    Welcome Kev,

    Hope you find things of interest within the webpages. Your MX is a little bit younger than my 78 model, but having restored mine also they are very easy to work on. I've got lots of photos of the engine/gearbox strip down which may be of help to you. Having said that, the best advice I can give is to take lots of photos with your phone/camera, i took hundreds as I worked on it, which were also invaluable on putting it back together months later. Its not like the old days of processed film, it doesn't take up any room on your SD card! and you can easily delete what you don't need.

    The forum is very quiet these days, hardly anyone seems to post, me included . However, i do glance at the site most days to see whats going on. If you have any questions ask away, and if i can help out i will.

    Start a new topic in the Workshop section if you have any questions.

     

    All the best, and welcome once again.

     

     

    Cam chain tensioner.

    Well done Slice, leaving a cloth inside the engine reminds me of when surgeons find they are missing a swab at the end of the operation! although we had procedures in place that ALL swabs are counted before final closure!....but you still hear stories of swabs and instruments turning up post op!!

    Anyway, good job you've got her all back together and are the proud owner of a nice set of shiny sockets!

    I remember doing the cam chain and tensioner on my 400/4, I even did a video on you tube as I shared my experience to help others.

    Well done Slice, have a pat on the back from me.

    hi there, you don't say where you are in the world.

    There is Musket Mufflers in New Zealand who are known to stock a lot of Yamaha exhausts, and can apparently custom make any system. Might be worth looking them up. They had an off the shelf front pipe repair section I bought from them for my DT175MX

    Female connector/crimps

    Hi again,

    just re-read your post.

    Are you trying to source the  actual connector on the loom? (which plugs into your relay)

    OR

    Are you trying to find an alternative relay with an identical pin out to replace your R1 version.

     

    You may have to contact Yamaha.

    Hi Gingerchili,

    Are you referring to the name of the connection? as in:-  "D connector" where "D" is the physical shape, "JST connector." (japanese Solderless Terminals). DIN connector (Deutsches Institut für Normung) connector. The List goes on and on....

    The connectors listed above have one thing in common....they, at the time, have been 'standardised' .As in manufacturers making something to a standard across the industry so that their parts become compatible.

    However, Relays and the like have numerous pin outs, depending on the internal circuits of the relay etc, 10 pin , 12 pin, 18 pin etc, They subesquently have the pins grouped together in various box shaped sections, they may well have a name used by the manufacturer, but its not a term commonly used for its sales potential. So they tend to be referred to by 'gender' ,from the plug or socket, such as a 12 pin male or 16 pin female etc. (Molex was/is a brand name of common vehicle connector)

    Quite a few years ago I dabbled with electronics and made a few bits and pieces, but I never came across a common name for relay and other black box components in their detailed catalogues, other than by brand name /pin out and gender.

    Hope that's of some help.

    The vast majority of speedometers are sealed for life, as in, constructed in a manner to prevent the mileage being altered that might not be true!

    Having said that..everything that is 'constructed' can be 'destructed' or reverse engineered!

    The question is, whilst you can get it apart, can you put it back together?

    That all depends on your ability and 'whats acceptable'. to you.

    I've taken apart quite a few...for cleaning purposes!....I've done both my Honda 400/4 and DT175 speedos, and I've put them back together. ...but...you can tell I have! They won't win concours, because you can see what I've done, which is fine and it's acceptable to me, both are watertight amd don't steam up. The  Honda had a chrome ring around it which was compressed onto the two 'halves' of the speedo. I knew I could not re-compress the ring back on, and make it look like its never been disturbed, so I cut the ring and silver soldered a very tiny nut and bolt back on it and simple tightened them up. I hid the join the best I could between the speedo and rev counter.  If I remember correctly, the DT had to be cut in half in a place that was concealed by the stainless steel lower cover, and I used a soldering iron to 'melt' the plastic back together to re join the two halves. You can't see the join, unless you take the metal cover off.

    So answering your question: "Does anyone know if you can strip the speedometer gauge on a dt50?"

    Then I'd say yes you can... but It's unlikely that it's been designed in a way that you can dismantle it easily!

    or ....buy a another one!😁

    Good luck , hope that is some sort of help. Let us know how you get on.

    Yamaha XS500B Smokes on right cylinder

    in The Bar

    Posted

    Hi there William, welcome to the group, can you just clarify what is smoking.

    Are you referring to smoke coming out AROUND the Right cylinder itself?, and as Snake suggests a good smoothering of soapy water whilst the engine is running will help locate any location of a leak. Base gaskets are common source of poor running and smoke.

    OR

    ..are you referring to the Right cylinder as being the source, as its smoking OUT of the exhaust pipe which serves that cylinder?

    In which case what colour is the smoke,? white, black?, etc. because then it's either oil from the sump, or unburnt fuel gases getting  past the valves.

    DT175 MX Petrol cap tubing

    in Classics

    Posted · Edited by NE0

    Hi there Christian, being the owner of a 78 DT175MX i can confirm that Finnerz is correct, it is just the breather tube for the petrol cap (as mentioned in your title).

    I poke my breather tube down between the front yoke of the steering, it stays there quiet happily throughout the ride. Never had a problem with mine, although after 40 years the rubber can perish and, after several decades, they can end up a lot shorter!, I think I replaced mine with a length of nitrle rubber a few years ago.

    tank

    Another purpose, other than a breather, is if the bike is laid down (in the mud on a trial...as it was designed!!) then fuel doesn't pour all over the painted tank.

     

    Hope that helps, and welcome to the group.

    Annoying

    Hi there, as Snake above has said, he'd be surprised if it didn't offer the ability to alter the height, so i took a look at some promotional photos on google.

    As it's a brand new bike, there's some interesting photos of the bike on various websites. https://www.appleyardmotorcycles.co.uk/used-motorcycle/yamaha-yzf-r125-world-gp-60th-anniversary-2022-32629

    https://www.motogb.co.uk/used-bikes/yamaha-yzf-r125-world-gp-60th-anniversary-2022-32128

    in the gallery sections I notice the top of the pedal is just below the support bracket seen behind it. The first question is, does yours match the promotional photos? or is yours set higher? if it is, then it should be adjusted to match. The place you bought it from should be able to reposition it.

    In this utube video, pause it at 2mins 53 for a nice view of it.

    https://www.youtube.com/watch?v=OaDkByqGPiE

    Secondly, and no disrepect implied here, are you riding it in the designed foot position? I notice the riders in the photos have their mid foot on the peg and their heel over the exhaust, are you for example riding it with your foot too far forward? or are you too tall for the bike?

    I say that last bit for a reason, you see my 400/4 is designed for someone shorter than me, I'm six foot, some say I look too big on it but it's a lovely bike and I don't care if I'm technically too tall for it! but with size 12 feet it does mean I had to alter my foot position to ride it, in the end I too had to alter the angle of the brake pedal to ride it comfortably.

    1981 Yamaha XS400 Cafe build, Drain Plug Stripped and Other Issues

    in The Bar

    Hi there and welcome.

    If your're moving the handlebars and it's causing a change in something that's being run by electricity, then for sure you've got a wiring issue!!

    The wiring loom runs down past the steering head, and has all the wires from the handlebar switches within it. However, it's also designed with a bit of slack to help it move with the handlebar. Unfortunately, your bike is already over 40 years old (1981) and the wiring loom will be breaking down. Nothing lasts forever and plastics and rubber are the first things to go brittle and become cracked as the years become decades. The loom will no longer be as flexible and will now be quite stiff.

    After 40 years of movement you can expect exposed wiring and broken wires from all that motion within the covering. A repair maybe possible by stripping away the covering and finding the fault but putting it back together and expecting it to last is another matter.  The likelyhood of this happening to another wire in the same area will be very high. The most sensible solution would be to replace the aged loom for a new one, but that requires stripping the bike down. Regretfully the loom is often the first thing that gets attached to a bare frame in manufacturing and everything else is bolted on around it!

    How long do wiring looms last for? a difficult question as some will say they know of 100 year old vehicles still working, however, the manufacturers never designed them to last or even expected them to last! The fact you're having issues with yours suggest it's starting to reach the end of it's serviceable life.

    You can probably get it repaired, but you may find a previous repair.! either way it won't fix itself.

    kind regards NE0

     

    How to verify age of NZ DT125 1979 in UK for registration

    in General

    Posted

    Hi Ben, Welcome to the group and to this side of the Planet!

    To get free MOT and free road tax you have to first have your V5C registration documents issued by DVLA to state 'HISTORIC' in the taxation class. I can't help you how to obtain the V5C in the first place though! Someone else will hopefully explain how you go about importing a bike into the UK and getting your V5C.

    Here's my actual account of how I changed my V5C to HISTORIC.

    as mentioned in the text , it's not an automatic process just because its over 40 years old. From DVLA's point of view they are quite happy for you to pay Road Tax, they won't tell you that you can get it for free, nor will they tell you the Bike is elgible.

    Incidently, whilst the road tax is 'free', the MOT side of it is; YOU are declaring that it is SAFE to be on the road, and are taking full responsibility for it meeting the road safety standard for an Historic bike. Although there is nothing stopping you putting your bike through for an MOT and paying for it.

     

    You also mention you'd like to do a 12v conversion, well I too did this to my DT175MX over 10 years ago and here's the indepth account on how I went about it, have a read if you haven't already. Usual disclaimer applies. This was my bike, no idea if it would work on yours!

    https://yamahaclub.com/forums/topic/25945-dt-175-mx-12volt-conversion/

    well, there's a start for you, once again welcome to the group, whilst your here, why not pop over to the new members section and do a brief introduction,which always goes down well.

     

    All the best

    1978 dt250mx rear brake light switch

    in Dual Sport, Offroad Bikes

    Posted · Edited by NE0

    and this photo shows the little tag poking up just behind the brake pedal

    https://www.thebikespecialists.com/vehicle/yamaha-dt250-mx-classic-iconic-trail-bike-excellent-condition-in-sheffield-43b7fe63-9b9e-4049-9742-c35103cd06e9

    one of the photos shows a close up of the brake side....you can just about make it out.

    This gives an indication that the tag has to be uppermost.

     

     

     

    Yes, there looks like a small spring attached to that arm, do you have that?

    hi Graham

     

    Not sure if this helps but this is my 1978 DT175MX rear brake light set up.

    brakespring2

     and the other end of the spring goes on the top part of the brake pedal

    brakespring1

     

    the switch part points down towards the pedal, and is held on by the plastic nut. It fits in a welded ring on the frame.

    The long spring attaches to the 'pull out' plunger and the other end attaches to a hole in the top of the brake pedal.

    When you depress the rear brake , it pulls the plunger out and this makes the internal switch close and the rear light goes on.

    I appreciate yours may be different but it may be helpful.

    Merry Christmas 2021

    Hi folks,

    Just thought I'd take the time to wish you ALL a Merry Christmas and hope you all have a better 2022.

    The forum has got a lot quieter since I first joined ten years ago, nonetheless I still visit every few days to read whats going on with you all.

    I still enjoy the banter, even if the bikes don't do many miles at all these days.

    Have a great time and enjoy your family time.
