The Yellow Box
This product is manufactured by an Australian company called Black Robotics it allows easy recalibration of electronic motorcycle speedometers. It can be used to correct speedometer errors caused by the gear ratio changes due to sprocket swapping. I will provide a more detailed write-up on mating it to my GSXR1000 when I get it.

Some people have asked me inquiring about the Yellow box write-up. Looks like it is not going to happen. Here is the story:
I went to purchase it from the Black Robotics' web site and noticed a an offer for a free Yellow Box for the exchange of advertising and reviewing it on a web site. I E-Mailed Roman Black and made an offer to review it on my site. Roman E-Mailed me back saying that he liked my site and will mail me the Yellow Box after I place a link and a picture of Yellow Box on my web page. Changed my web site to include pictures and links as requested.
This was initiated in August, for the past 4 months I repeatedly E-mailed Roman asking him if we still have a deal. He repeatedly promised to mail it out "next week", well it never happened. I am convinced that Roman and Black Robotics never intended to ship me the yellow box and instead were scamming me for free advertising.
At this point it is not the money thing, it never was. I will not purchase the yellow box from a dishonest company like Black Robotics.
Here are some E-mails you be the judge:

Hello Yellow Box guys! I have a cool website where I can do a write-up on
your product. I am also an amateur racer and can run your sticker on my
race
bike.
Please let me know if you are interested.

Hi Glen, I like your site! If you can give
our product
a simple review on your page with a link and maybe a
picture that would be great! Just let me know if this
is ok and where to send the freebie to.
:o)
We are selling a few now to GSXR1000 owners to fix
the 186mph speed and limiting, which is cool.

Hi Roman,
Just wondering if you ever had a chance to send out the yellow box? I just
want to make sure it did not get lost in the mail.
Thanks!

Hi Glen, sorry I went for a few days
riding, with
the recent US vents all our airmail was stopped
for a week or so and I thought it was a good time
to go away on a riding trip. :o)

Hi Roman,
I am not pressing. Just trying to find out if you are still willing to
ship it or if something had changed. Please let me know.
Thanks!

We sent some last week, by airmail which is our
usual method, just waiting now to see if the USA
end of the airmail deal is working ok. If that goes
well we have a lot more ready to send. :o)
This BS went on and on.... I guess Black Robotics have a "get as many suckers as you can to post their product" advertising strategy...
