I was just curious. I get a vibration or buzz, if you will, at 7k rpm. I feel it most in the tank since it is between my legs. I'm not too concerned because it is just at 7k. Does anyone elses '03 do the same thing?
most inline 4's will exibit a vibration in that area 6-8k rpm.
Unless its a big vibration its nothing to worry about.
This is why your hands will tend to get numb on longer highway rides when your holding a speed around 90-140kph.
Everyone's right... including SB... underlying message is that synthetic oil makes a bit of a difference - I noticed it first ride and right away... but combining stratospheric revvability and lighter and lighter weight, inline four middleweights are going to have some buzz to them.
