Since I have started selling MOTTY AFR in Norway I have removed the secondary throttle blades from the following bikes: Hayabusa 08, B-King, Gsxr 1000 K3, z1000 and ZZR 1400 ( ZX14 ) and ALL have performed BETTER after we have removed the throtleblades. When I view the logg I can see that the MOTTY has added up to 60 units of fuel ( out of around 160 ) in several places at low rews.
Without a MOTTY ( or a PCV ) its not easy to adjust the fueling so if you don't own a dynobench yourself you better leave it in.
