God bless you Allen. Your videos are so well done with a beautiful cadence. I get lost in the moment watching them and when they are over, wish there was more. I have learned so much from watching you work, and I will never discount the importance of a hacksaw or barbque pit ever again.

[@doublenickel1000]

You've hit upon the word--"cadence". Yes. That describes his delivery/photography/technical work/observation of wildlife/showcasing Tracy's kitchen skills/etc. perfectly. Bravo.

[@Supercell725]

Watching Allen rebore a cylinder head is more entertaining than anything on tv in the states.

[@slartybartfarst9737]

Allen got me again, I've always wanted to know how those reboring machines got the bore aligned especially as I've painstakingly rebored on a lathe in the past which included turning a flange on a faceplate to avoid chucking the barrels. That's me screwed I want a reboring machine now. Brilliant camera work showing the exact view that describes the process........ with cake and robins for good measure!

[@utubedaveg]

I just bought a Bridgeport milling machine. I assume with the right setup i can bore a cylinder. I am overhauling an s4 kawasaki.

[@slartybartfarst9737]

@@utubedaveg with something as substantial as a Bridgeport you can bore a cylinder with a substantial boring head (adjustable radious cutting) and clock it to centre dead ctr or you can make your own ideally you need some mass in the tool to minimise vibrations off the ports if it's 2 stroke barrels, 4 stroke is easy almost any boring tool will do the job

[@GT380man]

Allen’s technique with the circlip pliers is so well controlled that I noticed he didn’t even block up the open bottom end. I always do, because I often drop the darned circlip!

[@rogerbarrett9920]

Haha - Even though I've built many engines I still cover up the crankcase, the thought of dropping the circlip makes my hands shake!!

[@epj900]

Hello Dr Yeadon!

[@_pld]

I like how none of the circlips are lined up the same way, one horizontal, another vertical, no rhyme or reason, just do whatever you feel like!

[@shelleyking8450]

So calm and organized, with a beautiful result. Allen is the British Bob Ross of "men in a shed" mechanics. It makes me feel like I could do wnat he does, even if I know better.

[@r1273m]

That was fascinating, I have never seen a rebore done before. I thought that getting the barrel central would be more complex than that 3 pin system.

[@MaciusSzwed]

You´ve never watched Pakistan mechanics? Check em out, they are not as precise and inventive as Allen though...

Allen thanks to you the mystery of cylinder boring is de-mistified . Thank you. I appreciate your videos sooo much. You explain things so simply and beautifully. Your filming and editing is just as simple and elegant as your bike building. That in itself is a craft. I love the contrast of your machine work with the appreciation of your wife’s baking and intercuts of squirrels, birds or what ever. Your ‘Boyish’ enthusiasm is infectious. I use music to relax and now I use your videos to do the same only in a mechanical way. Any project you accomplish always makes anything I do seem like a Piece of Cake.

Hands up who’s done both of those. Hmm. I have! Tell you what, though. You don’t do it twice.

I was wondering why there was no rag to stop the circlip falling into the crankcase, I wouldn't have dared fit them without.

Was surprised an the no rag confidence or even cow magnets . Took 1/2 a day with my clumsy mitts once. It can become an interesting fishing operation !!! Ole man Murphy's Law . If it can't possibly happen it will !!! Some magnetic tools are a great confidence builder.Especually with tiny parts.

I cannot get enough of this. I have a 2018 Honda CB650F and a 2007 Suzuki GSXR1000. I work in motorcycle insurance, at a company that is popular with classic bike owners. I've been interested in getting my hands dirty, but approaching my bikes with a spanner as a 31 year old newcomer is daunting. Taking an allen key to my bike the first time resulted in a broken bolt, so I've been reluctant since. I have a handy friend who has helped me with a few things and is currently rebuilding his 955i Daytona after an accident. Your channel has truly inspired me to keep getting them spanners out, thank you

[@philtucker1224]

Allen you’re absolutely right about those sleeve bolts, they look absolutely pristine on the top of those cylinder heads! (Can’t wait to see the episode where you make the exhaust headers) - this engine is gorgeous. Nice work 👍😊

Hey Allen, I forgot to add. I love the old Cylinder Boring Machine, and you got all the original tooling with it. We have simular in Australia that would sit on top of the engine block like yours and were made by REPCO, could do a 6 cylinder car ehgine with one. I've never seen the stand that you have for doing Bike Barrels. Very nice.

They work just fine on multi cylinder blocks as well just screw a large headed bolt into a head stud thread. spent many hours watching them make swarf our shop had a couple of them on top of the motor there is a diamond lap to sharpen the cutters.

[@peterlavin9373]

Really enjoyed this episode Allen. Did you find any variation in each of the pistons and did you need to gap the rings in each bore?

[@GT380man]

I too wondered that, the dimensions. I will say the OEM Suzuki two stroke pistons for their triples like the 380 come up incredibly similar. Not totally identical. What I’ve noticed can vary quite a lot is their masses. I think they must have changed the alloy between the 1970s & now. So it’s well worth checking, especially as in this case, Allen had one piston in stock & bought three more. If the stock piston was decades old & the set of three were recently manufactured, its possible they have different masses.

[@Bobby-fj8mk]

@@GT380man - I noticed that he didn't weigh them to check. If that one piston was a different weight it would cause vibration. He also should have put a rag in the top of the crankcase in case a circlip fell in. That saved my bacon many times.

That boring machine is absolutely fantastic what a cool tool to have and still perfect after all these years

[@bobstevens9040]

Great to see Allen using Sheffield made measuring instruments. Moore & Wright micrometers were made in Sheffield from 1906 but the factory has moved to Bradford now after a takeover. The boring machine toolkit was made by GKN in their Laycock engineering plant also in Sheffield , now no longer with us , although GKN still has a presence in Britain.
