Fantastic bush bike bell. Great bikes, so easy to work on. Cost little to buy, maintain, rego and insure. Best in class on petrol too. Nice and light to take out of the garage. Centre stand to make it easy to store and for maintenance. The only thing that could be better for me is the top end speed, and dreading when you see a big long hill. That being said, I know that’s not what the bike is for. Thanks for running us through this.
Tengo ese modelo de moto. Gracias por explicar el ajuste de válvulas. Esperamos más vídeos explicando las reparaciones básicas y no tan básicas de esta moto.
Yes it is correct. Is another RUclips video same year CBF, and there show manufacturer pdf photo with same numbers: in-0.08, out-0.2. I find about the same gaps when open my 2022 cbf valve cover. Btw, thanks for very informative video!
I am not sure about that as the Haynes manual for the older versions of this bike states 0.12mm exhaust (+ or - 0.02mm) and 0.08mm inlet (+ or - 0.02mm) which is where I set mine 4 months ago and haven't had any issues. It is a 2022 Honda CB 125 F I own. When I reset the valve tappets recently the exhaust had closed slightly but was still within spec. Obviously need clarification on the clearances but to me 0.2mm seems a bit of a large gap!
@@nickwinn7812 Are you sure the exhaust is 0.2mm as the older CB125F is 0.12mm plus or minus 0.02mm. Inlet is as you state 0.08 mm plus or minus 0.02mm?
@@DavidPritchard-i7x I adjusted mine today. It has 7k km and the exhaust was a bit larger than 0.2 so I think it is the correct. Maybe it's different from the older version because it run leaner and there is more temperature in the engine.
@@davidbiro7681 I think I will have to check it out further, mine is set to 0.12mm and has done 21,000 miles now with no issues. When the bike was new in 2022, it developed a head gasket leak which I assume was a manufacturing fault. The Honda dealer did the repair, replaced the gaskets, both the head gasket and the one at the bottom of the cylinder. So they would have had to do the clearances for that. Honda did the servicing after that for the 4000 mile service and the 8000 mile service, when I checked the clearance at 12000 miles it was closer to 0.1 mm so I set it at .12 mm. I have been unable to find the service data for the 2021 (onwards) CB 125 F. But the standard setting for all the older models was inlet 0.08 mm and exhaust 0.12 mm. I can accept that I may be wrong but 0.2 sounds quite wide.
interesting. I've just been working on an old 1980s honda cg125 on behalf of a friend, and the valve tolerances there were 0.08mm on both intake and exhaust. i wonder why the exhaust was so much larger on your bike? perhaps running lean for emissions control has the valve stem getting hotter and therefore expanding more?
Great video as always. I noticed a small amount of oil near the large semi circle rubber seal on the left side of the cover as you push it in when the engine is warm a little moist line appears ???
On your bike? I guess that's a vulnerable area - the big rubber seal could change shape and allow a drop of oil out. It's not under much pressure, just protects the rocker and stops oil squirting out, so as long as you're not losing a lot of oil not a big worry. Easy enough to replace that seal: www.bike-parts-honda.com/honda-motorcycle/125-MOTO/CBF/2022/CBF125MM/Engine/CYLINDER-HEAD-COVER/103400/E_01/1/45503
@@brucemichailidis8951 Excellent, nice one. That's definitely on my list - the chain/sprocket is starting to wear after 7k miles, so when the time comes I'll definitely film it.
I thought that this motorcycle was not suitable for long distances because it was air-cooled. How many hours can you travel continuously with this motorcycle for a healthy ride?
It depends how fast you're going, or how hard the engine's working. I would not recommend going at the bike's top speed for long. But at 50mph I'm pretty sure it could go all day. It did, in fact!
Thanks! I haven’t figured out how to turn the crank with a socket on this bike so I haven’t seen the flywheel at all. Turning the back wheel works ok so I just used that.
So, basically, my Mrs could do it then? We'll, she normally strips me down to get access to my 2x nuts, so I'll buy one of these bikes tomorrow, I think. That way, whilst she's stripping it all down to get access to those 2x nuts, she can change the oil and air filters as well 👍 Nice cheap motoring that way 👌
I don't think it's adjustable on the modern bike as it's all electronic. I remember turning the distributor on my 1980 fiesta to 'convert' it to unleaded petrol.
He showed the timing marks and explained to put the engine at top dead centre on the compression stroke. Incidentally you can check and adjust the clearance at any position where the cam lobe is pointing away from the rocker arm or in the case of direct overhead cams, the valve itself.

True, all it needs is a more utilitarian look, 17-inch front and back rims for more tyre choices and a bit taller 1st and 2nd gear.
Very clear instructions and complete details thanks
Found this to be a very well made and informative source of information, thankyou
Thanks! My rules for mechanics videos are, no waffle, put the camera on a tripod, and always show the difficult part.
Well done mate, I’m an Englishman down under running the same bike, can now do the valve adjustments myself having watched this video.
Thanks for the great video. Not sure if I have the nerve to try it for myself yet!

Thank you. Just realized mine needed to be done 2000 km ago 😂
thanks for a great vid. really well presented.
Isn't there a shop manual foe these somewhere? Honda still does PDF ones for the bikes.
I can't find one. Please do share if you have!
Sir this valve clearance is company recomanded ? Show the book of valve clearance plz
Does anybody know how to find the idle adjustment screw on this bike? What needs to be removed to see it?
input 0.20, output 0.08? I understood correctly, I can’t find information from the manufacturer anywhere. Thank you

Other way round! inlet 0.08 exhaust 0.2. The exhaust clearance is always greater than the inlet because it gets much hotter.

In India this bike is called sp125
At how much km we should set it
Every 6,000 km (4000 miles)

That's a possible theory! I haven't got the experience of other models I'm afraid.
La galga que sale en la imagen para la válvula de escape es la 0,08 mm y no se corresponde con el rótulo
I think the bottom number is the size in mm, and that says 0.203. I hope I've got that right!

Thank you so so much Richard your a champion really appreciate your time and effort.
Hey Richard new gasket worked a treat. Any chance of a sprocket chain combo ?
@@brucemichailidis8951 Excellent, nice one. That's definitely on my list - the chain/sprocket is starting to wear after 7k miles, so when the time comes I'll definitely film it.
Thanks Richard look forward to it cheers mate
Do you have a source for the valve clearances?
Someone on FB phoned up Blackpool Honda. Best we could do.
Very good

Hey there, nice one
Why you didn't show the T mark on the flywheel and the groove on the engine
👍

What's a matter not got a spanner for tappet.

You didn't show the most important part of valve clearance. Timing
I don't think it's adjustable on the modern bike as it's all electronic. I remember turning the distributor on my 1980 fiesta to 'convert' it to unleaded petrol.
he showed to put the bike top dead center
