300 ex
 

I have a 1993 Honda 300ex and I'm doing the 330 kit. I have all of the parts to do it right... KN,FMF pipe, stage 1 hot cam, the head is at the machine shop now for valve and head work and a Black box. My question is about the new cylinder. Is this extra pipe for an oil cooler? I was planning on putting one on eventually any way. Any input is helpful.
