I wanted better intake airflow but didn't want to have to go around every tiny puddle on the trail. I ended up cutting the lid above the water baffle and removing the snorkel end cap. Any incoming water still hits the back of the airbox and runs out the bottom instead of drenching the filter. There is also a 150 main jet and an FMF Ti4 slip on installed. The end result is great, the bike is much quicker revving and feels stronger compared to the sedated stock setup. I still need to grab an adjustable needle and fine tune a bit.
