Lubrication after a top end rebuild

[Flysooner9]

Finishing putting a new cylinder and piston on a 787 RFI. Was wondering if I need to pre lube the cylinders at all since they are bone dry? Don’t want anything to seize up on the first start. Or will the injection system get oil there fast enough?

You should put oil on the piston pin bearings and a little on the cylinders but don't go crazy with it.

So just rub a little 2 stroke oil on it? Would some fogging work?

2 stroke oil would be better.
