If they removed the engine, I would look at alignment. If the Rocker has a front motor mount at the tip that looks like a doughnut(not familiar with this model), look for the engine mount to be centered evenly on the rubber bushing. Check for any untorqued mounting bolts using final torque numbers below. The correct sequence for engine removal & replacement (if Rocker has same mounting hardware as a '06-07 FLHT) is: (1) transmission bolts to engine case finger tight, then 15 ft-lbs, then 30-35 ft-lbs. final torque {aligns transmission to engine} (2) the pivot shaft {goes through rear of transmission to align engine & trans with rear swingarm and requires special alignment tool if similar to FLHT with rubber bushings} to 90-110 ft-lbs (3) the front mount {sets engine and transmission aligned with swingarm to frame} 70-80 ft-lbs. (4) small bracket on right side of transmission to frame {locks all in} 30-35 ft-lbs 5) Upper bracket {between cylinders} head bolt support 28-35 ft-lbs, then the support assembly 45-50 ft-lbs {#4 & 5 lock all in & support upper engine movement}. Should get yourself a service manual (if don't have already) and you'll find alignment specifics for the Rocker in Chapter 2. Good luck, Rockin'!
