Yes I'm happy now not knowing the cause of a a sound which you know isnt normal (especially inside the engine). Can cause anxiety when riding far ahaha

Hey Phil1 Do you still live in Yorkshire? Do you go for ride outs?

Hi everyone thank you all for your help. I adjusted the tappets back to spec.(they was a little bit out). After adjustI started up the bike let it warm up. I still heard the noise, so I decided to have a look at the cam tensioner. The cam tensioner seems to be fine. The chain seems slack and the teeth on the sprocket look worn and you can see a tiny bit of day light thru it. I tightened the tensioner a 1/4 turn and it has tighted up a bit of the slack but I think it will need a new cam chain and cam sprocket. Before After sound So it has stopped the noise but. It's definitely worn. I'm guessing maybe the last ownership ran the oil low and starved the engine of oil and stretched the chain . Anyways that is what the noise was and I know how to fix it now. Thank you all for your help. It has been much appreciated.

Thank you I have ordered a Haynes manual and a feeler gauge. I'll keep you guys updated with the progress and tell you my finds once fixed so this post can help others. I'll check clearance first then. Have a look at the cam chain tensioner 2nd. Thank you for your help

Thank you for listening and trying to help. You ideas and help is appreciated. The noise is definitely internal. Here is a video of the noise from a cold start up until it get warm( which is last 5 seconds of the video) https://youtu.be/IBt2umrYpWQ?si=B81NL4U6QEGMsTb5

I Hi thank you for the response. I bought the bike in December at 8500 miles. It is currently at 10002miles. I will upload a video to youtube and post the link to see what you think. You help is appreciated. The bike does work and runs fine but the noise is worrying. https://youtu.be/dKh8u1T5q74?si=6RkxeiyOrQ6UvNa6 Thank you

Hi I have a Honda cb125f 2017. When cold there is no noise but as soon as it warms up I hear a clicking, clanking sound. I changed the clutch thinking it might be the clutch basket and a worn clutch/ basket but it's not that ( rides better with the new clutch ) . There is oil in the bike never in my ownership ran empty! I am the 3rd owner. Sounds like it is coming from the cylinder head area. Definitely not clutch area as when I put my ear there you can Definitely tell its coming from elsewhere. If someone could please help me figure it out I would appreciate it Thank you. I can upload a video to youtube of the noise if needs be.

Any ride out groups in west Yorkshire?
