    Question Help With Problems!

    well everything seems to have gone smoothly,for break in, but i had to pin it a couple times before the whole 1st tank was gone, couldnt help myself..
    my dreamometer went up by 15 mph.... but i took the gps out and im only doing 65.3. .. my high speed t 's were screwed in a ways, so i loosened em up a turn and not much improvement.. i thought id be going faster than that, i need some help ?...


    im only spinning 6700 rpm @ 65.3.....turning a 14/20 with 42.5 cc domes...

    i need help getting my rpm's up so i can hit 70+ ?

    what mods do u need to know to help??

    Remy, list all of the mods on your ski. This will help with the "Big Picture".

    Make sure your power valves are adjusted properly.

    How does the boat run in general? Holeshot, mid-range, etc. Is is just lacking top-end?

    i made sure they were all in line when i hooked up the waveeater synchronizer things... if thats what you mean..... i have them set at i think snap 60 , and i can definitly feel when they open up

    i think it runs awesome, holeshot is killer,mid range is excellent,sounds like a baja, no cavitation at all... its so much faster than it was stock..dreamometer used to read 63 at most now it reads 77....i guess why im upset is that on gps its only 65.3 and from what i hear stock boats are doing that

    well buying the ski, learning about it, buying the parts, taking it all apart,putting it all back together, and getting the motor started is really half the battle...
    .i did that stuff by myself but now i need help for the other half.

    damn and i thought i was almost done for the summer with a 70mph boat

    Remy, do what WFO said and see if someone has a 13/19 you can buy or borrow. Maybe rapidacceleration can give you a hand with this.

    Neither one have produced positive topend results on this forum. They do add lowend power and have reduced weight but after tuning the jetworks mod and working with the different D-plates etc. the stinger pipes have long since outlived thier use. If you kept all your OEM exhaust we can help you get some real speed.

    Why did you add a return line restrictor? (this is normally built in to the OEM carbs)
