    hello everyone

    since yesterday, a new noise appeared from my engine after 5-10 mins of riding





    My mechanics said it wasn't worrying him, but still, never ever heard this noise from previous f800's

    Should I worry?

    Not sure I hear what you're hearing...

    Does the sound change if you hold the clutch lever in?

    And the eternal question: When was the last time you changed your oil and filter ... ?
    it's kinda like an "oil thead" question... :photog

    Thanks for tthe reply

    Didn't noticed any difference with the clutch lever in, I'l try

    The last oil and filter change was done 10 month ago by my mechanic/dealer

    you think this might be the oil?

    Sounds pretty normal to me.

    If there is an issue oil would be amongst the least likely suspects.

    I'm hearing a sort of growling sound, not the usual one, but at the same time as the engine one, coming from the right side, no matter if the clutch is pulled or not

    Sounds to me like timing chain gears whizzing up.

    I know it sounds stupid to suspect the oil, but I've been on the forum here following the twins since before they were available,
    and it's happened more than a few times that "funny noises" were fixed by an oil and filter change.
    I can't explain it ... it's just an observation :photog

    and if it did fix it ... that would be a fine $30 bucks spent....

    As far as oil changes and oil life goes... ALL of the bikes I have ever had (I am 63 and have been hiding since the age of 8) that had a manual clutch and transmission began developing notable issues shifting, etc. at around 2500-3000 miles on the oil after a change depending on oil capacity of the cases. This is average for bikes that hold around 3L or 3 quarts of oil. Bikes with less capacity will require more frequent changes IMO and experience.

    I don't care what the recommended manufacturer oil change interval is I can notice a difference in shifting at those miles no matter the total miles on the bike.
    These are not like automotive or two stroke engines or even Harleys, etc. where you have separate oil for the engine and transmission/clutch. The oil in the crankcase needs to perform three different tasks and is spent after a few thousand miles. Weird noises are a definite possibility and an oil change is the least expensive and most important maintenance you can perform on a bike. This also gives you a chance to inspect the magnetic oil drain plug for metal and if present I would recommend cutting the filter open for inspection as well.

    Thank everyone for the replies (and apologies for the lack of response, but... well other priorities, mucho work, bad period,you know what I mean...)

    the noise is just getting louder and louder, I tried to isolate it, it's this weird growl when I rev up



    Last time I went to the dealer, he fond a small leak coming from the oil pressure sender installed in place of the stupid bolt, and just said " thats because of that, it cause a pressure problem, but I still don't hear it"

    Sender removed, stupid bolt installed, no oil leak, still the noise...
