yep so i bought another one! and i do believe it to be a proper bargain! so the initial idea was to buy it for spares for my 84 cb twin but once i had a good look over it i decided against it.
the seller described the bike as 'sat at the bottom of the garden for over 10 years sold as seen' the tax disc expired may 1998 and the bike hasnt run since.
my first target was to hear her run! so battery off my other cb, and fuel tank.. and then a good carb cleaning!
a quick engine flush and a bit of oil and i hit the button.
a few turns of the motor and it fires Very Happy sweeeeet!
little puff of smoke from one pipe but both pipes getting hot at least! actually runs well, mileage of 11,000 so shouldnt be too bad eh?
the bike does have what i believe to be the usual superdream nasties like the rotten brake calliper pistons and shock linkage even with one perished carb rubber!
anyway take a look at the little gem!

how much did you pay for this? and how much would it cost to restore to a ridable state?

hi! i paid a hell of a lot really .. £50
now to get to a rideable state would cost a lot more! all depends how good of a job you do, i mean my first cb125 twin has just topped £800 so far and there is no tax or test and still not finished.
i would stay away from the cb 125 if your looking for something quick, cheap and useable. (unless you find a really good one!)
i just really like them but dont really need them for transport so i play with them. Laughing
a very pleasing bike to ride too when they actually ride. surprising for a 125.
if your looking for something cheap, useable and easy to get on with then i would say look for an old cg. i just sold one that i fixed up. cost a tiny £18 to fix (had a few parts laying around though)
but i sold it for over 100% profit! run very well and it did over 200 miles happily before i sold it.

THAT one, is missing its carburettors (unless Lozza has them tucked away some-where). On That particular model, they had CV carbs; they oft got wrote off for rough running, and a quote for £180 JUST to replace the diagphrams...
If you dont have the carbs, then you'd need to find a pair.... AND the rubber stubs to mount them.
For that bike you can still get, brand new, Lifan copies of the original CV carbs, from China, and they are about the price of a Diagphram & slide from honda, about £150. But you would have to add another £90 for the inlet rubbers to mount them up.
SO, before you even began, on THAT bike, you would have to bank something like £250 JUST to get the engine 'complete' and stand a chance of it running.
Second hand parts? Well, the linked PD24 carbs used on the earlier TD-C & TD-E models are not available new any more. Unlinked PD24 & PD26's are available, new or second hand for Chinese CG copies and pit bikes. But getting stubs to attach them to engine a hassle.
Those parts are almost completely unobtainable, and if you find a pair, in decent nick, and seller knows what he is holding? Well they can hold you to ransom on them; bikes actually get broken for little more than a decent pair of carb bodies and inlet rubbers!

SO, beyond that little 'niggle' what we got?
No body-work, and nice shot of the shock absorber, covered in pine needles to let me know thing has been sat in a hedge for umnpety years......

Hmmm.... shock might be serviceable, but I'd not bank on it. £80 for a new patern replacement, about £40 for serviceable second hand one.

BUT, of thats the state of the shock, almost garantee, that the suspension linkage will need attension. There are, if I recall correctly, five pins in the linkage, each with a roller and split bush to support them. They frequently sieze and on the TD-J which lacked grease nipples, almost bound to have never been lubed since the original warranty ran out, IF then! Rollers are aprox £7 each, and the bushes an annoying £8 each. So you are looking at over £150 to fully recondition the shock linkage.... THEN you can add another £50 or more to reconditioon the swing-arm spindle and bushes!
And THAT is presuming you can salvage a few old parts!

Forks? Almost sure will need forks seals and overhaul, if the chrome on teh stansioons is any good. If not forget it, and start searching e-bay for better bike to break and or better forks. Headrace bearings; could be cleaned up, but best replace them £25. Then we move on to missing body work. Best bet would be e-bay for a bike in boxes; £80..... then reckon on, perhaps £150 to paint it up, hoping that tank isn't pin-holed or inside rusty as feck.

So far we are looking at thick end of £600 or so, to cover not very much! Engine likely to need rebore & top end rebuild; add another £150; exhausts, add another £150; tyres? Might be OK, but budget another £100. Wheel bearings? Few pence in comparison. BRAKES are the annoying one; about £200 to fully recondition brakes on these things, thanks to very good twin piston floating caliper up front, and pistons costing £16 each.... so you are looking at £50 just to unsieze them! And they usually are! Float pins and rubber gaiters take front caliper overhaul to nearly £100, by comparison hose and master cylinder overhaul is pretty cheap.

Look at Snowie's Pup; yes, has a fair few 'pretties' in there; but, engine was never touched, and she was lucky it was a runner when we brought it in; Cost to get that one up to state its in, has topped two and a half grand.... I stopped couinting after that! Of which less than £500 is accounted for by pretty bits and accessories, and most of that 'non-essential' was taken up with the LED lights to leave power for the heated grips and alarm and stuff; but bike would still NEED lamp bulbs even if you used 'cheap' tungsten bulbs! And grips, even if you used ordinary rubber ones, etc.

Typically, 'viable' renovation bases of these bikes are going for around £350, which is approximately where the Corporal I did started. To 'smart up' with a lick of point, need only cost £150 or so, but they wont look great, and they'll still need some mechanical work to get through an MOT, and realistically, to take a fairly viable project base to a reasonable enough standard to ride, and be every day useable, takes in the order of £7-800, depending on standard you work to. How 'useable' you'd get for that money, would depend on whether you prioratised pretty or oily, and how 'lucky' you were with carbs and rubbers, exhaust and ignition, cylinder compression & crank bearings, and avoided completely fucked shock links etc.

These bikes are a tad too sophisticated to make cheap and easy restorations, and not quite sought after enough to have a final value, enough to justify chucking the money they often need to get them half decent.

Lozza and I do them for 'fun'; its a hobby. We both have bikes that offer much more 'bang' for your 'buck', whether time effort or money; but these little bikes have charm; they were under rated in thier day, and these days even more so; BUT they are little corkers; designed in the days when Honda were seeking to prove thier supremacy and that of the four stroke engine, to compete head to head, on performance and specification.

They achieved that;

They may look like a boring CG coimmuter, but they are far from it; twin cylinder, twin carb engine, was WAY ahead of its time, and in full power guise chucked out 17bhp, as much as any of the two stroke rivals; but did it with mid-range, not just 'peak' power you had to rev the nuts of the motor to get at, this thing out power to the road from almost ticke over to its audaciouse for an air cooled two valve per cylinder engine, 12,000rpm red line.

Meanwhile, it had better brakes and suspension than either Kawasaki or Yamaha 'Sports' 125's and STILL better than modern CBR125.... and despite concervative styling, lack of fairings or belly-pan or anythng, the damn things 'handle'!

Point to point, they are a VERY fast learner-legal!

There's a lad with an R125 round here, spotted me training Snowie up, so did a few laps, buzzing us; few days later, he spotted me puilling out of the housing estate, heading out of town, so changed his indicators, where he was going to pull 'in' where I was pulling out, and sought to 'race' me... you know, chase the commuter, let him see a 'real' bike in action on the twisties and see what he's missing......

He was doing 40, as I pulled out, and out of town down the NSL road, he never even came CLOSE....

Off some lights, lad on two stroke Derbi got a shock too!

These are CHEEKY little bikes!

But, they are great learner bikes; that twin pot motor is very very smooth for a 125, and it will 'trickle' through CBT and training cones beutifully, with nice easy responsive power delivery and hardly any drive line snatch, if properly set up.

Upright riding position gives control, and visability, as well as comfort; again, round the cones, its very easily managed....

I tool Smiler round the car-park on the Corproal, two up, and at 15mph was decking the pegs to show him just how stable and nimble it was!

They are a very very good 125; they have all the practicality of a mundane commuter, with even more added 'rideability' by way of forgiving engine, yet, the performance of the sports bikes, and an eagerness few of them provide, especially in learner legal power limits!

And they are an under-valued, under dog, which makes them lovable', gives them charecter and charm, few 125's have!

But that TD-J?

As pictures; it practically little more than an engine donor! And even THEN an incomplete engine donor, without carbs!

yep i have the carbs that came with it but they are kind of fooked/not worth the hassle, back to the jialing leftovers. well, i have dug out some lovely condition carbs and inlet rubbers Very Happy bonus! rear shock absorber as you say is scrap. i will have to save the linkage though.
forks are pitted so will have to think on that.
i did get some panels for it but what i am missing i have as spares left over from my other cb so will try and use them.

early today i have been stripping the frame... in the kitchen! the rain put an end to work outside for the day.

lol yea im really not looking forward to it but plan to tackle it next after the frame has been cleaned up. your right about the handling on these bikes they are awesome! and running well can outperform a 4k yamaha r125 then! will mention that to my young brother and maybe then he would use my 84 cb next year when he is 17. if weather was good i would insure it myself being that car insurance for a 20yr old is so expensive.

Probably ought to have a BIT of qualification; Well fettled CB125 TD-C, rebuilt engine & 'control' carbs; Ie fully reconditioned with all the bits that are now NLA, all new ignition components; properly set up, with lots of plug chops to get the mixture spot on, balenced on guages etc.
Forks reconditioned; suspension overhauled, steering overhauled, you know, done 'well'......
Ridden by a bloke with trophies on his mantle-piece, who'se been riding since he was knee high to a grass-hopper, dirt, road, track, etc...
vs...
Thrashed from the box, R125... with teenage tit on top.....

Nope he didn't come 'close'... but I don't know whether the bike can take ALL the credit, nor even the rider!

Squid-Kid could possibly have been on an R1..... and not knowing how to ride the thing, still not stayed with me!

But; un-fettered by emissions friendly injection, or tuned for harsh noise regulations, and ecconomy, the little Super-Dream engine, down possibly 2bhp on 'peak' power, makes up for it with smooth, eager 'drive' giving all it can give, or as much as you ask for, as much as it can.

Yes... I AM 'missing' the Corporal!

up early this morning cleaning the kitchen! took many hours! will NOT be stripping paint/rust from another bike in the kitchen any time soon. Laughing
so when i did get around to the bike ( what there is of it) i finished cleaning the rust from the frame outside Thumbs Up
gave it a wipe and painted it.
not a bad start i thought but things changed when i got to the swingarm and linkage!

this is the point of the rebuild i like, now i just clean,buy,service and renew everything i can or want to and start to build it up! i should mention this is also the point where i spend the money....
things i know i need so far
rear shock (wemoto ask for over 200 for a hagon!) i might take one off ebay for 80.
fork seals and dust seals (maybe stanchions)
brake calliper pistons and seals
a decent petrol tank if i can
headlight
front tyre (pirelli mt65 looks great on the back, front dunlop has cracks all over)
chain and sprocket kit
a good seat or cover
looks like air filters too
more than likely a lot more!

Smiler paid me 'sensible' money for the Corporal; Didn't cover the full cost of build, by a long stretch; especially if you take out the price of the two bikes broken for most of the second hand bits used; but he only bought a bike with ONE engine... cant expect him to pay for my mistakes or misfortune, when I had to pay for two barrel kits because the first one was mashed up by the cam-chain snapping! And he only has one rear suspension, and one set of forks etc!

But he got a bike, in decent nick, with the important stuff all pretty well sorted, that looked good, and goes good; for what would have got him a fairly tired City-Fly or YBR for, and appreciates what he's 'got' with the Corporal; so I dont think either of us feel too agreived at the 'deal'....

I just have 'pangs' now and again when I look outside and its not there, or I think 'I'll just nip to' and go to reach for my crash hat... and 'remember'!

But, ultimately; I bought that bike to get me 'doing stuff'; occupational theropy! And Yeah...

Original Idea a year ago, had been I was going to do the Yamaha, Snowie was going to do 'a' Super-Dream'. But we got that dodo of a bike with hacked frame; so went shopping and four came up together on evil-bay. Red one and silver one, so thought to get both, and do one each.

Meanwhile, 'The Black-One' was not getting much attension and looked like a 'quick fix' to give Snowie a rider, while she did her 'project- bike'...


But she was more enthusiastic about doing the Pup and over optimistic about how quick it would be finished, so it got back burnered.

Then Corporal turned up, Taxed & Tested, with dead engine; and looked like a promicing way to make some use of the few decent bits from the 'heap' bike with butchered frame, namely its running engine.... worked too, and If I HAD had any sense, after dropping that motor in, and starting it up, would have chculed it straight back on e-bay, taxed, testing and working, and MAYBE got back 80% of what I had spent on the two bikes, and some-one ELSE could have tackled the paint work, and grumbled when that engine didn't work so great!

But didn't... turned into full ground up job Blogged! And I THINK I made a nice job of it! I'm out of pocket on it, BUT, I could have wasted as much or more making ship in a bottle kits or trying to make wonky furnature, that would have done nothing for any-one but given relatives clutter to be embarrassed about when its not in a pride of place when I visited!

And I got a bit of use out of it; we calculated I did 500 miles on it in six months......

So, would have been an expensive garden ornament for me to have lying around rusting back to the state it started in! And I have plenty of rusty Garden Orniments as it is!

And what I got for it, has given me the funds to get moving on the Yam 'Enduro'.... which IS a bike I DO want to keep....

OUGHT to be clearing the Decks a bit, and the back-burnered 'Black-One' WAS 'fixed' in as much as I rebuilt the engine, which was most of what was wrong with it, and Snowie then demolished the rest so I could scrub it up and grease suspension and 'stuff' to make nice; becouse it WAS a pretty nice bike when we got it... just didn't run!

But SHE STOLE THE ENGINE... and is holding it to ransom against her Suped-up-Super-Dream 200 we lack a cam shaft and carbs for......

So I probably ought to be looking at 'The Deal Twins' the two silver bikes, that were supposed to be my 'original' project before getting side tracked! One a viable resto, other a 'donor'.... except, after a bit of prodding and poking, BOTH look viable, so intent is to do 'scruffy' the one originally intended as a 'Project' as a 'seller' then try and use all the bits I have left over to do 'Five-alive' as a keeper..... dont really have THATR much use for a 125 Super-Dream, Yam & the 750 are tough enough toi justify keeping in 'commission' for amount of use they are likely to get... but would like to keep one as a suvineer of it all, and I have kids aproaching teen-age, and my Daughter has already been trying all my bikes for size! But by the time she's 17, 3rd Directive will be in effect, and she will only be able to have a 125 until she's 19... so having a 'little dream' stashed away? Wouldn't let her loose on the Yam.... even though it does say 125 on the V5!

But tackling THAT, becouse I want to! So far I have bought a can of engine paint, wasted £3.99 on some HORRIBLE banana Yellow Plasticote, that just WONT look right on the bike, a monkey bike 'regulator' to try a 12v conversion with; and e-bay bargain hunting, TODAY, giving myself near apoplexy trying for last moment 'snipe' bid; I won a pair of New Old Stock handlebar grips and a pair of lever blades! Total SO far running at £275.41p...including price of the bike! There's about £500 worth of 'bits' on the wish list at the moment, and I haven't had plastic coating priced up yet... and I am clocking bits like the shock absorber pin that didn't come out whole, and all the rusty nuts and bolts I'm taking out and am unlikely to re-use....so I think I might have to cull some of the more ambitiouse ideas, like the £70 PIR Headlamp conversion. Laughing Not likely to spend much time riding in the dark ANYWAY!

Probably NOT going to leave myself any money to sort Snowies Suped Up engine, so I can have mine back to sort the black bike... but face that as it comes! at least I'll have something to fill the space left by 'The Corporal'!

And I DO actually have a fair bit of 'stuff' in the 'ready spares' box to start tackling one of the silver bikes; like fork seals, steering bearings, fork gaiters, where I have clicked Qty 2 whenever I have needed sopmething for Snowie's bike or the Corporal, in anticipation!

But Yes.... post tear down euphorioa of how 'nice' its going to be, and enthusiasm to see it 'done' does take something of a HIT when you start compiling the early shopping list!
