    You need an Advent CDI. Considering the temps and water condition your running a little slow. Your pump i sealed properly? Have you done any smooth water runs in cooler temps? Your rpm's are a little low also but the 101 temp is part of that.Try and run in smoother water and give us some new #'s.Were are the 2 washers in the plate located? How thick are they? You should be in the 67+ mph range.

    Where are the shims on your Riva plate. You really should'nt have any shims with a Riva plate. Step your sponsons and shim your trim tabs if you are trying to get rid of porpoising.

    how many turns out is your high speed screws?

    What kind of flame arrestors do you have?

    Did you disable your accellerator pump?

    Do you have v-force reeds or a pro-tec stuffer, cant have both?

    Your speed seems a little low

    with a 13/19 and your mods 67 is about what you should be getting.

    Ive got the V-Force reeds, and the protec spacer, my bad. The carbs are adjusted perfectly, the plugs are burning just right. Accelerator pump is disconnected. I am using the stock airbox with the front end removed, i play in teh surf too much to run F/A's. The washers are in the front mounts on the plate, and the thickness is 1/16th of an inch. im getting a little bit of a top end bog every once in a while and have been chasing it for a while and cant figure out what it is. Any other ideas?

    Top end bog would usually come from the carbs. You could be running rich or leaning out. Its impossible to tell you since we have no idea where your high speed screws are set. With flame arrestors they are usually set from 1 1/4 to 1 1/2

    since you have a tach are the rpm's steady at wot or do they decline?

    they are between 1 1/2 and 1 1/4 and the rear one is set about 1/8 more rich. ! WOT the RPM's kinda decline a bit after peaking

    Tim, if your RPMs trend down after peaking, you are too lean, come out on your high screws bit by bit until you maintain RPMs. When you are tuned right, you will reach peak RPMs and fluctuate +/-30 RPMs.

    You had better find some more speed unless you want my whale of a '99 3-seater to spank you. Come on up before the River and Beach Run and we will check you out.

    Cool. Smitty can get you going right. Check the pump shoe height and take a good look at that impeller.
