Factory Pro's unique STACKABLE stacks work even better than the non adjustable "other" stacks.

The Factory Pro stacks are 2 option height adjustable for custom powerband tuning (but start with the "longer" setup).

Same or better topend than other stacks and better upper midrange, too. The other stacks are similar to just using our single plate.

Additional "stacker" plates avail for taller than suggested stacks. Stacker plates will probably fit the $600 Yosh stacks.

Used by Vesrah Racing on Cory West's gsxr600.

We try lots of different things = Like these super tall stacks that didn't work well on our engine setup.

The Shift STAR kit will speed up shifting 5ms to 15ms and almost eliminate missed shifts.

Upshifts are easier, with less "off-throttle"  dwell time and downshifts are quicker, essentially effortless and more secure.

Every missed shift bends the shift fork and rounds the dogs. When the shift finally completes, it puts a huge mechanical shock on the gear engagement dogs and teeth AND the damping springs in the clutch basket  - which transfers to the outer "fingers" on the clutch basket and "ears" of the friction discs. Not a good thing.

The "Suz STAR" is the secret that AMA guys use and was developed with the help of #1 VESRAH RACING.

A "must have" item.

Quickshifter notes:
If you install the STAR and shifting becomes clunky on the track, decrease shift kill duration in 5ms steps. Regular shift kill time was about 55, but with the STAR it's more like 45ms.
Next time you hear that the STAR "made the shifting clunky", they probably have a quickshifter and they probably didn't shorten up the "kill time".
