After installing the street twin and the new flywheel i noticed little bit of vibration in higher rpms. From around 4k to 5ish i can feel little bit more vibration, its nothing major but its there. Its smooth as buter from 5ish to the revlimiter (6800). I was wondering if its because i didnt balance the flywheel, but if that was the cause, wouldnt it get even worse by 6800? I also have a poly mount so that probably is adding the vibrations, its nothing major, i am just wonderng.
