Anyone know what the settings are for a speedo healer on a 1000rr with a 15T front sprocket and a 44T rear sprocket?

I'm having the sprockets installed tomorrow so I was hoping that I called install my speedo healer tonight with all the right settings.

 

Easy - what are the stock sprockets? Front divided by rear as a ratio. Compare that ratio to the NEW ratio of Front divided by rear. That will give you a change...

I don't know your old numbers but use this as an example:

OLD = 16f 43r = 0.372093
NEW = 15f 44r = 0.340909

(NEW-OLD)/OLD
= .0839 or about -8.4%

Use the right numbers and you should be in the right ball park... remember this should put the bike back to the stock error and will not match a GPS reading. You should test this correction factor against something else, another bike or a measured mile.

 

the speedohealer website has a calculator where you put in your old vs new settings and it will calculate the speedohealer setting for you

 

I have the same setup and I set mine to -16.1% and it seems to be pretty damn close. I have onlytested this by pacing myself off of other vehicles on the road. If I'm in a 50mph zone stuck behind a line of cars and I look down at my speedo it says 50. Good enough for me.

I use the speedo healer calculator on their web site because it calibrates for the gear change, the factory error of 5% plus has a tire wear setting and you can adujust your bike for speed or trip or best of both. Iuse it all the time and its pretty damn close to my GPS

 

Why is there a 5% factory speedo error when it is so easy to fix this problem with a change to the computer?

 

Factory error is an over reading of speed - means that if there is tire wear it doesn't under read and you can't argue that honda sold you a bike that got youa speeding ticket.
