Had a Pro-Charger equipped bike in here that some crafty soul had taken upon him/herself to arbitrarily drill the holes larger, with 5 in one, and 6 in the other, and different sizes as well.
Who on God's green earth is doing this handy little upgrade?

Shhhhhhh! You're giving away the secret Scott. No doubt we will see ads in the leading motorcycle rags soon, touting the benefits of these top secret injectors. When combined with their super duper plug wires and super duper fuel additive, they will add 20 hp and increase mileage by 50%, all for only $499.95 plus shipping. What a steal.

Btw, I assume the answer to your question is some old guy who is new to the idea of fuel injection. He probably figures he used to drill out the jets in his carbs, so why not the injectors?
