I think your going to have to rejet your carbs and if you want better airflow remove your airbox lid or cut a huge square in the middle.Thats what I did because my airbox lid has brackets that keep the filter in place and I didnt want the air filter to fall out of place so now my lid is 2 pieces.What are any mods or changes will I need to make to my Z if I put an aftermarket exhuast on my Z?[/b]
Wow thats pretty neat I bet it works well also.On the Z the air filter is screw to the box. The plastic "cage" inside the foam filter actually gets screwed to the air box......talk about a good design[/b]
