How about the timing chain?

Hmm then its not oil issue

why don't they give tubeless tyres on this beautiful machine?
anybody tried replacing the custom tyres with tubeless ones?

You can go for tubeless if u wish as karizma has alloy rims. But best would be to use a good tyre+a tuff up tube from honda, this will be very tough to puncture.

I feel it is due to the 10w30 oil that you are facing the metallic sound issue....In cars for older engines the recommended grade is 20w50 and they warn that if you use thinner oils there will be rattling noise and leaks..ie., meaning that a thicker oil is preferred...and after 63K Kms I think the same applies to your engine also...stick to 15w40 or 20w40 and do not use thinner oils. After running true for so many Kms the engine moving parts tolerance will be more than stock and this i think is causing the problem for you...

That sounds like the Timing Chain Tensioner. Change soon or it may warp your timing and cause expense

Sure its timing chain? Cause it goes away with load. I was thinking along the lines of slack in conrod bearings.

Not timing chain. The TIMING CHAIN TENSIONER. Its what keeps the timing chain from getting extra slack. Its near the starter motor. If the noise was from any conrod component, the noise would have been permanent, I think.

I have been using this Honda Throttle FS 10w30 oil very recently from just 250 kms. Previously I had been using 10w40 Sprinta FS. This metallic sound was there when using the 10w40 too. Its been there since 7-8k kms.

Feedback on Honda Throttle 10w30. Its better than regular 10w30 oil, bike warms up easily being thin oil. And compared to Sprinta 5000 10w40 FS, I felt both are almost similar, but Honda oil has better pickup slightly, may be because its a thin oil compared to Sprinta. Even the fuel efficiency level went up 2-3 kmpl compared to Sprinta FS.

Those who are using regular 10w30 grade, can go for this oil.

I too have the same noise coming from my engine which has done 5000kms, but as per my friend he too had this sound when his engine was new and now its a lot better after 20000 kms hopw it will be the same with me. I changed my oil from Gulf20w40 to Throttle10w30 and now the accileration has improved considerably engine feels much more lively and free reving, while I was using the gulf oil never felt the engine is this much capable but on 20w40 the bike was a bit more silent but felt a lot of drag in the engine anyway I am happy with Hondas synthetic oil and hope it will do its duty well.

Today bike didnt restart after a good high speed short run, cranked it couple of times the bike did start but died after few seconds like there was no petrol, so I opened the fuel filler cap and started and the bike was back to normal. I was thinking that after hearing so many same experience from other Karizma owners that I was lucky not to get the same issue but unfortunately the story is same all over the place any way its my wings and do under stand that the wings gets tired once in a while same like everything

In that case try changing the Timing chain Tensioner , and see if the sound repeats....if it does then something else,.... Timing Chain, cam,Valves,guides needs to be looked into...

@Psr sir,
I was thinking about trying Diesel engine oil after going through your posts, but since my oil change is not due for another 3k's more, thought about trying it on my Zen since its due for an oil change. And on some googling this is what I stumbled upon.

Am abit confused about the "cleaning out compression" part. Should I be worried?

You should be worried, since your facts are not clear to you....My personal opinion to you...don't experiment with anything different from stock,till you are aware of what you are walking into, and have the knowledge to offset any setback in your experiments...

For the time being planning to go for this, the spec says its suitable for both Petrol and Diesel blocks, nothing about ZDDP is mentioned though.
