Wow, cool stuff
The pistons & connecting rods look delicious ! Didn't Honda once make an engine with oval pistons for it's Moto-GP NSR-500s or something ?
To the experts, what are those injectors on top of the intake trumpets ? I've seen them on some YouTube videos as well, are they for water or methanol injection ? The attention to detail is awesome, even the cam lobes have been hollowed-out !?!
