There is a difference between turbulent air and pulsed air, the underside of a 916 tank in conjunction with the airbox is specially designed to use the pulsing to help produce power by way of acting as a Helmholtz resonator, something Shazaam! did a great post on years ago.

Not sure what you think your air useage is

here are a few questions that may help you answer that

A, How many cc's of petrol do you use in a race
B, What air/fuel mixture do you run
c, How long is the race in minutes

Here's Shazaam's post

in it Larry mentions 130% of the capacity. so for a 620 thats 803cc so less than a litre between the butterflies and the air filter, for my 1000SS it woule be a figure of 1300cc so as they run the same airbox I doubt if my Class A bike is finding it a restriction

Should have listened to Bob Dylan Si, the answer is blowing in the wind.

You have the lid off yours phil, how do you secure your filter?

[bradders]

you can either cut the lid out, mine was, or use lockwire/duck tape (done that too!)

Mine is fully open, to suck the birds in.

Thats almost a sexual offence (ill get my coat).

I just through away everything that seemed heavy and I might not need...... including the air box.....

then replaced most of it 'coz it turns out that I did need it.

I put a couple of sponge filters on the end of the inlets,, did the job.
