Triumph Scrambler Speed 400 400X 15 Tooth Sprocket how to

[@surfindaddio]

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’😎

[@bankruptpensioner]

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 👍

[@johannesmarg6903]

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.

[@bankruptpensioner]

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 ❤

[@PBKB]

You such a comfortable voice! Great video, thanks.

[@bankruptpensioner]

Thanks for the compliment PBKB, must come from the time when I flew aeroplanes, trying calmly to convince everyone that all was ok 😆

[@GedandMichele]

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

[@bankruptpensioner]

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 😆

[@gordonyoung3668]

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

[@bankruptpensioner]

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 👍

[@bewareoftheoldman]

I asked Triumph, they told me 20-25mm for the Speed, 40-45mm for the Scrambler

[@ATiredRyan]

@@bewareoftheoldman Thank you for this. Couldn't find a solid answer, even in the manual. I did 30mm but I can adjust eventually.

[@tedsalmon2533]

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.

[@bankruptpensioner]

You are right Ted. My son has paddcok stands but thought I would tackle without like we used to do in the 80's 😆or certainly, I did 😆

[@MichaelWilliams-jc2ui]

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?

[@bankruptpensioner]

@@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.

[@ianhalliwell8604]

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.

[@bankruptpensioner]

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 👍

[@onecookieboy]

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.

[@larrywade9041]

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

[@bankruptpensioner]

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 👍

[@davidringgenberg8538]

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?

[@bankruptpensioner]

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 👍

[@malcolmtwigg7841]

You didn't show how you got the sprocket off I had to borrow a pully puller 🥵

[@bankruptpensioner]

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. 😆

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

[@bankruptpensioner]

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 👍

[@chrro466]

@@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. !!

[@bankruptpensioner]

@@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. 😆

Whats the benefit of changing the sprocket to 15 tooth? (I dont have the time to watch the video)

[@anthonybrown4874]

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.

[@bankruptpensioner]

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 👍

[@m2menuiserie540]

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.

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. 😮

[@bankruptpensioner]

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 😆

[@MichaelWilliams-jc2ui]

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.

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 👍

[@markonmotos]

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!

[@m2menuiserie540]

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.

Then you will have to have a go 😆

[@lexico69]

What are the gains from a 15 tooth sprocket?

[@bankruptpensioner]

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 👍
