Yes it is correct. Is another YouTube 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!

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.

Very clear instructions and complete details thanks

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.

[markmolloy]

thanks for a great vid. really well presented.

Thank you. Just realized mine needed to be done 2000 km ago 😂

[martinarmer]

Thanks for the great video. Not sure if I have the nerve to try it for myself yet!

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 ???

Isn't there a shop manual foe these somewhere? Honda still does PDF ones for the bikes.

Sir this valve clearance is company recomanded ? Show the book of valve clearance plz

[voncheeseburger]

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?

[zhenyabahus]

input 0.20, output 0.08? I understood correctly, I can’t find information from the manufacturer anywhere. Thank you

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

La galga que sale en la imagen para la válvula de escape es la 0, 08 mm y no se corresponde con el rótulo

[DavidPritchard-ix]

Does anybody know how to find the idle adjustment screw on this bike? What needs to be removed to see it?

[NicksBikes]

Do you have a source for the valve clearances?

[seyhmuscakan]

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?

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 👌

You didn't show the most important part of valve clearance. Timing
