So I understand that there is some inherant noise to the desmo valves, but being a first time ducati owner I wanted a little peace of mind. I am at about 800 miles and at freeway speed, in 6th gear if i roll on tge throttle about halfway at about 5-6k there is a distinctly different type of tapping noise. Does anyone else hear that? Is it normal? Thanks in advance

I think I get the same noise. I've started to wear my ear plugs now because the termis were making my ears ring. With the ear plugs in you can't hear it anymore so I just ignore it. Think it's just a normal thing.

Just a quick one here, but what fuel RON are you running??? if it sounds like chopsticks hitting the floor (the sound your trying to describe), it could be "pinging" also known as pre-detonation, I note the user manual states a fuel octane rating of at least 95.
Otherwise, it's a new bike, covered by warranty, if you have a concern, drop it in to your dealer

I thought the manual said 91, which is what I run. Also that is the best gas that's easily accessible here in California. Off to double check now...

I knew this would happen, seen it on another forum, apparently the US have a different RON system to us here in Australia, US manual states minimum 90(RON+MON)/2, where as here in Australia it is a minimum 95RON.

My bad, should of asked your location

No worries, although to touch on your last post, I'm not sure I'd describe it quite like dropping chopsticks, but more like a tick. I know partly it's because I'm putting a little to much load on the motor instead of downshifting, and it goes away at about 6k rpm. But it still causes a bit of concern ;-)

Try using super unleaded every so often. I'm not worried about mine I just think its normal because the demo bike made the same noises.

 

[williamkgood2]

Cool I'll just keep an eye on it, or an ear. Thanks a lot for the replies

I alternate between Ron95 and 97..depending on which fuel grade the fuel-up station in the area is offering.
