    I dont belive it has a setback pump , but the entire intake gullet/intakegrate/jetpump are located further towards the rear of the hull. Setback pump is made by skat trak and is a pump design feature.

    skat trak pump

    matter of fact i just looked at the skat site setback article and it confirms that the veins are not moved back but just shortened. Also mentions hookup improvment because of the additional stored water in the intake gullet.

    skat trak pump

    The setback has shorter veins than the regular. The length is taken off the front which allows the impeller to be further back . So it does have to do with the length of the veins.One reason the veins are shorter is that it reduces drag allowing for slightly higher speeds at a given rpm with no...

    Fuel Tank Mod!

    I used the KBS coatings on a carbon fiber motorcycle gas tank as recomended by KBS and it worked well . The muratic acid in the kit was not used but the etcher was , only the procedure was a little different than with a metal tank.

    What else can cause a rich condition?

    Last night while running the SJ with the arrestors off in the garage i could see a steady stream of gas flowing from the primer , two year old bulb type primer. I had been ready to tear the engine apart and It sure is good to find out the problem with a ski will only cost $20 to fix.

    Do you have ecwi hooked up and working ? It is a must have for the dry pipes and they will make good power with the right setup.

    Good deal on a CF Freestyle Hood

    That BCW hood looks like one I have had since 99 , except for the cheesy handholds . Mine weighs 9lbs and is well made. I always taped up a couple of the air inlets when going into the ocean with it . It also needs some dryer hose on the inside to channel any water coming in , down and away from...

    x-metal waterbox

    I just weighed my stock 2000 waterbox on a postal scale = 5lbs , so 3 lb savings + water with this x metal box . It sure is a tight fit getting it in and looks like I will have to cut a few inches off the stock long hose. Also put on a new stock hood gasket and the battery out of a yamaha R6...

    detonation sensor

    sp125racing.com has a link to some detonation sensors that could possibly be made to work if you got two , since they are for single cylinders. These are a must have , if you really want to know what you motor is doing.I cannot belive they have not become mainstream in watercraft tuning.
