929 KPH to MPH conversion

Can anyone tell me if my 929 speedo which currently reads in KPH can be changed to MPH?
I have tried various button pushing combinations without success.
Do I have to send it off to some bloke on ebay to rip me off for £100 or is it just a case of knowing the sequence of button pressing?

Yes, myself as well. But could someone install a "Speedo Healer" and not only correct do to sprocket changes but also change KPH to MPH if neccesary?

Sure, all the SH does is add or subtract a percentage to the output shaft revolutions it's counting - it doesn't know if you're measuring speed in meters per second, or Mach numbers.

Re: 929 KPH to MPH conversion

Depends on the speedo. I've seen US bikes that will convert to KPH, yet Canadian models that won't convert to MPH when asked.

A speedohealer will be able to correct for inaccuracies as well as do a conversion, although the units on the speedo will still show the original units, which means the odometer will too.

If the bike isn't braking properly, you don't start by rebuilding the engine.

Yep, the European 929 Owner's Manual says that only "E" market bikes allow this, "E" being UK. Whether it includes the "ED" or non-UK/FR/DE markets I can't say.

Speedohealers _do not_ correct speedo inaccuracy, they only change the percentage, but since the percentage of error is directly related to traction and drag they can't allow for different speeds, particularly high speeds where drag plays a huge role in your level of traction or tyre slip.

It does allow you to get the reading a hell of a lot closer than stock though, and that's my point. Guess I wasn't specific enough

It can do that :-)
It just annoys me to see these things promoted for _accuracy_ that they don't do.

At what altitude though?
At sea level that'd be 150mph, at 60,000ft it'd only be 130mph ;-)

You tried pressing the button mentioned and it didn't work?

It was suggested in post #2 on a 954 and confirmed on a 929 in post #3.

Yes i've tried various combinations of button pressing with no luck.
Of course my 929 speedo is a different unit to the 954 model.
Has anyone had first hand experience with a 929?
