when people are saying that they have no air box cap/lid does that mean that they have no cover over their air filter?? or took off the buffer on their exhaust? sorry i am confused

 

It is pretty much a waste of time and money to get an aftermarket exhaust or uncork a stock exhaust, and not increase the airflow from the air box as well! The easiest way to do that is to run without a lid, and also run a freeer flowing air filter. And of course....you will need to rejet!

I ride desert, and it is dusty!!! I can't say that I know many people who have their lids on, even in these conditions. What I do is run the EHS Racing lid with Outerwears. The Outerwears takes care of the worst of the dust, and I still get lots of air flow and increased performance.

 

so simply they take off the whole casing of the air box? hmm im riding on alot of sand aswell but beachy stuff lol

 

Some manufactures, like K&N, make a filter that replaces the stock air box lid. While you still maintain the original or after market pod filter, this allows much more air in.

 

Like scooter said, there are prefilters that replace the lid. I have a UM Racing aluminum air box on my preddy. I run a prefilter (outerwear) as a lid that velcros to the box, then I use a UNI foam filter. I also have a K&N filter with outerwear for the sand/spare. That, accompanied with a full aftermarket exhaust and proper jetting may yield the biggest gain in power you will experience.....certainly the least expensive!

 

sweet thanks guys i just put my precharger on my k&n filter and took the air lid off and also uncorked the exhaust for now still thinking which exhaust to get most likey hmf

 

I hope you know not to ride it until you re-jet it. If you're not prepared to do that, put your lid back on.

 

hmm to much air or sometthing so i should put my lid back on??

 

Without a rejet, you will be running lean (hot!) and melt a piston!!!

It was all the fashion back in the day to pull the airbox off completely, but I have seen info the indicates that the airbox provices a "dead space" that is necessary for the filter to efficiently suck air.

One note about K&N....my hard learned experience is that they pass fine dust, even with a precharger. Had them on everything for a while, but have gone back to UNI foam on everythng. Leave the K&N's for the street........

 

Just to clear it up... taking the airbox lid off means just the lid...

here's a pic of my LTR without the lid on.



Back when I was running the stock filter, of course (got a UNI installed now!).
