2 greatest movies ever made; On Any Sunday and Triumph 650 Motorcycle Engine Disassembly & Rebuild - Lowbrow Customs

[@chrischarles27989]

Thanks Lowbrow customs you can see a huge amount of time and effort go into making these videos which every appreciates. With the help of Todd I have customised my sportster and done all those jobs that a shop would charge strong money for. Now I am in the process of getting a TR6 Trophy and have no worries thanks to this video. I would love to see a couple more videos on the maintenance side of the old Triumph bikes. Thanks Again from the UK 👍

[@TheStephepps]

We certainly could have used the internet and you back in the early 80s when I rode Tigers and Bonnevilles from the 60s. Great series I enjoyed it especially for nostalgic reasons. You are truly a master craftsman at your art. If I ever come across another of those old machines you will be hearing from me.

[@JesusTorres-qr1gz]

Gentleman, CONGRATULATIONS, I enjoyed every second of it, the last time that I put my hands on a triumph was in 1972, but at my 71 years of age I still enjoy it like the first time, to you and each and every one that one way or another made it possible for us to enjoy it my most expressive thanks, blessings to you and your love ones, from the endless summer paradise Puerto Rico Jesus Torres.

[@MatthewBaca-o9t]

Top notch work . I've watch this video through and through twice. Just picked up my T120 the other day going to need work. Plan on getting parts from you as needed. Thanks .

[@philipdirden5670]

Enjoyed the series, good tips and short cuts. Wished you had this back in the 80's when I bought my basket case 72 T120R, I had to do it with magazines and factory manual!!! Thanks :)

[@derekbowler6077]

Great easy to follow instructions thanks Todd

[@chrisnix4276]

i have spent a very enjoyable weekend rebuilding a friends t120/r engine watching your videos as i went along,well done and many thanks from south spain.

[@MrSantacruzz]

Excellent work Todd, you have created the definitive “go to” video of a Triumph twin rebuild that makes it possible for us amateur mechanics to keep our machines on the road. Truly inspiring!

[@paulfoster5432]

I am from Yorkshire, England UK 🇬🇧 And I have throughly enjoyed watching this 13 part series on the Triumph, I aren't a mechanic, I've been riding motorcycles 46 years now, I'm a bit of a frustrated mechanic, I must say it's been a pleasure to watch your grand master machanic at work, I mainly do oil changes and such, Over the years I have owned 30 different types of all sizes of Motorcycles, I currently own a Royal Enfield 650 Interceptor, and a 2001 Honda CB600FS Hornet, I have subscribed to your channel, Absolutely Brilliant Chap's God bless America 🇺🇸 Cheers Paul 👏

[@REKLESSWOLVES1]

This is the first time ive ever spent a whole day sat in front of the computer watching an entire series of build videos back to back, Todd, you sir are a Legend, this series part 1 - 13 has been one of the most informative and entertaining series` i have ever watched, for someone like me who has some mechanical knowledge `self taught` i know that if i ever had the coin to afford one of these engines to rebuild in the future your series is more comprehensive and goes into far greater detail than the Haynes Bible, it was like being in the garage with your Dad or Grandad, loving every second mate, well done and thank you so much for a fantastic tear down and rebuild.

[@GordonjSmith1]

This was an outstanding series of videos. 30 years ago I wanted to refurbish my BSA Bantam 175. I tried and ultimately 'failed', had I watched this, I would have 'dodged' every error I made. My wife suggested that my desire to rebuild a British bike was an 'age ' thing, I told her that it was 'unfinished business'. There will be a bike on my yard, and there will be a 'joyful me' driving it down the road to my 'piece of land' where I can pop a can of beer with my boots warming on the coals of a fire while the sun goes down. Simply wonderful skill on show, and very carefully scripted, what a great vlog!

[@hog1100]

Hi from Croatia to Lowbrow customs crew & Todd. I download all 13 series and that will be my Bible while working on my 1979 T140E. I whish you all the best!!!

[@JPHOT100]

Just started the disassembly and rebuild of my ‘72 T120RV. This series is the most informative and useful content I’ve ever seen on KZbin. It’s so refreshing to watch someone who actually knows what they’re talking about. Thank you from the U.K.

[@mconfluence]

I just finished watching 650 series engine rebuild. I really enjoyed it.

[@Dyna3f604]

Absolutely fantastic video Todd is a great mechanic his instructions on building a motor are clear and not confusing at all, he enabled me to split my cases and rebuild my 1970 T120R motor from the ground up. Thanks again Todd much appreciated.

[@nathanhoffman4521]

I wish all rebuild videos were as good as this series! I will certainly be keeping an eye out for future videos

[@sooperzero4087]

Thank you very much for going out of your way to help share the knowledge! You're helping keep these old bikes on the road, and helping a new generation of enthusiasts fix their bikes! Cheers from Australia!

[@johnbedsole6090]

Thank you so much I appreciate your expertise and your support I am in the process of building a triumph engine and building another barn find t120 I own a restored t20 mountain cub . I am a retired ase master tech and dedicated classic triumph owner headed to Barber swap meet again this year. Thank you for your engine building videos If I do my rebuild myself I know what I have when I’m done Thanks again

[@marticon9286]

Todd i cant tell you how many times your video has helped me on my T140 rebuild even though your build is a 650. Thanks so much from across the pond in the UK

[@nathansealey6270]

Good man, even Bentley insisted on no torque specs, rather they left it to the mechanic to decide how tight each bolt should be, simply to avoid stripping threads & damaging bolts.

[@steveburke3923]

My personal thanks for your very complete presentation of a Unit Triumph Overhaul. I have owned many Triumphs from TR-6's through Bonnevilles, A TT Special, to Trackmaster equipped hot rods. Love the brand, love learning about them. Love wrenching and riding them. Great job Todd, thanks Mike!.

[@rayl9335]

Thanks Great video series. very helpful to keep my 68 t120 running right. clutch clicking advice spot on!

[@Nightsoil626]

Bit late to the party,but during this lockdown in the UK have loved watching this series,have a 1970 T120 so learned a lot of stuff from your video's, many thanks

[@christophersmith7714]

Todd you are a legend! You Lowbrow guys are the best! I have watched every one of these videos, most multiple times. I couldn't have rebuilt my engine as well without them. People will still be watching them for years to come! Cheers from UK! Chris

[@dukecammy]

These are the best you tube videos ever!!! If everything goes well, next weekend the old 72 650 will be alive and running. Thanks for all the expert help and a great website to get the parts i need..

[@JPHOT100]

Hello from the U.K. I’m about to begin restoration of a 1973 T120RV 650 Bonneville and this series is absolutely amazing. Thank you..!

[@MichaelMarsden-yh9gi]

this guy is on top of his game, i could watch him all night 🤪

[@frankalvine7310]

Todd enjoyed your series. Wish Lowbrow carried more parts for pre unit. Thanks FGA

[@emondt01]

Todd, I scanned the comments and didn’t see it mentioned. If you’re still looking for a source for the thin washers you mentioned that you can’t find, look at half thickness aircraft washers. You might find what you’re looking for.

[@jimsilver9835]

Can only say fantastic, thank you, and I have things to do!

[@elazarcohen9906]

Thanks Todd! I learned so much from the videos and successfully applied in my 62 triumph T100S. Don't know how I could do it without you 🙏🏽

[@christophersmith7714]

Loved this series. Did you ever do the vid of firing it up? I'd love to watch that. Cheers from UK

[@Dyna3f604]

Fantastic video and a great mechanic

[@vamp507]

Many Thanks Todd, great series helped me out immensely. Nice to see these old Triumph's still going. Keep up the good work! Best Regards from Mike UK.

[@tiedyedkarma]

Thanks so much Todd! This was a great series!

[@bobirwin1028]

Really enjoyed this series. When are you going to show the engine that we watched you rebuild, running down the road? Any chance of you doing a series that compares and contrasts a Triumph 650 with a BSA 650 Lightning? I always preferred the "Watermellon engine". Is there any advantage to the two covers on the right side of the Bonneville?

[@pauliebots]

I watch ALL of these youtube vids and DVDs. You are one of the best.

[@UK00890]

Great stuff, helped me lots on both of my Triumphs. Thank you Tod and Mikey.

[@A10WUK]

Fantastic Series 👍

[@adriangodley]

Amazing sequence of videos Todd. I was on the fence as to whether I should tackle my engine rebuild or farm it out. These videos have given me the info and confidence to have a crack myself. Thanks for putting in your time to share your knowledge Adrian UK

[@gchardy]

‘It’s Miller Time motherfuckers’ says Todd exiting stage right on the out takes😂! Thanks Todd for your 13 part series of patience putting this together. I recognize this as a valuable apprenticeship mentoring series. I have a couple rebuilds awaiting me and your efforts will be my GoTo for knowledge and Low Brow for parts. Cheers. 🤙.

[@billwyatt2449]

I am in process of restoring my first engine and this series has been a true gift. Now when are you going to do videos on the front end and the frame? Thanks much and as my project moves forward Lowbrow Customs will get my business for sure.

[@danilamanila5050]

Just completed watching all 13 episodes Great appreciation to you guys and especially to you Todd Great work, lots of useful information!! Keep rockin’

[@UK00890]

I've avidly been watching these again, great job Todd, (and Mike) thanks for doing it.

[@chrisosullivan2393]

Thanks very much for the in depth guide even over in the uk it is watched thanks again chris

[@austintedrow492]

Thank you Todd and everyone at Lowbrow. This video series was awesome. Can't wait to see more killer content.

[@kevint8128]

Thanks Todd, really enjoyed watching the series. I just need to buy a big barbecue to get the bearing race out and a reamer tool for the camshaft bushes. I'm a bit behind you, just got my cases back from the vapour blaster. I'm looking forward to the video you promised on camshaft bushes, mine have quite a bit of up and down movement.

[@jezdye3615]

Thanks very much for showing this. I really appreciate it. Seen every part! Best wishes from England...

[@brentpeyton4304]

Hello from newfoundland,you are good man, very valuable to the scooter community .Thank you, I have the 650 rebuild and the big twin video, yours is the best, detail is so important, you are top instructor.

[@JamesCouch777]

Thank you for putting this together.👍

[@jaydowney3661]

Todd, I very much appreciate you. You’ve helped me out a ton.

[@shedbuiltmoto]

So Awesome! What a great series. Thank you so much. Can't wait to hear her fire up! Excellent Work!

[@basherbish1]

Hi loved the engine biuld series I learnt a lot from it, I would love the engine biuld book but I'm in the uk...thanks for a great detailed series.👍

[@Hollenfeuer87]

Absolutely fantastic content. Great editing, brilliant videography switching between tripod and handheld shots for closer detail and excellent audio quality from the lapel mic. Really good job guys, Todd’s wealth of knowledge and experience is worth his weight in gold. Subscribed and looking forward to some more great content! Woooh!! 🤙🏻

[@scottsmith3190]

Awesome series, Todd! Enjoyed it. How about doing a 1964 T100SC engine next! :)

[@robertbusack2100]

Wow !!! This brings back the old days Very good info video !!! Years ago I got hit buy the Triumph bug. Mostly 500s a couple 650/750s and a 70 Trident that could FLY by My brothers xlch It still pisses him off to this day.I sold them all years ago but He still has his sporty LOL thanks for the memories. take care,bob

[@rickconstant6106]

A small point about torque wrenches: to achieve the correct torque, the wrench must click while it is moving. If you stop and the wrench clicks as soon as you try to tighten it further, it may not have achieved the preset torque, because it has to overcome the inertia before it can move the bolt. If this happens, you should back it off slightly and retighten in one smooth movement until it clicks.

[@tonyhicks222]

Well done Todd! A very informative series of videos for a T120R owner, especially the revised placement of the Thackeray springs in the rocker boxes. News to me. Just one thing..... Is the motor running points? If not forget my request of showing how to time the ignition with 6CA points. If you're doing any more, would you consider one on cam timing using the lift @ TDC method? The std dots and dashes work well for a stock cam, but an aftermarket cam, or for owners of triples, this would be something that I can't find on the internet and you are just the guy to take up the challenge. Look forward to any more Triumph related vids.

[@Kevin-cy9cv]

Still keep referring to the great videos, thanks Todd

[@davidplumb8420]

What a great series well worth watching.Good job guys.

[@leechamberlain1273]

look forwar to all your videos , well worth the wait , cheers Paul form UK

[@johnrich4504]

Awesome. Very educational….

[@soldtobediers]

59:58 Obligements Todd; Especially for the ''Severe Honesty.'' -DU69160

[@bikebuilder8567]

You are the man on those British bikes'!!

[@2laneblacktop943]

Great series thanks guys !

[@994206]

That is not quite ready for the road, Todd. A Part 14 would finish it off nicely. What oils to use, quantities & where to put them. Which plugs & bolts need undoing, etc etc. That would certainly help me, a recent new owner of a Morgo 750 which has only done 500 miles & needs it’s first service.

[@994206]

Todd, can you please do a part 14. I have drained all the oil from the oil tank. There was a small amount of oil in the sump. It looks to me like this needs to be filled separately. There is a bolt at the back between the cylinders, is this the filler hole?

[@mygoldwinglifestyle9353]

Awesome and very informative series. Thank you.

[@sjoerdgodtartprod8579]

Thanks very much Todd for this really very helpfull video's.

[@musictwins6882]

Thanks Todd loved the videos!

[@derekcollins1972]

Great video as always

[@andrewbull3537]

Cheers todd ,excellent series of videos!!!,keep it up mate!! See you later mate

[@Ebby1600]

Excellent series. Is it available on CD/DVD? Also you mentioned person who does the head overhauls. Please share that information. Finally for the one bike I’m doing is there a place that rents some of the specialty tools used in this series?

[@shawnthompson3001]

Thanks!

[@lowbrowcustoms]

No problem! Thanks for the love!

[@begarlis]

Thank you, nice series

[@stevethompson386]

Brilliant

[@bigsparky8888]

MY 1st MOTORCYCLE WAS A '59 650 W/Single Carb...Lucas Mag...only problem was 1 of the pickups would crack...(I never took the time to find out why)...I took it to Arkansas to get my Dad's 55 Chevy 150 Handyman Wagon...1 Visor, no ashtray...He paid $1,600.00 Brand new & drove it home...Well my 650 left the Trailer I shared with a co worker...chain cut and fence...all I saw was tracks going through the weeds in lot next door...BYE BYE...I LEFT FOR HOME(Calif) and got on with life...(Wah...that Trump ran very well...Bates pipes and Bates adjuster caps w/Bates oil cooler...Custom Flame Paint on tank...it was a looker and my Sissy ("Tooty Scraps") Thought it was a Harley...she was 15 then in High School...She told me all the girls thought I was the coolest...(🙂🙃😉👍🇺🇲💪)

[@davidsaunby5208]

I wish you would show how to install the engine into the frame

[@MrTwcamp]

How about doing a video of how to prime a new engine after rebuild

[@billturner2633]

Brilliant mate thanks

[@gregbailey3710]

Awesome, Thanks

[@michaelwaggett8509]

Hi Todd, really enjoyed this series, but have a question noticed you do not use any gasket sealant on pushrod tubes and rocker box’s ?

[@rustyjunk9008]

Motivating!!

[@tomsaathoff8333]

PLEASE make these available on dvd

[@vorhese]

My only question is going right to final torque? Snug everything, then slowly bring it up, a few cycles of tightening.

[@hankhawks5636]

Now, how about making a video on how to mount a 71 or newer oif conical or disk brake front end on a 70 or earlier frame like the one in this video has. 10:37

[@jacktatum5945]

Hi Todd, Thank you for all your support grate , can you tell me is there a easier way getting the crankcase breather hose on the bottom of 67 Triumph T120 650 and motor in frame, is there a tool or something ? please lit me know Jack

[@sidforbrains6552]

Todd, what do you recommend for a break in procedure?

[@naturalforlife6741]

I think I have the wrong kicker cover on mine. It's1971 unit but there isn't any where to put any gear lube. Mine doesn't have any caps at all. I think you can put the gear lube in the hole where the clutch cable connects. A hole is a hole.

[@YellowroadsterJ200]

Excellent thank you. Just one thing, as it is a wet clutch, is there a need to lubricate the plates at assembly or is it okay assembling dry.

[@GrahamPWhite]

Hi Todd, do you have any oil in the engine at this stage of the operation?

[@luismoreno6659]

después de 13 videos!!!!.....Arrancó??

[@brentpeyton4304]

Good Man.

[@christophersmith7714]

I have used stainless steel head bolts so I have to use copperslip on them. So how much do I reduce the torque settings to allow for copperslip? Cheers.

[@SanghunJung93]

this is why hard jobs record video and works... both two......

[@philipbraid2948]

Hi Todd does the clutch run wet or dry ? Regards Philip

[@lobospero]

Very goog, ped. Malvinas (falklans) are Argentina´s .

[@paulredline1736]

Hey Todd, I have a 76 Bonniville. Any differences?

[@roninkannushi8020]

Does the nut, under the right-side exhaust cap need a washer. Or can I not see washer under the nut, right-side exhaust cap?

[@jonsoons]

The head bolts have a Whitworth hex head but they are cycle thread which is not Whitworth.
