I was wondering if anyone has used the ram air kit for there bike and how did it perform? I found one someone is selling on ebay, and was wondering if it is worth purchasing?

i've never seen one or even heard of one. ?? does it even work??
replaces air box, does it still use an air filter?

 

I dont know thats what im trying to figure out. It says it replaces the original air box, but i dont remember it saying anything about the air filter

 

the ram air kits do work but it takes alot of work to put it on the bike. and you only feel the differance above 130 and 7000 rpms. when you put the kit on you have to move the radiator down about 3 inch's witch puts it closer to the header so you have to wrap the header or your bike will run hot. also you have to cut the upper where the air ram scoop comes out to make it fit without hitting the frontfender when you apply the brakes hard. if it was mee i would judt go with the FACTORY PRO AIRBOX MOD KIT. and jet the heck outa it. thats what i did and i love it.

 

+1, i totaly agree, pipe and jet it. and if thats not enough add a shot of NOS,
it's probly easier that installing that kit your looking at..

 

OK then, just to throw a spanner in the works, does NOS work on carbs or just inection?

 

NOS works on both carbs and fuel injected motors.

 

if your saw the same kit on ebay that I just saw its missing about half the components. Definetely stay away from that as its dicontinued I think. Plus the company that made that made two different versions because the first one performed poorly and it would be hard to know which one your getting.
