Yellow box?

How's things with that speedo correction device, 99TLR or any of the "guinea-pigs"?

Just wondering as it would come in very handy to compensate for that 44T rear sprocket on mine.

I am wondering if my little project provoked some response just to try to stall me. Not sure but I am still working on My speedo correcter. I should say my engineer friend is. His is getting close to a prototype. Things have been moving slow because not many people seemed interested so we have not rushed.
If interested send email to jacque.day@murraystate.edu with speedo corrector in subject.
I will be posting some pic.s in a while on my web page.
 
Still Waiting, sort of like the old Heinz Ketchup commercial.

What product have you not waited for?

If it is Hayabusa it is either backordered or *in Production*
 
Wait till the ZX12 boys get some busa aftermarket kick-a-s-s put on them next year and they have to wait ....he he he he
 
Sorry guys, I only usually come here every couple of days, and I have been busier than usual this week.

Yep, the YB's are going well, the Australian tester got his a couple of days ago, the other units were sent airmail to the other testers on the same day, that was last Tuesday. It is Monday evening now as I write this. The postal worker said to expect about 1 week delivery to the US.

We are in production now and selling units although production figures are low due to only being able to encapsulate (set in a block of plastic) three units a day. That figure will increase to meet demand as soon as we get set up with the new CNC machined multi-unit molds (we have ben waiting 4 weeks for these already!)

If everyone wants them all ASAP we must have something pretty good huh? Or is it just that guys who ride sportbikes are all like big kids, ha ha... I know I AM when it comes to my bike! :)

PS. I have deliberately tried to play down the "Yellow Box" topic on this forum the last couple of weeks, free publicity is great and all that, but it would be unprofessional of me to keep thrusting this topic in front of everyone's nose every day. Reeks of spam. :)
We do have a web site;

And we are taking orders and shipping product, and will improve production numbers and the surface finish of our YB's when we get the large molds sorted in a couple of weeks. Thanks guys for your interest!
 
Nice to have turbo1300 in the same city. He has been good enought to allow me to install the yellow box (while I wait on mine - on order) on my bike as his is out of town.

I will install it in the morning. I hope all is well with, since I am one of the very few with *MAJOR* gear changes on this site and it would be nice to have accurate readings again.
 
recieved the yellow box to day!

it look pretty simple to install.

where have any of you been putting yours?

does it need to go under the seat?
have any of you found the sensor plug?
where is it located?
also, how are you coming up with what settings to set it at?
 
Hi Frank, re the installation, you can put it anywhere that won't get too hot or too wet. I would suggest mounting it somewhere you can easily flip the switches and see the digital display light up. You will probably want to adjust it a few times until you are happy with your speedo accuracy.

The epoxy casing we have used is quite durable, it will take a bit of punishment. I smacked one quite hard with a hammer a few times and it still worked fine. Up to 50 degree celcius should be ok, but like most electronic devices, the cooler you keep it the more years you will get out of it.

The sensor plug is easy to find, look on the cover over the countershaft sprocket, and you should find a little black device held on by one or two screws, with a black wire coming out of it. This is the sensor. The wire is about a foot long, and has a 3 pin plug at the end.

You can remove the sensor in a few seconds with a 4mm hex (allen) key. You may have to remove the left side fairing, on some bikes you can just remove a couple of fairing bolts and get your hand in far enough to reach the plug. With any wires you install, be sure to keep them away from engine and exhaust.

Re adjusting the unit, set all the switches to 0 and your speedo will read normally. Measure your speed (or distance) against an accurate reference (freeway markers ideal) and then you should have indicated speed and actual speed. Just divide indicated by actual, and you will get a ratio (probably about 1.06 for a stock 'Busa) and then use our reference table to give you the new switch settings.

Then look forward to having a 100% accurate speedo. Once your rear tyre gets quite worn,
you might want to adjust it 1% or 1.5% to compensate.
 
I am not sure how accurate the speed on the GPS is. Civilian GPS are only accurate to about 100ft so a test over a longer distance will give better accuracy.

My suggestion would be to pull over, reset your tripmeter, reset (home) the GPS, and drive for a set distance (say 10 miles) shown on the GPS to give actual distance, and compare with the indicated distance on your tripmeter.

The tripmeter counts the same incoming pulses as the speedo, so if the tripmeter reads correct distance you can assume the speedo is reading the correct speed.
