[QUOTE="2smoke, post: 45720, member: 563"] Also you state that your not getting the power that you thought you should. OK.................. Not getting power where? On the bottom end? Mid range? Top end? All of the above? Well I think Jackson and I are on the right track. He threw a bunch of new aftermarket performance bolt ons at it that require the jetting to be changed to see the full benifit of those new parts. At a minimum the new head pipe and reeds valve set up will require atleast on main jet size smaller maybe two. That and the pilot Jet will likely need to go up (I think) one size could be down. Not to mention your jet needle setting. Jetting and the jet needle position is where I would start. That and a fresh set of Plugs. Yes Plugs I go through 3-4 of them (just how I roll) Getting a bike jetted correctly. Oh I almost forgot. Did you repack you silencer? I only say that because you where kinda vuage on the FMF exhaust portion. New head pipe is great but will be hampered by a choked up silencer. [/QUOTE]
