Both cylinder have been Re-sleeved badly ! OMFG! I went and looked after you said that... Geeez... US!  I didnt bother getting the pic of the numbers, they were quite neat really but totally not original. Sigh... ebay is the dumping ground for these engines at the very bottom of the barrel, even at £1650! |

In fairness if someone that doesn’t know much about these bikes we’re to measure the inlet side it would measure 28mm. Jon |

The add says ‘standard porting!’ and is therefore not as described as per ebay rules.
The ports cut into the liner are so bad it’s obvious they’ve been done by someone that shouldn’t really be attempting such work.

Trouble now is, someone, unless clued up will buy that, and then realise there are major issues with that motor, possibly even join this forum asking for advise and opinions. EBay really is a shit hole for buying stuff, unless you are very familiar with the item you're interested in, then its an expensive way to learn a lesson.

The port above the main inlet port (is it the 7th port?) looks really small. It also looks like no attempt has been made to put a chamfer on any of the ports. Worth something to someone but not £1650 to me  Not even £650. Maybe at £150 if it was up our street. |

WOW you lot - the guys selling this as honestly as he possibly can, he not flogging a built up Banshee engine with Chinese components that are sold on forums by mods etc everywhere with no mention of them being cheap Chinese crap, he’s even stripped the engine down so buyers can look at everything, not left it together to fool someone. I was very tempted to bid on a Banshee Alcohol motor that was recently on EBay at around 3k recently, the guy wouldn’t even take the head off to show me the pistons, he reused to do so ? That’s more dodgy than a listing like this, you can see almost everything you are buying and not everyone is that Amal on what’s what, There’s lots of stuff like this lot still being unearthed from garages and sheds, in the early 80s these were the hooligans choice of bike of the day, not show bikes, a mate of mine hit a tree on one and didn’t survive, they were brutal, regards this lot, Ive recently payed a grand for a descent bottom end plus the carbs have got to be worth a few quid ? The Engine number wouldn’t bother me as in the description it states it has had replacement cases and matches the rolling chassis that the seller has for sale, we blew these up all the time, a friend of mine who drag raced RD400s has a shed full of ported blown barrels, is he not allowed to sell the now because they’ve been ported to run in the 8s ? or does he need to scrap them so non of the restorers are offended 🤣🤣🤣🤣 Am I the only one who dislikes standard stuff ? I’ve a 6 cylinder KH here that runs on 6 stinger spannies 😳 some visitors say, “why would you do that”, because it was done before sad folk bought bikes solely as investments and took the forums over, as was the RD375 engine direct drive kart I recently sold that had its Gearbox cut off 😂 “oh my god why did you do that” 😳😳😳 because it was £200 off an old Hovercraft. 😂😂😂 Going to bike shows I think my generations crazy bikes are now being pampered too much, as for the leave it “it ain’t got matching numbers” devotees, I don’t give a flying F**k about that but to some it’s just a bonus point to make a bike a expensive asset - how sad. The classic bike scene is getting all about final values ££££££ No pioneers of speed and modifying hardly exist. Regarding the carbs it does state they are 28mm at inlet, 28mm at the slide bore and 26mm at the ridge 1/4 down so I’m sure the seller knows how to measure a carb, being a 31W00 European market carb that’s slightly different to the 31K Part number 235446555665566556666566776566677666676/66666666663344457-34/45000 Sorry I’m taking the piss now, Now please sit down for what’s coming next…………….🙈🙈🙈🙈 I ran my last RD hybrid on MK11 Amal’s with powerjets 🤣🤣🤣 I msged him about the liners and restamped cases, he has now updated the ad so at least someone know what their buying. He gives me some shit of the ad but I couldn't give a fook 🤣🤣 |

I think there's 2 kinds of people standard or modified.
The stock riders don't care for speed so much there happy with originality.
The modified riders have more of a need for speed and improvements.
I think they both love these bikes equally and don't want to see people getting shafted hence the call outs on so many times on not right or original parts.
I wonder if it's an age thing the older you get the more standard you want things?
Everyone wants a good running bike some want to push it further. I have a need for speed but I'm only 36 😂

Dont know what you lot are complaining about, apparently dodgy engine numbers can fully justified and explained by the irrelevant paragraph
"....maybe sell your pristine bikes and see the world, we are only custodians of these bikes and there’s more to life than matching numbers - RD500s for example, a awful looking bike when standard but worth good money atm, put that engine in a Spondon frame / now you have a bike, how sad 🙄 "
Not as sad as a buyer would be thats a fact...

The joys of sellers having their ads spoken about and coming to defend them. Been there before, expect we'll be here again now that the bottom of the barrel has been reached for parts and also since all old bike parts are so damn expensive now so its absolutely worth commenting on them as not everyone knows whats good and bad on ebay. No one has unlimited money to waste on expensive junk. As an aside, I also do wonder why if we forumers are all idiots who are obsessed by either NOS/matching numbers or chinese crap then I wonder why its worth coming here and justifying this advert... But I guess we need educating Leaving aside the obvious issues with the parts on sale in the ad, its scary how fast parts prices shot up. How on earth did engine parts become this sort of money? You could buy a whole running bike for this not that long ago, but now this money buys you parts that if you took them to a professional to build for you they would probably tell you to junk most of it. The cases in the advert are likely stolen but of course this cannot be easily proven (and even harder to disprove), yet its the shaving of the old number and restamping of another that is the point here; its not legally allowed and it brings doubt to these parts and any whole bike its fitted in. You dont get to just stamp your own frame number over the old ones if you buy a used engine, you keep the number the replacement engine has on it. It would be churlish to suggest otherwise and if anyone thinks thats ok and allowed then, well... I have no words for you. FWIW Brand new cases come with ridges so banging numbers into a replacement case is possible and allowed, but that's not the case (sic) here. Anyway, the point is that if you spend money and time sorting out an engine build it could all be for nowt if someone later reports the cases (and by default whats inside them and also bolted to them) as stolen. Its not really the cops at this point, they would be less bothered about an 80s bike but maybe that will change if they start getting stolen again now that they are valuable. The point is that its not worth a builder doing this up as it stands as if you try to sell it then the same comments about it being a stolen engine will be made and certainly no one is paying top dollar for a bike with an engine they think might be stolen, and why would they? So, at this point the cases are pretty much worthless and its all about the transmission parts inside... so long as you can live with the fact they are likely stolen. But, not that many of us think its ok to buy stolen parts as that perpetuates more thefts as it creates a market etc. In the 80s it was said racers were ok with stolen parts in their bikes and if you just wanted a running bike ASAP that youd be cool with cases like this. Back then they were the price of a few beers, not 1600 quid. And you still have to be able to sleep at night while not thinking about the person who had their bike nicked and now still has to fund his HP payments after a low insurance payout that means hes riding a used H100 to his YTS job... Ok there are a bunch of other useful looking parts in the advert. Perhaps the stators and the flywheels are useful, but they are a gamble of course. The cylinder head is a goner and needs recutting tho. No one can say that the the cylinders are not a dogs breakfast, no matter if you run these with an amal carb or an OEM mikuni. lol. No professional would be happy to let you run those as is... or possibly ever, as they might not be fixable. The lister of this ad can advertise the parts for any price he likes of course, its his advert. He can sell any old shite or good parts in ay combination he likes. Its all his prerogative. However with that exposure comes the fact that we can in a world of free speech also comment on it like we are doing here. I'd be more interested in this advert if the seller started it as a real auction at £0.01 and let the market decide what this is worth. I do wonder who would buy these parts and what they would choose to do with them and even if those cylinders could be reclaimed at less than a better pair would cost. A thread on the engineering to do that would be really interesting. |

I am afraid I am seeing alot more of this coming into the workshop, people are paying lots of money for engines, I am stripping them for overhaul, then giving the new owner all the bad news that basicallly they have bought the floor sweepings off somebodies garage floor and they need to spend £1500 to get a useable engine, that still has dodgy cases, of course, I get to see alot of mismatched halves of cases too, that is becoming far more widespread.
I am reluctant to build an engine if they are mismatched unless the journals of the bearings etc all clock up within 0.01/0.02mm of each other, most of the parts will tolerate that small difference, but certainly no more, of course the cases have to clmap the bearings, no good if they are like a c**k in a shirt sleeve !
Anyway, buyer beware is all I can say, lots of dodgy people out there, I have an engine I bought years ago, it has the numbers all scratched out, but I only paid a few hundred quid for it, it will get built into a track bike, but the dodgy number will be machined off and the cases left blank, so its obvious, I can't say if they stolen or not, all I can say is I bought them off a good custmer a long time ago who took them out of a hovercraft type contraption !

It’s been removed from sale, maybe it sold? Maybe a change of heart? Too much heat?
Oh and one more thing, now I don’t know the seller or even their identity, however I do know that someone defends the seller on here, whose history shows they re based in Derbyshire and have a connection to motorsport and karting and the seller is Derbyshire based with a connection to motorsport and karting.
Coincidence? Friends?
Who knows? Who cares? Me I’d report to the local old bill, fraud? Handling stolen goods? Theft? Down to the owner to prove they are legitimate.
I don’t care what my have been seen to be defensible by some 40 yrs ago, someone got shafted, I don’t care they were insured, if you want something work for it, save for it like the rest of us do. You don’t get to defend yourself because it’s historic, or because everyone you knew did it, or whatever other justification you can think of.

I'm willing to bet a large amount of cash on the outcome of reporting this to the Police as being like my current account: zero interest. Someone prove me wrong? The problem seems to be someone objecting to negative comments made on here about the advert. Maybe we should adopt a 'If you can't say anything nice don't say anything' policy as regularly advised on FB? Nah, I don't think so either |

I think its more likely that the seller could very well be genuine, but not as knowledgeable as us old farts. As I have stated above, I have a motor with dodgy numbers, yes I am aware of it and yes they will get removed to make it clear they aren't right, but I am in the know, if you buy a Japanese bike, most of the cases only have the model number on them, e.g. 4L0, 29L etc, etc.
Of course there are some very dodgy geezers out there and we have a list of those we are aware of, its available for all to see, I think we are all guilty of falling into the trap of assuming anybody selling or trying to sell something with dodgy numbers is dodgy themselves, but if I decided to sell that YPVS motor above, with the relevant description to match its status, how many on here would call me dodgy ?
I like alot of people, are quick to judge, too quick sometimes, as I get older I am certainly getting more cynical, which can be a good thing, but can sometimes condenm people who are in all honesty just genuine people who aren't as knowledgeable as us older people
All that said and done, as stated before "buyer be aware" - I was always taught, as a seller you only need one pair of eyes, firmly fixed on the buyer, as a buyer you need a 1000 pairs of eyes to check everything
Right, back to porting some cylinders.................

My valve, which I've owned for more than 15 years, has a badly restamped set of Brazilian cases. It's been restamped to match the frame & original engine number.
However in the previous owners defence, or the owner before him I think, I do have the receipt from a breaker for the motor.
I wish that they hadn't bothered, but I can live with it & don't consider it devalues my bike, but then again I have no plans to sell it. If I ever do sell it, I'll make it clear in the advert.

Everything has a value, even an engine with dodgy stamped cases and re-sleeved barrels. My opinion is that value is not as high as that sellers. For that reason, I'm out Increased cynicism seems to come with age although I do think I've got more tolerant of a lot of things as I've got older. Are they opposites? I'm not sure  |

Not even £650. Maybe at £150 if it was up our street.
