    drop nozzle idea??

    Hey guys,
    I just bought a 2006 gp1300r and was wanting to do a manual drop nozzle setup (remove the quick trim system) as i am mainly building this ski up for surf jumping, but wouldn't hate a semi quick flatwater ski on the odd day it's flat!!
    My question is:
    In the pics below at the front cable rotor, could i disconect the up trim cable and put a compressing spring on the bottom cable bar (the one that goes to the nozzle). So trim is set at a position i like and then when i pull the drop nozzle lever, it compresses the spring and drops the nozzle and when i let it go it goes back to the set position??
    (pic 1 is when spring would be compressed, pic 2 would be when spring is at it's full length and trim is in it's set position)
    Or other option is:
    If i was to make a bracket that conects to the 2 top pump bolt holes and the cable runs through it. Then have an expanding spring from the bracket to the nozzle where the trim cable ataches so that when the lever is pulled the spring stretches, let it go and returns to a set point? (pic 3)
    Is this how the r&d auto nozzle system operates?
    Not to sure if i'm over thinking the idea or if it would even work, but if anyone has done this or something similar how did it go??
    Open to ideas and sugestions!!!!

    yes i have done that before, spring is good back up but nozzle will pull itself back to nuetral. if want it to return to slight trim up wound need heavy springs, and one on the nozzle too. will increase pull force required on lever but will work. i'll post up more about how i did it later. actually i am working on another trim system for my fzr. i have tons of pics about my old set ups

    I had the Riva drop nozzle on my 07 GPR...not sure they still make it...easy install..but never used it unless riding in the chop as it kept the nose down and you hooked up better...UNTIL I ported my engine and go fast mods!.....A night and day difference in the holeshot..

    May I ask, what exactly does all this mean? Drop nozzle etc? Why would you want one ? Forgive my ignorance.

    ... people angle their pumps and such to get the nozzles to angle up to get more speed out of the ski.. if you drop the nozzle it lowers the nose of the ski and keeps it planted more. so they are say night/day difference in holeshot being able to keep the ski planted in the water instead of wanting to jump out of the water. Or buoy racing where you hit a turn drop the nose turn and are able to have better speeds around a course.

    Does anyone know if you can still get this? My cable broke and I am having trouble finding a replacement.
