Hey guys I have a 2006 R6 i bought brand new about 4 months ago I got my first service at 1000k, and followed manufacturer guidelines for break in. I am now at about 4200k, anyways last week I let my bike sit without riding it for about 7 days and tuesday i fired it up and road it pretty much all day, but I noticed it felt different and sounded different, it felt as though i had a vibration when i accelerate. so then yesterday i got on it again and same thing so i took it to the dealer and got the service guy to take it for a rip and he said he could feel a vibration in the engine but its probably nothing. well i am not a mechanic but i know how my bike runs being that i have put over 4000k on in 4 months. So the only thing that was different during the week i had it sitting was i let it sit in some heavy rain without the cover on.Basically my bike runs fine but it doesn't feel as smooth as it was. If anyone has any ideas on this matter please let me know.
