What jets are in there?

Some people don't seem to notice but most of the standard Japanese aftermarket systems were designed to run with stock Jetting.

My Yamamoto system runs perfect on 115/118's.

Havn't had time to dyno is yet to dial it in but from the feel of the bike it won't be needing anything bigger.
