I have put a 10w50 oil, the sound has improved in the valve train.

But I still don't know where that damn sound that only appears hot comes from, it could be normal as you have told me, but it makes me angry not knowing what it is.


Thanks guys.

Is this a rattle that goes away when you pull in the clutch lever?

No Intuit, noise is present whenever the engine is hot, I don't know what it can be. Here I show it, without any change:
I don't think it's the crank bearings ... I don't know what to check, I'm lost.

Muffler bearings in good condition?

I think that's Mordantly's way of saying it's fine. I agree. 😉

I just warmed mine up listening to it. Valve tick, cam chain, reeds for exhaust air injection, clutch throwout bearing all change sound as engine warms up.

This is a compilation of videos that I have found on the internet, there is nothing more to say, it seems to be normal, if it is a sign of failure, the future will tell everything.

it can be seen that when accelerating the same sound is heard.


I already showed this before.


This is undoubtedly the one that worries me the most, due to the failure it announces, you can see the same sound that I have, but also the unpleasant noise of broken bearings when accelerating more.

I think I'm going to stop worrying about this, for once. It is another bike if I compare it with the first day I buy it.

Thanks.
