yes, you can leave the bottom of the air box on. i did , and all works well and fits well. Plus it comes with a K&N crankcase filter and outerwear (waterproof) for both filters.

 

well i got my intake kit on and i like it better than my air force kit power wise really cant tell yet will go racing this week end to see if i can still beat my buddys raptor. i could easly beat him with the clamp on. may have to do some jetting dont no yet.

 

Just orderd the kit today after thinking about it for a while. 200 bones is alot for a intake kit, but I think from some studying and talking to some poeple which know alot this kit is the best. I had the SBS kit which put out some great power, but I just could not trust the cut out after the filter and it took to much maintance to keep clean. If anyone has any ideas of what jetting I should run it whould really help , I would like to get the jetting right the first time if possiable because the State closed down my riding-testing area that was just out side of town. I'm running the W/B Pure Polaris pipe with 8 disc and spark aarester. And I have a 55 pilot with my spring cut. THANKS

 

I am running a 200 main and the spark plug was a medium brown. I did have to lift the needle to the 4th clip to get it to respond immediately when I hit the throttle. I think it gets so much air when you open the throttle it actually gets lean right away since there is no accelerator pump. I also have a 50 pilot. When I let off the throttle it gave a rich backfire but turning in the fuel screw eliminated most of this. Don't know if it is perfect yet but it is strong enough that I went to a 15/37 sprocket combo on my 18" tires. I like how it can pull strong in 2nd and 3rd and running tall gears reduces...shifting.

 

im running 200 main seems to run best at this setting. no back fireing at all.

 

well not impressed so far with hs intake kit need to do more jetting i guess. cuz the clamp on that i have is better so far. and makes more power.

 

any body want to buy a high flow intake. take 140.00 new.

 

why don't you like it? was considering it but now may reconsider

 

maybe you will have better luck than i im having. i would say its not worth 200.00 just my opinion. i went back with my clamp on. i think its getting to much air. maybe ill try bigger than 200 main later on little disgusted right now.
