I was just told about the intake boot from the carb to the cylinder. It seems the one from the z is smaller than the one from the DRZ (dirtbike). They bolt right up and I think the guy at the dealer said it was about 30.00.
It really opens the intake to allow more air flow. I will look into this deeper.

air box lid

I bought a stock lid for my 300ex, drilled and installed some of those 1" vents and WOW what a difference!!! I plan to do the same with the NEW Z. Just remember to put the solid one one if you think your gonna take the Z swimming! 8O :D

Bio - I just did the same thing to my Z.. I Added a Uni and removed the snorkle. Put 5 of those 1" vented holes in the top of the lid, and I think air flow really increased. I'm having to run a 152.5 main and I'm going up to the 155... Removing the snorkle will open up alot by itself.. That thing is really restrictive..
