Thanks for all of your suggestions.
It sound like "a thin clicking" like gas hitting thin pipes sidewall from exhaust head port to HTEV valve.
I initially thought could be an exhaust small leak or small crack. I can hear clicking driving... am i paranoid?
i replace all my old oil & oil filter by myself about three days ago but noise it's unchanged. Really and exactly the same.
I bought 4 liters of Castrol R4 superbike 10W40 and original oil filter.
Previous owner oil was not so bad and level on the check window was correct before and after the replacement.
Do you think full sinthetic "Castrol R4" 10W40 too "thin" for this engine?
I read of a bullettin saying that Castrol GPS mineral based semisinthetic
should be mandatory avoided on this engine so i took R4.
I ask two honda service to ear my engine: they all say it is normal
but i would ask other engines so i hope i'll be a little less worried.
i dislike that older 919 engine were so less noisy! and from what i can read 954 are less noisy too!
