Hi Craig. My reaction to what I have seen is that as the valves are so clean that some one has obviously been in there to do some work. Perhaps something happened like the end of a spark plug broke off or it dropped a valve, I'm thinking that because of the marks on the top of the piston. The other thing I would definitely do would be take the barrel of and inspect the piston rings for wear or breakages, if there reusable then hone the bore to get rid of those nasty marks so the rings, if in good condition , can be run in nicely. would be silly not to at this stage. Just my thoughts. All the best Mike. 👍

[@andystokes8702]

If it were mine having got this far with stripping it down I would at the very least have the barrel off to check the rings. It won't be the piston catching in the bore, it will be the rings and at this point it's only a couple of minutes to do. It would be a shame to put it back together, put it in the bike and then find there's poor compression because of a broken ring which might cause further damage to the bore.

[@richardsiddon610]

😂 “My mind is a whirl”…. Name that film..

[@richardlinsey2419]

A little bit of a hone and I think that bore will be fine providing the piston skirt is clean and obviously showing no signs of scoring, B.S.A. singles a pretty robust motors. 👍🏻🇬🇧

[@Cobra427Veight]

Hopefully they haven't assembled the crank with grease , it doesn't dissolve very easy .

[@allanrichards3752]

I think that bore looks as if it hasn't seen much running. I would take it to an engine builder and have them give the bore a light hone. I would then buy a new set of rings and put it back together. Perhaps pop the valves and check how good they are whilst the head is off.

[@rickburnout666]

My old garden find (no barnes found here)XT350 was so siezed that the kickstart shaft snapped when somebody tried to kick it, it had been sitting with no carbs fitted for years but after a few days with WD40 & plenty of tea , i put a spanner on the crank and it moved, and got the bike running after i got hold of a kickstart shaft, the engine will get stripped down eventuly. Kèep up the good work !!

[@nickmarshall9192]

I'd definitely just give it a light hone and put it back together Plus if you lift the barrel you can check the big end Also sometimes you get corrosion on the valve seats so I'd at least fill the combustion chamber with petrol to make sure they are still good Cheers

[@elmerfudd1086]

Craig, you really need to get that extension built on your shop. I know I will keep watching even if it is building a shed rather than a bike. My shop is a shed so I would be quite interested to see your ideas.

hone the cylinder out and put new rings in it just a thought 🤔

[@HepcatHarley]

First

[@zweispurmopped]

Maybe try with some acetone if you get that ridge away. From over here, it looks like contact corrosion and pitting. Time for a full overhaul. That engine is too precious to wreck it with half done jobs.

put it back together and check compression, you may not have to hone it...but....you probably should right?

[@bigred8438]

Oil, plus condensation, equals thick brown/rusty coloured grease 🤣😅😂

[@geraldswain3259]

Why do people keep advising Craig what to do, He knows exactly what he would do. He is a perfectionist but he is doing it for someone else and waiting for their go ahead. He has forgotten more than most you lot know. Jeeeez.!.

[@alstone5257]

Hello Craig. I was wondering dose the older BSA use Whitworth tools like Triumph ? If They do they are available, new from Lowbrow Customs. The price seem fair.

[@TheOldaz1]

Definitely have to pull the barrel, at very least a good honing needed. Shame when you find stuff like this after someone has done some work on it, because you never know how far to go to be sure it's going to be OK. Thanks Craig.

[@billrandell4641]

Such a sweet old engine..I'd bore or bore and sleeve..They are getting so rare, folks are rebuilding junk..I'd give my left nut to find one like that over here..👍🗽🇺🇸

[@ianedwards759]

Your right Craig it is a special moment, I'm in a hotel in France, can't sleep, TV is full of French people talking (believe it or not) that I don't understand and then your vid pops up, your a saviour 😂

[@JohnSmith-ch9lp]

Not a short one a perfect length for a vid. By the way do you still have the GSX1100 turbo project on the go?

[@750triton]

Consensus here has taken the words out of my mouth. I had a 500 (B33) for many years. Pushrod tower is 2 nuts and it's off, barrel slides off and you can check big end (Last forever) and yes, get the bore glaze busted and some new rings. Looks like someone has allowed or didn't notice the magdyno strap came loose as the slots the dowels fit in have been worn round. Those engines will run on TVO (tractor vapourising Oil). I can't remember the ratio now but I think it was petrol and 20% parafin

[@simon2knine]

It's down to Mark but if it were mine.....At least take the barrel off and do some checking.

[@brockett]

So easy to strip those engines that it would be a shame not to. If it was mine...... I'd be thinking hone or rebore?

[@markarnold5593]

Cor Blimey, I had one just like that as a door stop in my kitchen for about 5 or 6 years.... ;-) ;-)

[@whylie74]

Why would you put grease on a piston? perhaps to give who ever bought the engine a smokey surprise the first time they fired it up.

[@sidwainhouse]

TBH I'd go down the reboot route, lap the valves etc. Might only be a bitsa but it makes sense to do it now and get more life out of it. Easy fix though unlike any seized engine I've had... 🤣

[@stephenfrench4417]

i reckon well yes guessing hone the bore clean the piston new rings and it should be good to go without a rebore DO NOT media blast it

[@joekerska4640]

A small piece of carbon could have stopped the piston in the bore and the oil might have softened it enough to get by.

[@aspectcarl]

< Alarm going off > best set that camp bed up in the shed then Craig 😂

A Craig just noticed something you’re sine in the shed it used to say first time it now says 2nd 3rd or 4th time that’s you changing your mind me owd mate

[@alandavies55]

Looks quite good for an old Beezer single, most of them were run until completely worn out.

[@ARIELVB]

Have a look at the piston rings , might as well has its down . You cannot beat the old stuff, built to last .

may have been a hydraulic lock ?

Wipe over with WD40 and bolt it back up.

[@westers1514]

Has Mr D Boy been in there and buttered the piston up to stop it seizing?

[@berniebne8243]

I don't normally comment as you are normally working on a level that is beyond my abilities. This time it is not the case I must have pulled a hundred of those engines apart as a penniless teenager. You could buy one for a fiver. You are only 5 minutes away from removing the bore & piston. Then a clean-up of the ring grooves etc. and I'll bet the rings are in spec. check the bottom end and it'll probably run for years. It's the right thing to do & costs bugger all. All the best.

[@deandee8082]

yea I really doubt you can bore out that sherman tank gun barrel chunk someone used for a cylinder, sheesh, what is that 5/8ths" thick? that's insane, you could bore half that away and still be way over engineered, last time I seen a pipe that thick was ona sherman tank canon.. jeez

Morning Craig. You did make me laugh...I saw the glint in your eye...you wanna build it! Lol. Brilliant as always.

[@williamstewartbuchanan5299]

Hi Craig, I concur with the other commenters here but would add that the build up (grease) you've encountered may be an early form of assembly lube! I saw this recently on a car engine on another youtube channel, Barum Engines. The fluid evaporates over time and leaves a sticky residue. Hope this may shed some light. Cheers for the channel, keep up the good work.

[@minigpracing3068]

How much will it really cost to go through that motor and fix it? Hone the cylinder, new rings, new gaskets, and maybe a bearing or two? Worst case the cylinder needs to be replaced. I'd hate to see it go from bad to completely wrecked for the fairly small amount of money needed to fix it.

[@badjuju6563]

Was the grease actually cosmoline and sptayed in as a rust preventitave? new rings, hone the bore and send it...

[@valvegeek]

Fascinating, thanks for that. Reminds me I was advised if leaving an engine for a while, turn it over until at the end of the compression stroke (relatively easy to do by feel with a kick starter), where the piston will be at the top and both valves are shut. Nowt can get in from outside (via the valves) and the bore is mostly only open to the crank case. Altho it only works for singles, or parallel or flat twins where both pistons are at the same position. For the 'other side', that's not on compression, the valves would be exhaust nearly closed and inlet just opening, so almost the same and still better than a wide open valve. 😁

[@paulelberfeld8525]

Hi Craig, I’m sure you can make a ‘C’ spanner with your talent😬

[@GTMarmot]

I watch Paul Henshaw and with those BSA engines he usually sticks a big mole grip on the end of the crank and gives it a wiggle to check if there's too much free play.

[@iamthefatstig]

Our Redex is basically the same as the famous Marvel mystery oil, pop that in the bore next time.

[@neil1150]

I'd check a valve seat, then hone the bore, maybe new rings and ride it.

[@jonathanclark6764]

Ya gotta pop the lid mate just for peace of mind

[@glynprice3815]

For some reason I'm always drawn to the BTU 82 B number plate behind you Craig. Do you know where it came from?

[@David_Walker16-3-51]

Looks like a BFG plate, British Forces Germany. Issued to service personnel serving in Germany up until the early 1970’s. The distinctive plates marked them out as potential IRA targets so after that, right hand drive vehicles got a standard UK plate and left hookers got a German plate. I made the mistake of buying a nice 1956 oval window VW still on BFG plates, sadly I didn’t get the necessary documentation to re register it in the UK. Eventually, I let it go, at a loss to a bloke who had no scruples and promptly “rung” the car with a UK registered scrapper.

[@stevewilliams5428]

That's a specialist copper grease in that there cylinder. You can't get it anymore it used to be made by delboy.

[@nightster6378]

Dead original, never heard anything like that about Del before.

[@michaelsmith-pl5kl]

Nightster these people don't have any thing decent to say but criticise other people.

[@nightster6378]

@Eddie Hitler Firstly I apologise too Craig for my view on his channel. Of course I know I can ignore it Eddie but people make the same comments time and time again and fall about with laughter each time they hear it, it appears is a tad childish so I'm not sure why should I ignore them. A joke can be hilariously funny the first time, after repeated by the originator 40 maybe 50 times or more they deserves little more than a grimace at best. When repeated by others after years thinking it's still hilarious just to gain a little heart to their comment, to raise a smirk is more than enough and thats only due to the idiocy of who makes the comment especially by the over 12-year-olds who think they're grown up's. Maybe idiocy is harsh and infantile is a better description. I also enjoy the comments I make usually to expose a narcissist, similar to the narcissist who enjoys entertaining his audience trying to destroy other channels and insult their viewers, and not only one channel having set himself up as the KZbin Police out to protect everyone from harm. OUR HERO. I also enjoy the hypocrisy and lies from the same narcissist who claims he does not remove comments and blocking comments from being made on his channel then when called to question can't handle the truth. Just like when asked when he is going to build something better than the ordinary Allen Millyard a challenge he accepted and Delboy challenge he made and is yet to do. Putting his name in front of a designers name an engineer who designed an engine 40 years ago and puts claim to it after making a few plastic parts on a cheap 3D printer and loads of promises. To get told to kcuf off when called out for taking the piss out of people with Parkinson's disease, down syndrome, or those of a lesser education. I guess I can see why he hates me LOL. I consider getting blocked from making comments and having my comments removed an achievement and a victory especially after my invitation to meet with him in person was ignored therefore not accepted.

[@nightster6378]

[@fabpeter9764]

Judging by the ease with which it came apart, I think somebody, probably years ago, knowing it was going to be unused for ages, stripped it, cleaned it up, greased it (to prevent corrosion) and re-assembled it, fairly loosely. Their thinking.......possibly........re-assemble to keep all the bits together......greased to prevent corrosion in storage.....if required at a later date, strip, clean out, re-assemble correctly to re-commission. Just my guess, but it makes some sense methinks. Could do with a "glaze bust" in the bore at the very least.

[@nightster6378]

I totally agree with you! I have seen grease used in a bore in the past, oil can dry out and light rust appear.

[@fabpeter9764]

@@nightster6378 Yup, I'm a rifle shooter and some of the stuff manufacturers put in their new barrels to prevent corrosion?........well it can be like candle wax sometimes! If you shoot these rifles without pre-cleaning, you'd run the risk of blowing your rifle and probably your head off!

[@nightster6378]

Its great to see "you especially" fired up like that couldn't happen to a better guy, seeing the end of projects and start of new ones especially diversifying from the Enfield's is probably helping, myself looking forward to the Ural. It was good there was little issues with the engine but you should know most old British bike owners especially in the day will use them till they near stop, some of us intervene before it stops. Im also fired up at the moment just finishing a shed 26'x12' with a 9' door on the side allowing great in and out access, built by myself over the last year to house my best bikes meaning 'as in your case' I won't have to wheel 4 bikes out to get to the one on the lift, after a days work this can be a chore especially as I have to manoeuvre them around a Frogeye Sprite I just put a 1275 engine and gearbox into but still on axle stands and in the way. The last vid on the seat you made was excellent and made to look easy. Im looking forward to Dan collecting his bike maybe this weekend?

Clicked the like button before I watched it, I'd be tempted to pull the cylinder off and look at the rings, could be gummed up with the what looks like grease and rust, looks like it's had some water ingress down the inlet port when the valve was left open. Or Del's been there!!!

The mark is close to the bottom of the stroke so give the barrel a hone and put it back together. No point doing more until you see how it runs.
