Gotta love that sound! It's funny - never thought of it being a sewing machine! They always said that's the sound of the BMWs. Liked this video a long time ago, but didn't thank you. Very well done! (1977 750F2 Super Sport).
Thanks for posting this, I've had trouble adjusting the tensioner in the past and you made it super clear. Coincidentally my 750 is also flake sunrise orange, such a head turner!
Thanks for the video. How often should I do this...and how do I know if my bike needs it? My 75 CB750 runs great, but I don't know when cam chain tensioner was last adjusted. Probably in the last couple thousand miles or so.
Man that was an awesome video. Question, I have a very slight oil leak at the tensioner case and the jug, can I use this procedure to safely remove it and replace that gasket?
Just got a 1977. Lots of work with carbs. etc - but needed to know about the cam chain adj./ top dead center, etc. Who knows when mine has been adj. *** Plus need to get the valves synched as well. My channel: Wildman RG3
my factory manual for my 77 CB750 says, start engine, loosen cam chain tensioner screw, let it adjust automatically and then retighten the screw and locknut.
It makes sense. Essentially these cam chain tensioners are just springs that push out on a chain guide. With the engine running it would be able to adjust to the movement of the sloppiest part of the chain chain and not a stationary position.
How do you how tight to make that screw for the cam chain tensioner. I have excessive ticking on my cb750 and I am unsure if it needs a valve adjustment or to tighten the cam chain tensioner.
Conrad riffle I would measure the tappet clearances first - it's easy. On a cold bike open the tappet covers and measure the clearances when the valves are closed. tap tap tap tap noises are very often tappet clearances that have enlarged so the valves hit closed harder.
I've never heard that, sorry. I was told this is the point where the tension is correct. If you do it again it will be at a different tension. It is set when you do it.

Thank you very much for this vid. I have a 74 same color. Love my bike more that any other bike I own. It’s got soul, spunk and classic style.

Glad to be of help. And yes, that is the best color.
Its the color that makes it hard to keep adjusted!
Thank you so much! Thanks for keeping it simple!
cheers mate. west australia
Totally digging the way you say "centre"

the twin cam 750s you adjust the cam chain tensioner while its running!
I believe number 1 cylinder is on the left while sitting on the bike. Correct?

markman63 Interesting. I’m amazed that it would find the right spot. Is it the DOHC?
It makes sense. Essentially these cam chain tensioners are just springs that push out on a chain guide. With the engine running it would be able to adjust to the movement of the sloppiest part of the chain chain and not a stationary position.
Thanks a lot. How you change your bike electric system to magnet (transistor)???
Would this procedure also work with a honda cb350f? I can't seem to find any information about the cam chain tensioner etc? Nice video man !
Awesome vid thanks
Glad to be useful. Thanks.
For adjusting cam chain tensioner, why you need to bring piston to TDC?.
Puts the slack at the back of the chain
Thanks, I could not find this procedure in my manual
Awesome!
would this apply to my cb250 nighthawk... VERY similar engine... i cant find ANYTHING on youtube for my bike :S
Good video. Looks like the valves need to be tightened up. If they are clicking like that they are over .003".
Good stuff, what kind of wrench is that? looks ideal for the job....
It's a pretty standard 24mm ratchet wrench.I got it on line because it fits my wife's vespa's oil drain plug. It fit here coincidentally.
Great info

Could you please make a valve clearances vid too please for the Honda 750/4; that would be greatly appreciated please.
Thanks that's a great tip.
I was told that after this is done to rotate the engine 180 degrees and do it again. Does that sound right?
I've never heard that, sorry. I was told this is the point where the tension is correct. If you do it again it will be at a different tension. It is set when you do it.
@@jayelwin Yeah, that's what I thought, it's not in the manual.
quick question j, would i have to remove the valve covers in order to adjust the cam chain tensioner?
No only the little valve adjustment ports to see which tappets are loose.
thank you so much J! going to check it out this weekend!
great, thank you!
Glad you liked it.
perfect i was looking for some help with this.
Great!
Thanks!!
Yeah..this totally helped my bike.
Do not turn the engine clockwise!
You should only turn the engine FORWARD which from the right side of the bike happens to be clockwise.
Helped me
Straight and to the point
Thanks
Awesome thanks
