    I’ve always froze my bearings heated up the hub greased everything up then gave a bit of gentle persuasion, never had any problems the couple of times I’ve done it but that’s a pretty handy trick

    I've only used Zeeltronics on all my bikes and they've been great. I'll be picking another one up for my new project in the years to come.

    I've heard good things about the Ignitech system @Darty swears by them.

    @SpookDog I've had good results with car shampoo in the past, it has the same lubricating qualities as Fairy Liquid but without all the nasty elements which rot the rims from the inside.

    I used to have this problem fairly often with Avon TrailRiders in the recommended sizes on DTR rims; excellent tyres but it was always difficult to get them to pop the bead and sometimes I had to deflate the tyre completely, remove it and refit 90 degrees around the rim. This is even after blowing them up to 50psi with the valve core removed using a compressor. I've had to leave them at this pressure for 30 minutes or so in the past as well, and resort to other tricks like hammering the sidewall kind of downwards with a rubber mallet at the affected spot (watch the rim!). It was only ever a problem with this particular make and model of tyre, they were ace on the road but Avons have always been a bit strange.

    Most bike shops fit tyres using the 50psi-no-valve-core-compressor method. This might not be what you want to hear but if your rim responds to this treatment by exploding then it was a pretty safe bet it was sufficiently corroded to be unsafe to use. Slightly off topic but there's a well-known story called "The Imprint of Death" they tell kids at tech colleges about a tyre fitter who was fitting a truck tyre and didn't bother using the circus animal-sized cage they put them in to pop the bead; it went bang and half of him ended up stuck to the ceiling. A bike tyre won't do that but still has a lot of energy stored in it, enough to do someone serious harm if they're stood right next to it. I think if I was worried whether a crusty rim of mine could handle 50psi, I'd be on the lookout for a new wheel to be honest.

    @SpookDog On reflection maybe my "dead money" comment earlier was a bit dismissive; I was a bit pissed when I wrote it as I'd had a MTB problem in the rain the previous evening and was looking at the wrong end of spending the day fixing it. So apologies if I've annoyed/upset anyone.

    In my opinion is very stupid to stop termic vehicles and force people to reply them with electric vehicles because they are not the main cause of pollution. The governments worry about stopping an 70's year vespa, which can go for 30 kilometers with a litre. But nobody talks about the trucks that travel all day and consume more than every other vehicles. Or the ships and plane, which have no anti pollution law to comply with.
    And even if we stopped all this vehicles, the pollution will not disappear, because just one country like China or India pollutes as much as Europe and North America together. We should stop to trade with the countries who are destroying the world. The thing I hate the most is that the people who protest against termic vehicles are the ones who daily buy stuff on shein, temu, aliexpress, thinking that there will be no consequence on the environment.
    Unluckily, who make the laws don't want to understand this.
    I hope people will become more aware of the real problem, and I hope the eco-madness stops soon.

    They are fuel overflow hoses. Attach a hose like shown on the other side and feed it underneath the bike away from any hot areas.

    They're designed to flow gas away from the bike and hot areas should the bike fall over and the tap not be shut off.

    Now that the engine is done, I suppose it's best I return back to the frame. I've contacted another local powdercoaters who are able to do the work for me and it'll be dropped off tomorrow. Fingers crossed they do a pucker job this time.

    This is it as of yesterday, it hasn't been touched since I got it back from the coaters.

    My garage is also very warm as it houses the gas boiler which means it's toasty in there all year round.

    Meanwhile I saw this cheeky swinging arm over in Italy for a measily £50...

    Now despite already buying and refurbishing an aluminium swinging arm, at no small expense I might add, I do prefer the styling of this arm. I wanted this arm originally, as this is what you'll find on the MX, however the one on the MX uses a special kind of dog bone which I could not source for love nor money. However this one came fitted with the same dog bones that you'd find on the RX/SX/ETX and claims it came off an RX. So I snagged it.

    Dimensions wise it all checks out the same as the one I originally bought, so there should be no issues with spacers, clearances or alignment.

    It's a lovely bit of kit and a few minutes on a basic polisher shows how good it can come out.

    I'll be sending it away for vapor blasting and new bearings have been ordered.

    Question is? To polish or not to polish?

    I'm looking forward to getting this bike reassembled and back on the road.

    @eric74 Fair play for getting on and replacing the tacho drive O-ring. Looking at your pics I'd say the oil is definitely coming from where the cable joins the tacho drive so I'd order the oil seal for this (item 7):

    https://www.fowlersparts.co.uk/parts/4083282/dt125r-3py3-1991-999-a/tachometer-gear

    Looking at the 4th image you posted up, the plastic breather stub should be right behind the tacho drive about where the old O-ring you mentioned is so it looks like your breather is missing (items 14 and 15):

    https://www.fowlersparts.co.uk/parts/4083277/dt125r-3py3-1991-999-a/crankcase

    Not sure whether oil would be visibly leaking out of here if it simply wasn't fitted (you never see any oil in the clear tube IIRC) so it may be that someone had the bright idea of plugging the hole with silicone sealant or something similar. Have a poke around here but be careful, if that's what's been done it would be too easy to end up with it disappearing into the crankcase, but if you're patient with the needle nose pliers/tweezers etc. you can remove a wodge of sealant like that from the outside.

    A tyre/rim chart I have says up to 80/90-21 is ok,90/90-21 is what I will put when I change tyres.
    Don't remember where but someone fitted that size to 1.60-21 rim and had no problem.

    But what you're talking about is replacing the whole ignition system, flywheel, pick up, stator and CDI because you don't want to have your RE/X crank rebuilt.

    Hi,
    I followed the advice of Spookdog and Stevie Wonder and ordered one in Portugal from Romeu..
    is now on its way and can arrive at any moment
    in terms of price this was also the best option.
    I'm very curious about the sound and performance.

    It's doable. I've taken parts from 3 Mikuni 28s.One from my DT,one of a TDR250,one that has oil feed tube don't know what bike and made my current carb.
    The one with broken is off,the bent tube is overflow if memory serves.
    Chokes are the same.
