Valve and bolt tweak
With the advent of warmer weather, I've got the tinker itch again.
For giggles, I'm thinking of tapping and capping all the holes in the valve that aren't actually in use, just to see what it does to the efficiency and velocity.
This would obviously be done on a spare valve.
Has anyone here actually done this, so as to give some commentary on the mod?
EDIT: Also, it would appear I'm the only person on the planet who hasn't opened up the valve to 3/16". Any clue as to the velocity/efficiency change this will bring?
