I’ve just bought a 1972 CB175…it’s actually an American import…an absolutely lovely bike and your videos have been an absolute godsend with a plethora of instructions and guidelines…thank you 🙏🏼
Beautiful job... I wish you had been around in 1981.... I bought a pristine CB 200T in June - 1981. It had 6200 miles on it, was my only transportation for 2 years..all through Jr college. I was the mechanic , and I did what I could with a clymer manual and little knowledge. I replaced tires, brake cable, speedometer cble, tach cable, tires , on and on and on.... I was also a total maniac and very stupid and ran it at 9-10,000 rpm up through the gears, a lot. I did change the oil every 1500-2000 miles with Castrol GTX , but I never did understand how that oil filter worked. So I never cleaned it.... ever. At 28,000 miles one of the connecting rod bearings gave out and started knocking so I got a wrecking yard motor ( they were around back then ) . I put that motor in, and ran it hard as ever till around 40,000 miles , I burnt a hole in one of the pistons. Probably did not have it timed correctly... I was able to pull the top end apart, hone the cylinders , put new pistons and rings on it, and it ran fine - ( hard as ever ). Then, not long after, I got it stuck between gears and I could not get out out / un stuck...so swapped transmission parts out of my first motor. The bike ran fine till 60,000 miles when another connecting rod bearing out and I swapped it with a third motor. I ran it another 2-3,000 miles and bought my first 4 wheel vehicle and sold the bike not long after. My point to this whole story is I think it possible that had I cleaned the oil filter like you did here, and perhaps only revved it to 7-8000 rpm ... it may have never destroyed it's rod bearing s like it did. I can tell you, I miss that little bike to this day, and Honda built a hell of a motorcycle. I abused that CB 200 harder I think for more miles than probably anyone in history. Thanks for these vids.. It is very cool to see people enthused about these classics all these years later...
Great video. I enjoy all you vids about the CB/SL 175. Very informative. I have an 1970 SL 175 it only has 670 miles on it. The bike was my Dads and I just got it running after being parked in 1971.
A video on hard/rough shifting would be dope. Going over the shifter drum, shift fork wear and transmission gear dog wear and how that affects the smoothness or shifting.
Thats great! We'll be trying to start to do them more on the video where it can really help when you are doing the repair and watching at the same time.
Perfect! Over here in the mid to late 80s you could pick up any of the smaller Honda twins for very little money and I broke and rebuilt many of them. I have seen that centrifugal filter completely rammed with crud and alloy particles, which usually went with a bu99ered top end and eventually blown big end bearings. You had to chip the crud out with a screwdriver...... This was especially common on CB200s and CJ 250/360s and G5s, none of which have the access port as seen on your CB175. But do changes and cleanings as you show and you can put over 50k miles on a motor with no issues. Pleasure to watch this vid.
Grease on the gasket can you explain the reasoning? Also is there a way to repair or replace a cracked the over flow tubes on the carb bowl? Love your videos
I have a 1974 cb200. The slinger cap is m6-1.00 and the internal threads are a little smaller, but when I tried an m5-0.80, they missed the threads completely because they were too small, is it possible that there was a little bit of deviation here or do you guys think that the wrong slinger cap was put in?
I'm waiting for the clutch video. My new CL 175 is giving me a headache. It's different than the 350 and the only way I learned how to do that one was from your videos
Hey Nick, reach out to your support and we can help you there! I don't have a clutch video for CB175/CB200 but we've done the adjustment on a few motorcycles here.
@@Common-motor hey thanks so much. I think I've got the clutch taken care of but there are a few other things that I could use some help on. I will reach out to you guys if I need to. Thanks again
If your issue is clutch slip due to wear on the steel plates, then as I recall, you can flip the steel backplate (it's asymmetric) and this allows you to put in an extra steel plate and fibre plate which allows you to get back your clutch function for little money. Over in the UK in Thatcher's Britain, this was quite a common dodge as nobody had the money for genuine Honda parts for bikes you could buy for 20 or 30 quid. If your problem is 'hang-up' in operation, this is due (on high mileage or abused engines) to the steel plates notching the rotor and fibre plates notching the slots in the basket. Removing the rotor and basket and dressing smooth with a millsaw file is a fix. If all is un-worn and undamaged, follow Honda instructions for adjustment and cable routing and all should be well.
I am lost on one of my projects and need some help, I have a 73 CB125S and want change the oil but I don't know if it has an oil filter. If it does, is it like this centrifugal system?
Awesome, they'll probably be staying on! We usually use brake cleaner for tough things you can't remove. When you can easily remove a part we use our Parts Washer which is an awesome thing to have if you're working on old motorcycles!
Is the brake cleaner good for removing those old gaskets? My cylinder base gasket is holding on for dear life. Thinking of trying a wd-40 soak, permatex gasket remover, or the brake cleaner.
Let us know if you find the addition of chapter markers helpful in our repair video! We've decided to include them in the next few videos. If you still have questions about your repair reach out to our support via common-motor.com. Thank you!
I think it would be helpful if you made it clear that these Japanese bikes do not use Phillips screws. You call them Phillips screws at a couple of points in your video. They are JIS screws and you need JIS screwdrivers. JIS screws can handle more torque than Phillips - if you use a JIS screwdriver.
Bought a 1972 CB175. Owner is dead and I don't know what he was running for oil in it. I'm torn between synthetic and mineral oil. I've had good results with synthetic oil in my cars and trucks and would like this bike engine to last as long as possible. It has 16k miles on it now. But back when I was running these Honda Twins years ago we didn't have synthetic oil.
My advice: don't use synthetic or even semi synthetic. These old clutches slip easily with fancy synthetic formulations. and you may get oil leaks from seals that weren't leaking before you put full synthetic in there
I pulled the pipes off of a Scrambler 175 Honda, and never again will I do that. I had to remove 2 of the exhaust studs on the left side, to get both pipes off. One of the 2 pipes is welded to the muffler, and one pipe is attached with a clamp. Both pipes should have had clamps. This bike you are working on must be a road bike and I think removing the exhaust would be much easier on it because each pipe goes back on opposite sides of the bike,,,,,,,,,,,
Hey Mahir, we are not an actual repair shop. We make our videos to help the motorcycle community as well as provide support and how-tos for the specific motorcycles we support and sell parts for. You can definitely message our support over at common-motor.com though if you are needing some help and we will see if we can get you some answers!
Some of the bikes we have messed with have had the threads a bit mangled. It can help to run the tap into the threads to clean them up if you are having a hard time.

Helpful tip, the bolt from your handle bars works perfectly for getting that cover off as well. That way you never have to find the bolt.
Dude, this is great. I just bought a '74 CB 200. this site is perfect!

This channel and your website are amazing, thank you!
Love your videos and looking forwarding to seeing more CL175 vids. The chapter markers are extremely helpful as well.

What spray cleaner did you use to clean out the filter?

Does this cover the CD175 engine also? Thanks
Great video! Does the cb160 have the same filter setup?
I am lost on one of my projects and need some help, I have a 73 CB125S and want change the oil but I don't know if it has an oil filter. If it does, is it like this centrifugal system?
What product do you use to clean? Also, the chapter additions are great

oil filter cap is stuck on. bigger threads are stripped. already tried drilling into cap, fitting wire through and pulling. next step- grind cap off.

They are JIS screws and you need JIS screwdrivers. JIS screws can handle more torque than Phillips - if you use a JIS screwdriver.
Hi brendon. Any idea when shockwaves will ship this spring?
Ditto on this. I have a preorder in for the shockwave.
@@mikek1187 for sure i cant wait to set my ignition timing and than forget about ever doing it again
Hey guys, reach out to our support for our latest shockwave updates. We wish they were already back in stock here ourselves!

Good vid but not to sure you actually installed a oil filter sure didn't look like it🤔 so it's not really a filter just clean the crap from inside?
Hi Brendon, is your service open?
I would like to bring my bike, some works need to be done.

@@Common-motor thank you for information.
maybe you can recommend someone or some shop which work with old bikes.
Anyone else can’t get the M8 bolt threads to catch?
Some of the bikes we have messed with have had the threads a bit mangled. It can help to run the tap into the threads to clean them up if you are having a hard time.
Could be an M8 screw with the wrong thread pitch.
surprised you`re using an oil designed for cars as opposed to motorcycles. Not best practice for any machine running a wet clutch.
