    Looking for more power on my 1990 waverunner 3

    I have a 1990 WRA 650 Waverunner 3 that i absolutely love. As slow as it is, its just so much fun and it just always works. I was thinking about trying to get some more power out of it but hopefully not lose reliability. right now its completely stock but i was thinking about possibly putting a pipe on it, throwing 2nd carb on there (its got a single 44 i believe), a nice SS impeller and maybe quick turn plate. If done right, can something with mods like that be built to be reliable? Can it also be something that can have pretty decent holeshot?

    What pipes would you recommend? what pipe impeller do you suggest and is a 2nd carb worth it? I got the ski for free 5 yrs ago and ive ridden the snot out of it for the last 2.5 and it hasnt complained one bit, is it worth starting to mod it anyway?

    Thanks for all your advice!
