    Ride plate, Pump seal kit, intake, exhaust, advanced timing plate, block off's, and prop repitch, fresh oil and plugs and you will be around 59mph.. thats where my ultra lx is currently with those mods

    What he said is about all they have out and all you can do without getting crazy. We have similar setups but I have to ask you what type of areas you will be riding.
    Reason I am asking is... as you can read from any of the Ultra threads, you will sacrifice your rough water riding by getting the extra speed. I change my setups quite often depending on where I am riding. Around the house on the lake I have one but when I head out to the beach house for some offshore riding I change it completely. Much slower but needed for those conditions.

    If you do anything to your air intake DO NOT just throw on a filter on the throttle body. If you look right on side of where your filter is, there is the drive shaft coupling. Get any water in your hull it will get slung right into your filter meaning water in your engine.

    Most of my riding is in a river and around beaches, also what does the pump seal kit achive,
    the main reason i ask is that my friend has a 06 stx15 and he averages about 10km/h quicker than me and i wanted to keep up and also do you know the reason why the speed difference is it just weight of the ski

    thanks

    yes the weight has a bit to play

    But mainly the shape of the lower hull, Yours is a Vee shape
    his is more flat

    Vee shape better suited to rough water...............and not conducive to easy speed
