The engine runs fine and I have almost a full tank of gas, but when I hit a trail with whoops the bike tends to sputter and lose power momentarily and then regains itself after the whoops. It feels like the injector just isn't getting any or limited fuel at that time, but the tank is full of gas.
My mods are Cannister removal, FMF pipe and Programmer and air box flap removed.
Otherwise it runs great. climbs hills, goes down hills, through creek crossings, etc. It's just when hit a section of whoops that I loose power.
