04 R1 6-7000 RPM issue...

[MR JJ]

Just wanted to know regarding my 04 R1 about reaching between 6-7000 RPM while cruising it seems the engine sounding like different. More like a humming sound. And the RPM needle moves up and down while cruising, isn't suppose to be steady? Any idea about this? Thanks in advance.

does it cut out, lose power or just sound different?

how many km and what has been done to it?

Hey Paul thanks for replying no it doesn't lose power or cut out. It sounded different pretty sure is coming from the engine. 35000 klixx and i changed the spark plugs, air filter, new clutch, and the recall TPS. do you think that does it have to with valve adjustment coz i haven't done it yet.
