step up to the factory pipe, aluminum flywheel, 44 mikuni, 8-15 skat prop by impros, Ocean pro steering and exit nozzle, and flame arrestor
that will make it hauls some assssss for sure
my 92 sx650 was really strong and i had these parts on it, also i personally loved it at 200psi, became VERY crisp when cracking the throttle
my friend had the same setup, except he went dual carbs, not sure what size, and my set up as about a ski length faster (bottom, mid, top end too)
only problem with the older skis is how well they were maintained, and ability to get good parts, i didn't think it was a worth while investment so i bought the SJ in 02
i do regret giving my skis away though, the parts on them would be worth a small fortune now
