2008 Shadow Aero Tourer

[Heretic Wild]

Good day!

I ride a VTX1300C and my wife has a Shadow Aero.

I rode her bike yesterday from our house to our cottage (about 80 kms - mostly highway ) .

I put Cobra floorboards on her.

At highway speed, I can't keep my feet on her floorboards - a lot of vibration! I can feel vibration from the engine against my right leg from her air box when I put my feet on her Lindby crash bar.

My wife doesn't ride a lot - only has 3500 km on it.
Bike is 1 and a half years old and still looks new.

Do the valves need adjusting?

Thanks.
