How effective is the airbox modification??Is it worth doing?? ?

Do a search your question answers itself.

After that if you still question it buy a Vespa.

Most effective power / dollar (I guess pound for you) you will get. Call it the freebie. It will be your last. Or you can save it for last, and wish you did it first...... ?

Definately

More power, and much better gas mileage

Just to see how easy it was, I pulled the rubber snorkel out of my E model. It was way easy, but the hole it leaves behind is actually larger than 3x3. Is this going to be fine once I actually rejet and leave it off? ? (I put it back on for now as I don't have the jet kit yet).

Bike is an '05 California E model with the stinky Mikuni carb.
