	Air box design is an art all to its own. It's not just a matter of
	opening holes to let more air in. A good air box gives good even
	air distribution to the filter. It should also pass the air in
	such a way that forces the heavier dust particles out of the air
	before reaching the filter. Doesn't help you much for your next 
	ride though... Your idea will work. Have a look at late model
	KX's. They have these neat rotary plugs in the side of the air box
	which you can open up for more power, but close up for deep water.
	You may be able to buy some, or at least give you ideas about how
	to fabricate something similar.

	You're nuts...Years ago I tried racing an RM125 in Finke (big 
	desert race) against a heap of open bikes. I didn't get far...
	But it's fun being different though....Just resign yourself to the
	fact that in a straight line, you'll lose....BUT, towards the end
	of the race, you'll have a heap more energy to go fast. You'll
	probably have more fun too.

	Yea, give 'em heaps.....Just don't ever do that to me on the
	track....I get really pissed off when a little bike goes past me
	and I usually crash trying to get passed again....

	Don't get too excited about your air box mod... It'll help for
	sure, though remember that lots of little positive mods go
	together to make one damn fast bike. As my dear Dad once told me,
	"Son, the only way to eat an elephant is bite by bite..." 

	Have heaps of fun young Frampton...Loved your old man's live 
	album...

	Cheers
