I'm starting this thread to see and share just DLE engine mods and results.

For starters I'm playing with a 20RA that's being rebuilt post crash. The head and crank took most of the impact straight in so I'm replacing the head, gaskets, both bearings and the piston ring. The crank checked out but the main bearing seems tight so for $3 a piece I'm replacing both. I considered BOCA performance bearings but I'm looking for a certain result first before I go that far.

First mod:
The left and right transfer ports have this nice blunt divider leading edge so I filed it to a sharp edge.
