    Speedo Accuracy

    Difficult question I know, but how accurate is the speedo's on the FZS?

    I assume it is dependent on a number of things mainly to do with the water conditions, but assuming dead calm waters would it be +/-5% or 10%??

    Is there a GPS or some other kind of device that can be used to measure speed and acceleration? Any recommendations welcomed.

    Thanks

    flyer67 i dont know of a pwc with an accurate speedo, as you said there are two many dependents that are always wrong,

    99.9% of guys on forum use a GPS system for speed logging as accurate numbers cant be taken off stock gauge for speed and gains from mods added,

    there are plenty of gps systems on the market but many including myself use garmin etrex as there a great little bit of kit for not a lot of money
    you can start at about $80 and found on E bay and many outdoor stores

    Anyone ever used one of these GPS Speedometers on a ski?


    IMO it won't replace a digital GPS unit with recordable top speeds but would at least be an accurate speedo to look at when the handheld isn't mounted.

    A good, reasonably priced, combo is a "Garmin eTrex H" + "Garmin eTrex Marine Mount" (I chose to use only portions of the marine mount to keep the overall height down). You should be able to pick up both for <$100 total if you shop around.

    I looked into GPS speedos. Livorsi & Gaffrig both make marine GPS speedos with re-callable highest speed.

    However, there's no more functionality than a handheld and they're 5x the cost. Also a big mounting hole is required for even the smallest (3 3/8") speedos.

    It's not my thing--I use my tach going through the 10 mph lakes as my speedo hasn't worked at all since I shimmed it.

    It just seems some here want a speedo that's accurate.

    in stock form the speedo's are not to bad probably +or- 5
    but as soon as you do mods the speedo seems to go way off , for exampleon my fzs
    the speedo was withing 3 kph of the gps when stock
    after mods it is reading over 85 mph when i am doing 72 mph on the gps
    so a gps is the only way to go

    +1 the speedo on my stock fzr is usually +4 of gps.
    Shimming the plate will also greatly increase the inaccuracy of the speedo.

    When my FZS was stock, the speedometer read 5 mph higher than the GPS. After the VX rideplate was installed, it reads 10 mph higher than GPS.

    It would be nice if someone would come up with a converter that would take a GPS output and convert it to a signal the stock speedometer display could use.
