Re: Just got A Z400 What\'s The Best way to Break it in
With my z, i road it sanely for about a month. Came with the Yoshi complete system and once it was broken in I took it back to the dealer and they rejetted with a comple jet kit. I put the K&N kit on it before I took it back. It's completely dialed in and screems!!!! The Raptor or the new 450 may be a faster but the z will kick on the tighter rides.
