I agree with the two above, it would be nice to know what the full overhaul entailed. If the receipt doesn't specify details, you may be able to contact the guy (I presume) who did it. With only 2000 km on it and good compression the top end must be good, no de-coke or re-seating necessary. It would be a waste of time to mess with it. If you were to look at anything, you'd want to open the crank and check for built up crud in there, in case it wasn't done at the overhaul. However, the built up crank demands some level of mechanical aptitude to work on, as the six 1/4" bolts must be tightened to a pretty exact load. Using a normal torque wrench
on all the bolts can't be done, unless you device something special. The fitters at the factory apparently had it in the wrist, which, hopefully, do I...
In conclusion, I'd leave it and trust it's OK.
