Part 15 - Royal Enfield Classic 350 Reborn Performance Camshaft & Make Your Own Torque Wrench!

[@HouseholdDog]

Great video. It's like witnessing a watchmaker work on a motorcycle engine.

[@GlynOC]

Wow, thanks!

[@Trev350]

Those roller cam followers are beautiful quality. Love these 350 engines.

[@GlynOC]

Yes they are!

[@simonchilli2088]

A lesson in sharing, engine upgrades and physics...excellent.

[@GlynOC]

Glad you enjoyed it Simon

[@HouseholdDog]

It looks very modern inside.

[@GlynOC]

It's a super up to date engine for sure! Must be one of the most modern air cooled motors there is, everyone else has moved onto water cooling!

[@MerciaMoto]

Superb video, a pleasure to see the care and attention you've taken with fitting the cam and a free physics lesson thrown in! 😀 Thanks Glyn 👍

[@GlynOC]

Thanks very much, I hope it was correct! 🫢 Thanks very much for your comment

[@jimporter]

Have you considered fitting the Hunter 350 throttle body? I have seen a video where this was done as the scuttle but is that as the throttle body includes the ECU that it is not restricted in the same way and you get an extra few mph.

[@GlynOC]

I've been reading about that, I'm not sure it works on the Classic but will keep an eye on it

[@sidweazel2883]

What a superb video, kept me fully engaged. Very pleased you kept in the bits that didn’t go so smoothly which keeps it real. First class mechanics, presentation and videography. 👍

[@GlynOC]

Thanks very much, 'the devil is in the detail' is such a cliche but such a well earned one!

[@sa4555]

Brilliant video. Right now I am in the planning phases of getting a classic 350 and the camshaft replacement woukd be the first upgrade I would do. Great work.

[@GlynOC]

Good choice!

[@Walt_G]

A nice and slow how to video with plenty of detail, problems and all. Looking forward to seeing this bike out on the roads.

[@GlynOC]

Thanks 👍 It went back on its wheels today so that's great, the weather is a good motivator when it's nice

[@davydavidson2421]

Another great video Glyn, I especially appreciated your calmness when the crank tool wouldn't fit, I'd have been swearing like a sergeant major on the marching square🙃

[@GlynOC]

haha somehow I knew trouble was on the way, it was just a matter of when. I try and expect only 50% to go my way then I'm not disappointed when something happens 👍

[@HouseholdDog]

I was yelling "use a hammer" at the screen. I might add. This is not professional advice.

[@philpeacock7803]

Great job Glyn. My hitchcocks locking pin was the same, had to file it down to fit. You were lucky with the top cam lock tool. Mine were over sized, so had to file both pins to fit. A few guys have had the same problems. Your bikes coming on well. Yet again another great video. Thanks.

[@GlynOC]

ahh it wasn't just me then. I thought I must have gone down a very wrong path. You can see the locking hole through that hole so might have been able to lock it up with a suitable smaller bolt and some insulation tape. I'm glad the cam lock worked!

[@TheNorfolkThunderbolt]

Excellent video! Thanks for the mention! Looking forward to seeing how well it goes!

[@GlynOC]

Thanks Steven, me too. Won't be too long now 👍

[@johnimmins7302]

Brilliant video. 👍

[@GlynOC]

Thank you! 👍

[@andrewmeadows1288]

Great to see you back..😊

[@GlynOC]

Thank you! 😃

[@petejones1957]

Excellent video Glyn da iawn! great explanation of the torque wrench, remember years ago welding two bits of square section steel ( from a door handle) into an L shape, and using a "Little samson" fishing spring balance to set the torque on a cam belt tensioner in my old Citroen BX, all ft/pounds in those days!, worked a treat! Look forward to seeing the bike back together again. Stay safe....Pete

[@GlynOC]

Thanks Pete, it was a lot easier to work on them then when you could get near the dirty bit without taking all the front to bits. The BX was an awesome car! Wheels are back on the bike now so you should see that this week👍

[@tigerness5555]

Excellent video Glynn, plenty of detail and close up shots to allow others to tackle the job for themselves 👍 Does Coastrider’s, mine and now your video make us now a trio of experts in this field now 🤣

[@GlynOC]

Thanks very much, I had your vid in the background and was most jealous of how well your locking pin worked, I thought I was going mad. I think if you watch all three, there can't be much left to catch anyone out! best regards, Glyn 👍

[@droptuned83]

Nice job and lovely looking lump. Im so wanting a 350 after all your video's, I really want a bullet I think.

[@GlynOC]

They're wonderful machines and amazing value, the monthly payments are pocket money really and you know it's going to last for years and years. Some owners in India are well over 50k miles without problems

[@davidrawlings3460]

Excellent video as usual.

[@GlynOC]

Thanks David, it better start 😅

[@ericmehl904]

Bonjour à vous depuis la France Je me suis offert une Royal Enfield 350 Classic au mois de juin 2024 …. J’ai actuellement 1300 km au compteur… J’ai également acheté un nouveau arbre à cames de chez Hitchcock…. Pensez-vous que je puisse le monter dès maintenant ? Ou vaut il mieux que j’attende d’avoir plus de kilomètres au compteur ??? Pour la petite histoire, j’ai déjà remplacé le filtre à air et enlevé le pot catalytique…. Bien à vous , et encore merci pour vos conseils toujours bien expliqué 😊

[@GlynOC]

Merci! Si le moteur est souple et fonctionne facilement sans forcer, je pense que tout ira bien. En cas de doute, laissez-le peut-être jusqu'à 1 000 milles - 1 600 km. Merci d'avoir regardé, Glyn

[@berryslokker8949]

Hi glyn. Love this video. I did the camshaft last month (with help of tiger ness video). I dropped the chain so had to find tdc again. I got the stainless steel tool from hitchcock and that fitted perfect. You will notice the difference, especcially going up a hill. As allways, thanks for this and hope to see you drive this bice soon. I keep up following the progress. Berry

[@GlynOC]

Thanks Berry, I'm looking forward to it and hoping for big progress on the next video putting it all back together, or as much as I can!

[@tedcase9175]

Thanks Glynn,well what can I say interesting to say the least,took me back a bit 10 years actually to when I was working as a mechanical technical instructor in the nuclear industry, did all that torque tightening technique with the lads n lasses, interestingly use a spring balance for sideways pull at 1mtr, there are of course many ways to ensure correct stretch of a fastener to within its elastic limits, and it all came back,thank you again cannot wait for next instalment,Ted NW biker dude alias Bay Bimbler

[@GlynOC]

Of course, a spring balance, that would be far better than a bottle of shampoo. I wish I'd mentioned it. I hope it doesn't come apart after all those checks, that would be really unfair! Thanks very much for watching and stopping by, Glyn

[@adityahandu1008]

Hi Glyn, can these changes be done in the older engines aswell ? The ones in the 2012 to 2015?

[@GlynOC]

Hello, I'm not sure. I think they have a cam for the Himalayan? If you check the Hitchcocks UK website, that will tell you for sure

[@lesterhall5310]

Love your stuff. Lester Australia.

[@GlynOC]

Thanks Lester, always appreciate you stopping by 👍

[@patrickobrien2068]

Excellent video! I'm about to try this procesure. First time for something this involved on a bike. If the TDC had been off at the cam before bolting the sprocket back on, how to correct?

[@GlynOC]

The sprocket can move on the bolts so lots of adjustment, just get the crank in the right place with the tool or by looking through the hole and lining up the lock hole (down by the crank), then fix the cam so that the hole on it goes straight upwards (using lock tool or a handy rod/eye. Make sure the chain is tight at the front as in the video👍

[@candidosteeley]

Seem's like a common problem with that crank lock tool. TheSmoaksVlogs had same issue he used a #3 Stanley phillips screwdriver, fit perfectly imagine that. Thank's for your video's learned alot.

[@GlynOC]

I was really surprised, it wasn't just slightly wrong, it was way too big, and bloody hard metal too!

[@droneon29]

Loved the video, at least now your timing is spot on, very strange how the crank locking tool was oversized, but you sorted it, if i ever do my cam i think ill stick a brill bit in 😂, be interesting to see how the cam changes the performance of the bike, i was going to do the same on my Himalayan, but since reducing the rear sprocket by two teeth im so impressed i decided not to change the cam, love the torque wrench....... Colin ☺️

[@GlynOC]

Thanks Colin, how's your storm season going? A drill bit would be absolutely fine, you can see the hole through the outer case and could easily do a visual check too, probably the same with the top too, if you stuck a bit in it and made sure it was perpendicular to the head. Cheers, Glyn 👍

[@droneon29]

Hi Glyn, yes it seems at long last we may be riding ourselves of the storms, although Finistère is well known for the wind 🌬️, looking forward to the rebuild, take care ...... Colin ☺️

[@davidn1562]

on the clutch cover what is the clutch shaft correct position?

[@GlynOC]

The shaft has an endless set of teeth on the bottom and splines on top, it doesn't matter where it is, you just put the clutch arm on the splines on top when you're ready to fit the cable 👍

[@davidn1562]

@@GlynOC Thank You so much, waiting for cam to come back on stock

[@johnkelly2279]

Lad!!! did you consider the weight of the pipe,in your calculations????

[@GlynOC]

haha I did not but it was very light to be fair🤪

[@oliveirasegantine3879]

Onde comprou essa peça que colocou? Aqui chamamos de comando de válvulas, não sei se a tradução terá sentido para você.

[@GlynOC]

Olá! Coloquei o link na descrição agora, chamamos de árvore de cames. Obrigado por assistir!

[@xolivier8156]

Quelle est le gains en performance et chevaux

[@GlynOC]

Approx 3-4hp I think

[@2011ppower]

Funny how no one mentions notifying your insurer about these mods🤔

[@GlynOC]

I'm not sure they'd believe me! "You went to Screwfix for what?????" 🤪

[@jayaprakashnarayanaa]

Can you please list all the tools you have used including electric tools?

[@GlynOC]

I'll try and make a list for you, but it's essentially a 5mm allen drive, 10mm spanner/torque wrench and the special tools, I'll try and make a better list for you!

[@cleeveofford1720]

How long have you had the cam? Hitchcocks are out of stock apparently or can you get them from somewhere else? Excellent vid, can’t wait to get my hands on a cam for my classic

[@GlynOC]

I got it in Feb when they popped up for a while, the site says they'll be back in May so keep an eye on it 👍

[@weemark67]

Glyn, may I suggest that you put Royal Enfield Classic350 Reborn, at the start of title?😊

[@GlynOC]

Good idea 💡

[@Trev350]

Don't forget that the 1m long rod/tube also has a mass that you must take into consideration. The weight of that rod is also acting to turn the bolt. So you in fact applied 9.81 newtons plus the weight of the rod to torque the bolt. If your 1m long rod was heavy enough, you wouldn't even need the bottle of water.

[@GlynOC]

oh yes, I forgot about that! Good thinking 👍 Hopefully it will not need to come out again

[@jez6208]

Looks like Hitchcocks screwed up there. Or RE. 🤔 fascinating as usual. Thanks mate. 👍

[@GlynOC]

Thanks Jez, I will never say something should be straightforward ever again!!

[@mikehatswell3961]

Just checking Glyn but did you torque the cam/ cam chain sprocket bolts? Because it’s not on the video 😮 still a cracking video, all the best buddy 👍

[@GlynOC]

Yes,I did but the camera went out of focus so I skipped showing it, good eye! Thanks for checking 👍

[@mikehatswell3961]

@@GlynOC though you probably did but it’s a easy mistake to do especially when you’re also concentrating on filming it, great series buddy 👍

[@weemark67]

Fantastic work Glyn. Your attention to detail, and explanation as you proceed is first class. I would be bricking it 😂 Looking forward to get Bumble back, this Friday 😊 But it easy on hour n 20 ride home. Then in the next few days following hopefully do an update, as to how cam feels. Also got the unrestricted throttle body coming. Most enjoyable watch Glyn…..cheers

[@GlynOC]

@weemark67 Thanks Mark, I bet you can't wait to get yours back and look forward to hearing your thoughts on your new setup. Cheers, Glyn

[@johnrutherford4276]

Another fantastic video Glyn. Thank you- very much appreciated. Both your RE's are going to be amazing! 🙏👍

[@stevenmiller184]

remarkable. Easier to do this job with the engine out of the bike, obviously.

[@GlynOC]

Good access makes everything easier doesn't it, nothing worse than struggling to see what you're doing👍

[@imarider2389]

Hi,am from India I watch all your videos. I am a Classic Re Born owner.After running the bike for a while, when I give acceleration, I don't get the throttle response according to the sound. It has good engine oil. (Reaching the pocket road ;downshift and giving the accelerator may not pick up.) What could be the reason? PLEASE REPLY 🙏

[@GlynOC]

Hello! That's strange, has it always been like that or is this a new thing?

[@imarider2389]

@@GlynOC It has been there since the beginning. I believe it could be a clutch issue.

[@GlynOC]

That is a good guess, I'd start there

[@Anatol.Junior]

Put four valves in there

[@oliveirasegantine3879]

O que seria "hitchococks? Sou do Brasil e a tradição do Google tradutor não faz sentido.

[@Ijusthopeitsquick]

You ignored the mass of the pole itself.

[@GlynOC]

My maths isn't good enough so I ignored that bit🤪

[@Ijusthopeitsquick]

@@GlynOC My maths is no better but I would guess it would exert a torque equal to the mass of the pole times half its length, assuming it's the same diameter along its whole length. I like your channel btw.

[@GlynOC]

@@Ijusthopeitsquick Thanks very much and I think that's a very good guess, maybe even 100% right! Cheers, Glyn

[@Ijusthopeitsquick]

@@GlynOC I just weighed a steel rod then perched one end of it on the scales and the other end on a block at the same height as the scales. The scales read almost exactly half, so it seems my guess was about right. Thanks for motivating me to test the equation!

[@GlynOC]

@@Ijusthopeitsquick That is brilliant! Thanks for coming back to tell me 😁

[@hunterrider349]

another enjoyable video, looking forward to to the next thrilling episode, ps, the cheaper silver crank locking pin fits with no mods 😊

[@GlynOC]

haha typical, hopefully people will be forewarned now, maybe I should tell Hitchcocks but they might tell me I'm doing it wrong 😜

[@RustyOrange71]

The question that springs to mind is: why are Hitchcock's still selling these specialist tools if they are proven to be such imprecise junk?

[@GlynOC]

It might be that people are buying the cheaper, non-original version they sell and that works fine and the people who buy the genuine part just work around it and never say anything. I wasn't the owner of this set 👍

[@RustyOrange71]

@GlynOC Thanks Glyn for this amazing set of videos. I'm not an engineer but, human nature being what it is, you may be right. Surprised that Hitchcock's haven't noticed... feels like they're pulling a fast one... stock they have to shift, maybe? Oh well. Thanks again for your passion and hard work. Guys like you are an inspiration.

[@GlynOC]

Thanks for your kind comments. it's surprising how many things that have massive design faults seem to persist for so long, even with modern tech. Anyone who's owned a British Leyland motor product will know about that 🤪

[@jez6208]

So, here's a few. Why are you choosing Royal Enfield 350's to work on? Why not a 650 or a different brand? Lastly, would you sell the bikes you've worked on? I suppose you'd only get book value which would be pants after all the time and money you've put in. Anyway, I'd like to hear your thoughts. Keep up the good work mate. 😊

[@GlynOC]

ahh well, I guess for the same reason everyone watches Classic 350 videos! There's just something about them isn't there and I can't be doing with an old one with carbs and whatnot, the new injected ones start and run so nicely. They're the best value too, I'd like a Harley project but even old junkers cost as much as a nearly new Classic! Interceptor would be great but they don't come up often and I can't think of anything I want to do to one that hasn't already been done. Def not for sale, I'd rather just sit on them at home🤪

[@jez6208]

@@GlynOC still, if you get a written off interceptor or any of the 650's, I reckon you could come up with something. 😄👍

[@GlynOC]

I do keep an eye out and there's an Interceptor auction finishing later but it's already over £2k and it's a complete dog, needs total refinishing and rebuild and it's just not worth it now unless you really want it. I have got an idea for the next one though🤪
