Spark Plug & Crankcase Breather, Honda CB125F

[@danocholi]

Thank you, this is what I needed to know, very useful cb125f channel, best service advice.

[@briforks7681]

A lot of people would be lost or forced to pay dealer prices for every job without helpful videos like these.Thanks for not putting music over it and giving a thorough explanation.

[@richardshephard]

Thanks! People are divided on the music hey? I guess we just don't want it getting in the way of the explanation.

@@richardshephard Please can you change your bike to the new Ninja 500? And do all the oil change service everything.

[@richardshephard]

@@osmanh9394 No problem!

As a fellow cb125f owner you videos helps build my confidence is servicing my bike. Checking the compression with your finger was great. Love from Australia.

[@richardshephard]

That's great, thanks for watching. Obviously don't do it if the engine is hot!

[@salvadorag5586]

As owner of a honda cb 125F I thank you for all your videos. Your explanations are clear and help a lot to make a proper maintenance of the bike.

[@richardshephard]

Thanks for watching. It's a pleasure :-) More riding videos soon I think.

[@GoodDogBonny]

Great Channel, I'm planning on trading down to a CB125F, and this is a great library of simple servicing, its very useful no matter how long you have been riding. Love the riding videos, too. Thanks, Richard.

[@tsiupbmt2822]

Another excellent video Richard, keep them coming please! Thanks for telling us the Sparklug model number!

[@florme6494]

Thank you Richard, it looks like the breather clamp didn’t go in far enough. Going off the previous indents. Thought I should mention it just in case.

[@richardshephard]

Thanks! I'll take a look.

[@alex20041051]

again another very helpful video! thank you very much!

[@NicksBikes]

I really need to clean that breather plug. It's one of those things that's easily overlooked. Come to think of it, I should really replace the spark plug soon, too.

[@richardshephard]

I often think when people take the car in for "a service", are they really getting all these little bits that are specific to each vehicle.

[@NicksBikes]

@richardshephard I once had a mechanic leave an oil filter wrench attached to the oil filter on my car, then denied that it was his. The look on his face when I smiled and walked off with it was priceless!

[@iantobanter9546]

Ych a fi! Gloves recommended when dealing with gunky stuff. My old CB550 just needed the end of the tube (which used to exit alongside the sump) squeezing and dripping the gunge to the ground. I hadn't bothered with this on my 2009 CBF, so thanks for the reminder, I 'll have a shufti tomorrow.

[@richardshephard]

It was more gross than I remember from the last time. Thanks for teaching me "Ych a fi", I'll try and use that!

[@fabg75013]

Comme d'habitude, une vidéo bien utile pour nos cb

[@14923]

Thank you, very helpful.

[@stephenmundane]

Indeed -- thanks again Richard.

[@mateu7942]

Muy buenos videos, gracias por hacer facil el mantenimiento. Un saludo desde las Islas Baleares!!!!!

[@richardshephard]

Thanks for watching. I bet the riding is good there!

[@StevenWilson-n1d]

Hi Richard Thanks for your video,how many miles has your covered now?

[@richardshephard]

About 8,800 I think. It's been absolutely great, no problems at all.

[@edenhunter9904]

Nice work Richard. How about a quick Look at adjusting the suspension?

[@richardshephard]

Thanks that's a good idea. I didn't discover the preload setting at first, and it helped a lot with heavier luggage. It's on the list!

[@tonystone3397]

Thank you

[@stephenmundane]

You could treat yourself (and the bike) to an Iridium plug -- NGK CR-8 EIX CR8EIX. Will likely last forever...

[@kenwarren5129]

Though your plug isn’t really recessed, there’s a school of thought that says you blast the spark plug area with compressed air ( you can buy it in aerosol cans ) before you remove the spark plug. It’s in case there’s any dirt that might fall into the cylinder when you remove the plug.

[@richardshephard]

Yes, very good advice. Thank you I forgot. Don't want any dirt getting in the cylinder.

[@heattwork4344]

Wait... You have a jazz? I guess we're same because i own one from 2006 and im going to buy a CB next year

[@richardshephard]

It's a great car for the rear seats. Bit of a problem with the paint peeling on the 2008 model though. Sad face.

[@paulcowen1976]

How about a video of your cleaning routine?

[@richardshephard]

Good idea. Cleaning isn't exactly 'routine' at the moment unfortunately, but I'll add it to the list!

[@dipeshverma9496]

Sir what's the purpose of the crankcase breather

[@richardshephard]

The crankcase breather hose vents the gases that build up inside the crankcase during engine operation. As the engine runs, combustion gases can leak past the piston rings and enter the crankcase, creating pressure and carrying oil vapors. This pressure could damage seals or reduce efficiency. The breather hose sends the gas back into the air intake to be burned again, reducing emissions and maintaining a slight vacuum in the crankcase, which helps improve efficiency and reduces oil leaks.
