Pro Shift Kit
The Microbearing detent
arm and spring kit.
The "roller bearing detent
arm, FP spring and
a gasket" kits are designed
to get rid of most missed
shifts, are about 10%-15%
firmer than stock to shift,
but do the job of speeding
up shifting and help keeping
missed shifts from damaging
your gears. Firmer spring
to speed up shifting and
less friction with the roller
bearing to let the shift
drum move quicker.

We introduced the "Pro Shift Kit".
In this step, we added
some elegance to the concept - We build
new detent arms equipped with a microbearing
instead of a riveted disc, as many stock
arms have. This time, instead of just "pushing
harder" like the first "Shift Kits", we
went the next step and removed a bunch of
rotational friction - so with the slightly
heavier spring to push harder and the microbearing
to reduce friction - ahhh!!! Even
easier, even quicker and it made missing
a shift as rare as a lottery win in a 300
million lottery or that call from that big
Typical Pro Shift Kit
kits usually include these parts
+ a gasket)
I want you to know that I was really impressed
with the shift kit in my Kawasaki 636 ZX
The bike (not me) has missed shifts before
and once I got the kit in it not only didn't
anymore but felt smooth and positive and
actually easier all around to shift it.
The best part
of it was I just didn't have any attention
on it at all.
Thank you for making such a fine product.

Subject: Re: VFR Shift Kit Order
Your timing is perfect - I just rode it
today for the first time since installing
the vfr750 Shift Kit. Outstanding! I had
read posts on the VFR sites about how it
was so stiff and much tighter than stock,
so I was expecting a difficult transition.
I found it much more positive than the stock,
I did not get any false neutrals downshifting
to first, and It felt butter smooth in all
gears. I have been wrenching for years and
I followed your very detailed instructions
carefully. I will admit that shifting through
the gears with my hand on the shifter was
more difficult than using my boot! Thanks
for a great product!
Comment: My experience
is that the VFR people who used our microbearing
detent arm but ended up not using the supplied
spring and, instead, used the stock spring
were often the guys who rode in cloth-topped
athletic shoes. That's ok, because, even
with the stock spring, it will still be
better than stock shifting. Marc
I got the shift kit installed, and it
works like a charm.
