When my 80 Series has sat, like overnight, and I get in to take off I experience a (feels like front-end) vibration on initial acceleration up to highway speed, sometimes quite rough as though front right wheel is about to fall off until highway speed is reached. Note: I climb a couple steady uphill grades when leaving house until road levels out, but after that, or once "warmed up", it stops and smooths out for remainder of the day regardless of climbing grade or acceleration/ speed whatever. Vibration just disappears until next day when I depart the house again.
What would this be ??
