Long time seadoo fan and sadly had to let go of my 1999 SPX because of the Lame 2 stroke law passed in here in Nevada for Lake mead. My beloved SPX was my 3rd X4 hull ski and was pristine with the following mods: Trim tabs, prok flame arrestors, beach house sponsons, jettrim seat, intake grate and prop. I picked up a 60hp spark and am getting it setup this winter and am hoping to replace the fun I had on the SPX. Has anyone in the forum gone from an X4 to the spark? Your thoughts? I am going to get a VTECH tune, I dropped the sponsons and am thinking of trim tabs and R and D intake. Any feedback would be greatly appreciated! My current rides are: 2004 RXP, 2001 RXDI, 2003 XPDI, 2014 Spark.. Thanks!
