Boosted a bit of mid,
1-3 in the upper mid,  Revs higher with more power.
2-3 at peak and
extends the peak  rpm 700 to 1000 rpm higher, where it's 3-4 hp stronger at 14.5k rpm than stock stacks

 when measured under loaded dyno testing conditions on a bike with stock cam timing

Generally, we don't usually remap the FI when doing stack design, preferring to design stacks that improve power without creating humps and hollows in the fuel delivery curve.

The Factory pro Stack advantages are better average upper midrange and the addition of a "triangle of high rpm power" (that wasn't there before). Instead of power dropping off just over 14k and shifting at about 14.3k, now, you have an extra 700 - 1000 rpm of increased powerband and better peak power that wasn't there before.

The base test and the R&D final testing was done on the same day with a  BMC Race filter (as I think that just about everyone is using one). The stack power results should be the same powerband peak power differences with stock, stock w/ screen removed, K&N, Pipercross, Uni air filters.

Uses all stock mounting screws and air filter access is retained.

EVO Shift STAR kit

It's everything that I ever wanted to do to a shift mechanism -
Slightly stronger detent spring - a new MicroBearing detent arm and the final piece... A completely redesigned, empirically refined, multi angled, variable radii, repeaked and valleyed:
EVO  DETENT STAR
This part will totally change the feel of the bike as a whole. The shifting effort is about the same - but the speed at which the gears actually engage is dramatically improved - Quicker, easier, shifting - A "twitch" on the lever and the throttle and you are in the next gear! Perfect for track use and road riding for effortless downshifts into a corner and just a "tap" to upshift without any more than a "twitch" off the throttle -

That's not even mentioning that missed shifts virtually disappear!

Proven concept - Virtually all the Factory Pro Support riders in the AMA and WERA multi- Champions Vesrah Racing tested and proved the EVO-7 Stars in 2003.

Stock shift performance that everybody used to take as a "given" will be regarded as "slow and lazy" after riding a bike with this kit -

Kit includes the new Factory Pro designed Shift Kit, a new Factory Pro detent arm with a low friction microbearing roller, a new Factory Pro shift spring and the NEW Factory Pro EVO Detent Star.

Make shifting MUCH quicker. MUCH easier, MUCH lighter and virtually eliminate missed shifts.

...................................................

• How do you know that a transmission is shifting quicker and more reliably?

  • You can feel it when riding. Fewer missed shifts.

  • Your "quickshifter" equipped bike shifts clunkily after an EVO Shift STAR kit install and you have to decrease "shift kill time" by 5 to 10ms to accommodate the EVO STAR's quicker shifting.

    • That 5 to 10ms is now converted to "engine power" time, rather than "engine kill" time. That will improve power delivery time on a racetrack and at the drags.
