I've seen several conflicting suggestions about re-jetting with the addition of a Hypercharger and after market pipes. I understand the need but do I really need to mess with the needles? Second, anything wrong with the Kuryakan supplied jet kit? Thanks!

I've just put custom pipes on my 650 and - after talking to my mechanic - theres no need for rejetting - bike is running sweet as a nut and the pipes sound fabulous.

I was told to undo the battey fromthe terminals - install the pipes, then reconnect battery - wait 10 minutes then fire her up - apparently the ECU sorts it?
