I ordered speedohealer does anyone know the calibration setting for stock gearing?

it will tell you in the calibration instructions

but good idea to check against a gps also

Thanks

I used a -8.8 percent factor in my speedo healer with stock gears and went out and measured a mile using the local hiway markers and did a time test and measure test and found that -8.8 percent made it totally accurate.

I also backed this up with my escort radar detector that has a gps feature and found that it matched exact.

So -8.8 percent for a stock geared zx14 is a magic number to install

depends on rear tire size too, ie...50 or 55 series.

stock tires and gearing is -7.0%

Your correction ratio depends on what speed you check it at, if your gps says 65 and your speedo says 70 that would be 7.1, if you check it at 80 the ratio will be less at 6.2. At 75 MPH my 14 read 80 and with the 42 rear sprocket the correction ratio was 8.6 total. When checked with GPS it was right on the money at every speed. Scott is correct when you check the speed at 70 and your speedo reads 5 MPH fast. You cant use your odometer as a guide now because it will actualy read a little less miles than you have actualy traveled ( that might be a good thing ) but the speedo will be right. Ted checked his at 60 MPH if the gps whould have been reading 55 that would have been 8.2.

i got the -7% off the heal-tech site(makers of speedo healer) for those that are mathmatically challenged like myself lol i held my bike at 100mph(by speedo) then watch gps it read 92mph so my bike is off -8% my gearing is stock and tire is stock height but a 200 wide wouldnt think that has any bearing on it. The ratio does not change through the speedo range if its 8% off at 100mph its 8% off at 25, 55, or 75mph

btw buck i got the grommets thanks a bunch

The side wall might be slightly taller on that 200 tire. You are right 100 and 92 = -8.0 sounds like you got it down! What did you think of the clamp Idea instead of the grommet on the back line. If I can find a black clamp around here I think I will do it that way.

Scott I see from the pic you do not have the high speed recall button plugged in. I was wondering if the cord was long enough in that location ?

Here is mine, but I hate my recall button location. Where are all you guys placing the button ? Dubious had a great spot in the bars for his. I may try his idea just curious to what you guys are doing.

Button on left, YUK

it would be long enough if they would have sent me that wire lol i just bought the harness and took the unit off my zx9 that way i can just switch unit back and forth when needed $30 is cheaper than $114 but i will be calling mon to se if i was supposed to get that recall wire too no biggie if not i never used the one on the 9 im more interested in the speedo being right.

I snaked mine up between the harness at the clutch lever/switch housing area.The speedohealer I mounted with a ziptie right down at the left ram duct,but accessible from the side of the ignition.Mine is set at -12.5(I'm pretty sure).190/50 tire on the rear....16/42 gearing.It is right on the money at every speed.(that setting came off the speedohealer website).

ordered my top recall button yesterday. fyi if anybody just needs to order a harness the recall wire does not come with it its an additional $7 dont know yet where ill put it

I'm running stock gearing, stock tire size and have speedohealer set @ -8.6 when I checked initial speed bike read 70 gps said 64. I have checked it with 3 different gps and all show its spot on.

Set it to gps.

mine is set at -8% and is rite on with gps stock gearing 200/50 tire

I have one but have no photo's of it. I like where Blue07 has his.

I had mine there for EVER...then,just recently,thought I'd change it up a bit.See that gap in the triple tree clamp there?Where the bolt tightens down?I slipped it right in there,button up(natch),and took a small piece of electrical tape and taped across that gap.Worked perfect.Inconspicuous but accessible.Better than "flopping" right there at the side part.

Here's mine. TSM button is routed to front right of instrument panel. Just hanging there peeking out but I will be fabbing a small bracket so it fits up there on the traingle with the dimples on the ram air cover.

It seems to me that with the 190/55 tire and the 17/45 gearing, my speedo seems to be running SLOW. Makes sense>>>bigger tire bigger sprocket = wheel turns fewer times to maintain a given speed. ok. So, when I go to the Speedohealer website and do the calibration for standard 17/41 gearing and standard 190/50 tire recalibrated for current 17/45 gearing and 190/55 tire I get -11.0% (that is with +5.5% speedo error compensation)

That sounds like my speedo will be indicating 11 percent slower? WTF? I guess I will just do as the calibrator suggests and see what happens but does -11.0% sound right?

I think you mean faster ?

but does -11.0% sound right?

yup.
