Anyone have any opinions on this, I was told open the airbox on a stock motor makes no power difference on a stock motor only more noise, what do you think?

More air equals more power.

[AtvMxRider]

That's why you rejet:blah .

[Sparks425Ex]

More Air=More Power. Simple as that. But you gotta get enough fuel to compensat for the extra air.(Rejet)

yeah my airbox had been modified, its got 1" holes with plactic inserts and foam to keep the dirt out yeah it sounds good but you will need to rejet for proper improvement

There will be a new review of an airbox I build that will help you decide what to do .There are several choices you can make on boxes you need to decide which is the best for you

well I cut the box and it's jetted seems to have made a difference, I think I may buy a custom High flow box.
