Hi Tiny
Did they run the engine in the road race bike blown , or did you add the blower?
The #4 hole chamber & valves looks a bit wet, did it oil in there because of a bad stem seal or oil ring?
Looks like a bore size of about 2.500 dia ?

Honda never planned on some nutter fitting a blower Don, they left that job to me
After it holed the piston,,it idled until I made it off the track, there's just a little hole in the piston that let the oil into the chamber until I killed the ign.
Bore size 48.5 mm stroke about 34m ? from memory.
This is an opportunity to lower the static comp. ratio, and get rid of the stock valve overlap I guess, the cost of which scares me. seeing as it was just a "stocking filler" project.
