Some things are not possible to tune on a dyno
and require track feedback to refine - that's
why a simple "delimited"
ecu reflash doesn't
provide that last 10% of power or silky driveability that a track refined ecu reflash
We have all learned that each bike, even with the same aftermarket
parts, requires different mapping than it's
identical twin bike.
That's why when someone "downloads the perfect mapping" off of
website for a pc or Bazzaz, that it only has a 10% chance of
being perfect "on YOUR bike".
With 35+ years of tuning experience, Factory Pro knows that the key
to silky smooth and str
ong running is individualized, perfect
tuning on each bike - That's why we do tuning for people all over.

Shift Star and F-Pro Spring
EVO Shift Star
It was really good, I was breaking
in new boots
and it was still much better than
the stock star and spring .
very happy with it! Thank you
S71 EVO Shift Star
stock 17-20 gsxr1000 star resembles an old sv650
star. Not a crisp shifting Factory Pro S71 star.
Specifically, the late
style gsxr shift action is very flat feeling and
gives very little tactile feedback as to
confidence that it's really in gear or not. I
hate it when you shift and you can hear the
shift mechanism sort of lazily "kathwaka"
into it's "maybe" final gear location. I like a
confident, proper "snick"!
They had it so close to "almost good" in
99 - I'm not sure why they changed it for the
"non-better".... Oh well - After redesigning and
testing and redesigning and testing, and
redesigning and testing...... I now see how easy
it is to get it wrong, though.
We have a new detent "star" with a copyrighted
profile (yep, the "science failed, so, it's
artwork - so it's copyrighted) that includes a
peculiar combination of compound arcs and radii
that produces a shift action that makes it
almost impossible to miss a shift ("almost" is
the key word here!), especially 2nd gear in
upshifts and all the downshifts - At least, if
you miss 2nd, now, you will be REALLY surprised
- cause it's now such a rare occurrence.
