Just picked up a FMF powercore IV for my WR450 and have a JD kit on the way, my question is should I wait to put on the pipe until I have jetted my bike or is it cool to go ahead and put it on now. I ride mostly Carnigie and Hollister in California not very high elevation at all.

Id put the pipe on so you can use it as a baseline and test before you reach for the bottle of JD. You will base all jetting on it anyway.
