Watching from Philippines!. Excited of your project.. keep it up!
Thanks & hi Philippines
Great video, loved the panning shots and the way you edited it.
Thanks Tony
Great vid👍 watching the engine get reassembled is awesome
Thanks. Glad to see it all back together though.
These videos are so great. Thank you!
Thanks for watching.
You put in quite a bit of work! Looking good so far.
A lot of hours
looking good, coming along nicely. Good luck on the Bike Shed Show, hope it makes the cut. wish I could be there, but other side of the pond, one of these years hopefully
So do I, would be amazing to see it there and for you guys to see it in person.
Well done mate!
Thanks
Nice to see the engine assembly not all build channels do that. Going to sound mean with that 4 into 1 exhaust!
Ive come across some builds not stripping down to the frame either, which on a 40 year old bike I think is important, gotta say with the CX I didn;t bother with stripping the engine only as I had receipts with the bike for new rings etc.
I agree 100% got to make the bike run also have to make it safe to ride!
Love ya builds mate but side note dont tighten the cam carriers like that all need to go down at the same time (per cam) can run the risk of snapping camshaft, I've seen it many times and been unlucky enough to have had it happen to me with a mercedes even bringing them all down at the same time, keep up the good work mate be good to see it built 😁
Love the video making techniques you use. Best of luck with that engines I'll be doing a gs550 before too long but I have to dig into my DOHC cb 700 first
Thank you.
The best!😍
thumbs up
I've been watching your build videos on this a lot and I haven't seen anything about the valves on this bike. Did you end up doing anything to them? Replace or lap or re-grind them?
No lapping needed on these. Had them measured at the shop I had the cylinders honed
Can I ask what did you do with the fork tubes? Did you re-chrome them or did you just buy a new ones?
Great videos 👍🏻😉
Thanks.
They've just been polished up
I'm trying to get into a cb750 but I haven't had a lot of experience with motorcycle work. I'm worried about not being able to do a lot of the stuff I want on the bike. I was also looking at having someone custom make one for me how much does something like that usually cost I hear it can be pricey but i've never got a definitive answer any info helps thanks.
Have a look at the classified section on the bike sheds website. I’d say anything starting from £10,000 would be a good start. Also look at Hookie and Debolex. They sell bikes.
What did you do about the RPM cable insert it the camshaft cable? I am currently working on the same CB 750c due to your videos.
It's still there.
@@forthebold putting the tach cam holder back how do you get ie aligned with the shaft?
Argentina!! Yo
where did you get the new cam holder I thought one of them was cracked.
I buy my Honda spares from David Silver Spares
For The Bold - dreegez I’m building the same bike and I have a broken cam holder L piece and I have been looking for that part for a long time now.
Hi , where did you get the download for the manual . I have tried to find one for Triumph T120 but no luck . cheers on good build
You can sometimes find them on forum threads
Cmsnl.com try this
@@nebepisk Thanks , however its a Triumph T120 (2016) That I am looking for
Paul Martin oh damn, sorry
where did you download that biker build guide??
Any Honda forum can help
Great work
But too much camera movement and hands too close to camera when doing the ratchet
Looking forward to the next vid
......hey that sounds like the intro to Jish's channel...... ; p
Super B!
Thumbs up
New cam chains??
No need, they're all within the tolerances
Please could you put your camera on a tripod ? Thank’s
What’s your tea recipe?
Wet, pretty much it
Like your videos. But this one is tooooo shaky and to many cuts. Impossible to se how you do it. :(
Hi, I rebuilt the engine and now I am having Rev hanging issue, Engine idle in 1300 RPM if I rev more than 4000 RPM getting stuck in 7000 RPM, See the link for reference. ruclips.net/video/f9D2ix0UxUE/видео.html HELP!! Is it a timing problem or anything else?
Have you checked your carbs aren't sticking? vacuum leaks?
Did it say in manual you need to lube cam bolts? If it don't, you are messing you torque..
I always lube for accurate torque. Without lube you don’t get true values.
@@forthebold clearly you don't understand clamping pressure nor metal yielding strength.
@@forthebold I really hope you do try to find information about things you are doing and just not do as someone other has done.. Using lube with threads do not make you get true torque values, it does the opposite.
1st things 1st. Point isn't to get bolt torqued. That is only means to an end. Your priority is to get right clamping pressure on items you are fastening. 2nd you should not apply extra clamping pressure, cos that ads extra force on fastener and you might get it over yielding strength.. that only don't mess up your bolt but also when bolts meet its yielding point they stretch and you will loose your clamping pressure.
Then you need to understand how torque works, what does add torque and what diminishes it. Your torque is sum of your friction on your threads and bolt (and or nut) surface. So if you lower your friction on your threads, you add clamping pressure even tho you apply same amount of torque.
Read more from here: www.researchgate.net/publication/238747201_An_Experimental_Method_for_Measuring_Clamping_Force_in_Bolted_Connections_and_Effect_of_Bolt_Threads_Lubrication_on_its_Value
"Conclusion: It is found that the lubrication of bolt threads provides
higher preload in the joint comparing with dry condition
because of decrease in friction coefficient, and consequently,
decrease in torque coefficient from 0.205 to 0.165, for the dry
and lubricated conditions, respectively. To conclude, applying
torque to the lubricated bolt creates higher preload that is
desirable and safer for design of mechanically fastened joints
connecting main parts of the structures"
Interesting but you do understand that the conclusion you pasted actually advocates and encourages the use of lubrication by saying it's more desirable and safer to add lube?
"To conclude, applying torque to the lubricated bolt creates higher preload that is
DESIRABLE and SAFER for design of mechanically fastened joints connecting main parts of the structures"
@@forthebold Yes, if your main reason is to apply maximum clamping force, which in engine building it isn't. In engine rebuilding your main focus is to apply manufacturers designed clamping force to surface. If you apply too much, you might end up warping parts or exceed bolts yielding force. If you think maximum force would be best idea, why do you use torque gauge? Just tighten them as much as you can.
If you would read whole quotation, you would find "decrease in torque coefficient from 0.205 to 0.165" part interesting. That means, that when you add lube you will produce more clamping force (and force for bolt) with same amount of torque. And if you take your calculator, that means 20% more force with same torque.
This is what I mean, you need to know what you are doing and why.
Subtitulo ¡ESPAÑOL!!! BROTHER
Why he's from a non Spanish speaking country???
Thanks
I AM FROM ARGENTINA COUNTRY!! MESSI
Unwatchable. Annoying music, frenetic camera movement.
If you move your head the same time as the camera does it balances it out.
