I plan on taking off my raptors airbox snorkel for more air when I put on my pipe. What can I do with the hose that hooks into it? Does is come from the crankcase?

i believe that would be your crankcase breather hose. check the inside of that hose for any built up crud. ive been reading that this hose sucks dirt from unfiltered air. if left unchecked, you may eventually end up w/ debris in your oil. if you do eliminate the snorkel, cap the breather hose off w/ some sort of filtering devise. ive heard of people using everything from pantyhose to fuel filters. hope this helps.
