As part of the Honda CB350 series of motorcycle (CB350 / CL350 Scrambler / SL350) routine tune-up maintenance, the engine valve clearance, as well as the slack in the cam chain, must be adjusted. This adjustment needs to happen every 1500 miles (2400 Kilometers), along with an oil change and setting the ignition timing. In this video we explain the reference marks on the rotor, show the adjustment process for the cam chain and perform the valve or rocker arm clearance adjustment on this CB350 engine. We also introduce what we call the "overshoot method" of setting valves by using a feeler gauge that is 0.001" larger than the factory specifications to ensure ample clearance (better to be a tad loose than tight). The same process is done for all 4 engine valves.

I'd like to thank CMC for doing the series on the old Hondas. You are really helping the community keep these old bikes going!
Really appreciate the videos. Been a long time/current customer and love what you. It's also a bonus that J. Mascis is teaching me how to wrench on my bike!
Brendan just want to say how 'proud' or whatever that you turned your passion and ours of these bikes into a business and are living these bikes everyday.
CMC is a movement and a 'lifestyle brand' haha.
Did you like your own comment?

@@californiamonster8877 I’m proud of you, or whatever
Overshoot method Honda doesn’t use that they use go no-go method that means you put your .002 gauge in there and set your valve to check it you take the .003 gauge and if it goes in it’s not .002 you don’t want to .003 to go in. What your achieving here is a perfect ..002 setting and with Hondas they want a perfect valve adjustment or they’re not going to run as good as they can I went to Honda school and that’s where I got the information used it for years it’s never failed me with Hondas there’s no such thing as a tight or loose valve setting or point setting for that matter.
That being said the rest of the information was really good.
Thanks for the effort, easy to understand and just so darn enjoyable.
Nothing is more enjoyable than Brenden talking motorcycle.
Heck of a lot easier to determine compression stroke by just rotating engine correct direction and watching intake rocker. As it begins to come up (close) then continuing rotating until the LT is reached. (left cylinder, left intake) Repeat for right side using T mark. Especially if your old engine has valves adjusted incorrectly and you don't have any compression!!!!
Thanks for sharing the correct procedure on adjusting the cam chain on these engines. Lots of people adjust it by following the incorrect procedure that can be foud in the Honda and Haynes workshop manuals. Afterwards they try to tell you that these engines are supposed to sound like a rumba shaker.
Glad to help!
Great video guys! Thanks so much for putting out such informative and well done content!
Thank you!
Great videos! Thank you so much. Great explanation, good videography, excellent presentation
Thank you sir. Great, insightful info.
Thanks for doing this, guys.
Glad to help!
The video is very helpful. Question, I put the engine together and on the left side the index marks are at 12 and are tight on the left side in the LT position. Do I have to remove the shafts and place the index mark at 4 and 7? THX
How many miles can I expect on a 350 before the cam chain and tensioner needs replaced if maintained properly. And if it goes bad will it destroy the engine? 🤔
I have a 68 CL350 and my cam chain adjuster is not like what you are working on so i looked up in the manual you have on line and it says it's a hydraulic adjuster. When did that change could you explain this.
VERY Informative infoormation...
Thanks for the video! Regarding your overshoot method when adjusting the valves. If I make the gap slightly to large to the point the valves make a slight clicking sound when the motorcycle is running, will that damage them?? Thanks for the great content!
"Lose valves make noise tight valves break parts" 😂
loving these videos!
We're loving that you're loving them!
Just opened mine and it looks like the right side intake valve adjustment screw was 180 out. It’s been run like that. What damage can that cause?
great channel, thank you.
With the overshoot method, would you expect the procedure to generate some valve noise or would you expect it to be silent'ish after?
"Slappy valves are happy valves"
HAHA we really don't experience any crazy noise or much at all. I'd say silent'ish.
Thank you. Great channel. So LT mark for left cylinder and T for right cylinder ? Thank you.
Love it I have same bike same color
Saw a video on how to do something similar without having to take the carbs off
Definitely not necessary to remove the carbs! Gives you a bit more space but also this bike was a project by at the time of filming this video.
My 1970 cl350 was running perfect but i started to here a rattle noise and it was due for the adjustment mileage wise. Did exactly what video said and now i can't even get it to start. Please help!
Well done but next time do what Honda says to do, if it says .002 set it Exactly at .002. Your welcome !
Maestro!.
Great vids
Thank you!
Is that the same procedure for a 1970 CB175 twin as well?
The valves can vary so check the manual to be sure but the feeler gauge method will work no problem.
is the pin on the camshaft that holds the advance unit in place,is that supposed to be top or bottom? By top i mean is the pin supposed to be at 12 o clock position?
In relation to what??? It really is not something you should be referencing for any engine position. All you need to pay attention to is the rotor.
@@Common-motor I mean should it be in that position at TDC LT on the compression stroke?
??? Never looked at its position I reference to tdc @the LT mark. Always used the thumb over the plug hole technique to figure out compression stroke.
Take the back left valve cover off and watch for the valve to go down then come back up. right then u know u are on compression

não gostei vc não mostrou a regulagem de valvula do segundo cilindro ok
