Setting The Cam Chain Adjustment And Valve Adjustment On The Honda CB175/CB200 Family Of Motorcycles

In this video, we go over the proper way to adjust the cam chain and set the valve clearances for the CB175 / CL175 / SL175 / CB200 / CL200 family of motorcycles. Cam chain and valve adjustment are the second and third steps in the regular engine tune-up process; this adjustment must be performed every 1500 miles (2400 km) alongside an oil change and ignition timing. The cam chain should be adjusted prior to the valves to ensure proper camshaft placement for the adjustment. Having the necessary skills and knowledge to service your vintage Honda every 1,500 miles (2,400 km) is key to having a reliable, well-performing daily driver. This is what we consider here at Common Motor Collective essential knowledge required when owning one of these motorcycles.

Great timing! I'm doing the valve adjustment on my '73 CB175 this weekend.

Excellent video! I like the list of parts you'll need at the beginning, as well as CMC links to those parts. Just makes me want to buy more parts and tools from CMC (just did for my CB360!). Angles of the video are great, as well as the zoomed in portions. Thanks for that. I think this is the new benchmark for the DIY.

Glad to see you're carrying parts and doing videos for the smaller Honda Twins! I'm working to get my 72 CL175K6 on the road after being stored for 20+ years.

We love the small twins and are hoping to have all the parts that seem to be missing for them. We currently have quite a few things being made so we can bring all of the CB175, CL175, SL175, CB200 and CL200s back to life

As a Diesel mechanic of 25+ years I always hold onto the adjusting bolt when adjusting valves or a Jacobs brake or any other adjusting bolt that locks with a jamb nut. It's just good policy/ practice to do so. This is critical on old school Cummins diesel and 2 stroke Detroit diesel fuel injectors,as the settings will change just by locking down the jamb nut

@johnwad7468 3 жыл бұрын

I guess you did hold onto adjustment and jamb nut as I continued watching your video. My bad. But good video overall.

@@Common-motor I'm in middle of a restore on a 1979 cm 200twinstar. It's for my Boss's son in law. A engine off frame going over. Bike was neglected. I completely repainted frame,and all painted brackets etc. Worked on rims, pipes, brightener on aluminum engine parts. New tires, battery,new carb,air filter,etc. Never was into one of these engines and cam chain adjustment is in the back,instead of in front. But I know enough about being a mechanic to consult people who know. That's why I clicked on ur video. I plan on replacing points with CDI at some point. Anything to watch for when doing that? Or is it fairly simple,as I suspect? Thanks.

@hiscifi2986 2 жыл бұрын

It would be nice to know how many thou there are per revolution of the adjuster, then you would be able to turn it a ball park amount. I used to work on Fork Lift Trucks, that had a ball valve on the top of the lift cylinder, to let trapped air out. It was a 3/8 ball pressed into place with an alan screw. Then the alan screw was locked with a nut. Unfortunately when you tightened the nut it slackened the alan screw and let oil out. The only solution was to do the screw up really tight, and leave the nut moderately slack. btw.. I think my CB250 is the same construction.

Can you make a valve and timing adjustment for a Honda cb100?

@matthewcmeagher Жыл бұрын

Can you feel in the adjuster nut when you’ve gone far enough to take the slack in the cam chain. I’m having a hard time understanding what I’m to expect when I go for the adjustment

I'm trying to gather enough info to do this on my newly acquired 1963 Superhawk CB77 305. Do you happen to know if it is a 360 or 180 crankshaft? Thank you and great channel!!

Hey Brenden, Thanks for this Video. I bought a cb200 an wanted to so this procedure. My Problem ist that the screw for the Cam Chain was loose. I cant screw it back on. I think il have to remove the cilinder head and have a look on the inside. What do you think? Thanks, Jonny

@juice2157 3 жыл бұрын

Thanks for the clear and concise lesson. Before I go for it, will this info apply to my 69 cl125a scrambler? Thanks for your response.

@Common-motor 3 жыл бұрын

Its going to be very similar, there will be differences because its only one cylinder and you of course might have different values. I'd check the service manual for the slight differences but the concept will be the same.

@matthewesselstrom3792 Жыл бұрын

Can these steps be done one at a time? Like if I were to do the cam chain adjustment and valve adjustment today, and the ignition timing next week, while driving the bike in between

@richieortiz5 2 жыл бұрын

What if you set the timing on and it’s slightly advanced on one revolution then slightly behind on the next?

@Flofeat. Жыл бұрын

I understand that I need to make this adjustment and 360 rotation on left and right cylinder separately? Left cylinder on T1 and right cylinder on T2? Or am I wrong?

@crazylikeafox7341 3 жыл бұрын

I made this adjustment and obviously did something wrong. Lost compression in the left cylinder while riding. Opened tappet cover to find valve set screw and jam nut came out of rocker arm. Found set screw pinned under valve spring and was able to retrieve it. Problem is I can't locate the jam nut. Removed all tappet covers and fished around with no luck. Where could it have gone? There is no real way for it to drop down into the motor is there?

I miss the valves on CB750

@noahtimmerman1819 3 жыл бұрын

Hey, This is about a Honda CB125 k5 from 1972, but the motor has the same working mechanism. Having replaced pistons, piston rings, valves (lapped),... everything assembled as specified in the manual: "T" mark on the crankshaft alligned with the dowel of camshaft pointing upwards. Valve tapping clearance is set at 0,05mm. Now, at TDC, my exhaust valves slightly touch the pistons. However I can manually rotate the crank shaft with very small tapping/resistance at TDC. Is this a problem or can I proceed the assembly and set ignition? Thanks in advance! Noah

@Common-motor 3 жыл бұрын

Hey Noah, your valves should definitely not touch the piston. Its a recipe for it to bend the moment you start it up. Had a similar thing happen on my CL450 and the camshaft had become misaligned with the crankshaft. I would double and triple check the alignment of those pieces according to the manual as a start because that shouldn't happen.

Would this cover cb100?

@Common-motor 3 жыл бұрын

I'm not incredibly familiar with the CB100, its kind of a rare bike but the concept should be the same, I'd check the honda service manual for any different values or specifics with engine placement.
