700XX project - drag!!!
So, I have a few friends who have started to drag out their ATVs for racing. So far, 400ex, 450, and Raptor 700 have been tricked out - exhaust kits, rejets, extensions, bore outs, etc.
Well, I raced all of these with my STOCK 700XX and smoked all but the Raptor of course, that b**ch. haha 
So, here is what I have purchased an have on the way  :
Renthal Front Sprocket 15 Tooth
HMF Competition Series Exhaust
HMF EFI
Pro Designs K&N Air Filter
K&N Oil Filter (just for maintenance)
Green 200 light LED kit (for looks - for the motor and center to point towards ground)
4 x White 10mm led with aluminum housing (for looks - one to point on the bottom back of each tire)
Now, what I am looking for is a bigger/better air box lid or mod instructions to get more air flow and recommendations for other upgrades. I AM NOT AND WILL NOT be boring out the motor...sorry.
Also, how much HP/speed should I see out of these upgrades? I want to leave that Raptor in the dust

Welcome to the forums! If you are not going to go into the motor with the mods you mentioned you might run neck to neck, will have to do motor mods to smoke his butt.

What motor mods would you recommend? I would REALLY not like to bore it out any till I blow something :P
I am still looking to buy a different air box lid or a place to buy another stock lid to modify. Know of any?

If you are just doing drag racing, eliminate the airbox completely. Run just an exposed filter, Put a more aggresive cam in too. If the Raptor is breaking 100mph, you need some big motor work to touch him.

You will deffinetly need more than just those mods to get to 100+.Cam port polish then you may beat him.

So do what to the camshaft?
Will be doing trails still...so keeping the air box.
Right now I am running 80mph...so hoping to at least hit 90 with these upgrades.

You will hit 90 you could hit 150 with the right gearing but you wouldn't get there fast.
