SV1000S Speedo accuracy

[sinned]

I suspect the speedo on the SV1000SK6 may be reading high by about 10kph at 100kph. When I drive along the Wellington Sthn MW in the car most traffic is flowing at 100ks some doing 108ks but on the bike the slow lane traffic is flowing at up to 110 and many others are driving at 115. Last week two cop cars in convoy were travelling at about 105 and other traffic was flowing with them. I have checked the car with a Navman GPS and the Ford XR6 speedo reads 3kph high at 100ks. I have yet to fiqure out how to fit the GPS to the bike for a check of the bike speedo.

Has anyone checked the SV1000 or other Suzuki Speedos? I don't like going slower than the flow of traffic but would like to know when in ticketing speed.

That's a pretty similar error to most bikes. You can get a commercial electronic correction device but I don't know the details. Some of the other KB'ers have them so no doubt you'll get a response soon.

on average suzuki speedos have an 8-10% error (read high)

Check with a gps, or if ya know a cop with his radar gun.

If worrys you that much get a speedohealer to correct it, i have done this (i also did -1/+2 with sprockets) mine is now with in 1km/h at 100km/h

Cant help with Wellington, but in Aucks there are several speed readouts on Mt Albert Road, trundle along there with a clear space in front and see what it picks your speed up as. Note I'm not recommending trying to see how it reads at 100kph, just go for 50 and double it to get your margin of error.

Get someone to pace you in the XR6 ?

I have a couple of teeth up on the rear and use it as a buffer as far as speed,even then i think it would be less than 10% out.. SV and TL have the same system with a hall effect sensor reading off the output shaft.

I used the ACC trailer "your speed is " to test the TL its 99kmh actual at 100 so real close , assuming the trailer thingy is accurate , the SVs seem to have a little extra error , perhaps up to 5kmh

If it is anything like the ones I have seen, at speeds over 59km/h it will simply read "SLOW DOWN".

When I got my speeding ticket I saw on the speedo 132, when he showed me the speed he got me at, it read 124...

Moral of the story - I'm glad its out

Ah, perfect, so what your are saying is that my suggestion of "just go for 50 and double it to get your margin of error" will only fail if his speedo is out by nearly 20%.

Dennis, there was short thread relating to this a while back (here) in which I commented that my GS was almost 10% over-reading. Seems that it is quite common for m'bikes to be reading high.

GPS appear to be quite an accurate way to assess what a speedo is doing. Is your Navman hardwired into your car. I just used a Garmin handheld (strapped to the bike).

To reserect a old threard.

Just come back from my easter trip and found this to be the case in my SV as well, has anyone fitted on of these speedohealers on there bike and are they worth it?

[Cajun]

i have fitted a speedohealer to my bike

by using 8% error, + sprocket changed, i have adjusted my speedo to be with in 1km/h at 100km/h using a gps attached to bike

Why spend all that money? I bought a "Speedo Corrector" from Jaycar Electronics - does the same thing, but much cheaper.

It was pretty simple to put together, and easy to hook up once I worked out which wires to hook it into. It's now mounted under one of my inner fairing panels with 3M stuff (can't remember the name of it).

I bought mine not because the speedo was inaccurate, but because I lowered the gearing AND the speedo was off. I didn't worry about absolute accuracy, as my speedo's hard to read anyway, and 10km/h is about 4 or 5mm of needle movement. What I did is find out how inaccurate the VFR's speedos were, on average, added in the ~6% the new sprocket contributed to that, then adjusted the dials to give 12% adjustment. If I ever fit my standard sprocket back, then it's a quick click of the dials and it's accurate once more.

The odometer now reads low, but it makes up for the period when it was over-reading.

I know a few people in the US who have used Speedohealers on their FZ6s, which are about 10% high stock (I know they're used widely but FZ6s are my area of knowledge). They are pretty good, and I plan to get one myself at some stage, since I'd like to do a sprocket and chain conversion, and once that's done the speedo is high by a ridiculous amount. That Speedo Corrector looks like a much cheaper option, though. Does it come with a cover? Not all bikes are faired...
