Engine runs a bit cooler and smoother.
No slide drilling required. The same as 1.0 kit, but with Titanium needles, drop-in kit. The BMC filter is spaced more properly for the FZR as compared to other brands of individual air filters and doesn't distort air filter flanges, lessening the chance of allowing unfiltered air to enter the engine. Includes Factory Pro Microbearinged Detent Arm, heavy duty detent spring and gasket. Makes shifting more positive at the expense of slightly stiffer shift lever action.
