Hi,
I have a 2011 model Honda CBR250. It makes this very loud and weird noise from the engine. It is so loud and weird that I feel embarrassed while riding
I went to Honda ASC here to get that checked and they changed the chain tensioner, both rocker arms and installed shims of the correct size. All went well till 1000-1200 KMs and it again started making that weird sound. I again got that checked by the ASC and they installed new chain tensioner once again. After another 500 KMs, that sound returned. I went to another Honda ASC this time and they checked the sound and informed that timing chain is faulty and they replaced that.
With the new timing chain, the engine got very smooth but that sound again returned after another 1000-1200 KMs. I went to that second ASC again and they were now clueless. They checked the clutch but couldn't find any issue, checked rocker arms again and tried replacing them for testing but no luck. They then called an engineer from Honda. The engineer advised that the sound is from cylinder. They are now asking to get the cylinder changed which would cost around Rs. 25000. I am a bit skeptical now and need your advise as I am not sure if this is going to fix the issue. They have already changed a lot of parts and now this cylinder
Below is a link to two very short audio clips I have uploaded to my Onedrive. Please listen to them and advise
Thanks in advance
[MENTION=23793]mod[/MENTION]s: I am not sure how I should attach these 2 audio clips so I attached this Onedrive link. Please let me know if this is not as per the forum rules and I will remove this link but please also suggest how I can attach these clips.
