I have a 2" on mine with some tape over part of the intake. It works fine, same as my roommates, and he has a jet kit in his. I am going to try to down size mine to a 1.5" hose.

i have a 2" pvc setup, never had any problems with it...all you have to do is adjust the fuel mix screw to match the increased air coming into the engine.

I run mine 1.5" out of the box to 2" and all i did was turn up the idle a bit. works like a jewel. I've done two foremans the same way so far.

I said early on that with the 2" I had no problems, but I only rode the bike for about 30 minutes.
I rode it the other day, and it was bogging, and acting like it had no power while I was in the Everglades. Got it home and checked the spark plug, and found that it was running way to lean.
So I took a spare 165 jet(162 stock) and put it in, spaced the needle out with a small washer, clipped about 1/2" off of the spring, and adjust my air fuel mixture.
It seems to be running better, and has a little more go to it.
I am going riding tomorrow, I will let yall know what I find.
