    Rear sprockets are beyond my ability to find for sale, other than standard 57 tooth ones...

    What the fuel is going on with the site? Most buttons don’t work, it’s totally FUBAR @ the moment 😐 ...

      All the date and time stamps have disappeared! Nearly all the buttons are inaccurately inactive 🤪 Or is this just happening @ my end?...

        @SpookDog Probably not, I upgrade the software yesterday.

        Try clearing your browsers cache

            It’s still not working. I’ve deleted my cache, turned off the phone and the only way I can post is the bar at the top and I have to turn the phone sideways to do that! If I press the reply at the bottom of someone’ else’s post it returns me to the top of the thread! Weird!...

              @SpookDog What browser are you using?

              On Firefox I used "Forget About This Site".

                Oh! I only just read the ‘I upgraded the software yesterday ‘ bit. Just when my problem started! Is it perhaps not iPhone friendly?...

                    @SpookDog No it's probably because your browser has cached something and the page is error.

                    It's just using Bootstrap so it's unlikely to not be Safari compatible.

                      I’ve cleared my cache, and it’s only started since the software update. I might be the only one using an iPhone. So it only bothers me ☹️ ...

                        I use IPad and IPhone no issues so far…. You have upgraded to iOS 16 haven’t you ? That’s the latest software.

                            @SpookDog It'll be something to do with your phone unfortunately. There isn't anything I can do my end to fix that.

                            If you go to the Apple App Store and download a different browser you'll see that it'll appear as normal.

                            It's working fine my end after I patched the software, but when I used my laptop the website was totally broken for me. Clearing my cookies/cache fixed this issue for me.

                              @SpookDog I've had similar problems in the past. I just signed out of this forum then signed in again.

                                Tried downloading browsers but it needs iOS 13 or higher. My old iPhone 7 is only supported to 12.5.
                                None of the funcion buttons are working. I can’t see new updated posts or anything.
                                I’ll try and keep up through other means, but until I get a new phone, Adios! 🐾🐾🐾

                                  @SpookDog hhmm 🤔

                                  I am sure its just a browser cache thing, but I can't not patch the forum software, otherwise its vulnerable to critical vulnerability exploits, ransomeware and denial of service attacks.

                                  I mean you only have to look at the 'User Sign Ups' to see the bots that hit this website on a daily basis.

                                    iOS 12.5 isn’t supported anymore, we live in the age of built in redundancy 😑
                                    Oh well! 🙂

                                    My front sprocket has been wearing unevenly on the inner side. I’m wondering if there are different front sprocket spacer sizes? If the lock/tab washer thickness could affect, or if I’m just missing a normal washer? I’ve never seen a sprocket wear away on one edge/side before. I can’t work out what is causing the discrepancy in the front to rear alignment to cause the wear. Any insights, anyone?…

                                      Am I right in thinking that there are only 3 wheel spacers for the entire Dtr range? Two rear and one front? I’m hoping that I don’t have the wrong width spacer on my bike that is causing the offset in my sprocket alignment?…
                                      I’d rather fix the problem than treat the symptom by fitting a spacer-washer to the front sprocket…

                                        @SpookDog The front wheel spacer is very different to the rear wheel spacers so you'd know if you'd got that wrong, in fact it's a much smaller ID than the rears IIRC so that's ruled out.

                                        The DT200R drive side rear wheel spacer is a lot shallower than the 125 (because the 3ET alloy swingarm is a lot fatter at the ends) but you'd notice if you had a DT200 spacer and a 125 steel swingarm, I mean you'd have to physically pinch the swingarm ends together to tighten the rear spindle. Which would probably result in bigger problems than slightly uneven sprocket wear.

                                        Depending upon how your snailcam chain adjusters are oriented and which side your rear spindle nut is on, it's possible to inadvertently adjust one side wrongly when tightening the nut but if you've owned and ridden the bike for a year or two you're unlikely to get this wrong. I like to have the spindle nut on the brake side and the snailcams oriented so the brake side one has to rotate clockwise to tighten the chain; this minimises the possibility of the cam slipping. Also snugging them against the anchor pins on the swingarm by wedging a rag between the chain and rear sprocket whilst tightening the spindle nut helps.

                                        Assuming your swingarm bearings have no play (worth checking) my money is on the swingarm side clearance adjustment having been done wrong by a previous owner. It's a lot less complicated than Haynes makes it look (how unusual lol); you're basically trying to get the swingarm to move freely with 0.4-0.7mm of side-to-side play with the swingarm pivot nut done up tight (the arm should fall under its own weight with the nut tightened and without the rear wheel/linkage attached). Crucially, if you need to add shims to take up excess play, Yamaha insist you only add them to the right-hand (i.e brake) side; the one 0.8mm shim on the drive side is what retains front/rear sprocket alignment. Here are some pics of the procedure in the Yamaha manual along with my calcs from the last time I reinstalled a DTR swingarm written in my childlike scrawl.

                                        One other thing, if you get an All Balls 28-1212 or similar bearing kit (the WRP one is exactly the same) they come with 1mm shims; Yamaha shims are either 0.8mm or 0.3mm so you might need to order some if you get the arm out and find you don't have enough to get the side clearance right. And 90Nm is ridiculously, thread-rippingly tight for the swingarm spindle nut IMO; Yamaha do this a lot on the DTR, I guess so they don't get sued for major components falling off when young lads are out riding. I've always done up that nut up to 55Nm and it's never moved.

                                        No-one ever does swingarm side clearance on the DTR; even with some of the "DTR specialist restorers" you can tell by their social media pics they don't bother with this step but potentially, if it's far enough out it could produce uneven front sprocket wear over time. Even if it's not the culprit, checking it will it give great peace of mind!

                                          Am I right in thinking that there are only 3 wheel spacers for the entire Dtr range? Two rear and one front? I’m hoping that I don’t have the wrong width spacer on my bike that is causing the offset in my sprocket alignment?…
                                          I’d rather fix the problem than treat the symptom by fitting a spacer-washer to the front sprocket…

                                          @SpookDog Also just had a look on Fowlers Parts, the 3RM DT125R and 3ET DT200R output shafts, sprocket lock washer and spacer behind the front sprocket are all the same part number. Only the sprocket nut is different (I guess thinner to accomodate the 200's 520 front sprocket) so I can't see that affecting sprocket alignment (unless someone has tried to bodge it with a DT200R sprocket nut and extra washer between the front sprocket and spacer, but this would be very unlikely).

                                          Only other thing I can think of would be if the bearing behind the front sprocket is on the way out allowing the output shaft to move around. This does happen eventually when people adjust chains too tight on bikes with long-travel suspension but would be very noisy if it were that far gone and you'd be noticing oil leaks and gear selection problems and all kinds of stuff...
