Finally a no nonsense approach to what should be a simple job. Managed to change sprockets in less than an hour. Longest job was winding in and out the chain tensioners to provide sufficient slack and then retention at the end of the job. I put a piece of tape on each side of the swing arm and marked in pen where each adjuster was. Made the job of re-tensioning a lot easier and more ‘accurate’😎
Thanks Dad for the comment. Simplest way forward is usually the best, especially when your tool budget is limited 😆. I shall try the trick with the tensioning in a future video 👍
Bought my speed 400 and love love love it but 100% short gearing is annoying, basically driving around everywhere in 6th and still buzzing up to 6000 RPM at 55-60mph (USA). I AM over excited that you made this video and I hope it’s the fix I’ve been searching for. Thank you
Really great info and it was so charming to see the job is actually easy if you are comfortable with basic tools. A quick question - does this change in sprocket void the warranty?
Hi Viks, I suspect not. In the world of reassonableness (which the world is certainly not in at the moment 😆 - and to be fair, has not been in it for about 10'000 years), I would suspect that all would be fine. And to be fair, there must be some 95% chance that the bike will never need to be returned under warranty - as I maintain then myself and really do look after the bikes. Never thrashed, always nurtured etc etc.
Thank you, Richard! Good to see, that - except those annoying cables- everything is quite accessible . I‘ve ordered the 15 tooth sprocket from Rally Raid in the UK and expect it to arrive any day in Hamburg. Your video will help quite a bit and I‘ll make sure to have a hammer or two at hand😊 Your follow-up video with the first 15er ride makes me look forward to this modification as well. Kind Regards from the Continent, J.
Hi J, thanks for the comment 👍. Great to see you found the video useful. No need for a hammer, use the socket wrench 😆. Sometimes, we have to do what we need to do with the tools at hand ❤
There's plenty missing from the video, hope you have the correct tools to complete the job and not just using the tools the way they have been used in the video.
Lovely job Richard.I've just invested in an Oxford Premium Paddock Stand and some 6mm threaded rod and bobbins which will make the whole job easier when I tackle this.Fitted my Thruxworx tail tidy and bullet indicators today which was very straightforward but do need to adjust my chain tomorrow as already a little snatchy after 325 miles
Hi Ged, my son has the paddock stands and was going to use them but thought a blast back to when we were not so rich would be a good show 😆. Took the 400 up the motorway yesterday and made a video. The 15T works well with a buzz at 70 which clears when pushed up to 80 (on the dial - probabaly about 72mph true). Well done on the tail tidy. I should think about doing the same as the back end, like most bikes today, have this strange rear end. I am thinking of fitting the scottoiler to the 400, in readiness for winter. That should be interesting 😆
In March 23i bought my GoldStar Midnight Black for £6800 + otr yesterday i visited the Honda dealer and tried the DCT NC750X which is getting up towards 9 grand. My GoldStar has 675 miles on the clock and thanks to BSA knocking £1500 off the cost i realised i would take a hit but the size of that hit astonished me, I was offered £2600. I can't afford to let it go and take such a loss I'll have to keep it.
OMG Ian, I am sorry for you. 2600 is a hell of a hit. That said, I think the GS is a wonderful bike. Having spoke to Triumph, their second hand sales have collapsed. Only new is selling. I can only suggest putting it on Marketplace for the price you want - whilst we are still in summer. You may well get the price that you would be satisfied with. To be fair, it has low mileage so that is on your side for the potential buyer 👍
Sadly I think many people got caught up in the social media hype when this bike came to market, especially in the UK, and now it seems to have virtually dropped completely off the radar.
That was a good way to do this job Richard , we aren't all situated in a nicely equipped workshop. The only thing i would do differently is add a little blue locktight on the sprocket shaft thread as there seemed to be some when you removed it and the other was when retensioning the chain i would spin the rear wheel to find the tight spot in the chain and then adjust to get the 20 - 25mm slack in the chain. Good stuff i look forward to the next one
Damned it Gordon 😆. Bloody good idea regard the locktight. I shall do that this afternoon 👍. Thanks for the reminder. And checking the chain - took it around the block and did check but a very valid point 👍 Thanks ever so 👍
Thanks for taking your time Richard in the video. I would like to see a video in review of what your decisions were based around in why you decided to get rid of the 2 bikes that you recently sold. Especially the BSA. It seems like since you purchased the Triumph T-120 that your excitement for the Goldie just slid of of the cliff? I respect that you made the decisions that you did & was just curious as to why? Have a wonderful day! Cheers!! Illinois, USA
Hey Larry, good to hear from you again 😄. I have had to perform a few changes in anticipations of storms ahead, controllable storms but nevertheless. I was talking to a group yesterday, on our ride (me on the T120) to a small place called Monyash, in Derbyshire. Popular place where walkers and riders meet for coffee and breakfast etc. Explained the situ on the BSA and the reasons for the sale along with an ongoing (for some 6 weeks) issues from the new owner. Got to the point where I had to block the new owners number. That was a week ago. It'll come out in the wash I guess 😆. So, I have one video that keeps being scheduled for the future - and then gets rescheduled again for a further future date. I should let this video just go. And then create a simple video on the sale of the BSA on the issues of such sale over the past weeks. Two sides on that story I guess, 1, the sellers perspective, and 2, the buyers perspective. I am going to have to think about this one 😬. Thanks for asking and it was this comment from you that 'instigated' the conversation today at Monyash. Let me sit and think about this 👍. You take care my friend 👍
@@bankruptpensioner Yea- sometimes it's fun to be an instigator!! (LOL) Your kind of like reading a book that dropped a couple chapters or so. Have a good one mate!! Cheers!!
This job is a lot easier if you lift the bike up on a paddock stand and loosen the chain much more and use an impact wrench for the nuts. I just completed a 17 tooth sprocket install on my Tiger 850 sport and it was a breeze.
Did my Tiger 850 about 6weeks ago, interesting results. At first I thought don’t like it, 6th gear is very much an overdrive and the bike just seemed to have lost its pep! However I’m now used to the different riding techniques and on balance prefer the more relaxed feel of the engine on dual carriage ways and fast A roads. Fuel consumption has improved more the I thought it it would, by about 4mpg. The slight vibrations, which I love, are now lessened at faster cruising speeds making it better for riders who found it aggravating. What are your thoughts?
@@MichaelWilliams-jc2ui Hi Michael, same principles as the 400. Not sure why this is not adopted as standard however, it's good that you feel your 850 is better or different in a positive way. More MPG is always welcome. Less vibration too 👍. If it makes 90% of your riding better, then you are on a winner.
Hello, if you place a smaller sprocket you will make it lose torque and increase speed. In this case, what is the goal of changing the sprocket? I have learned that the air filter and the oil filter are also compatible with KTM’s Duke 390. Do you know anything about that? A greeting
You have a pretty good video here but you make it seem a little easier than it is. I had a long breaker bar on the countershaft nut and couldn't break it. I am lucky to have a small auto repair shop at the end of my street. I took the bike there and the tech put an air wrench on it. The real problem right now is to find the damn sprocket. I can't find one in stock anywhere. I could sure use some part numbers as I have already wasted some money on a KTM 690R sprocket that doesn't fit. Triumph doesn't have it, JT is out of stock. Can anyone help?
Hi David, just had a look on eBay. This is the sprocket you need - same as the KTM: www.ebay.co.uk/itm/225502977245?_nkw=jtf1908&itmmeta=01J5ZB61T815TYZ7HRH826J99P&hash=item3481065cdd:g:Ws4AAOSwx1BkJcF2&itmprp=enc%3AAQAJAAAA4HoV3kP08IDx%2BKZ9MfhVJKkkqgn3JgntQNsjA64azSIc6ky7FJDSDeaVZdfn5ZRzzsCbtkvrsW%2B9dNV%2F9jctUqTAmYRmd0iRY89dobdOck9vI%2FcmTFVYm1k83dH4fuH3RYoxnBN0c7cwHnc--H4jkej%2Bhw%2BvTVnhoonc7eMwERLfaCzfFwnqjxsrL5V%2F59JwuJdTCK9KRqllR9DlGDiTrYeZS3LdepvOHzQMut6n4Fo8ZV1gLfeH%2F5XNvSdO44k30b4Vwnopclrt8p7E341REFakMkGfkkkVkpDpwDq3Uz9n%7Ctkp%3ABFBMnp2Y669k Hope this helps 👍
@@dannyvan5792 completely understand. But to be fair, hitting the tyre with a wrench has no more impact to its structure than where the tyre is designed to be used, not even considering the potholes on the roads 😂😂👍.
Hi, nice job! Could you share with us te OEM part number code of the sprocket? I Guess it's JTF 1908 15 RB, but its hard to see clearly in the video. Thanks!
Nice vid... many thanks, I've ordered my 15t sprocket from Tec, once the first service is out of the way I'll be swapping it out... are you going to do a comparison vid after fitting it...??? I think a paddock stand would've helped with the back wheel and slackening off the chain, but I guess not everyone has them... thanks for a great vid, Ride safe H
Hi H, thanks for watching 👍. Yes, a test review is coming in a couple of days so keep an eye out. Overall, this extra tooth has changed the persona of the bike. It’s the best value for money I have spent on the bike and when you are ready, you should change over. The extra tooth stretches the gears to how they should be and it really does feel better 👍
@@bankruptpensionerdoes the 15t sprocket lose some of the acceleration punch below say 50mph, fir the sake of a higher top speed. ? I’m using mine as a city/ traffic commuter and need the sprightliness away from traffic lights and roundabouts and dopey drivers. !!
@@chrro466 That is a great point - but in all honesty, taking the time out from having to change gear two times (first to second to third) and now only having to chnage once (first to second) offsets the reduced accelleration MAYBE 😆. Good point though. I understand city riding, and the need to be able to accelerate away from traffic. The 15 tooth may well offer the same performance but without changing gear so much??? Not sure on that. 😆
Hows the speedo error after the sprocket change is it cliser to true? As i find it reads a good 10% over and the mpg same. Personally i would have marked the adjuster bolt heads with a permanent marker and noted the number of turns to ensure even adjustment and of course torqued up all relevant nuts to spec might even have splshed out on a new lock washer.
great advice on the marker Anthony. Good call 👍. I understand the error in the speedo is literally there....and as the speed is taken from the read ABS ring, the change on sprockets is irrelevant on this matter. A bigger rear tyre would help remove the issue with the speedo - maybe thats the one when the bike needs a new set 👍
My owners handbook has the chain free play missing (p108), it says "The vertical movement of the drive chain must be in the range of for the Speed 400 and for Scrambler 400 X" I emailed Triumph, Freddy from aftersales said: 20-25mm Speed 400 40-45mm Scrambler 400x
Hi Andy, many thanks for the $ like. Much appreicated. I will remember this for sure ❤. Adidas - Hamburg in red of course 😆 images.app.goo.gl/x8NWYb2ZdP5znh4n8
Hi Peter, no, not at all. I understand the speedo is taken from the ABS ring of the back wheel. I know what you you mean thought, but in this case, no. On other bikes, this way well be the case but not on the 400X 👍
Hi Malcolm, you are right. I used a ring spanner to get behind the sprocketand tapped the other end of the spanner to loosen the sprocket. Took about 10 mins but it was quite tight. The replacement sprocket went on the shaft easier than than the 14 tooth off. 😆
Bending flat the sprocket nut retaining washer. Precision screwdriver + ratchet wrench rather than cold chisel and hammer. Modern bikes are far too complicated for the unsophisticated bodger like me.
@@bankruptpensioner Ever had a song you couldn't get out of your head? Thinking of Trini Lopez's 'If I Had a Hammer'. It reached #3 in the early sixties.
Hi Lexico, in the case of the 400x, first and second gear are very low. The gears quickly run out of speed, so, you set off in first and within a second, you are hadning to change up to second gear and again into third. To stretch the gears out a little, you can add one tooth at the from or put a sprocket on the back with fewer teeth, It's the same principle. Its all about rations between the teeth of the fron and rear sprocket. Also, by putting an extra tooth on the pront sprocket, the bike may go a little faster. However, I am not too bother about this. Hope this helps 👍. A really good question 👍
Bonjour Phillipe, le pignon plus gros fait descendre un peu les régimes et allonge les changements de vitesses. Plus adapté à la route qu'au tout-terrain. Je ne serai pas trop hors route et si je le suis, ce sera de simples routes en gravats plutôt que des rochers et des sauts. J'ai testé le vélo hier sur autoroute et il tient mieux à vitesse maximale avec ce nouveau pignon 👍
Hi Mark, yes thats a good idea however, I understand if you put a 16 on the bike, the ECU starts to throw an error to the rider. I have heard this but have no evidence that this does happen. Is your Speed running a 16 tooth?
I think you would be best to leave your bike alone no torque wrench over tightening is just as bad as under tightening you need to do it right or not at all
Maybe you can do it yourself but in your case you shouldn't. Nothing torqued to the correct value, these are all crititcal parts. I hope anyone following this video doesn't have an accident. Good help anyone who buys the bike after you.
You bloody bodger, get a hammer and cold chisel to bend those washers! You did check the chain for the tightest spot(s) before tensioning it didn't you? Did you put some weight on the seat while tensioning it too? Of course you did 🤣🤣 Good job. Your greasy fingers made light work of it. Should do the ton down the by pass now mister, flat on the tank!
And it's not too difficult to make a simple puller to draw the sprocket off easily and evenly. Don't encourage him to ton up, even down a steep hill with a following wind. The rozzers will confiscate his licence. A bankrupt, banned pensioner would not be nearly as much fun.
It's your bloody fault that everyone is calling me a cowboy 😥.......😆. I am broke - I can't afford a cold chissel or i would have used one 😆. It was only two years ago that I was sleeping on a park bench drinking from the puddles on the ground 😆. I shall have to test it she reaches a ton - on a private road of course. Then you will have to have a go 😆
A basic toolbox includes a hammer. You could skip buying a sprocket you don't need and easily buy a hammer or mallet instead. You could also skip your next bike mod and buy something really useful, like a torque wrench. Under/over torquing is just asking for trouble no matter how much hand-waving you do. I hope that's your own personal bike, because doing this kind of work on another person's bike, is unethical and dangerous.
Sorry but what you showed is frightening, not using a torque wrench on these critical components is a engineering no no, if you haven’t got an appropriate tools leave these jobs to a professional. 😮
Hi David, you are right but those fancy tools are not at my disposal. We had the same approach on aero engines - just get the job done - and they never failed 😆
Bit of an overstatement there. Both these key nuts are not critical in the sense of they are likely to be loosened in use. I’ve changed many sprocket on new bikes and sometimes the drive shaft nuts is all but finger tight from the factory, it’s never come off due to the retaining washer. Overtightening is down to having having pretty rudimentary skillsets, which if you don’t have take it to your local bike shop! I would always use torque renchs on brake components and cylinder heads etc but these items wouldn’t bother. Mind you I’ve been spannering bikes for over 50years.
Finally a no nonsense approach to what should be a simple job. Managed to change sprockets in less than an hour. Longest job was winding in and out the chain tensioners to provide sufficient slack and then retention at the end of the job. I put a piece of tape on each side of the swing arm and marked in pen where each adjuster was. Made the job of re-tensioning a lot easier and more ‘accurate’😎
Thanks Dad for the comment. Simplest way forward is usually the best, especially when your tool budget is limited 😆. I shall try the trick with the tensioning in a future video 👍

Hey Cohen, you are going to notice a real change when you upgrade to the 15 tooth. All for the better I assure you 👍

Hi Viks, I suspect not. In the world of reassonableness (which the world is certainly not in at the moment 😆 - and to be fair, has not been in it for about 10'000 years), I would suspect that all would be fine.

Thank you, I was looking for that piece of information everywhere! Still, seems to be a lot of play for my Scrambler, isn’t it?
+1 thanks
What make are your shoes? They look light but tough enough for the "groundwork" involved in bike mechanics. New subscriber by the way
Hi Andy, many thanks for the $ like. Much appreicated. I will remember this for sure ❤. Adidas - Hamburg in red of course 😆 images.app.goo.gl/x8NWYb2ZdP5znh4n8
No torque wrenchs were harmed or abused making this video, OMG I wouldn't let you near a pushbike😮
hatsoff....😎👏🦾
Yippee 😆
Has it altered the speedometer reading.
Hi Peter, no, not at all. I understand the speedo is taken from the ABS ring of the back wheel. I know what you you mean thought, but in this case, no. On other bikes, this way well be the case but not on the 400X 👍
Thanks
Thanks Andy, like I said, you have no idea how much this means to me ❤ I won't forget 👍
You didn't show how you got the sprocket off I had to borrow a pully puller 🥵
Hi Malcolm, you are right. I used a ring spanner to get behind the sprocketand tapped the other end of the spanner to loosen the sprocket. Took about 10 mins but it was quite tight. The replacement sprocket went on the shaft easier than than the 14 tooth off. 😆
What is silly is Triumph did not put a sprocket on with holes threaded for a puller!! At least the new one has them.
I am guessing the alternate sprocket with holes will costs 15p extra 😆. Poor management decissions. 😆
Bending flat the sprocket nut retaining washer. Precision screwdriver + ratchet wrench rather than cold chisel and hammer. Modern bikes are far too complicated for the unsophisticated bodger like me.
Back to the 80's when I was broke - and into the 21st century, and I am still broke 😆

What are the gains from a 15 tooth sprocket?
Hi Lexico, in the case of the 400x, first and second gear are very low. The gears quickly run out of speed, so, you set off in first and within a second, you are hadning to change up to second gear and again into third. To stretch the gears out a little, you can add one tooth at the from or put a sprocket on the back with fewer teeth, It's the same principle. Its all about rations between the teeth of the fron and rear sprocket. Also, by putting an extra tooth on the pront sprocket, the bike may go a little faster. However, I am not too bother about this. Hope this helps 👍. A really good question 👍
It's becoming a very common alteration especially for those doing mainly road miles
bjr quel gain cela entraine ? elle tourne moins vite du coup plus d allonge mais moins nerveuse ? merci de votre reponse cdlt philippe
Bonjour Phillipe, le pignon plus gros fait descendre un peu les régimes et allonge les changements de vitesses. Plus adapté à la route qu'au tout-terrain. Je ne serai pas trop hors route et si je le suis, ce sera de simples routes en gravats plutôt que des rochers et des sauts. J'ai testé le vélo hier sur autoroute et il tient mieux à vitesse maximale avec ce nouveau pignon 👍
@@bankruptpensioner super merci pour ta reponse . je vais le changer , je l ai commandé .
@@PhilippeMarot-n6q très bien. Je pense que tu penseras que c'était le bon choix👍
Yeah...!!...however us speed' riders want a 16T...I find the 15 still to short...
Hi Mark, yes thats a good idea however, I understand if you put a 16 on the bike, the ECU starts to throw an error to the rider. I have heard this but have no evidence that this does happen. Is your Speed running a 16 tooth?
I think you would be best to leave your bike alone no torque wrench over tightening is just as bad as under tightening you need to do it right or not at all
😆, you should see me work in Aero engines in the desert - no fancy tools in the sand pit - and they don't fail 😆 - just like flight of the phoenix 😆
Hello Gramps
Hi Lee 😆
@bankruptpensioner lovely bike Sir. How are you both?
@@leepearce3148 Hi Lee, trying to make in a crazy country like the UK 😆, but all in all, ok 👍. Thanks for asking 👍
@bankruptpensioner i know it's a crap hole lol.. is he camera shy?
Maybe you can do it yourself but in your case you shouldn't. Nothing torqued to the correct value, these are all crititcal parts. I hope anyone following this video doesn't have an accident. Good help anyone who buys the bike after you.
You bloody bodger, get a hammer and cold chisel to bend those washers! You did check the chain for the tightest spot(s) before tensioning it didn't you? Did you put some weight on the seat while tensioning it too? Of course you did 🤣🤣 Good job. Your greasy fingers made light work of it. Should do the ton down the by pass now mister, flat on the tank!
And it's not too difficult to make a simple puller to draw the sprocket off easily and evenly. Don't encourage him to ton up, even down a steep hill with a following wind. The rozzers will confiscate his licence. A bankrupt, banned pensioner would not be nearly as much fun.
It's your bloody fault that everyone is calling me a cowboy 😥.......😆. I am broke - I can't afford a cold chissel or i would have used one 😆. It was only two years ago that I was sleeping on a park bench drinking from the puddles on the ground 😆. I shall have to test it she reaches a ton - on a private road of course. Then you will have to have a go 😆
Sounds like a design problem to me and if so they will ALL be the same
A basic toolbox includes a hammer. You could skip buying a sprocket you don't need and easily buy a hammer or mallet instead. You could also skip your next bike mod and buy something really useful, like a torque wrench. Under/over torquing is just asking for trouble no matter how much hand-waving you do. I hope that's your own personal bike, because doing this kind of work on another person's bike, is unethical and dangerous.
You are right, but, it does prove a point that every tool has two uses :).
Sorry but what you showed is frightening, not using a torque wrench on these critical components is a engineering no no, if you haven’t got an appropriate tools leave these jobs to a professional. 😮
Hi David, you are right but those fancy tools are not at my disposal. We had the same approach on aero engines - just get the job done - and they never failed 😆
Bit of an overstatement there. Both these key nuts are not critical in the sense of they are likely to be loosened in use. I’ve changed many sprocket on new bikes and sometimes the drive shaft nuts is all but finger tight from the factory, it’s never come off due to the retaining washer. Overtightening is down to having having pretty rudimentary skillsets, which if you don’t have take it to your local bike shop! I would always use torque renchs on brake components and cylinder heads etc but these items wouldn’t bother. Mind you I’ve been spannering bikes for over 50years.
Frightening Seriously?, you must be a main stealers dream.
Give over, the torque setting will be way lower than he tightened it.
