Ordered The HSP Header and exhaust... Jetting?
you should go 1 size up on main and pilot,also set the needle clip in the fourth notch...thats what i've been told by hotseat.I have the pipes on my scrambler and it ran like crap before i jetted it.You have to jet it with the stock air filter and i believe with a k&n you can trash your engine overtime if not jetted properly.The HSP pipes tend to backfires a bit,you may have to play with the air fuel screw to make it stop.
