i wanted to know if i took off the airbox lid on my quad, would it do anything for me? good or bad? you can see the mods i already have in my sig

 

come on.. no one??

 

ya, it will help it breath better, which means more power. you may need to rejet though...

 

I wouldn't take it off. I just cut 4 1" holes and added vents. this way it breathes good and still has protection if I cross mud or water. If you take your air box completely off without rejetting you"ll make it run to lean and burn her up.

 

good idea. i'll try that

I also changed the main jet all the way up to a 112 and it runs great!!

 

or you could get an EHS racing lid, mine works great............www.ehsracing.com

 

If you don't ride in mud and cross deep water you could just remove the lid completely and rejet. When I had my recon, which had the same motor as the 250ex, I ran it with the airbox lid off. The stock snorkel on the 250ex and recon has a hole smaller than a quarter for the air to pass through, so removing the lid makes enough difference that you will feel more power and better throttle response, and it gives it a pretty cool sound.

 

Removing your airbox will help your top end (more revs= more air...more surface air on the filter=more air allowed into the motor) You could get a PD filter kit and cut the airbox around the intake tube. But don't do that if your going thru much if any water... Just remove the airbox lid get a PD filter kit and that'll do enough.

 

what would the pro design have to do with removing the airbox? The ex has a clamp on filter from the factory!
