yfz450 modifications .twist throttle?air box?

I have just broken in my new yfz and i love it,now its time do some mods.It is completely stock.
first i get a sore thumb after a long rides,i heard about changing over to a twist throttle and i have seen three differant types,vortex,cr pro and cr comp does anyone know what the differance is and what would be the best?I also ride a yz490 so i am use to a twist throttle.
I also realize that the response from the start is not there unless i rev it up, other than that it hauls butt.
can anyone suggest what to do?i heard of people taking their baffles out, does that work?how about removing the air box completly?
thanks John

YES, it works to remove the baffle and airbox lid, then rejet, and you will make around 20% more power, there is all kinds of things you can do to that thing to make power, but the quikest cheapest way is just that-remove the baffle and airbox lid, then rejet,and to rejet is WAY EASY, pull the plug out of the bottom of the float bowl(after shutting off gas) then with a 7mm socket remove the main jet, go up 2 sizes and reinstall, JUST THAT SIMPLE

I think the YZF twist throttle may fit on that, I may be wrong though.......Anyone else have a YFZ on here with a twist?

I have an rm and a zilla I put a twisty on the zilla and have regretted it ever since wish I had kept the thumb throttle! twisty is great on a bike but on a quad it maked it real easy to sprain a wrist if you jump alot
