yah say if you go and buy a k&n filter, remove your lid and go with a full yoshimura exhaust, you call call up yoshimura directly, tell them your mods, where your located and they will tell you exactly what jets to get
I prolly have about 20 different jet sizes laying around…me and my dad always did our jetting by trial and error.
starts bucking mid/top end…feel a loss of power then the jet is too big = running rich
running lean usually feels like it has the same power everywhere…plus the plug will be white…
same thing as a car when it comes to jetting and reading plugs.
