is it just hose to vacuum port? I think they are Kehins I aint had it in yet though. Any info on that model would be helpful though.
@@Moonfleet41 ok you did say the diaphragms were perfect, but you didn't say how you came to that conclusion. Think if that was your only MC and you never cracked open a CV carb...you see what I'm getting at.
Hi! What grease do you use for the gasket.?
Just regular LM grease.
@@Moonfleet41 Ok! Thank you😊 another question. Are the carburettors on your triumph thunderbird the same on my triumph adventurer 1998 maybe? I'm thinking about to clen my carburettors and dont know what renewal kit to buy. They look similar to yours. On my bike there is keihin cvk carburettors.
Your methodical step by step approach will surely have given those previously "afraid" of attempting such a task the confidence to give it a go Del - in my opinion exactly what TH-cam is all about - great job - thanks as always for sharing!
He didn't do anything lol 🤔????
@@garethross6258 - I am an auto electrician working on HGVs - my biggest challenge is always "getting to the fix" - especially considering they way in which modern trucks are put together - what Del has done here is equip people that don't pull bikes apart on a daily basis to "get to the fix" - it's then down to them in how far they go - dependant on the issues they find - in my humble opinion - a valuable and informative video - and it would appear that as it stand currently - 836 people agree with me? Thank you however for giving your consideration to my comment - I look forward to watching your video showing how it should be done - please feel free to post a link to it when it's ready to view. God bless you and stay safe!
@@mikeopenshaw9128 not my vid no... but one of the better ones and very much more in depth and informative towards cleaning and rebuilding carbs... all Del did was clean the bowls and slides lol... Was a video necessary for that? And he said he was going to be cleaning out the jets? He did not go near them? You best read all the other comments and watch this video yourself
th-cam.com/video/95nlrP-yn2I/w-d-xo.html
Hi. Please can you tell me what the red sealer you used on the float bowl was? Thank you.
Not sealant, it's silicone rubber grease to help the rubber seals seat and work at their best.
Thank you.
Hi Del- after a long, tough day it was quite nice to put my feet up and watch this vid. Hard to believe that Triumph designed such an odd aircleaner mechanism. Indeed, no wonder the original filter was still in there! Good to see Penny 2:29! Hope you both are doing ok. 🏍👍🏍
Hi Gary, always good to hear from you and we're glad to hear the video gave you a little lift after a stressful day... you both take care there and keep safe, D&Px
@@Moonfleet41 you guys are the best! 😎
@@garya3056 Very kind of you Gary, and we really appreciate your support!
@@Moonfleet41 👍
Not sure that is the origal air filter. From memory the air filter and box are sold by Triumph as a 1 piece unit (ie, to replace the filter you replace the box). Hence most people replace them with aftermarket filters.
From what i can find out, the original filters were made by Pipercross, and that's the only one single filer i could find for sale.. !!
@@Moonfleet41 , think ours was paper as standard, inside the box. Replaced with a K&N because I object to throwing the airbox away to change the filter!
Recently bought a 99 Legened as a do it up as I go along job. So unfortunately can't go full project bike. These videos are invaluable so thanks. I'm from Hinckley originally so always wanted a Triumph. My only criticism of the Legened is the Air system! I mean WTF! As I am going to have the cards of to sort the air filter will give them a dig out. Seriously thinking of putting pods on to 1) save the hassle and 2) free up a shed load of under seat space!
Anyone an idea of the jetting for pods? (I know it depends on the pod, but a ballpark would be nice).
What you used in the float gasket? Is something red
Nice work . Takes me back to when I had my bike . Always doing something to it 👍👍👍
Hi, I bought a legend with no carbs, you think that a carb from thunderbird, trophy ot spinter would work? thanks!
Are you planning a carburetor synchronizing?
Did mention it in the video!
Just a thought will the rubber grease you youse interfier with the petrol dell
Loving the legend but I have to agree with the other comments about not cleaning the jets. I hope you also cleaned the duckbill filter in the fuel line which must have picked up some crud over the last 20 years.
And if you're going to run a less restrictive exhaust than standard, you'll want to take the idle mixture screw 2.5 turns out or you will get excessive pops and bangs on the overrun. Once the carbs are back on the bike, they're nigh on impossible to adjust.
My old Ninja 250r would get what I called "carburetor slide slap" after 5-10K miles. The slides would rattle back and forth, making a rhythmic tapping noise at idle, but disappear when throttle is applied. I eventually isolated the culprit with a mechanic's stethoscope. As far as I could tell it was harmless, but it happened over three different carb sets (kept buying more when I was young, dumb, had OCD about every new noise, and threw money away). I'm assuming this is pretty common... ever hear about or experience this?
I don't know what carbs they used on that bike, but the Mikuni flat slides I put on my old GSXR years ago used to clatter like castanets on tick over and it was quite normal, and like you said, went away with a tiny bit of throttle, basically they were just bouncing off their seats on idle!
What is your handlebars? Where you bought it ?
Hi Del, the carbs don't look to dissimilar to the ones on a GSXR 1100 from the 90's. i used to race F1 sidecars and used the 1127cc suzuki motor, a dynojet kit will transform the fueling if your budget allows. Another tip with this type of carb is to check all three float bowls all sit at the same height as the brass holding arms can weaken over time. If I was still in the UK i would buy this bike off you in a heartbeat.
Hey buddy, you are very perceptive, those carbs are exactly the same as the CV flat slides used on the 1127, just one less obviously! And I was surprised how clean they were inside, as for sale when the time comes, be happy to ship it, already had a couple of requests so it may be well worth considering?!
Not sure what your name is but, I’m glad I found your Channel. I think you’re awesome Bike mechanic. Your attention to detail is awesome! Now if you can just come to Oakland, Ca and help me with my 2000 TBird Sport that would be great 👍 Thanks..
Thank you for your kind words Dan..
Which costs more, your bike projects or T-shirt for rag expenses 🤣 another great and informative video, thanks.
Those compressed bags of rags cost £10 and last 18 months or more.. great valuer buddy.
Very nice video! I am considering using Triumph carbs on an old Yamaha triple. I noticed there are two tubes for fuel near the bottom of the carbs but what are the two tubes near the top of the carbs used for? Are these vacuum lines or just vent lines that exhaust to atmosphere?
We miss Penny!
Hi, maybe you know, maybe it's mentioned in the comments below, but; a lot of people make a side entry on the airfilter box to simply remove/clean/ replace the airfilter.
Cheers from Holland. Sold the bonnie, but it was a blast working on it with your tips and tricks as back up :)
That's great to hear, am glad you got it fixed up, always good to move on to the next one!
The tbird carb removal is a little easier than the other models of that era. A bit more clearance? I would've changed the o rings as a precaution? They harden,and crack over time,and readily available on eBay,and not really expensive 👍
Hello, how can i contact you. I have a 2000 thunderbird 900 and when i start it it surges and hang.
Del... Another awesome video. I would say you are lucky. I have never had the screws come loose that easy especially the float bowl ones. They are usually all striped out and I have to come up with clever ways to get them out.. Great job!!
I think you're right mate, I did feel blessed at how well that went I have to say, I think it's a testament to the fact that they've probably never been apart, so the screws weren't pre-chewed!
OEM Air Filter manufactured by Pipercross that is 👍 Bet it hadn’t seen the light of day once in the 20 Years it was in there.
Totally agree mate, that foam literally broke apart like stale cake... I've a new Pipercross filter on the way!
@Shed Life Yes indeed mate, it is often a little smoke and mirrors in some places, and many techs will know the sinking feeling of having to get work done on a stopwatch when there isn't enough allowance to do it properly!
Got a link to the torque Allen T heads you use?
Do you mean the torque wrench T-bar?
Non virtual Video without a Black and white workshop manual 😉 📚 .
Love watching all your videos Del, but is there a reason you didn’t strip & clean the jets & float valves?
Did you see how clean those carbs were mate? Absolutely spotless, like brand new inside and the bike ran like a watch, like they say mate, if the cart ain't broke, don't fix it...!
@@Moonfleet41 True ......BUT.....the carbs should have been built for the NEXT 17 years of service. Carbs should have been properly cleaned and new rubber parts installed.
That's like saying that you never have time to do it right but always have time to do it twice?
Dell you work like a Swiss watch yourself excellent work
Thank you kindly, appreciate your kind words, it's a labour of love!
thx a lot for share , this is the vid that i was waiting for , i have a legend tt , with the carbs out of the bike , i will cleaned and wait for the sync video , i had a lot of problems with this carbs with and without the air box , currently i have just the airpods due i lost the air box , but anyways , thx a lot !!!
I cant believe how rotten that filter was and the engine was running ok, the motor will certainly like a new filter. Great video and nice to see some carbs. Kind regards mate.
Cheers buddy, you're right, I think that filter was made by Mr Kipling, but the new one has arrived today, so all good to go... hope you're enjoying the Harley mate!
Thanks Del, I’m really enjoying the Harley, I’m astounded how comfortable this one is, I’m only in running in mode and on small milk runs but i can feel its pretty quick. I love it.
Hey Del, terrible air filter box design... I thought my bandit was a PITA because I have to remove the gas (er, petrol) tank... Next time I do it I will think of Triumph. Thanks for the video.
Sure thing mate, think of the poor old Suzuki GSXR that inspired the Bandit, the early 1127 models you almost had to take the engine out to get the air box removed!
crank case "vent" back into the airbox allows oil vapors to accumulate too.... I never liked that idea to begin with...
Yeah, in many cases if directed the crank case breathers into a catch tank..!
So I'm also intrigued that you didn't clean out the jets... however, since you've installed custom headers and since you're installing a new air filter, I'm going to hazard a wild guess and predict that we'll be seeing a cheeky little K&N number going in that airbox (or possibly even a sweet set of pods and an airbox delete) with a naughty little rejet in the carbs to finish things off! I've got a similar thing on the cards for my ZRX1200 (which appears to use the same carb bodies) later this year so this video is perfect for seeing how the necessary bits come apart. :) Thanks Del, I'm looking forward to the next one! :D
That filter arrangement is a really bad design, you would have thought that Triumph would have designed a small removable cover on one side of the air box to slid the filter out, it takes me 30 seconds to change my 1976 Honda 400s air filter, I was amazed to see how clean the carbs were, good thorough job as always, cheers Del ⚙️🔩🔧👍
Hi del, great to follow along!!
QUESTION, what’s your preferred sites to order TT and Adventurer parts?
Hey mate, loads of useful parts on Wemoto, service kit and consumables, also a few options on TEC Bike Parts for accessories in their 'universal section', other than that it's random search online as with any 20yr old bike!
What is that red/purple stuff you put on the seals of the throttle bodies?
Red Rubber lube mate.
@@Moonfleet41 thanks
When you do carb sync could you do a good "how to" video? I could do with proper understanding of how to and how it works, thanks
Can we install kicker in triumph Bonneville T120
On Trophies, people cut the airbox in two, so each side can be removed, and access to the air filter is easier.
I wonder if their is an upgrade to the air filter so you can get rid of the box and better performance unless you want to keep it original.
If you mean separate pod filters, then they're always backward step, ask any tuning shop and they'll always agree that an air box is king... it's actually not that hard to undo a dozen screws and pull the carbs out, it's just laziness, because it's a little harder than normal and yeah, I'd kinda like to keep the engine standard, just freshen it up and upgrading to coil packs!
Hi ,do you think these older bikes are a good buy and a nice bike to ride ? as I have been thinking of one ,nice video . Thank you .
A man who owns his bike...does what he wants. Thanks for the video
Wise words well said.
That whole assembly must be restricted between the air box and the ‘leaf collector’.
The link pipe is only about the size of one carb intake.
Is any 'non ram air' system any bigger than that in the main inlet !!? Not usually !
Del, I've been subbed to you for several years now and just wanna say how much you help, the little tips here and there are so useful and help so much, I've learned so much from you over the years and I just wanted to show you a bit of support haha, love you man great vid as usual :)
Thanks so much buddy, that's very kind, we just upload the stuff we do here and if there's a few tips and tricks in it you can use, that's great! That's the great thing about You Tube we can share what we know and help each other out, so glad to hear you've made use of it and appreciate your feedback!
I have an Adventurer (1999) that I'm working on now. The slides seem extremely worn on the wings. It really seems like a poor design to me. Also, my bowl float cutoff seats are stuck as well. Arrrgh.
I've been loving the design of this Triumph, right up until this air box.....what a terrible design! Clean air, clean fuel, and regular oil changes seem like the very basics of maintenance, and if a builder makes that difficult to do for the owner, then it just seems like they're setting themselves up for a poor reputation! Good to see you got it sorted! I can tell you that at my basic level of skill, getting that Carbi service done correctly would have had me sweating!! Cheers D & P....ride safe!
Hi Allen, good to hear from you Sir!... and yes, it does seem a bit daft, but looking at it, with a bit of history as your background, you can see that the bike is basically trapped in time!... We have the spine frame design to echo the golden days of Meridan where that spine tube held the engine oil, but with modern carburation, they need a big plenum type air box so had to design it in around the historic frame... with the result, they built a bike around the air box lol Have a great week, keep safe there, D&Px
@@Moonfleet41Thanks for the history, makes a lot more sense knowing that! Cheers!
This air filters change on a 885 engines are considered like "winter project" by Triumph 🤣🤣🤣
A great way to spend this morning with a coffee watching you work👍
A common mod is to split the rear half of the air box so you can remove it with the carbs still on.
Remove the carbs to change the air filter? Wow, and I thought Harley was daft!!
You know it mate, the most backward piece of design I've seen in a long time and no doubt the exact reason why it's been left in there 20yrs to fester, but got a new one on the way!
70% of these comments are just moany, unobserved and ill informed.... did you not hear him say it ran like a watch? Floats where spotless and the diaphragms where too! Oily build up washed of with minimal effort and the pins where mint..... instead of watching these great 'Have a go' educational breakdown videos, try watching AND listening, at least these guys are doing it to help other's try. Always a great reference for these type of jobs and IF you discover your jet's need a clean....crack-on!!!
He obviously said " it ran like a Watch and had barley been ran in at just 17k.
Great work Del & Pen...thanks!
Thanks buddy, appreciate you saying that, personally, I got a bit tired of saying it myself cos it sounds like they're not listening anyway, but you know how it is, everyone has to have something to criticise and as soon as the next video goes up, they'll start on that one and this one will go silent... Glad you enjoy the videos, we both appreciate it.
Thank you...
my air filter was the same had not been changed from new but i did manage to replace it without removing the carbs but it was not easy and took time .
What breaks down the filter like that? Stale cake lol
The air box has crank case breather hoses fed in to it in order the re-breathe engine discharge vapour through the exhaust, and over the years, this poisonous mix of oil and fuel vapour eventually breaks down the foam, plus it's helped by pure age, just look at the foam in a seat if it's 20yrs old!
@@Moonfleet41 yea true over time the foam deteriorates. Thats an interesting air box!
Makes you Yearn for the Oldies EH?? .... Apart from the reliability of course ... But wasn't that the fun? ..... Having to get the Tool-wrap out at least once a week :-)
I would have blown out the jets but you probably did. Ultrasonic cleaner was great for my old Kawa GT 550 jets. Highly recommended. Sometimes jets look clean but aren’t. Hope you find a decent filter to replace the crap that came out. What a poor design from Triumph.I hope today’s design is more customer friendly. Keep up the great work.
Thanks buddy, found a Pipercross filter for a good price, and half as cheap as a genuine one!
Good one Del
Now, in the land of hydrocarbon bar flies, that's what I call an optic rack of worthy intent.
None of your 'airy fairy perfume counter test sprays with some Amal-rejective 'puter saying 'enough already' all the time, these guys are the full Olly Reed, three most worthy decanters for a customer driven frenzy at anyone's opening time . . . but that 'crouching Doctor, hidden hamster' airbox does smack of a 'just fit it & get it out the door' sense of demand for the finer details of development.
Thinks: Could the motor swing forward a tad with a top mounting off - or didn't the dealers have a 'cunning plan' either? 'Kinked headers Sir? - yeah, they all go like that . . honest' : ) xx
In fine voice you lyrical gangsta!
Another educational video, thanks.
In the near future, I hope to buy a 1981 Suzuki Katana. However, this bike hasn’t started in 18 years, so this and the next videos are very timely.
Best of luck Gareth with your new project!
Thanks man !
Excellent video yet again it's been that long since i had clean a carb I'd forgotten what they looked like on the inside lol looking forward to the next one enjoy the rest of your week as always ride safe both of you
Thanks Malcolm 👍, you too, have a great week!
TOP TIP ..whenever I park my bike I always run the bike out of fuel then no gunk is left to congeal.🤓 always works for me.👍🏻
You didn't clean the jets?
Why make a serviceable part so hard to get to. Great video as always mate.
Yeah, why indeed aye mate !
My old XJR1200 manual : to remove airbox, first remove engine...!
Don’t you have to check the float level’s
Considering the state of the air filter, the carbs looked pretty good.
Indeed, I was quite surprised at that, I guess I caught it just in time before it started consuming the foam!
I appreciate the commentary at the end. very informative
Nice video good carb clean added to the Del Boy how to playlist
Cleaning the jets? Ok... maybe not but what I can say after rebuilding my own carbs this past fall... to all those quoting aftermarket carb rebuild kits?? Do NOT buy aftermarket kits. I did this and after almost three days of installing cleaning and reinstalling and inspecting etc I finally had to take it to a mechanic to find out why it wasn’t running on all cylinders. I had checked EVERYTHING. He looked into it, replaced the aftermarket pilot jets with the originals and voila. Problem solved. Told me this happens all the time with aftermarket kits and the pilot jets not being correct pitch and so forth. Cost me $500 to find out that my $100 rebuild kit was scrap. So... word to the wise. Ante up and buy the OEM jets.
A valuable lesson there and so many times it is important that if something's working just right to leave it alone, so many people insist on stripping and fiddling and making them worse for it, like some kind of OCD, but in the real world a perfectly balanced and well functioning set of carbs is a rare thing and if they're all good, like these are, then leave them alone.... and you're so right, pattern parts can often be the route of further problems in so many cases... take care there buddy, keep well, D&Px
@@Moonfleet41 Agreed with the leave it alone concept. My needles on #1 and #2 cylinder we worn so had to replace some components. The needles were essentially the only thing that worked out of the kit.. oh... that and the new screws. I never replaced the main jets as they came from a dynojet kit.
Nice one Del! The std Triumph air filter for the TT is all one unit. I had some customers split them and fit an aftermarket filter, but they did not always reseal properly and ran poorly as a result, requiring another strip down. I think it was to be replaced every 12k or two years but gen filters are now £60+ so a few take a chance.
Thanks for the insight mate, I've ordered a Pipercross and I can see from the design that it needs to be very carefully fitted to make it seal!
Is that a 36mm Throttle Butterfly
looks a very similair set up to the sprint 900 which I have just purchased and it hasn't run for 4 years 🙄🙄see what crap will be in that lol
Good luck with it mate, have fun!
Another great tutorial. Can't wait to see this bike finished. 👍🏍️
