Am legal @ long last! Only my CBT stands between me & nirvana! Two stroke heaven! 😇 ...

Stopped riding for about six months cause of old git health problems, only just renewed my CBT again!
Took me over a year to fit the new bearings and bushes into the rear suspension linkage! Didn’t realise how big of a faff it was going to be to get them pressed in straight and to the depth that’s needed for the seals! Done though. Nice and tight on the ass end! No more ‘snatchy chain’ feel when pulling away 🙂

Is HotShot still around? I need some info on wheel builders in Dorset. I can’t find the old post recommending a particular one. My back wheel is a bit up and down, as well as being a bit side to side…

Unless anyone has a decent straight rear wheel for sale?…
Ta!…

Trying to learn the habit to wash the salt off! I don’t have a hose pipe so I use a 3litre pump up garden spray bottle 😐

No bluddy way near perfect, but better than crusty salt~mud~spray!…its all I can do…

@HOTSHOT-III

Cheers bud! I forgot to fuxin fit that! I’ve actually got a good condition one to go on there. It’s amazing how so many hours work can look like so little progress! 🙂 …

For better, or for worst…

It’s done!…

@HOTSHOT-III

You were right, I had a closer look at the crank. The inside of the small end has ‘damage’ to it. I guess I’m gonna have to save up a couple hundy pennies for a crank before dreaming about new rims 🙂 Them’s the licks…

I’m seriously thinking about getting the tzr up and running. MoT it and use it, so as I can tear into the Dtr without time constraints. Get the frame dipped and painted and learn how to make a loom! It needs it. I want it to be a righteous little tear~about someday ☠️

Wow, this place is less active than my sex life! 😱 …

Ahem! I’m @39250 miles without being stranded at roadside! Was @14500’ish when I first got the basket case Considering all the problems I’ve had to learn through, it’s not bad…

Desperately want to build the new engine but have been busy doing diy for my sis’s gaff (Almost finished building the newish gates) Managed to squeeze in preparing the new cases for welding, removing bearings and studs. Apart from the clutch side barrel studs, which are the fuxing worst! Soon as the gates are hung I can start again on the motobicyclette 🙂

I only got this in May, but it’s MoT time tomorrow!

Eye exam in the afternoon so I can read a number plate @21 metres. CBT in a week with luck...

Am insured, so only tax needed as well...

It’s been 25 years since I was last legal on a bike, so I’m pretty excited...

Also remove the brass cup that the needle valve sits in and check the o-ring condition. Make sure the neoprene rubber tip of the needle is in good shape and secure to the needle ‘body’. Also make sure the spring loaded dowel pin is moving freely...

It’s best checked with the carb off and blowing down the fuel pipe while manually closing the needle valve like Calum suggested. If it closes tight but still leaks out the bottom outlet pipe check the bowl drainage screw/stop-pin is in good order and closing without leakage...

Good luck bud. You’ll get there 🙂 ...

@89dt125nick

It’s not an overflow, it’s an expansion tank. The radiator cap lets fluid out as it heats and expand, then back in as it cools…

@89dt125nick

The neutral wire is blue and you should connect it to the switch behind the gear change lever.

The side stand wire shouldn’t be earthed! On my bikes (1988-96) loom it is just not connected and everything runs fine.

The kill switch basically earths the wire to kill the engine. Your wiring isn’t right yet if it only sparks when earthed.

Can you remove your rotor and look at the stator plate? Or do you have a metal side cover with the stator in it, in stead of behind the rotor? Also can you please look for markings on the CDI unit?
Do you have a key ignition switch connected?

We’ll get it running yet bud!

@jonne123

No disrespect meant from the start! But I’m guessing that you’re about 17 and haven’t ridden a great deal of bikes?
Every 125 Has been restricted to about 12bhp since the late 80’s AFAIK. Any bike that is significantly above that has been de-restricted and/or tuned.
You can unrestricted early dtr’s by ‘pinning’ the power valve open. This will give you higher bhp but will basically make the throttle an on/off button with terrible response.
Later bikes I don’t know as much. You can unrestrict them and the variable power valve will still give you better low rev torque/response (I’m guessing that is what you mean by throttle response?)

Do some reading up on deristricting your year model bike, then do some riding. Stop worrying about numbers bud, enjoy a wicked little bike for what it is, before yearning for more...

True. You can get an excellent x~ring chain for £60 with JT sprockets! I haven’t had to adjust it since fitting. There really is no excuse for a chain so slack it skips the front sprocket!…

My first o-ring one was shit because it was missing a roller on the end link and I didn’t notice for ages (to my shame) it wore really quick

I forgot to say, I used to do a 70mile trip nearly every day, my bike had problems and it still never left me stranded. I’ve done 25,000 in the last 2 1/2 years. There reputation is based on 17 year olds who don’t know how to pour 2T, let alone do maintenance 🙂 It’s entirely undeserved. They are reliable workhorses…

@Stevie-Wonder

I learned to change gear on a dt50mx, 14 years old on the local rugby field. 2 nights later I was riding it round the town 😇 pitch black in the middle of winter. I ended up falling in love with 2/‘S, has more Vespas and lambrettas than I can remember. Margate is one of the places I’ve actually ridden to, never had any problems cause nearly all my scooters were chopped ☠️

I met an old boy with one leg through buying DTR bits on fleabay, he used to race 2/‘S he’s got a Dt LC with an rd200 twin engine in it! Also a beautiful unmolested kh350 (iirc) I’ve never seen one of before. As well as a mystery covered bike I haven’t asked about yet. He only lives a few miles away from me. There are definitely some really interesting old souls out there!...

@Stevie-Wonder

I know it might sound crazy considering I don’t have a crystal ball, but I’m not convinced you’ve ‘blown up’ your bike. It still turns over, yes? Not locked up? White smoke is classic head gasket blown and coolant burning.
I just replaced both my main seals without removing the engine! It’s easy enough bud. So is the head gasket and it costs about45 for genuine seals and 13 for a decent gasket...
Seriously bud, basic tools 👍 ...

At least strip the top end to check...

@R3L3_89

How do you roll cones?
Curves are made by sectioning bits together, see pic at bottom…

Can you Tig weld? If you’re going to do this you may as well use stainless steel…

Romeu Henrique stainless exhaust fitted with no issues whatsoever except I opened up the front mount hole to fit rubber bushing…

@Calum

I don’t think that it is. There’s no play on the lever, let alone sponginess, but I don’t think it’s getting the full pressure of the system at the pads. I can’t see any other reason…

47,125 miles today! That’s 34K since I’ve been riding 🙂…

It does sound familiar, doesn’t it?
In my case it sounds like the ‘part of my life’ that won’t let me remember how to be content, let alone happy. That it not deserved.
In my case I always put it down to being an acid casualty 🙂 and living in such an unharmonious, unbalanced, unaturual world. As long as I can remember I’ve always felt out of place…

It’s oddly comforting to know that I’m not alone! 👻

Cause there doesn’t seem to be any love in this fuxin world

@FloWolF

When I first started riding my Dt it took me 10 minutes just to do up my boots.
I had to climb on it while it was on the side stand. I had to stop riding from time to time cause my back was screaming at me.
I’ve had a trapped nerve in my back (& down my right leg) for the last 20 years!
I kept at it cause I’m an absolute stubborn fool 🃏
Riding actually got me limber again, it took a while and a lot of pain. It got me out the door as well, I was an agoraphobic, manic depressed nervous wreck. Getting on the bike and going out is one of the only things that gets me out of my pit in the morning (or afternoon!)
Having people around who can help you with the shitty gritty~cleaning parts of resurrecting a bike is a massive bonus!
Keep at it bud, it gets better when you actually beat the ‘gremlins’ and get it running righteously again! 🙂👍 …

We shall overcome! 😜 …

Got to love a survivor!…

I wish my lid was as resilient! 😜 …
