hey ive got a question about the 15f stock speedo. gps my ski will run 69mph. the stock speedo will go to 70 and then drop back down to 64-65 but the gps keeps climbing. is kawi so out to please the coastguard that they somehow control the reading the speedo will attain and drop down after 70? by the way stock my speedo said 69. ive added 8mph(gps) on that and it still reads nearly the same? just something thats been bugging me because all i ever here is how stock my friends rxt does 74mph on his dreamometer. its annoying lol my rant is done.
