Juanes,I'm tuneing my 75ius and it to also shakes like creazy but I think I finally got it to vibrate less changed the prop for a more better balanced one and tuned it a little better right now just trying to get a better idle off of it. but I think they all vibrate alot while in breakin it should smooth out after the breakin. but time will tell. hey buy any chance are u related to juanes el cantante?
jajajajaja
