ok u guys i need help i just finished installing a k&n sn-2550 filter, and finished dyno jetting stage 3 on my quad runs great really , but on problem i still have the stock airbox with the filter why use it if i dont need i by the the way i also got a coverfor the filter. yeh so why need the airbox so i removed the airbox and that big tube that sucks in air but the little tube on the right i notice thtas the one that throws oil in my airbox somtimes. what should i do leave it hanging, is there somthing i could buy for it or leave the box. need help fast cuase tommorow goin to red sands and ride pls pls need advice

 

The smaller tube is normally the casevent... get a small filter and mount it where it won't make a mess. The larger tube (or snorkle) may be necessary for proper air flow. In most bikes it creates a vortex and gets the air flowing smooth. When you remove it,the air tumbles into the carb instead of flowing smoothly. I don't know about your particular application, but I would guess that it would be better to keep it with the filter at the end... I could be wrong but I haven't seen many bikes that benefit from removing the intake snorkle. The Predator uses the same carb as the Can Am DS650 and I can tell you that removing the snorkle on the DS makes less power. Hope that helps and good luck getting her ready for the trip.

 

thanks alot

 

Removing the tube, does NOT make less power!! If you put a strait clamp on, it does. You need(for a clamp on), a Twin Air filter.......it has a shorter tube.......also, you'll need a crankcase breather.

 

do u have one if so were did u buy it

 

does that mean that you can put efi on a pred just like you can on a ds650?

 

I have one........I bought it at www.nicholascycle.com at their store though.
