So I just picked up a brand new 2015 YZ450 from the dealership Tuesday. I've been doing a lot of research but I can't find the best and most useful definitive way to reroute the the crankcase breather. I've read a few topics and I really like adding a KN type filter to the end it seems the most easiest and economic way. However is it the safest, I don't want to blow my valve gaskets?? What do most people usually do? And if I were to do the KN filter what size is the crankcase tube diameter (I'm at work right now and I can't measure it). Any info would be awesome
