Airbox mod question

[Gearhead]

I've read a number of posts on the VR airbox but don't remember much on the square "stack" in the middle of the filter element. What's its purpose - mainly intake noise abatement perhaps? Has anybody removed or shortened it? Its top edge, stock, is between 1/2" and 3/4" from the underside of the filter element. Any results to report?

 

I know the box is very sensitve to having the top on, and some people like to have some 1/2" holes in the top. But this stack looks like a "flow torture device" to me!

Many folks have experimented with this modification:

 

Before you do anything, Remove the cover, and try to ride your bike around the block. You will find that the engine runs, BAD, with the cover removed. ( if at all )

 

I have put 6 , 1/2 inch holes on each side of the cover, Bike runs good, however the Intake Noise gets very loud.

 

I pluged half the holes, and ran 3 on each side of the cover. Performance , may or may not have improved. But thats a very subjective comment.

 

Don't make any radical changes to the air box.

My excuse for drilling holes in the top of the airbox was I live at 4500 ft altitude and traveled a lot of the time at even higher altitudes..The bike was running a bit sluggish so I surmised it needed more air...I started out by drilling six 1/2"holes in the lid of the airbox which after a while seemed like too many so I put duct tape on 2 of them..A while later I taped over 2 more..The bike seems to be at its best with just 2 open holes in the airbox...It has more power and the gas mileage is better...

 

My point is you may have to experiment a little and see what work for you

So is there anybody here who has played around with the stack inside the filter element?

Imagine the possibilities if the box were smaller and battery relocated?????????????????????? joe
